Proxxon Micromot steel collets

1 piece in sizes 1.0 mm, 1.5 mm, 2.0 mm, 2.4 mm, 3.0 mm, and 3.2 mm. Comes with a clamping nut and a base for storage. Micromot steel collets are hardened and provide high, consistent clamping force. They maintain the necessary accuracy even after prolonged use and are incomparable to unhardened, 4-slit collets as well as those made of brass or aluminum. The 3-slit design, which is significantly more difficult to manufacture than the 4-slit design, creates a better seat. This is important for the concentric clamping of shafts with a small diameter.
