These self-centering and balanced colletholders enable high-torque transmission and show a high-bending strength.
Total system runout TIR ≤3 μm
Our holistic system consists of a powRgrip colletholder and collet. All components together ensure best runout and accuracy.
Colletholder runout TIR ≤1 μm
Measured from collet cavity to outer taper.
Surface finish max. Ra 0.25
Achieve high clamping force and high transferable torque.
Balancing
100% balanced to G 2.5 @ 25,000 rpm/<1gmm.
PGST - Short Tail
Specifically designed for the extra short PGST collets.
Hi-Q balancing system
Ready to accept Hi-Q balancing rings which allow for the offset of the imbalance introduced by the cutting tool up to 80,000 rpm depending on the balancing rings used. All colletholders with the additional type information “H” in the part number are designed for balancing rings.
Vibration dampening
Our holders offer good vibration dampening to sustain a high surface finish and can prevent cutting force alterations.
