VEVOR Collet Set, 25pcs ER16/ER32, Collet Chuck Tool Holder, 1/16''-3/4" By 16th and 32nd Industrial Grade Accurate for CNC Lathe

Absolutely awesome. Use them all the time. Very high quality.

I hate to give the product a bad review, because what I received was actually pretty decent, especially at the price point. The threads on the ER collects are super smooth, but some of the internal threads had some minor issues. They're not super beefy compared to my other tool holders though (see image) , but this can be a good thing where clearance is an issue. So why the bad review? First, what you see in their picture isn't exactly what you get (that's not really a surprise though). For me, this is a nonissue, but it's an incorrect representation. Another small annoyance is that you get 13 tool holders and 10 pull studs. I already had some extras laying around, but it's still annoying. My main issue is with VEVOR. My face mill, inserts, and wrench were missing from my package. When I got a hold of customer service they said to show them which part was missing and they would get it out to me. Great, 5 star service, I'll start using everything else in the meantime. A week of back and forth goes by, the last thing I heard is: "we're sending your request off to the technical expert." That was a few weeks ago, I've made attempts to follow up, but have received nothing back. I'm not super upset, I'm happy with the tools that I received, but I'm disappointed that I didn't get everything I expected. Update: Reduced to 1 star. Followed up with the company again. They said that the face mill isn't included despite it saying that it is three times in the description. Garbage service, BBB reviews confirm it. If you're going to order from them I suggest ordering through Amazon so you don't have to deal with VEVOR if you have an issue.

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.

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.

I am happy with the quality
