Customer Reviews (4.8 / 5 · 5 reviews)

Matthew ★★★★★

The range from 1/8" to 3/4" covers everything I need for my mill, and each collet slides in smoothly without any wobble. The case keeps them organized, which saves a lot of time digging through drawers.

James ★★★★★

Pulled the 3/8" out of the case and it seated perfectly in the nut on the first try, no wobble or runout that I could notice. Having every size from 1/8" up to 3/4" in one set means I haven't had to order a single collet since it arrived.

Samuel ★★★★★

Finally have the right collet for every bit size I need, and the 1/8" holds my small end mills perfectly. The machining on these feels precise and they run true in the spindle.
