15/64" W10 COLLET (3900-4974)

15/64" W10 Collet Made of high quality tool steel. Hardened and precision ground to highest concentricity. These collets are closed by being drawn back into the collet seating by means of a draw bar. The collets only open a minimal amount. The W10 collets differ from the other pull-type collets because of their external thread, which has a nominal diameter almost identical to the collet shank diameter. The pull-type collets generally only clamp the nominal diameter. To obtain optimal concentricity, it is recommended not to clamp less than 0.1 mm below the nominal diameter. Shipping Weight: 0.1 lbs
