Customer Reviews (4.8 / 5 · 5 reviews)

Emily ★★★★★

The clamping range from 1/16" up to 1/2" covers everything I need in the shop, and the tool steel feels solid when I torque them down. Each collet sits snug in the holder without any wobble during a heavy cut.

Joshua ★★★★★

The 21mm diameter fits my ER-20 spindle perfectly, and the tool steel holds tight even during heavy cuts. I bought a few to cover my most-used bit sizes, and the clamping range is exactly as described.

Stella ★★★★★

I’ve been swapping out collets for different jobs, and these ER-20s hold my end mills securely without any runout. The 1/16" to 1/2" clamping range covers everything I usually need, and the tool steel feels solid during high-speed cuts.
