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)

Great price! No vibration at 7500 rpm. They don't stick in the spindle. Very happy with these.

They are made a little rough on the non-essential fit and finish but all seem to work well enough. I use one of these dedicated to every drill I use. They are cheap enough to keep setup for when I need them.

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.
