Daniel X. ★★★★★

I’m a machinist and this collet set covers almost every common size I need. The 1/8" up to 31/32" range is exactly what I was after, and they all seat smoothly in my ER-40 holder.

Evelyn B. ★★★★★

Picked up this 24-piece set for the mill and every collet from 1/8" up to 31/32" fits snugly in the ER-40 nut with zero runout. The hardened steel has held up great on a few heavy cuts so far.

Zoe J. ★★★★★

The machining shop had zero of these sizes on hand, and now I've got every oddball fraction I could possibly need, from 1/8" up to 31/32". The steel feels solid and the slots are cut cleanly, no burrs on any of the 24 pieces I've inspected so far.
