Customer Reviews for VEVOR 4Pcs CAT40 Tool Holder ER16 Collet Chuck Set length 100mm Chuck Tool Holder Set Mill Holder for CNC Engraving Machine Milling Lathe(4Pcs CAT40 ER16 100mm)

These are a good addition to my tooling for my Haas machines, The price was right and they were delivered fast. I will purchase again.

JUST AS ADVERTISED. GOOD SELLER

I use it in my mini lathe and mini mill and have been able to utilize much more space on the lathe and the mill has a lot more z space than with the jacobs chuck for sure.

Using this tool holder so I don't have to have so many CAT50 tool holders. Also bought a set of ER 40 collets in 1/8 so changing end Mills is a breeze. Beautifully machined tool holder and collet nut. Works great!

Performs exactly as I'd hoped. It may or may not be aerospace grade, but it's more than good enough for my maintenance shop. No problems.

I purchased this set for home use on a new lathe. I took a stab at this set since it had many more sizes than other sets. When it arrived, I found each piece to be shrink wrapped in its own marked container. The size is on each container and also laser etched into the face of each collet. I found no grit, no burrs or machine mistakes, so I was impressed. The finish on each is polished and there were no sharp edges, that was even better! Overall, I wasn't sure what I was going to really get for this price, but I've used 3 already and can't complain. In fact, I don't usually write reviews, but, because I found reviews helpful in making decisions on unknowns or new tools, I felt this set of collets was worthy of posting as they appear to be better quality at a very reasonable price.

Seemed to be excellent quality, great price

Worth every dollar. These are excellent collets. We use these in our aerospace tooling job shop.

I have been using these on my Atlas 12” lathe mostly with my milling attachment. So far they have performed well holding HSS drill bits and end mills. I can’t attest to the run out of every single Collet but of the ten or so that I have used, I have gotten good results (indicated one of them with an end mill can’t remember what I got but it was acceptable for a DIYer). I gave four stars because one time I used one of these collets (maybe the 3/8”) to hold a piece of aluminum while I drilled and tapped the end and after removing the work I was disappointed to see that the collet had formed a ring a couple thou deep in my part. There was obviously a bur on the collet where the face meets the bore. Now this is easily remedied and I cant complain because the runout appears to be good or atleast as good as my collet chuck can provide but a little frustrating when my part was already turned down to final OD. I would recommend especially at the price!

The product was as advertised, very pleased with the quality and fast shipping. Would Highly recommend.
