The REAL Difference: Made in China vs Taiwan

[@ShopHumor]

Thanks for watching!! Here's the two chucks in the video: - *No Balls Ball Bearing Chuck:* amzn.to/3YlBkpW - *Vertex Chuck:* amzn.to/4eYsJzg More links in the description. THANKS AGAIN for watching and all the comments. The MYSTERY CHUCK has been identified by a viewer, @jasonpoletta1797 as a 10062 or 3303-078. Don't have a link to a US retailer for it unfortunately. Thanks!!

Just patch the hole and refill it with chuck sauce, it will be good as new.

[@stevepetrosino1590]

You did not say and I am not versed well enough to tell from the vid. Were they designed for balls? If so, could you add them? And would it be worth it?

I would buy a second one on HHIP for another video to see if they fixed the problem!

[@dongleseon8785]

Sounds like a happy customer experience but it might be the repertoire that they use to anybody that brings it up. They don't loose anything. They just need to give a refund to few that opens it and keep selling neutered chucks to other customers.

I talked to the HHIP rep at IMTS and handled a bunch of chucks and other tooling. I was impressed all around. Glad to hear they are treating people well. I’m going to try some of their stuff next time I am buying.

[@kurtg5645]

Guys, as a Chinese person, all I can say is that most of the time you get a bad impression of a Made in China product is because the company that sells you the product jacked up the price way too much. For example the chuck shown in this video, B18 drill chuck usually cost about 10 bucks here in mainland China, and that's with shipping. Even jacobs B18 chucks, usually does not exceed 20 bucks range. Think about it, if you spend 70 bucks on a chuck and less than 10 bucks is going to the actual making of the product. There will 100% be expectation and reality drop.

[@ShopHumor]

I think Chinese tools have a bad reputation due to more significant quality issues from back in the 80s. In my experience, Chinese tools are really not that different than tools made anywhere else - you can get really good ones, or really bad ones. One of the things I wanted to do was evaluate the machining and precision of a made in China chuck to compare to a made in Taiwan chuck, and while the internal machining was distinctly worse on two of the chucks compared to the third, the performance / accuracy was fantastic across the board.

[@ken481959]

@@ShopHumor Well, the issue is this: the Chinese will make anything you want, to any price point you want. And they will do it well. If you want a cheap item, not too precise with fit and finish, they will do that. If you want something precision with much better fit and finish, made from specific materials, they can do that too. The question is how much do you want to pay for it. Just like with Western companies. But you better supply your own engineering. While they are getting better, they are still not really up to Western standards, and part of that goes right back to the Cultural Revolution concepts. But that is a different topic.

[@ShopHumor]

It's absolutely an incredibly complex issue indeed. Eventually I'd like to source an old, USA-made Jacobs Super Chuck and compare it with a brand new, China-made Jacobs Super Chuck, and then compare those two with a cheap, unbranded China-made ball-bearing chuck and see how they all compare.

[@fredio54]

Don't forget ROHM, and there are other makes too. The issue with buying anything Chinese aside from hit or miss quality is that it supports arguably the most evil government in the world the CCP and their weapon the PLA. Fight with your credit card now, not a rifle later.

[@lowrads3653]

Many products from China are better than American products these days. It all has to do with scale and learning curves. I'm sure there were some oldheads in the UK that still thought the same about domestic products for awhile, but there aren't too many of those around now.

[@rickshoop2063]

When checking run out on a drill chuck, you want to check it with a smaller than maximum size drill. The idea here is with less of the jaws being supported by the body of the chuck, the precision of the holes that the jaws ride in will manifest itself. Besides, run out on a maximum size drill is far less important that with the teeny tiny drills we sometime use. The advantage of the ball bearing chuck over a plain bearing chuck is less friction is lost on the rotation of the collar to tighten the drill. So for an equal amount of force on the key, the drill is gripped much tighter. The second advantage is long term accuracy. Since you do not have two parts sliding over each other the amount of wear of the collar is reduced. When shopping for drill chucks, and I have a choice between a new plain bearing import chuck and a used, rusty, obviously well used Jacobs ball bearing chuck, I will pick the Jacobs and just clean it up.

[@ShopHumor]

Good tips, thanks for the feedback!

[@chigger68]

I bought a jacobs chuck 2 years ago. Paid full price. I damaged it and bought the rebuild kit. The new parts didn’t fit. Called jacobs and found out that the new chucks are now made in China and the rebuild kits are only for the older (non-Chinese) chucks. All new jacobs chucks are Chinese and they are considered disposable, yet the customer pays full price.

[@Stealth86651]

If I understand correctly I imagine it's also a lot easier to replace a worn bearing than it is to replace one or two sections of the chuck itself as well. Assuming the time/cost is worth it, don't do shop work so no idea on the actual time and cost of a repair like that over just buying a new one.

[@ats-3693]

I work for a company that flys large helicopter UAVs on long range geophysical survey missions, we source our base drones which we then modify from Taiwan and China and Korea. What we find is that you simply get what you pay for regardless of the country of manufacture, pay for a cheaply made and priced product that's what you get, ask for and pay for a higher quality more expensive product and that's what you get. Everyone has this attitude that China sells cheap crap, and they do if that's what you want to pay for, but they can and will and do manufacture to whatever standard you require, if you want high quality you have to pay for it.

[@ShopHumor]

I’m 100% sure you’re right - you absolutely get what you pay for no matter what or where. I do wish it were easier to source the high quality stuff without having to trust importers

[@talesmaschio]

True. The price never lies.

[@ats-3693]

@@ShopHumor Exactly, most of the cheap garbage Chinese products that people complain about have been imported by an importer in their country who ordered and paid for a container of cheap garbage products which they then mark up and sell for a profit, the Chinese manufacturer has just made the product at the quality level and the cost the importer requested, or it's stuff people have found online and imported themselves. You get what you pay for, any western importer/distributor can go to China and meet with a manufacturer and order a product to be manufactured to whatever quality level they wanted, but of course higher quality will cost more and be more difficult to sell and make easy profit on. We import our UAV's directly ourselves from a manufacturer usually after someone from our company has talked at length with the manufacturer explaining the level of quality we require, and sometimes one of our guys will travel to China or Korea to visit the manufacturer and discuss this.

[@brianwest2775]

What we're wary of is paying an inflated price. Is the $30 item better than the $10 item or did that seller simply inflate the price of the same $10 item?

[@ats-3693]

@@brianwest2775 I mean as far as low quality Chinese products imported and sold by a seller in our country's I think that's obvious, depending on the product and the volume of them the importing is bringing in and selling they are usually make huge profit margins and also giving everyone the impression that Chinese products are overpriced for their quality. If you go online and look for the same products for sale in China from their manufacturer the price is usually very low. I live in Bali Indonesia and through Asian online shopping apps I look at and sometimes buy products for sale directly from their manufacturers in China or even online sellers here, the prices for all sorts of interesting gadgets and products are crazy low, like so low it's not an issue to just buy an item to find out if it's any good or not.

[@robinlu4029]

In China, we use these kinds of chucks for the not percesion jobs like drill a 10mm hole for (+0.1/0).If you need good runout, we usually use a ER collect to hold the drill instead.

[@ShopHumor]

These gave really good precision for drill chucks (better than .001 inch so .025 mm) but I don't ever really use drills for precision. What I do is drill the hole undersized to my final dimension, then use a reamer, end mill, or boring bar to bring the hole to its final size.

[@robinlu4029]

​@@ShopHumor Sorry for my poor english. Due to the intense competition in China machining industry, in order to make money, you must produce a large number of high-quality products that meet the requirements in a short period of time, which makes it necessary for us to conduct research on this. If you need percesion holes, i highly recommend trying the NACHI 7572 drill. First, it features a high-precision integral cylindrical shank, which is ideal for precise clamping in ER or hydraulic chucks, a foundation for machining accuracy. Second, its optimized cutting edge design allows the drill bit to position accurately when entering the workpiece and offers excellent chip evacuation. I've successfully drilled IT6 holes on a common machining center using this drill with an ER collet holder.

[@ShopHumor]

@@robinlu4029 thanks for the suggestion!

[@robinlu4029]

​@@ShopHumor Overall, I want to point out that China also have reasonably priced and high-quality tools, but it's difficult for foreigners to buy them because those engaged in foreign trade are just looking to make money. They don't care about the quality of the products customers can buy, as long as they are usable.For example, low-quality BT40-ER32 is sold for only 35CNY or 7USD, and ER32 collect for just 7CNY or 1 USD. It's not that they are unusable, but due to the lack of dynamic balance and the use of inferior materials, they are fine for rough machining on machines below 8000 rpm. However, over time, the precision deteriorates. High-speed precision machines require tool holders with precise dynamic balance, which can generally be purchased for 150 CNY, and their quality is not at all inferior to the 400 CNY tool holders produced in Taiwan.

[@AlanMydland-fq2vs]

most collets are the best next to albright

[@melgross]

It’s not just the accuracy. The ball bearings allow much greater clamping force. These “errors” are because they are just shippers of products from whatever gives them the lowest price at the time. So when the looks of the product vary, that’s why. When they run out of current product, they replace it with whatever they can get at the lowest price. It’s a shame, but Banggood does that, Vevor does that and others such as HHIP do that. Now, Vertex is usually a higher quality brand, so it’s surprising that something with their name on it isn’t right. MSC industrial has their products. If you get it from them, you know you’re getting what you ordered. For others? Well, maybe they’re not real Vertex products. I have a bunch of surface grinder hubs I bought from HHIP. They look great and are machined and finished well. But they say they are hardened, but they’re not really. I found out as I had to open the taper up a bit.

[@ShopHumor]

I'd really like to get an actual made-in-China ball bearing chuck and compare it to a nice old Jacobs Super Chuck to see how different (or not different) they are. You're right about the greater clamping force for sure. A big plus. I was also surprised about the Vertex -- one of them being such high quality than the other, especially comparing side by side with the poor-quality Vertex and the unbranded, made-in-China chuck. The "real" (if they're not both real) Vertex was machined so much better.

[@melgross]

@@ShopHumor I have several sizes of the Jacobs models and they’re pretty good. I use them in the lathe as I rarely use chucks on the mill, usually ER-40 collets for the larger size bits and DA versions for the smaller. Both have 0.0002” concentricity and are much more reliable. If you really need accurate small, under 0.500” holes, say, you can get bits of decimal sizing. I don’t know how important it is to you.

[@ShopHumor]

.0002" is pretty dang good. I have a few projects coming up that will need small holes, but I don't know yet the exact dimensions I'll need... we will see. I'm going to be picking up some ER40 collets pretty soon now that I have ER40 collet blocks in the shop...

[@UncleKennysPlace]

It might be fun to try pins or drills throughout the ranges of the chucks to see if they remain accurate. I just bought a "precision" Chinese keyless, and was surprised that it had ~0.001" runout. I'm good with that.

[@ShopHumor]

That’s a good call on testing different ranges to see how they perform throughout their travel range. And 0.001” seems great for 99% of drilling operations.

[@Kami8705]

A pin would also be nice because you could measure it further out where a drill bit tip would be and where the runout would matter. That few thousandths at the base could be far more exaggerated at the bit where you're trying to line it up with your mark

[@ShopHumor]

@@Kami8705 I thought about that and I agree that would be good information, but I also wanted to measure as close to the jaws as possible to 1. minimize error / maximize consistency between setups and 2. I believe the accuracy rating that the manufacturers supply is measured at the chuck jaws. All good points and suggestions for the future though.

[@dancoffey8412]

Very interesting disassembly process. I am certain that I would mess it up, but it is great to see it done. It would have been interesting to see a real ball bearing chuck. Thanks for the hard work of putting the video together.

Thanks for commenting! I completely agree and I cannot wait to get my hands on some ball bearing chucks. I am going to be doing a follow up video to determine if the distributor has actually fixed this problem, and then I'll be comparing the cheap China made ball bearing chuck, with a brand new Jacobs brand ball bearing chuck (now made in China), and an old, vintage, USA-made Jacobs brand ball bearing chuck.

[@joshua43214]

Buying stuff like this from Amazon is dumb. Even if you go to the manufacturers store, you will still often get a counterfeit. Either because someone returned a counterfeit in the box, or because Amazon fulfilled the order and mixed in counterfeits. Learned this the hard way on a few items, I always go to an authorized dealer like McMaster Carr. Moral of the story, if it is cheaper on Amazon, then it is fake.

[@ShopHumor]

Amazon giveth and Amazon taketh away. There's a lot of good stuff on there but you definitely have to be careful. Luckily their returns are easy if you get something disagreeable. I ordered my 'ball bearing chuck' in the video from Zoro, who I've had good luck with, but they drop shipped it directly from the distributor themselves (HHIP). The service I got from HHIP was fantastic and I'd highly recommend them. Imports, whether they're from Taiwan or China, are often inferior to the stuff we'd find on McMaster-Carr, but they're also a lot more affordable. If they manage to do the job you need them to do, at a price you can afford, that's a lot better than not having the right tool for the job in the first place because you couldn't afford what McMaster was offering. I buy a lot from McMaster, but I also look for value whenever and wherever I can. Thanks for commenting!

[@ken481959]

@@ShopHumor the question is this: How precise do you need it to be? Having done QC/QA over the years in both civilian and military, conventional and nuclear applications, the amount of precision needed is what determines the quality of the tooling. You can spend a lot of time, money, and effort trying to make something to within .0001" when +/- 1/16'' is really good enough for the application.

[@lowrads3653]

Yeah, Amazon shuffles materials from their different suppliers together at the warehouse, so it's impossible for reputable dealers to maintain quality when selling through them.

[@randyfender6122]

I've found that, in general, made in Taiwan stuff is more often higher quality. As for buying from Amazon, there is info 7nder the add to cart button. From what I've seen, if it says Shipped From:Amazon then any returns are typical Amazon returns. AKA I typically walk into Kohl's (or Staples) and return it. No box needed. They scan the QR code that Amazon emails me, take the item, and if I choose to take the Amazon credit (always) it shows up as a gift card balance in a couple hours. If not shipped from Amazon, you may have to box it, ship it back with UPS, FEDEX or USPS. Much more of a pain. I'll pay a couple dollars more j7st to avoid that on the off chance I'll need a return.

[@michaelbriggs4884]

Interesting results! Besides runout from the axis of the drill bit being offset from the mounting axis, there could be runout from the bit being tilted. I suggest measuring runout by using a dowel pin or drill blank and indicating away from the chuck jaws.

[@ShopHumor]

I like the idea of measuring with a dowel pin or drill blank at a set distance away from the opening of the jaws as well and will incorporate that into future testing. I plan to (eventually) source cheap ball-bearing, made-in-China chuck and compare it with both a brand new, made-in-China Jacobs Super Chuck and an old, USA-made Jacobs Super Chuck.

I don't have a mill, just a 14 inch Delta drill press. It's got a 5/8 chuck. 2 1/2 inches down from the chuck, measured .002" plenty good for my needs. The mfg date is 9922 which I assume was 1999, September 22. It's got the original Jacob's chuck. I paid $210 at a local tool store. I tapped the chuck up into place when I set it up. I've never removed the chuck, but assume I cleaned the tapers pretty well, so the runout has to be the chuck. I don't use it daily, but I can't imagine life without it. HF had two returned drill presses by the cash register. Might have been a 14 and 16. I can't believe how much a low end drill press costs these days. I'm quite happy with my antique Delta.

I would have liked to see a longer tool chucked up and measured for runout than the drill. Like a gauge pin measured an inch or two out. Ive had chucks that have little to no runout right at the nose of the chuck but hold the bit at an angle and they are all over the place at the tip of the drill.

[@ShopHumor]

Thanks Reini. It's a good suggestion to measure both at the chuck jaws and further from the chuck jaws. Someone else suggested that it would also be good to measure with different diameter pins/drills as well, to see if there's a variance between the minimum and maximum capacity of the chuck, and I like that idea, too. I plan to do a follow up video comparing a brand new, low-budget, China-made ball bearing chuck, a brand new, high-budget, China-made Jacobs Super Chuck, and a vintage, American-made Jacobs Super Chuck, just to see how they compare. I'll incorporate those suggestions into that video!

[@raybod1775]

Importers refuse to pay for better quality Chinese products, so they get the cheap versions. China does make great products.

[@ShopHumor]

Where do you go to source the great quality products? Surely there must be some distributors for them

[@jfan4reva]

Yes, they can make good stuff, but unfortunately most of the tools that get imported into the U.S. falls into the "Chinesium" category, with the importer not wanting to risk losing money by importing better quality stuff that will still be classified as junk in most people's minds.

[@dallassegno]

So... the Chinese export inferior products intentionally. How trustworthy.

[@Baroque_Back_Mountain]

There is some very precision tooling available these days, for cheap. You should check out the reviews for the $50-ish machine vise that Vevor sells. They are machined really beautifully, where it matters, they’re robust, and the tolerances are way way way beyond what they should be for a cheap $50 vise. …same with Vevor rotary tables, they’re smooth running, and just so much nicer than what you’d expect for the money. I’m going to buy one of those mystery chucks…that thing was beautiful inside. 👍👍👍 thanks great video

[@smoking_monk3257]

I do my best to buy Taiwanese tools, quality is always better and the cost difference is negligible. My Taiwanese pencil grinder just won't die, I've probably oiled it twice in 5 years, definatly dropped it in the wire edm tank a couple times. Honestly it's the best value for a tool I've ever bought.

[@ShopHumor]

I've been looking at a Taiwan made Precision Matthews milling machine for a while. I already have the PM-25 from them and I love it, but it's a CNC conversion now and I'd like to get a heavy duty manual machine too.

[@benjurqunov]

Same here. For budget friendly wrenches, sockets, etc. I've always had very good results with Taiwan.

[@jasonwood7340]

We ordered an accupro chuck that was hard to open/close right out of the box. It got to the point after a couple of weeks of use that we had to use the chuck key to open and close it. We ended up getting another new one so I cracked open the old one. There were burrs inside left over from drilling the passages for the jaws which had destroyed the cage (plastic) for the ball bearings. The new one feels exactly the same as the one i dissasembled. Very disappointed.

[@ShopHumor]

That's awful and I agree, very disappointing. Those burs can really mess things up internally

[@djfaber]

A few comments on future accuracy tests. 1) measure the TIR of your spindle, then arbor first 2) use a precision ground pin instead of a drill bit 3) use a tenths test indicator Cheers!

[@ShopHumor]

Thanks for the feedback!

[@ken481959]

My question is how well these chucks hold up over time. Especially the jaws that actually come in contact with the bits. Are they fully hardened and then precision ground to each other in the chuck, or are they simply assembled from a box of parts? What do you think?

[@ShopHumor]

I think time will tell. I suspect that the mystery chuck that was machined so well is probably going to hold up fine, but the other two I'm more curious about. I plan to (eventually) source a cheap, knock-off China-made ball-bearing chuck and compare it with a new Jacobs Super Chuck (also now made in China I believe), and an old, USA-made Jacobs Super Chuck. I could revisit these chucks then and see how they've held up.

[@jpowellfed]

Made in Taiwan ❤👍

[@randymagnum143]

We received the assets of a failed machine shop. In a lista cabinet was an entire drawer of the kinds of chucks, new in box. We have a nearly lifetime supply of good, but ancient Jacobs chucks. The chicom stuff went in the scrap hopper.

[@ShopHumor]

I just bought one of the new (now made in China) Jacobs chucks and am going to compare it to the old vintage USA made chucks and see how they've changed.

[@shermangriffin2722]

Ive definitely used these chucks at my shop, while I'm not worried about run out so much when drilling a hole for the parts I make most of the time, I have found them to not hold the drill very well and have spun in the chuck multiple times, I have to torque it with a pipe on the chuck key to be safe.

[@ShopHumor]

Which chuck do you find grips best?

[@shermangriffin2722]

@ShopHumor I have used older chucks that's were legit Jacobs, I noticed the portion that grips the drill has a little bit bigger surface area and I've never had a drill slip with it.

[@ShopHumor]

Yeah I like the older Jacobs chucks too. I'm actually working on a comparison between vintage Jacobs chucks (made in USA) and the new ones (now made in China, still Jacobs brand) just to see how they hold up now compared to the old ones.

[@BushiM37]

Would the cleaning and deburring affect accuracy?

[@ShopHumor]

I think so because I think if a jaw is contacting a burr, it's going to deflect the jaw some amount, and the inconsistent grease could easily attract grit and grime over time that would cause a similar issue. A few commenters suggested I ought to have done a pre-maintenance accuracy check and I plan to incorporate that into future comparisons.

You ordered the vertex castrati models, they also make a higher pitched noise during use

[@williamemerson1799]

Excellent! When these things go back together do the jaws have to be indexed?

[@ferrumignis]

Yes the jaws must go back into the correct location, just like a 3 jaw lathe chuck.

[@ShopHumor]

Typically, a Jacobs-style chuck jaw does not need to be indexed prior to reassembly. They’re designed with self-centering jaws that should align correctly when reassembled without specific indexing. When re-assembling I do always mark mine to put them back where they came from. I’ve seen some chucks with jaws that came numbered from the factory, but most I’ve seen haven’t been marked.

[@Owjdnskoakansbskk]

For me I would choose made in Taiwan because I used to live there and I’d rather support manufacturing in a democratic country that doesn’t commit human rights violations.

I used couple of vertex vices and er collets, for pro work. No quality issues to speak of. One of the shop I worked at had 18 machines kitted out wiht LEAVE base plates and maybe like 50 vices in total their quality was actually rather impressive. Ps when your checking run out I would recommend using ground bar and checking it atleast 50mm from the face of the chuck

Interesting comparison. I have a few Vertex tools in my home shop (in the UK), including a dividing head. They all have proved to be adequate and good value. The finish on machined parts is very good. I think all tools, wherever they comefrom benefit from a strip, debur, clean, re-lube and careful reassembly.

[@ShopHumor]

Thank you! I agree with your practice - strip, debur, clean, re-lube, and careful reassembly. That's always been my procedure as well. Glad to hear your experience with Vertex tools has been good. I plan to get more (eventually).

[@schmiddy8433]

You got the wrong one because if amazon thinks two sellers are selling the same exact item they will merge the listings and just send you whichever one is closest. This means even if you go to an official store page on amazon, click their listing and click buy amazon can send you a third party "reseller" (counterfeiters) item instead.

I always check runout with the indicator located, 1 inch from the surface and use a dowel pin or gage pin.

[@ShopHumor]

I've had some good feedback on refining that testing methodology (including, as you suggest, a dowel or gauge pin), as well as measuring at the top of the pin closest to the jaws, then at the bottom of the pin to see if there's a difference in runout between the two. Thanks for commenting, I really do appreciate the feedback because it will help future videos.

[@kevinvanderlei3271]

Great video, thanks!

[@AaronRigali]

Im not positive on this question, but wouldnt you want to check runout on the end of a bit that was actually doing the drilling? If i understand correctly, the runout would be greater at the far end. Right?

[@ShopHumor]

It would be good to check on both the top and the bottom, and also good to use a more purpose built measuring tool than just a drill bit. But for cheap chucks I figured it would get us in the ballpark. I plan to do a follow up video to make sure that these guys corrected the problem and I'll improve my testing methodology then.

I do personal car/autobody projects on the side. My personal feelings on made in China products, is not that everything is of poor quality; it's rather more that it CAN be. To put a finer point on it, I have little to no guarantee of the quality in the product I'm buying. So it could be great, or it could be terrible. It's the international toss up, where shipping wait times are high.

[@ShopHumor]

I am certain there is really high quality stuff being produced in China... their sheer size almost guarantees it. It's just really hard to know what you're getting before you buy it over here, as you noted. And I think a lot of the importers are buying the bottom of the barrel stuff to save a few pennies per unit

[@chrisc3118]

I used to audit manufacturing companies in China and Taiwan and hands down Taiwan has much better quality overall. Taiwan is on par with US manufacturing quality, perhaps slightly lower quality than made in Japan products. The challenge with made in China products is the amount of non-compliance raw materials used as well as sub-contracting to back-alley suppliers. Those happen more than you realize and most customers are not aware. I encountered a number of these issues during my audits. Many heavy manufacturing suppliers in Taiwan are sorta unique in how they operate and will drive an auditor crazy because they don't follow precise processes or procedures and paper trails are hard to gather yet they get the job done somehow, mainly due to a very well trained, experienced workforce that has been making machined parts for their entire careers. I prefer US made, Japanese made and Taiwan made. My last choice is China made and typically consider products made in China as one time use e.g. disposable.

[@GreeceUranusPutin]

One thing to look out for when shopping Amazon is that people will buy a product and return their old or defective one for a refund. Then, Amazon sells the returned product to a new buyer, having no clue that it's been switched. I don't blame Amazon warehouse employees for not being able to catch this or even care.

Yep. I’ve had that exact thing happen to me. Actually the last one off die I needed was clearly rusty and used when it arrived - there was lots of wear on the teeth of the die and metal shavings stuck to them too.

It is made in such a way that it is relatively hard to damage- the indicator body is sprung against the face and can give. It is so sensitive that even though mine has its small ticks at .001", I can count on repeatability to .0005, because there is so little internal friction in the mechanism. The arms clamps and joints, though simple, are much more precise and smooth. I got what I paid for, after 25 years nursing along a Central Tool unit I bought for $60 in 1997.

I've upgraded one of my bikes (a folding bike, but not just _any_ folding bike - a super-rare, full-suspension Dahon Jetstream) with a set of MT420 calipers/MT401 levers and they are impressive. I had another set of 420/401 on my other folding bike - a Dahon Hemingway, which is my daily rider and errand runner - that originally came with puny pads the size of a quarter (BB5, and the calipers aren't even real BB5s) that just didn't cut it. I took the 420s off after a while because they were just too powerful for everyday use on a bike as neutral and as mild-mannered (despite the name) as the Hemingway. Now I'm running mechanical Tektro Aries on the Hemingway and I couldn't be happier. I'd ordered the MT200s because I already had a pair of new MT201 levers and new BH90 lines - which would've made for a nice hydraulic upgrade, but Amazon just had to stick a rod in my spokes!

I would not assume that the seller "making it right" in your case meant that they fixed the problem of balless chucks being sold as ball bearing chucks. In my experience, I have seen this tactic: They sell some item with false descriptions, such as "genuine leather" or other materials, or "a million candlepower" type claims, or for a purpose other than it is advertised for (part would never fit your use), or the item is defective and poorly made. Then, when you complain, they pretend to appreciate your bringing it their attention, they claim they will fix the problem, and they will give you a complete refund... or whatever to make you happy. But this DOES NOT mean they actually fix the problem! I think it is cheaper for them to settle with the very few people who will notice, or care, or not think the problem is their own, and continue to sell the items on false pretenses, rather than change up their whole line. Think about it: How many people are disassembling these to see if there are actually ball bearings in there, or not? How many people test candlepower, or know fake leather from real? Probably for every ten complaints, tens of thousands of the item are sold with no complaints... I'll bet if you bought ANOTHER one from the same vendor... if you do, use a different name and address!... it would ALSO have no ball bearings in it.

[@ShopHumor]

It's a real problem, and you could be right. I do plan to follow up on it in the future to see if they've fixed the problem, but I want to give it enough time for there to be no BS excuses about supply chains and old stock inventory. My plan is to compare a vintage, USA-made Jacobs Super Chuck to a brand new, China-made Jacobs Super Chuck since they moved manufacturing there, and then compare both of those with one of these no-name, unbranded China-made ball bearing chucks to see how all three compare.
