Accupro vs ETM ER-16 collet holders
If you have any experience withe these two makes or other makes (around $225 or so per 10 piece set), I would be interested in your opinion of them.

Thanks
Ken

I use the ETM collets exclusively, not by choice, it's what's run in the shop I work at. I've got nothing bad to say about them. They run pretty trun in ETM Holders.

I hate those (Accucrap collets ) to say the least. Spend the extra cash for ETM or Ericson. Accupro wear-out to fast and do not hold a good tolerance for very long. To to mention that even if Torqued to the right spec they don't grip the tool as well as better brands. I have the ETM after wasting money on Accucrap

BTW: ETM is Iscar

Thanks for the input, while a couple of opinions does not make for a absolute, it was exactly what I was looking for. Having already ordered the ETM but saw the Accucrap for $60 lessm, was hoping I did not just throw away the cost difference. Looks like ETM should be very satisfactory.

"ETM is Iscar"... that's comforting

Thanks guys.

Ken,
I've had some issues with 'made in China' collets. For whatever reason, the top angle (the short one that seats against the angle in the nut) was not ground to a small enough diameter, thus when I clipped the collet into the nut, it would collapse a little and then I could not get the tool into the collet. I returned them and learned my lesson.

Heartech Precision is another name that I've come across. Although I have been buying from Shars Tool Co, because their prices are good, I will often bypass their catalogue merchandise, and ask for US made. They seem to be offering stuff from Heartech. I bought about 30 collet chucks (Cat40 V flange) from them for about $80 US each, which I felt was good. Apparently these are all balanced and everything, at least, they've drilled holes here and there that look like they would be for that purpose

Iscar Tooling is nicely priced for the Value you get

The ETM-ER 16 collet set came in today, In a Briney CAT-40 ER-16 holder they seem to fit perfectly, tighten up precisely using good quality vise-grips just kidding, then come out easily, that is a good start.

Made in Israel, at least for the time being, looking at the news.

Feel good as these are authentic Iscar made in Isreal. I always try to buy USA products, if the cash flow permits.
