- Here is a quick introduction to ER collets and the matching collet chucks. These are incredibly useful for both tool and work holding since they hold over a wide range with a single collet.

It took several tries to pause on that quick flash of text, but worth it LOL.
Charles Blanton ah yeah thats good
Or you can just pause the video and use the < and > key to fwd or reverse the video frame by frame.
I did the same and, agree, totally worth it LOL!!!!
The irony that I just asked my coworker if they made an ER collet holder with a morse taper and sure enough this video was first on my recommended list when I got off work. Thanks!
thank you ... even watching other videos on how to make them didn't explain this well how they work ... as I have no first hand experience (all is virtual)
I'm glad it cleared it up for you. Thanks for watching!
Just an addition FYI, they make specific ER collets for taps, with a square built in. I have a set in ER32
Ooo nice! I didn't know that. I know what I'm buying with my next paycheck!
I have both er40 and er16. Every now and then the er16s are the only way to get into deep secondary pockets for complex parts on the mill. Although more costly, I’m glad I bought both.
Excellent video Stuart!
always informative, thanks stuart
You do an excellent job. Thank you for the info.
So many good ones...probably Peg :) thanks for the class- I wasn't sure but now I settled on ER40 for my new mill.
Peg is a great song. As I'm writing this, Dirty Work started playing and that's one of my favorites.
Excellent, thanks.
ER20 are a must for finer, smaller work. You'll thank me for it!
& a 4 jaw auto indexing chuck👍
An old timer taught me that on tooling without a tang drop a appropriate sized ball Bering down first to give something to push against when you try and remove it
That just changed my life lol
Love the useful information...home at last 😉
I have several ER collet chucks for various machines, love them! As for my favorite Steel Dan song, FM!
FM is one of my favorites too.
@@StuartdeHaro When that song plays it takes me back to a family reunion where all my cousins and I had a cabin known as party central
Steely Dan always takes me back to high school jazz band. My band director must have been a really big SD fan because we played a LOT of their music.
Great video. thanks for putting it together. Looking to get a milling machine very soon and was curious about collects
There are ER tapping collets and that’s a much better choice for taps. They are made to the actual shank size with a properly sized square opening at the rear. I’ve had bigger size taps slip in regular collets, then those collets may get damaged. If that happens you have to throw it away. Buy a good chuck. The cheap ones are often too off concentric. Same with collets. I’ve tested cheap ones and some are off by thousandths. Not worth it. If you find you’re breaking small mill bits, that’s often why.
good info. thanks
Hello Stuart, I went with ER-32 too as it will cover the largest range of sizes. In case you don't know, there are over-sized collets which go all the way to 26mm and still maintain their concentricity. I purchased them to hold stock in my lathe and they work well.
Predictable, but has to be Reeling in the Years. Oh and thanks for the collet info - nearly forgot.
I bought an er32 d1-4 adapter from Australia last year.
I found a pretty good deal on ER collets around here on FB Marketplace. I got full sets of ER11, ER16 & ER20's and collet chucks for each one for $30. They're really good when needing to hold something super small.
Good overview.
How about getting an ER40 holder and just buy the collets from 20 to 25 rather than a whole set. You could also just get a collet for the common end mill sizes, to save money but still have the convenience.
You may have noticed from my videos that i use a lot of ER20 collets holders so i have a full set of collets but also doubles of the common endmill sizes, in my case 6 8 10 12 mm, but for you imperialists that would be 1/4 5/16 3/8 and 1/2.
The reason i went with ER20 is because you can get the holders come with a 20mm straight shank which is the largest common R8 collet to have my version of the TTS set up.
Cousin Dupree. Always good for a laugh.
At the shop I used to work at I had an ETM ER16 collet holder with a R8 shank. It was very well made and I used it to hold small (1/64) drills and end mills. Peg or Do it again.
Both excellent song choices.
Thank you for confirming my ER40 collet purchase! (First collet set, idea from ThisOldTony)
I see you Schwartz is bigger than mine.
I love whenever items can be more universal across multiple machines. I'm trying to find the sweet spot with chuck selection and back plates, but it's a bit of a quagmire.
I'd go with ER40 to get a bit more capacity on the lathe. The mill holders get a little bulky, but it's not a deal breaker.
I'm going to buy collets very soon and I was still doubting whether to choose ER32 or ER40.
Have you ever used DA300 collets? They are amazing for little .032 drills!
I do have a little DA collet chuck, but I'm not sure which size it is. They are pretty useful. Thanks for watching!
Ever tried OZ collets? Thinking of buying a 1/" to 1" set.
I have not. I'll look them up.
I've been looking at setting up for an ER system, most people usually say they should have gone ER40.
Any negative to going ER40,
Thank you for sharing ,
the larger nut can get in the way, but not usually a problem. ER collets are addictive, and you will own many in a few years.
@@darrenfloen2693 Have to save some more pocket money ;-)
Thanks
I think the larger nut is a decent trade off for the larger capacity. I would definitely go with ER40 if I did it again today.
@@StuartdeHaro Thanks Stuart for this. I've been on the fence about which size to buy. I'm learning BG is not always your friend. Better deals can be found on Fleabay like this. www.ebay.com/itm/24Pcs-ER40-Precision-Spring-Collet-Set-Milling-Lathe-CNC-Chuck-Bit-Holder-Tool/143500157853?hash=item216946a39d:g:A9cAAOSwr0ReEpUi Thats a shitload of collets!
Where do you buy good quality ER chucks.?? I am willing to pay for US made, but none seem to be found. I have my whole shop with almost every machine able to use ER40. But I got the various Morse taper or R-8 adapters from Ebay sellers, mostly from China. I buy from US sellers, but the ER adapters are from China. H&H Industrial Products seems to import most of them, and various re-sellers distribute them. I have a few of them, right at half a thousandth runout. I am oK with half a thou, but no more than that. It is so much of a crap shoot, I started buying 2 of any one adapter, and sending back the one with the worse runout. Any good sellers of more precision ER adapters ??
Maritool sells them, although not in R8 or morse. They have straight shank tools and 40 and 50 taper tools. Check out Glacern as well. I'm not sure of the country of origin (R8's are about $100), but I have bought several things from them and they are all very nice. MSC actually carries several high quality brands and some are made in the US, but I only saw straight shanks and 40 and 50 taper tools with that search. Let me know if you find anything!
@@StuartdeHaro Thank you. I appreciate the info.
Great info. It's unfair to choose a single SD song.

Nice. I'm a big fan of Black Friday and FM, but there are a lot of great songs to choose from.
Do you work for Amazon, are you spying on my buying habits, the r8 er32 chuck should arrive this morning? Keith fenner just saw me level my new surface grinder and put up his grinder video what is next my greenhouse, spoke too soon bootstrap farmer just answered that question. Truman show is not reality. Pucker factor 11, now if only spell checker would stop changing my word choice.
Yes. You caught me. Sorry about that. BTW, some of those sites you visit are... interesting. You should really use incognito mode.
