Customer Reviews (4.4 / 5 · 5 reviews)

Madison ★★★★★

The runout on this JT2 to ER-25 chuck is impressively tight—I measured it at just under 0.0002" with a test indicator. It holds my collets securely and makes swapping tools quick on my mill.

Penelope ★★★★★

The 0.0002" TIR on this JT2 to ER-25 chuck is spot-on for my milling work—collets seat firmly with no wobble. Exactly what I needed for consistent precision cuts.

Charlotte ★★★★★

The hardened and precision-ground finish feels solid in the hand, and the runout is impressively tight—my test indicator barely budged. It's holding my collets dead true in the mill spindle.
