Floating Tap Collets by PCM

PCM® Floating Tap Collets are an economical solution to replace expensive tapping sleeves and eliminate tapping error. The PCM ET1 Floating Tap Collets can be used with the Rigid Tapping Function to compensate for pitch error due to the torsional stress that can occur on small taps, eliminating the difference between the tap and the CNC.

The Collets feature 2 or 4 set screws that lock down on the square tang of the tap, eliminaing any tap slippage.

Fits into ANY 'ER' Collet Taper or Holder
