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)

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.
