I no longer even shop around for sand paper, cut off discs, abrasive discs etc. If it says 3M/cubitron I bite the bullet and buy it. They just work so much better and longer.

[@MrTheHillfolk]

As I'm nearing the end of a car build, I gotta say I'm a big fan of 3m. If there products don't work right ,you're doing it wrong or using the wrong materials. Sure it's pricey, but I can only afford to do this once. Might not be a fan of all the toxic crap that's left over from their chemical production , but their products just flat work.

[@tonyfnd]

I use the 3M Cubitron or the Pferd stuff. They both just last forever and are well worth the money.

[@codyswilley]

[@davidfarmer]

bro, that's not cavitation, if anything its chatter. cavitation is when gas bubbles form in liquid because of change of pressure. Definitely going way too high on the rpm, the bristles shouldn't be flaring out like that.

[@phillhuddleston9445]

A 5 minute video spread out over 23 minutes! 3M for the win for anyone who doesn't have time to kill.

[@pgmurray76]

SHOCKER!! hahahaa sorry

[@blackjackfabrication4043]

Cavitation is the wrong word. This guy needs to look up the definition.

[@justforkiks29]

Ford calls for white 3m bristle disk to clean mating surfaces. The 3m disks run circles around the knock offs.

[@MattLitkeRacing]

I work at a Kenworth dealer. Paccar requires the white disk also

[@k.beeler4240]

The reason the Amazon disks are "cavitating" is, they used a cheaper plastic. It's getting hot quicker and the hot plastic is grabbing the surface you are trying to clean. 3M's version must use a plastic with a higher melting point.

[@glennjames7107]

They have to be, because I've loaded them as hard as you can with a pneumatic, right angle, die grinder, Dotco brand, and they would never melt. Usually you can tell by the transfer of material from the bristle disc, to the aircraft skin. But they didn't mind. They don't work efficiently at high loads, or high speed. They work best if you don't spin them to point that they are starting to flare out, at least that's been my experience with them.

[@JosephArata]

​@@AlwaysBeSmart674 they're not, it's made from hard nylon with aluminum oxide mixed into the injection plastic.

[@calvin.miller]

the rol-loc discks have a firm backing pad that the disc's attach to. The Amazon brand has its own built-in flimsy backing pad that allows it to flex more than necessary which causes cavitation

[@Prevailingbucket]

Why are we even considering anything from China? Why????

[@GTRliffe]

i always pay extra and buy the better one. not just the quality but more self pride and class is attached when quoting work. Getting paid allot when skimping on quality slowly degrades your self worth. you end up feeling wrong and the client can hear uncertainty in your tone. paying extra usually improves your memory too, you don’t missplace as much

[@Justin-C]

Why are you going so fast, especially on such harsh corners and sensitive surfaces? Those speeds needlessly beat up both bristle discs and the work surface. The amazon one was pretty clearly outclassed at high speed the moment you went full bore (which might make the 3M one better at high speed removal), but that doesn't mean it won't work great to slap on a drill to knock some rust off for maintenance/welding/restoration. Too bad 3M doesn't sell inexpensive 3 packs (1 of each)

[@melgross]

I haven’t used the cheaper ones, but the 3M is really good, and lasts. The Amazon green copy has parts of the bristles coming off on the second test. With the permanent (it looks) splaying and the breaking off of the bristles, it doesn’t seem like much of a bargain. I don’t see a reason to stop using 3M. Often there’s a reason why something costs more and it’s not because of the brand name, it’s because of the quality. It’s usually because of the quality as to why a company becomes a brand name in the first place.

[@jkohutiak]

this video makes me appreciate the original so much more.

[@davidstuck2866]

i used to be a mechanic. I am retired now, but I have a couple of the 3M ones that I used to use almost daily. I NEVER wore any of them completely out. I do have 1 that has about 1/8" left on it, I am sure that the 3 or 4 of them that I have will last me the rest of my life.

[@strykerentllc]

Stuff like this really puts things in perspective when it comes to 'bang for your buck'. Thanks for doing the comparison and everybody can agree that 3M Roloc Bristle Disc juice is definitely worth the squeeze. The 3M Radial Bristle Discs designed for pedestal grinders / polishers definitely are as well, albeit the prices are eye watering.

[@truckgotstuck]

Too many issues. You are using a full length new disc vs a shorter length used disc. This could be the difference between the bristle length on a narrow surface, it isn't something that can be put towards the 3M being better to control than the Amazon. If you are going to do a comparison, please compare new to new and used to used. And cavitation? That doesn't even make sense! Cavitation is a term for when air pockets develop in a water pump. It's not cavitating, it's hopping and chattering. On the cylinder head, you are using different contact points on the discs. If you are putting the bristles into an edge, they will all chatter and grab. If yo put them over an edge, they won't grab. Your testing method is just not consistent enough to establish the true differences.

[@Anonymous..VQ3.5Lg35]

I use the Milwaukee right angle with those disks at low speeds, work great, less cavitation, the green is amazing at what it will take off!

[@Anonymous..VQ3.5Lg35]

And the brush doesn’t fan out

[@hosocat1410]

So the policy in 3M marketing department is to make it inconvenient and confusing to purchase their product. Did they hire the folks from over at budlight marketing?

[@DavidWeinberg-cm9xd]

I personally mostly use 3M products, and you do get what you pay for, at least with them? I also like Osborne wire wheel products? I still will use USA manufacturers for abrasives and the like? Tried HF sandpaper, and they can't even do that well, in my opinion? Good job, keep endorsing USA anything, as far as I'm concerned?

[@MrTheHillfolk]

Was kinda surprised when I got some standard Hercules 80 grit wet, it didn't crumble. It's not labeled for wet sanding, but after that I was using it that way. Because sanding fiberglass dry really sucks. It wasn't nearly as good as 3m though.

[@1pcfred]

HF sandpaper is like pre dirtied shop rags. Want a shop rag with sand in it? Well have we got a deal for you!

[@MistakenMedia087]

Are the Amazon ones rated for that high of a speed? It looks like your over spinning them.

[@michaelblacktree]

Yeah, it looks like they're meant for a lower speed.

[@cpftank09]

Bristle discs work much better at slower speeds, especially on sealing surfaces to keep it flat. I think it’d be worth doing another video at a slower speed. It extends the life of the bristles and is a lot easier to control. I use them with my compact, low power Mac die grinder and barely even squeeze the trigger. I’ve only used the 3M ones, so I can’t comment on the Chineseium ones.

[@Eduardo_Espinoza]

18:45 Did yours came with instructions?

[@cpftank09]

@@Eduardo_Espinoza the bristle discs? No, they don’t come with instructions. But just like with any tool you use often, you learn how it operates best. The less fanning of the bristles, the better. Use minimal downward force. Basically you want the tips to contact the surface and let it do the work. Especially while using the white disc on aluminum like oil plan or timing cover sealing surfaces.

[@arnoldsmith4612]

3M products like Roto loc 2in or 3in buffing pads or bristle pads is the only stuff I use.

[@ObservationofLimits]

Back in the foundry, the bristle discs we got actually had heavy sleeves on them to keep the bristles from splaying out. But they weren't roloc, they were hard mounted to a 1/8" shaft. Also the discs were only about 1" diameter and didn't look plasticky like these.

[@PedroPlckle]

Most high quality stuff with US and European companies is made in China. But it's the licence that counts. 3M factory is in China.

[@boosted2.4_sky]

If I can find 3M and it's reasonable I will always grab those... but sometimes there are things where I just need to use it once or twice and I'm not paying $86 for it... Depends on what I'm doing... These bristle disks are great though There isn't much of a price difference in this particular product but that's not always the case....

[@scottbionicnerf8727]

Cool fact is that by default, we get to see the little M12 mini grinder put through the wringer. I used those 3M discs, both the bristle discs and the regular Scotch Bright abrasive discs with great appreciation for their abilities. I will say that the rollock disc most efficient if you keep the RPMs down. I'm not surprised to see the knockoffs not hold up to the riggers of professional use. In my past experience they weren't worth the purchase price.

[@cpftank09]

Exactly, speed kills bristle discs. Also makes it more controllable at lower speeds.

[@InchFab]

The m12 die grinder might be the most used tool in my fab shop. They're not cheap, but I just picked up another brand new one, in the box, on OfferUp for 120 bucks. If you don't have one, get one.

[@glennjames7107]

I can say that the most used tool that I own, and trust me, I have a pretty good collection, is my M12 fuel right angle die grinder. It's in my hands probably 25% of my time working, and a pretty good amount of my time playing, probably more than it should be. But it's so easy to reach and grab it. I do wish they would make a little stronger as they tend to get hot and shut down on you, if your loading it too much.

[@hvguy]

I made this same mistake on Amazon. Bought the cheap version of the white bristle discs and they were basically plastic bristles with no ceramic. The just melted and flew everywhere 😂 absolutely junk

[@enragedplantera5585]

Can you test flap wheels and non woven pads

[@glennjames7107]

Bristle discs have been around well over a decade. I remember using them regularly well over twenty years ago, roloc bristle discs. We used them for buffing of aircraft skins for corrosion removal, and preparation for repainting. They worked great on thin, delicate aluminum, but there are far better methods for cleaning things that are harder and heavier.

[@billseivers3528]

I was using the bristle discs at Boeing in the late 90's.

[@jrlaymance]

Yes, there are more efficient buff discs, there's a correct tool for every job, but when working on engines, the bristle prevents abrasive contaminants from the disc from entering the engine. The aluminum oxide rolocs are the worst thing you can use on an engine

[@omnipressant]

​@@billseivers3528 I was using them in the 90's as well in my boces auto mech classes. 😊

[@courier11sec]

I'm curious if the cheap ones have a lower intended rpm for use or if they just don't use as resilient materials as 3m does. Sometimes it pays to buy the more expensive consumables, but it doesn't matter how good a tool is if it's designed for one use case and uses for another.

[@mr.mckinnon5680]

A long time ago, probably, twenty years ago, one of my painters and I, sat down and did the math on 3M products. Vs everybody else... Because we had to. Some crooked salesman from Sherwin-Williams were trying to fill our shop with their garbage. And their whole sales pitch, of saving 6% on our materials, was absolute nonsense. We were saving way more than that, on primer alone. So we did the math. And tested the product. Sandpaper, roloc discs, adhesives. And what we concluded was. 3M, is one of the best partners you can ever have in the automotive repair industry. Their products are way higher quality. And have way more, durability and everybody else. Especially with the sand paper. I can't tell you, how many times over the last 25 years, these salesmen have come into the shop, pushing the same garbage, over and over again. And the sales pitch is always the same. Our product is one-third the cost of 3M. Yep. They're absolutely right. But by the time you get done using three times more of their product, then you would a 3M product. The cost is exactly the same. And yes, I have had, carborundum, and mirka Rolocs, come apart while I was using them. And caused me to repaint, 8 cars. Because that disk, everything in the shop, when it came off the mandrill. I let me tell you, nothing pisses off a technician more, then having to do free paint jobs, on a hood, or a roof. Because that piece of crap exploded. After that incident, I took all of that garbage, that we had in our shop. And threw it in the trash. Yes, my boss was pissed. Yet, he wasn't the one that had to clean up that mess, for free. My shop at home, only has 3M products in it. And those products, help me maintain, my Craftsman status as an auto body tech. And because of those products, I maintain a less than 1% come back rate, over the last 30 years. And I have quite literally used their products, on thousands of cars. And they have yet, to let me down. In fact, every time I have interviewed for a job. I have gotten the manager out of his seat. So I could look at the products they use. And if they aren't using 3M... I'm not working for them. You ain't turning me into a cobbler, cuz you can't afford sandpaper. And by the way, the biggest indicator, that your shop, is failing. Is when your management decides to start using inferior products. If they're attempting to cut costs, it's because, they are, tapping into their materials cost, to create the illusion of profitability. I've seen that cycle repeat at least a dozen times. And when the rest of the community finds out that, a shop has decided to use the inferior products. We all know... They're only weeks away from closing their doors. Their Titanic is sinking, and they're looking for a life raft. And by the way, I've also noticed another trend with these body shops. They're trying to do away with the commission employee. And put them on a straight hourly rate. Which is another, very good indicator, they're on their way out. Good labor ain't cheap. And cheap labor, ain't good. Especially, in the auto body industry. You get exactly what you pay for. And if your business model doesn't include pain, for good technicians, and good products. You might as well just give it up.

[@AceMon2005]

It's almost like you get what you pay for.

[@dylanbotsford2881]

In my experience with abrasives overall, cheap abrasives of any kind suck to do any real work with. They definitely might work for random stuff in the garage but if you’re doing it for a job it sure sucks changing flap disks a thousand times.

[@ChrisMiranda]

[@annettesurfer]

I use those 3M green bristle discs gently. Too fast and those bristles are forced outward. It doesn’t take much to get the job done. I switched years ago to using a green 3M bristle disc on engine mating surfaces such as a cylinder head or the block since I’ve read about Scotch-Brite Roloc disc particles causing internal engine damage. Actually they called ‘em “surface conditioning disks” but there are plenty of other surfaces I can use Rolocs without causing issues. On a similar subject, just before the pandemic, I bought a box of each color of Scotch-brite hand pads and can’t help but wonder if counterfeiters managed to perfectly fake those 3M products since the box labeling was perfect but the printing on the individual pads were barely legible, and I noticed a difference in texture. I’m not sure what happened to the easy-tear perforations but they were non-existent. Maybe 3M just made some changes.

[@1MiketheMechanic]

The 3M Roloc Bristle Discs were created over 25 years ago at the peak of GM 4.3L and 3.1L intake gasket failures in the mid to late 90's. Not sure if they were created specifically for that application but a TSB does state the exclusive use of the Bristle Discs instead of the Scotch-Brite Discs if my memory is correct. The Scotch-Brite material was getting into the engine and destroying the crankshaft and bearings.

[@juanignaciocaino]

There's no replacement for original 3M products. One often resorts to other makes not for price per se, but as you mentioned, some products are a pain in the butt to get. Being an "octopus" company that has sooo many great products hurts distribution and off the shelf availability for sure, they have so many good, excellent and irreplaceable products that even large distributors can't sink in a whackload of cash into stocking everything. IMHO the only company that's near to "par on par" with 3M when it comes to abrasives it's Norton.

[@lawhornracing6921]

From my experience with using white on both aluminum heads and steel water pump surfaces the 3m works better and lasts longer. Only downfall of 3m is they seem to be more brittle and will break off outside edge bristles if get caught on an edge. The Amazon ones are more flexible and fan out in a hurry but work okay on large flat surfaces without edges/holes

[@knocksensor3203]

3M makes good quality products.. and I am not paid by them..☺️

[@jeffreyscott2207]

3m designs their product to not remove material or as little as possible if your working on a head gasket surface or intake plenum be extremely careful because flatness it key to sealing that surface and if you remove too much material that surface will never seal properly so 3m is definitely the way to go if your a mechanic or auto technician , so have a good one

[@prophotos365]

[@stco2426]

Nice comparison and good video. Useful and quite consistent comments here on the quality, too. I've not seen these bristle brushes before and I'll be getting some. I've been impressed with some none 3M Roloc flap disks and Scotchbrite-equivalent hard-ish pads. Not experienced the grabbing on the flap and pads I have but I understand the bristle brushes you have here are not really useable as they seem to grab and overheat and aren't stiff enough. Roloc rocks! I was also impressed with the angle tool. I use air for this application and it's expensive to run compared to battery equivalents. I need to find an equivalent that's equally compact and controlable. That red thing seems good!!

[@davem4423]

Thanks for this, defo a case of buy cheap buy twice, the main reason 3m stuff is 'expensive' (a relative point) is research & development, which can be seen in the results , these chinese knock offs damage REAL companies by selling this junk that is sometimes dangerous to use especially at 20,000+ rpm steer clear of that crap....just my opinion obviously , great vid thanks again .

Happily gushing about the 3M while dissing the cheapies. Well, I guess that's expected. Anything which can make the job easier certainly grabs your affection.
