Customer Reviews (4.8 / 5 · 5 reviews)

Owen I. ★★★★★

I was impressed by the precision-ground finish on this collet chuck—the T.I.R. of 0.0002 inches is reassuring for tight tolerances. Works smoothly with my ER-25 collets right out of the box.

Amelia K. ★★★★★

Jumped right into my R8 spindle and the 0.0002" runout is dead-on, no vibration at all. The hardened steel feels like it'll last forever, and it grips my end mills tight through a heavy cut. Exactly what I needed for better precision on my mill.

Aurora ★★★★★

The runout on this chuck is dead on at the advertised 0.0002", and it's machined smooth enough that my ER-25 collets seat without any fuss. It's a solid, precision-ground piece that feels like it'll outlast my mill.
