Customer Reviews for 2pcs Cat40 Keyless Drill Chucks 5/8" Apu16-120 Accuracy Milling Cnc Chuck Holder

Beautifully ground, no burrs, no chasing threads, just very nice tooling for an outstanding price

I was very impressed with the quality of the tooling. 0.001 or less indicator runout on all of the holders. The only complaint is there are a few sharp edges on the tooling. But for the price I can debur them. I will e using them in an educational setting so the price allowed me to stretch my limited budget.

This is a very nice drill chuck for my semi-production Hass CNC toolroom mill. I'll be buying another! Now that I've used it a few weeks, I prefer it over trying to mount a drill bit in a collet. I'm reserving the collets for larger bits and a couple of end mills that I use regularly.

Run true to +/- .002 No vibration at 6000 rpm's (max speed on my Haas)

This product worked as advertised. I used it in my haas vf2. I use it to hold drill bits on parts where the tolerance is not a big deal. I have not checked parts off the machine to see what the accuracy is but all have been within what was needed. It seats in the spindle just fine and have had no issues with tool changes. I don_ give five stars because nothing is perfect.

Good quality works great

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.
