Customer Reviews for VEVOR CAT40 Collet Holder ER 16/32 Collet Set, 35 PCs, SLN FMB ER16/32 APU Tool Holders Spring Steel Collet Chucks with 10 Pull Studs and 3 Wrenches, for Milling Machine Drill Presses Boring Machine

I purchased one of these sets and there was minimal runout and decent quality. After reviewing the first set I decided to purchase another.

Tool holders work great!!!!

These arrived fast and were exactly what I needed for a cnc mill I had purchased without tooling. Tapers seem well done and measure to spec. The pull studs are I believe some older HAAS style so they were a bit useless but that's a fairly minor complaint, as is the fact that ER16 collets are pretty tiny for CAT40 holders and will be of limited usefulness. I do wish there were more options to buy this set in smaller groupings. Maybe a set of 4 ER32 holders without pull studs, for example. Or a run of SLN holders. Or a couple FNB holders. I'll probably end up buying another set in the future since the price is right even with the less useful bits but it does feel wasteful having the studs and ER16 collets sitting in a and unlikely to be used.

Comes in nice plastic container for each size, not gotten around to using any except for testing the couple er32 holders I have, updates when use them some

If these work out it will be the find of the century. Good looking quality. Time will tell. I will repost an update once I have these in process.

Nice machining and very solid, no slop whatsoever.

Bought 2 sets of these, I am running on a Haas Mini mill, no vibrations at my max RPM of 6000. I have not measured for runout as most of my work is general tolerance and even a few thousandths would not matter, but they produce good dimensional accuracy and have a nice slip fit on the solid holders. With the variety of solid holders, range of collets, shell mill arbor and drill chuck this provides a nice selection for tool setups.

I bought these to mainly be used on a lesser used machine in the shop, I really didn't expect them to be anything great but for the cost I didn't figure I could go too wrong. I was actually pretty impressed by the holders, the endmill holders all had less that .0004" of runout and the er holders and collets all had less than .0005" of run out. The only holder I was not impressed with was the keyless chuck, it has up to .010" of runout at certain diameters when checked with gauge pins. This entire set cost less than a name brand set of just the collets so overall it is a great value and I would recommend it.

Arrived in good condition, seemed like a really fair price for all that I received. I particularly like how each is individually contained in a plastic case, I intend to keep them in those. I'm not experienced in machining, but I'm happy with the purchase.

Good value, they work as they should.
