Tool Holder Essentials - Every Machinist Needs to Watch This - Haas Automation Tip of the Day

[@morningstarx5340]

I hope people give them the credit they deserve for making these informational videos. They are so damn valuable. Not just for beginners but for anybody that is in the machining world.

[@SkyVega-lp7rq]

I'm a first year Tool and Die apprentice and have found a ton of great content on KZbin but HAAS goes above and beyond giving incredibly useful information that everyone in the business should know.

[@HaloGamer401]

As a College student with 2 Haas Mini Mills at his disposal, thank you Haas (Mark you are my hero!) for this content. It’s amazing how much there is to learn about this field and while I’m doing my absolute best to master it all before I graduate, the reinforcement of these videos is a tremendous help. This is what sells machines.

[@haasautomation]

HaloGamer401 - Perfect! We are glad to hear these are useful. If, in your studies, you run across a topic that you think really deserves its own video, let us know at [e-mail]. Thanks for the comment. - Mark, Haas Tip-of-the-day

This video is essential viewing to any machinist. In fact this whole series of videos is. But this one especially.

[@Duschbag]

Wanna bet...? I'm a Distributor who sells tool holders from PARLEC and Techniks. When I strongly recommended that a customers Machinists all watch this video... I was told "All our guys already know all that stuff" I knew the customer well enough to LAUGH OUT LOUD and say: NO... They DON'T. I have seen your Guys to stupid shit with the toolholers and Collets for years. Toolholders and Collets do NOT last forever. They wear and need to be replaced with new tools. You have many that need to be replaced right now and I can prove it..! But, in my business, the customer is always right. Even when they're not.

I come from Germany, for 25 years I have created fixtures with 3-axis milling machines from DMG and Kunzmann. I use inexpensive standard Weldon Tool Holder (SK40) with side screw connection and ER Tool Holder because the milling process is below 10,000 rpm and the accuracy is sufficient. I really like Mark Terryberry's lectures because I refresh my knowledge and learn new things. Thanks a lot for this...

Great comments Pascal. A standard Weldon Holder is fine, even ideal, for a lot of applications, especially when running at lower rpm. Thanks for posting. - Mark, Haas Tip-of-the-day

I'm attending the College of Western Idaho Machine Tool Program. Our instructors thankfully have your Haas videos as a part of our sylibus. They are great and I enjoy watching them.

[@james_the_blue4426]

We especialy use shrink fit chucks from Haimer for our milling operations, but with all the trochoidal milling strategies, I often switch to milling chucks. The high force chucks are much chunkier so they can absorb more vibrations and I can nearly double my tool life. We don't use drill chucks at all, we use the ER32 System for all "normal" drilling operations. The ER is also good for PH HORN slotting tools and Iscar Multimaster tools for example. We use the hydraulic chucks especially for drilling with solid carbide and PH HORN gun drills. It's much easier because of the internal coolant, so you don't have to use a sealed ER collet and also better absorbtion than the shrink fit chucks. As usual a great video from you guys. I often use the Tip of the Day videos for our apprentices because it's very good contant for begginers AND pros. Keep going, great job and geetings from Germany ✌

[@haasautomation]

Marcel - It sounds like you have a terrific system for toolholders, using the right holders for the application. Thanks for posting. - Mark, Haas Tip-of-the-day

[@yoimalex]

How do you like the Iscar multimaster tooling? We have been using the system for a while now with mixed results. Using Er style holders similar to your setup probably

[@james_the_blue4426]

@@yoimalex we use the Multimaster toolsystem for chamfering operations were we need that extra bit of length to get to the contour, especially in combination with five axis vises. We also use the ballnose inserts and the inserts for outer radius milling. I realy like the tool length, just imagine you would use a five axis vise for clamping and than you use a big bulky chuck with some short tools. There is where the multimaster makes money. And on top of that comes the simple tip change and the big variety of inserts.

[@OddJobEntertainment]

I'm a mechanical engineering student and I've been watching these videos to get insight on how the machinists have to work around their machines and materials. This series has been extremely helpful in improving my garage hobbies and my understanding of the topics. It reinforces the idea that the machinists have a wealth of knowledge that I'd be wise to pull from but it also breaks things down in such a way that I understand better without having that knowledge myself. For example, if I talked to the machinists at work and I know that we don't have the high clearance shrink fit holders, I might change the design to avoid needing it. Then I'd talk to the machinist again and see if there's any other pain points I can rework to make us both more profitable.

[@SophiepTran]

Great info! Learned so much about tooling. A while ago we had issues with roughers in 1" shrink fit holders we've been using for years, pull out. Tool and holder tolerances were on spec and nothing has changed with the tool path or machines. After doing testing and research it turns out that we weren't keeping track of cycles and that these tools have a cycle life suggested by the manufacturers. Having heat cycled them for years, they slightly lost their malleability and grip strength. Maybe those that work in places that cycle their heat shrink holders a lot should keep track of the number of heat cycles each holder has gone through. Just a thought.

[@jameslezak8179]

Best explanation and demo of tool holders I've seen. I've worked in large and small shops for over 50 years, manual lathes and mills, and NC lathes last 25years. Not being a NC mill guy, I've seen some of these but never the physics. I'm retired now, have a home shop, with manual machines. I still smell like "sultex" most of the time. Lol.

A minor point worth mentioning in an otherwise superb video. Mark says about the 5:00 minute mark that twist drills are straight, but actually jobber length high speed drills taper a couple of thousandths smaller at the shank than the nominal size. He should mention that the shanks are softer as well, that is why they get scarred up when they slip (and distort of someone puts a drill in an end mill holder.) Your videos are a great source of information, please keep them coming!

I am just getting started in machining with a garage shop making racing components, and have been researching the best tools and tool holders to get when starting out. Since I will be doing a fair mix of milling and drilling, with no need for super tight tolerances, I had settled on an ER32 system to start. Having watched this video, I feel more confident in my decision and have a good idea on what to get next to increase my capability. This has been really informative!

[@georgedennison3338]

Definitely get a pair of ER32 collet blocks, (square and hex). I got a pair when I I got an ER32 set. Even though I don't have my machine set up so I can use the ER32's, I've found a number of uses for the blocks. They made my life much easier after I put together a sorted box of shims, (½x½" each), then discover what a pain in the ass trying to get a 0.001" shim out of a ~1x1" section! i tried everything then remembered I got a container of 1/16 x 1/16 x ½" neodymium magnets, along with a bunch of other neodym's, from a retiring machinist last year. Figured I'd never use them. I grabbed a 4" piece of 1/8" PCV welding rod, and thought I'd end drill it, and insert the tiny magnet, to make a strong enough, but not a grab every friggin' thing magnet stick. Then I got to thinking about end drilling the PVC! Put it in a 2mm collet, then in the square block, and did it in my drill press like I'd done it for 20 years. It was so easy, I made a half dozen more, and put them in my 'microscopic' machine screw boxes. After a couple of uses, I realized I had to paint the useful end red because it's so hard to see the timy little magnet! What kinda racing you into? You making parts for your own car, or for the market? Good luck.. GeoD

ER COLLET Milling Holders is still the staple in come of tool holders man, classic!

[@gangleweed]

This has to be one of the very best videos on tool retention that you can tap into. I'm a golden oldie and in my day we used the Autolock chucks with screwed shank tooling......now very hard to find anywhere.....for ultimate tool retention and runout. That design is a hard act to follow as it fulfills all the necessary desires of the aforementioned criteria in the video with rotating tools apart from drill chucks where the keyless chuck reigns supreme. My personal present like is the ER system but with cheap collets it's only as good as the price you pay. A lot has to do with the class of work you're involved in. Backyard engineering is the bread basket of the cheap Chinese tool system suppliers.....long may they live etc. I've often wondered, for the bottom end of the milling cutter users, how a milling cutter with a short Morse taper shank instead of a parallel one would perform as it's practically like a shrink fit system without the heat/cooling aspect for insertion/removal etc.......not practical in the real World as the knock in effect could/would damage the cutter. For me it's the ER system due to the massive availability of cost effective tooling and if I have a runout problem with a cheap collet(s) it translates to just a bigger cutter diam as it rotates.....what's in a few dozen microns of extra cutter diam anyway.....one pass will give your the cutter size you're working with, so cutter diams become arbitrary anyway if you know what you are working with. The combination of cheap chucks and cheap collets does leave the choice wide open, but selective testing and grading can cure many evils. BTW.....I toyed with the idea of having an ER collet and modifying a cutter to have a groove near the top end of the shank to fit a retaining ring so that the cutter would not need humungous tightening force to prevent it from pulling down.......thinking, thinking etc.

[@luisgamez9941]

You provide awesome content. What might take years of experience to figure out what holders to use, you showed us in 30 minutes.

Very nice and informative video. We've got all types of tool holders you showed in our shop, but we had a vibration issue with deep (10D ) tool and that wouldn't go, the surface quality was terrible and I was searching for a solution. Then we had a 3axis DMG machine. With the Regofix PowrGrip, we eliminated that vibration. We'd also looked at Tribos but that just does not have the grip of RegFix. The system worked so well that our new 5axis DMG with 60 tools is almost completely loaded with RegoFix tool holding. The ER system is used for drills only.

[@GeorgeGeorge-yb2sz]

Good information, especially for someone like myself to learn about the different systems used in machining. I have discovered that there are a lot of different types of collets depending on what you are holding. There are tool holder collets like most of the collets in this video. There are work holding collets like the 5C that are designed to hold a work piece instead of a tool. Then the ER collets that will hold both work pieces and tools. What you didn't mention was the R8 collets. Probably the most common collet system on small mills and there are a lot of them out here now. As I said, good information and I am looking forward to more from the series on the website.

[@DustinMaki1]

If a new shop went with REGOFIX POWRGRIP right away, what other toolholders might they still need? Would it ever make sense to have a powergrip holder for each common drill size W/WO ATC? Can powergrip holders be damaged, or are they fairly idiotproof?

[@charmzee8749]

Nice addition of the metric system. Europe appreciates you. Also great pointers i learned in 4 years of machining. While boring never EVER turn the bore dial backwards unless you really screw it up, back it up by 0.1mm and feed about 0.01 mm to 0.02mm on the dial until you reach again the diameter you were on (Using an URMA boring tool with a dial for precision diameters). Also if the shank of your drill look like your brand new tires, bring them to a lathe and get em' cleaned. Also you must and i can't stress this enough MUST use 3 passes for a 0.01mm to 0.02mm tolerance pocket or contour >Roughing>Semi-finish with a new mill (leave 0.04-0.05mm)>Finish. Pre-drilling is important for drills under 13 mm and a depth of more than 60mm, and it's absolutley necessary for drills under 7mm at the depth of more than 50mm . Also when reaming closed holes, leave 2-3mm from the end and finish manually and drill the hole 0.2-0.3 mm smaller than the reamer for softer steels and 0.2mm for harder ones and for plastics and aluminum you can safely use 0.3mm smaller drill diameters.

[@deans5479]

Love the video. I drool at heat shrink. Storage of collets:, one lazy machinist can make every collet you have junk by not cleaning and oiling these collets AFTER use. I confronted the coworker with a handful of rusty collets and he thought his time was to VALUBLE to be fiddling with collets so he just put stuff away wet into wood holding blocks...Management did nothing so I quit and got a better job down the street. For a 1 man shop that needs to hold a spotting drill in a extended Weldon holder a brass plug that has the same radius as the tool bit works great under the set screw but the end of the brass plug must fit the radius of the spotting drill and be as large as the root diameter of the thread. I have ran finishing endmills without a flat with a brass plug. Sometimes the plug will split in 2 but I never had a failure. Brass plugs take time to make. My favorite is the compression holders. Since nothing is perfect the sleeves have a little runout usually .0001-.0002 and one can rotate the sleeve in the holder tighten indicate then loosen turn 1/2 tighten indicate enough you can use that to get a endmill to run with minimal runout. But why bother if you heat shrink? As much as I want one I will never get one approved.

We switched to mostly hydraulic tool holders and they are AMAZING. The Schunk holders aren't that expensive and they are amazing. We quadrupled our IPM on every material we machine and the difference in tool life is insane. I used a Guhring RF100 Diver in Schunk holder for making about 30 1018 soft jaw blanks, milled about 8 pairs of those soft jaws, and then ran that same endmill on 300 parts that were also 1018 steel all at 200 IPM + and the endmill still looked brand new. I use a hydraulic holder whenever I possibly can now.

@@railgap prior to defining the inch precisely as 2.54mm it was the length of 3 barleycorn's. As a result all countries using inches had them at different lengths. All.

I have a metal lathe, but I wouldn't call myself a machinist. I'm not very good. I work on and restore/refurbish vintage machinery and sometimes need to make a small part. This video came up in my feed; very interesting content. My main drill press with a Rohm keyless chuck has a runout somewhere near a tenth an inch out. The needle on my Starrett tenth indicator hardly moves. IMHE, this is extraordinary for a drill press. The machine is a Delta DP-220 originally built in 1941. I get a lot of DP-220 coming through the shop and over time selected the better parts for my own DP-220: bearings, spindles, pulleys, blah, blah, blah. The parts were made between 1939-1955. Modern Baldor motor. Ended up with runout I can't even measure. I'm tap dancing daily in total joy. Seeing this video, a tenth runout seems to be the standard in precision machining. Can't believe a drill press is doing it.

[@ydna]

here's a new one...try using a 3/8" endmill inside a weldon holder with a 1/2" bore...then after breaking 3 endmills and ruining a couple workpieces, we eventually figured it out. But he still asked "well how was I supposed to know???"

[@Alex-rf1md]

someone at my workplace once mounted a 5/16th(around 7.9mm) tool in a 8mm sleeve in a hydraulic chuck... didn't ended well...

[@gearloose703]

I wonder how chinese carbide would fare in a hydraulic chuck, they are sort of precise but the not necessary any exact size but often down several hundreds of millimeter.

[@ydna]

yeah that's a downside with hydraulic holders that wasn't mentioned in the video... they can and do fail sometimes (like anything) and there's also a bit of learning curve for working with them (again like anything I suppose). The powrgrip system was intended to fix that, and it's definitely more reliable.

[@mischiefmachinellc]

Shunk Tendo E compact are fantastic. The day i was introduced to them was the last day i put an end mill in anything but a Hydraulic holder.

[@texastad1989]

Have one, wish I had more. I actually use it for my finishing tools and rough with ER32 or Endmill holder, reason is I get the best finish with it. Now if I had more.. different story :)

[@haasautomation]

Mischief Machine - The hydraulics I have on the table at 28:55 are Shunk Tendos. Nice holders. I like them because of how short they are able to keep the units, with the hydraulic channels run deep in the holder, inside the taper. The hydraulic holder we cut in half was a more typical style, but showed how the holders work well. Thanks for commenting. - Mark, Haas Tip-of-the-day

[@EmperorDevilhunter]

Great video. A few more tips: You can use the torch to heat and load and unload the shrink fit toolholders., so a small shop can avoid having to buy the induction machine (or toaster, as we call it at work). Put some grease on the threads and nut taper of the ER collet holders if you don't have the low friction nuts. This will improve both holding force and runout. Speaking about ER and runout, it can be adjusted once set up. Some people tap the nut, although there are special tools for it. Try to torque the nut with two handed tools to apply just torque and not lateral force. And last: don't use that Haimer balancer with wet toolholders, believe me.

[@georgedennison3338]

Two handed tools? Do they put one hand one each side of the collet nut? I've had a collet nut wrench on my To Buy list, but my machine set up was waylaided, so the urgency disappeared. Even if you used a two hander, wouldn't you need to be careful not to push away from your body excessively? Seems like a deep well socket for the collet nut might be best... ever seen one? hmmm. might have to fabri-cobble one. LOL

[@EmperorDevilhunter]

@@georgedennison3338 This is an example of the two handed Haimer torque wrench: www.amazon.com/Haimer-84-600-00-AK-Inserts-Standard-ER-Chucks/dp/B012AI5NXS A deep socket with a T wrench may work too

[@iainwalker8701]

If you normally run between 1-20 offs, most universal holder I would say is ER collets. I have been running ER32 collets for many years "torqueing" with a small hammer and never have pull out issues. Maybe there is minute runout, but I frequently machine parts to within .0025" limits, up to 5000 rpm with no noticeable imbalance. Mainly use them for endmills (finishing + roughing) and almost all drills under .787". For 20mm-25mm-32mm-40mm-50mm and smaller ER extension collets or other tooling I normally use sidelock holders. ER chucks are capable of taking a lot of abuse, if you forget to stick the tool out far enough and the holder rubs the workpiece - replace the collet nut and sometimes the collet. The holder itself is protected from damage. also ran 100s of holes with tapping ER collets, again without issue. Unless you machine a very large quantity of identical parts, I have never seen the advantage of most fancier style of holders, if you are making 100+ off quantities I think you would undoubtedly notice the difference, but for job shops ER collets is more than capable.

[@willysnowman]

Very good presentation! Thanks! 👍

[@Changtent]

Overall fabulously interesting, thanks. On hydraulic tool holders, I would be concerned about bleed-down time. I have never seen a hydraulic locking system that would hold its grip indefinitely. For example, hydraulic park brake systems are sometimes used on heavy industrial vehicles only for very temporary parking. They would never be trusted to park a vehicle overnight without blocking the wheels. So do hydraulic tool holders have a cycle time to be re-tightened or released?

Excellent video. I have to admit two things. Never used a milling chuck (probably never will!). Ran an end mill in a Jacobs chuck when I was in a rush. Pulled out immediately - the job took longer.

[@leensteed7861]

My only problem with tool holding was with the HAAS endmill chucks. The chuck couldn't handle a 1 inch sandvik R.390 cutter which it broke the inserts on within 3 inches of cutting. We then tried it with a high quality 1/2 inch Harvie TE solid carbide. It broke the cutter almost instantly. All the operations where the HAAS milling chucks failed ran smooth as silk with simple, weldon endmill holders. We returned the chucks to our dealer, Thomas Skinner in Canada and they claimed the chucks were "fine". They are not "fine". They are useless for milling. The dealer is fighting us on the refund despite the fact we have bought 3 brand new HAAS machines from that dealer yet they argue over $800. I have video of the cutters working with both the faulty milling chucks and also how they literally purr through steel in the weldon holders. I will be happy to post a video on KZbin showing their poor performance if anyone has doubts. Regardless of the tools performance I find the non existent customer service to be deplorable.

[@mannycalavera121]

One thing you didn't mentioned is the fantastic properties weldons have for dampening or disrupting resonance in cut. Because of the slightly offset tool this has similar effects of a variable flute and disrupts any possible buildup of resonance aka chatter. Quite often when tooling manufacturers do side by side tool comparisons they leave out the weldon, purely because when they include them they offer the same if not better dampening (wrong word technically, resonance disruption?) than holders that cost 10x+ more. Search it on KZbin, plenty of good examples. Also modern weldon are offset ground to compensate for the runout that used to be an issue. You still get run out but only within the tolerance of the shank grind.

[@nbowling10trio]

Spot drill and common drill sizes are fine in endmill holders when you put your flat on it, hit it on a buffer and break the sharp edge around the flat and it will slide in and out easily. I've seen the hydraulic toolholders extend tool life personally when milling cobalt chrome with coated carbide. The holder will pay for itself over time only having .0002 runout.

[@pappaflammyboi5799]

.0002 mil is 50.8 nm. You sure about that?😳I would think some light side forces would result in greater than 50 nm deflections whilst cutting, making the runout a moot measurement.
