Customer Reviews (4.8 / 5 · 5 reviews)

Emily ★★★★★

Installed this on my Sieg KX1 and the precision of the collet is noticeably better than the old one, runout is practically gone. The machining on the taper feels very smooth and consistent, which should help with tool life.

Edward ★★★★★

Fits the 3501 perfectly with zero play in the taper, and the machining surface on the mounting flange is clean as a whistle. For a clearance item, this genuine Sieg part looks and runs like it just left the factory.

Daniel R. ★★★★★

Wasn't sure a clearance cartridge would be this clean, but the bearings feel tight right out of the box. Bolted it into the KX1 and the spindle runs noticeably quieter than the worn original.
