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.

[@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.

[@Diabolos1]

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...

[@haasautomation]

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

[@BrilliantDesignOnline]

I am sure that's why all the screaming women throw themselves at you.. :-) Such a brilliant teacher...EVERY single time I learn SO much! And an attaboy to your film, graphics and editing crew.

[@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.

Thank you so much. I did mill with a Jacobs Chuck and glued the Chuck on to stop it falling out, never again. Thanks for all the tips, love you guys.

[@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.

[@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.

[@Funny-qo8gt]

The only thing i can say is awesome, i only know about collet holder before. That blow my mind now.

[@markdodge3470]

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!

[@fmh357]

That was a bit over my pay grade but I watched it trough to the end and found it worth my time. Thank you very much.

[@bradsopex]

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

[@nash0427]

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.

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.

[@CaptBeanerzzz]

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.

[@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.

[@ionutbest2005]

shrink fit + blow torch = love :)) cheap alternative to start with, before you can afford the proper device

[@robertwalker7457]

I am poor, so I use Morse taper collets on my old Chinese column type mill. It minimizes the distance the cutting edge is from the quill and maximizes clearance. It is no silk purse but a damn fine pigs ear when set up properly. Loved the the tutorial.
