- Whether you’re a beginning or advanced machinist, you’ve probably wondered more than once if you’re using the correct collet. With so many to choose from - and often confusing sizes on the collets - it’s hard to know if you’re using the right one. In this valuable Tip of the Day, Mark looks at each type of collet, and explains how and when to use each one.

Wow, learned more in 20 minutes here than in hours in the classroom. Great job guys!
Kent VanderVelden
You said it. Very interesting and useful video.
Very well said!!! I agree!
Kent VanderVelden idk my teacher breaks it down well I need a physical teacher hands on he breaks the video down
The best video what i see ever
perhaps pay attention in class once
I have no idea how I found my way to this particular corner of the internet but man, this is how educational videos on youtube should be done! Even if I have no use for the information in it that doesn't detract from the face it's fantastically presented and clear as glass. Top job!
i used collets for a looong time but I learned a lot in a few minutes, its like a deaf person hearing music for the first time, thanks a lot.
Mark has done it again! So much GREAT information. Thanks Mark.
This is precisely the kind of content we love from you guys. Very well done and useful information.
I love this channel. Thanks for all the wonderful, useful information. Merry Christmas.
Thank you. Centering tools with ultimate holding power. Satisfying machinist ocd.
This is an amazing service you guys provide with passion.
Not everyone gets to hang out with old school machinists. Thanks again
Ultimate holding power sure won’t come from ER collets.
@Maciej Jan Długosz Not true; standard shrink fit holders are much stronger than ER collets, but are absolutely not the option with the strongest gripping force. Heavy-wall shrink holders are a big step up, but for “ultimate holding power,” there needs to be a mechanical connection like a “Safe Lock” groove in a shrink holder or a Weldon shank. Even a milling chuck can offer more grip force than standard profile shrink fit holders.
Not a darn thing wrong with ER collet chucks; every shop should have some in my opinion, but they’re not the best option for any one thing.
@Maciej Jan Długosz collets can achieve more clamping than shrink fit.
Shrink fit only allows for a few thousands.
Thus limiting actual holding force.
Collets use a screw and wedge combination to achieve ultimate clamping force, do the math.
@Maciej Jan Długosz actually.
If you couple shrink fit tool holders with loctite 680, no amount of physical force will move the tool providing the tool shank doesn't exceed 450 degrees Fahrenheit to release the adhesive.
Thanks for this. What a great video explaining all the collets. TH-cam needs more great videos like this.
Great video, thank you! I absolutely love your thoughtful, no compromise approach, how you consider every small detail.👍❤️
new into cnc you answered every single question i had thank you!
Fantastic video, great explanation and also some very hands-on shop advise, like rusted collets!
Also for me it had a great balance between some jokes to keep it light and interesting, without overdoing it.
GREAT VIDEO! Please do more of these educational videos, good to learn from real experts!
Mark, this was an outstandingly informative and well-produced video. Good job!
I really appreciate you guys naming the products that you're using
Awesome to see the video! We were lucky enough to meet Mark and see him working on this video when we did the HAAS factory tour recently. Keep up the great work!
Gavin Bath exactly what I wanted to say
Mark, thanks for schooling me. Extremely valuable and appreciated with your (and your T2 cyborg unit) classic style.
That was one hell of a clarifying video ! Don't you guys ever get tired doing that kinda stuff.
I am going to make this required viewing for each of the operators here at my shop. Great information. You even taught me a thing or two!
Joseph Elwell - Thanks for comment. We loved making this video! It was fun, with all the props. It went longer than we’d have liked, but what can you do, there was a ton of things to talk about. Thanks again. - Mark, Haas Tip-of-the-day
Wow thank you so much. I definitely didn't know anything about ER collets as I thought I knew. Great work!!
This was so informative. Thank you for taking the time to produce this TH-cam.
Mark, you are brilliant!! I wish I had you as a mentor.
Good explanation.
Really easy to understand what you are speaking (good and clear English).
Many thanks for sharing.
yes! I'm studying English and Haas's videos helping me with it
Thanks Mark for such an usefull piece of information !!!!! KEEP POSTING SUCH VIDEOS
GREAT JOB Guyzz
Love those video from Haas, valuable videos for all machinist.
So much to learn... I'll have to watch this several times.
REALLY well done, so many little tricks to saving your tooling and making it run more accurately. I can't say how many times I have seen folks at the machining school i went to break all those rules and then some... makes me cringe thinking about it!
when you don't have the right collet, use a smaller one and a tap with the --hammer-- screwdriver on the end of the tool will do, right?
These videos are superb. Well done and thank you.
Good on you for the evolution of your lighting setup for these videos.
Thank you so much HAAS for those great infos. I learned alot. Maybe one day I will have my own from you guys :)
YESSSS!!! More of this! More of the fundamentals PLEASE!
I’ve been machining for 8 years now. Never ran a Haas, but man…I absolutely love your videos. Such high quality, and taught very well. Please keep up the good work!
great info. videos are always well formatted and presentation is great too. thank you!
damn impressive Haas.. love your videos.. to the point and relevant and in a mannor i can comprihend from a non CNC owner.
and it was a huge joy to follow Haas in 2018 in F1.. great team, and Gunther Steiner for prez in Denmark.
This is right up there with the TCP video. Top notch.
Great video. I don’t have a HAAS but this video will help out any machinist.
I didn't know about the seal caps. I've got to get some of those! Not as much for the TSC, but to stop the cast iron building up and setting up where it becomes a pain to clean out.
awsome video. im just learning and this the best video ive seen.
This is an outstanding video. I'm only a "hobbyist" but I feel a lot more knowledgeable than I did twenty minutes ago and I've already watched four other videos supposedly about this topic!
PS. I love the vending machine, brilliant.
This was very informative for someone new to ER collets. Thank you.
Awesome .... Thanks for the explanation and it's wonderful
Thanks Mark for you time.
Great video and information Mark - thank you !
Excellent video. All the important information one needs!
Great information presented exceptional well, thank you very much.
I have decided this was the best video in the history of the universe. HOW DID YOU DO THAT THING LIKE IDENTICAL TWINS AT 8 MINUTES??!
Thanks Jeff. I sent your comment on to the Editor who produced this video, Tyler. He said that next time there would be 4 Marks, and would say nothing further. Thanks for the comment! - Mark, Haas Tip-of-the-day
Just getting into machining, learned a lot from this video. Thanks
Incredible info. Loved it. Thanks for sharing
It is hard to convey how much enthusiasm I have for those videos. You guys are an institution and your educational model smashes other more classical approaches
Great video, very informative, more like this is needed, Thank you
Great video, very informative! The part with the PIN cracked me up. :D
top secret :-)
I've never seen a CNC irl, but I watched this entire video because it's so well done and interesting.
Very informative and well presented - thanks.
This was a fantastic instructional video! Thanks!
so nice information, well done 👍
Thank you for the video. I'm new to milling and I didn't even know these existed. I have a ER40 setup for my milling machine and I will be ordering a bearing style nut for my R8-ER40 adapter.
Many thanks, very helpful information and useful hints
Great very informative video .Well presented ,Thanks
Excellent information, thanks !
great video , with some great humorous touches
Fantastic video and instructor!!!
this is nuts...great job mark 🤪
Amazing
Every video which you share hare does enhance my knowledge.
God bless Hass👍👌🤞
Great information. Thank you for sharing
Thank you for this very imformative video!
11:09 *Ａ ＧＯＯＤ ＮＵＴ*
Your videos helped so much in my life experience sir
That was great, thanks. Around the world of ER collets in less than 20 minutes.
Great Haas Team. Thanks a lot.
Man - this helped so much - tank you!
Amazing informative video!
EXCELLENT VIDEO
brilliant as always
Very informative, Thanks!
Very interesting and learn lots of skills thank you so much sir..
Good comprehensive video. The only thing he maybe should have mentioned was regarding the collet nut thread fit.
This has to be close fitting for good accuracy. Worn or loose thread fit is a no no.
thanks for this video, so helpful!
Great video with a lot of useful information. What left me empty though was there really wasn't an explanation to WHY you don't put a larger tool in a collet than what it is made for other than you will damage it. Some people need a graphic or something to see why to really understand it and/or believe it. Thanks for all the great work you do.
Nice clear useful advice
All i want to know is how you survived getting run over by that forklift at 7:10 ?
It was his third clone
@@NeilAbalone Hahahah, good one :)
Interesting even that the forklifts and pedestrians share the same path - would never be allowed where I work.
He called for it to take him back to the machine room. Used the forkLyft app on his phone.
@@Phantomthecat lol my dude u union?
Muy buen video, muchas gracias
Quality content, great!
We have 2 kinds of TSC ER collets, the ones with the rubber seals as showed here and some without rubber seals where the slots are shorter. I've found that the ones with rubber seals have to be on size or the tool is likely to slip. Also the rubber seals will eventually blow out.
excellent video... thank you
Waaw, this was a great one !!
Ha! I thought the same thing about the forklift!!!!! OSH. But I really wanted to thank you for a most excellent video. Thanks
Excellent , very very useful thanks for teaching😉😉😉
Awesome info!
Sure wish I had one of those tool dispensers in my garage! :)
Airgas had those in a shipyard I worked at filled with small welding consumables and PPE.
Great, great video..great information...tks..! :)
great video
Good job on the video :D
Thank you so much.
Love these videos. Could you please tell me which Castrol Rustilo you use? There seem to be about 20 types...
Great one...
8:12 is comedy gold. Fun fact "Flush Nuts" was my nickname in highschool
Great Job Mark and Haas on this video! I’d like to point out one thing you didn’t touch on, that I’ve found employees do in the past, especially when using these collets for holding endmills. Although you mentioned it is important to have clean surfaces on the holder and collets, you did not touch on the importance of breaking down the collet setup when switching out tools in the holders when tools become dull or time to replace. Chips, coolant residue, and debris gather in the collet slots during machining operations. And in changing out a tool when you loosen the collet, this residue can work its way from the slots to in between the collet and holder surfaces. Now when you clamp down on the new tool, you are smashing all of that residue BETWEEN those two surfaces, along with the suraces of the collet and cap itself where those two surfaces come in contact. I know it may seem simple common sense to always break down the collet from the cap and remove it from the holder, and clean all surfaces when changing out a tool. However you’d be surprised how often this happens if employees are not instructed in the importance of doing so.Thanks so much for these videos. They are a great teaching tool.

Donnie - Great point. Thanks for commenting. - Mark, Haas Tip-of-the-day
We use chip chasers to clean out the veins of collets. Works well. The chaser is spring steel, about the thickness of metal banding, maybe a tad thinner.
Use the 6" steel rule in your overalls pocket. I always have 0-1 mic, needle file & marker pen in breast pocket. Then use airline and corner of overalls to clean. 👍
Regarding choosing right collet size (at 7:15). I had the following experience:
I had big tool runout when used 1/8 inch tool shaft with 1/8 inch collet (ER-11). When replaced the collet to 3.5mm the tool runout has disappeared.
Therefore I would choose collet of some bigger size than tool shaft.
Sounds like a damaged or dodgy from new 1/8" collet to me. It would be worth checking the TIR with a measuring pin and discarding it if it's no good.
1 Don't bother buying cheap no brand collets , they're.... cheap! I found 'F' brand are good think it's fahron he showed 1 in the video
2 the 0.5mm collets are very useful for small/precision work.
Very informative
sir thank's for video and knowledge u explain nice
@haas automation. What is the force limit on the vise included with the convenience package. I Can't find that spec anywhere. Can you use it to put the full 100lbs on the collet nut
