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)

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.

Really recommend these. We were able to implement standard tooling buy buying sets of these holders. The er16 holders by orangeA are good too.

A good starter selection of collets for my mill.

Great quality, well balanced, will buy again!

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.
