Customer Reviews for VEVOR Collet Chuck, CAT40 ER16, 5pcs Tool Holder Assembly with Pull Stud Wrench, 2.75'' Gage Length 15000-20000RPM for CNC Lathe

My experience with these Collets are extremely positive they fit perfectly and our machine excellent.

I’ve seen this question asked a lot. So here’s the answer. I closed the jaws all the way and they fully close. It held a .010 gage pin just fine. Runout with a .200 pin was .001 TIR, and with a .5 pin it read .0055 TIR. The retention knob fit a haas VF2 with no problems. Rotating by hand to clamp down provides plenty of holding power for smaller drills, but I would use the spammer for anything over 5/16. Bearings feel decent, not rough. At this price, buy a couple.

Works fine in my haas mini mill. Good for the price.

I was super impressed by these toolholders. An amazing balance of quality, standard tool selections and price. The finish on these is amazing, and everything fits together very well.Unfortunately, I need to return them. CAT40 was an optional upgrade for my machine and the seller I bought it from was misinformed on the size. Really wishing there was an equivalent package for BT40, - this seller would have my money instantly. Unfortunately, the selection for BT40 tool holders is challenging at best.I'd heartily recommend these to anyone who has a CAT40 machine with no regrets.

Really recommend these. We were able to implement standard tooling buy buying sets of these holders. The er16 holders by orangeA are good too.

A good starter selection of collets for my mill.

Great quality, well balanced, will buy again!

Small Prototyping Machinist here, ordered these 5 ER16s because i needed to be able to set more tooling up without having the remove and replace tooling for different jobs. These came packaged in the twist and lock containers made for CAT40 holders and were enveloped in a thick plastic with oil to keep them from rusting, very content with the quality of the holders themselves, fit my ER16 collets without issue and ran all five of them up to 4000 RPM (machine max) without any issue. Will be ordering more in the future.
