Taper Accuracy AT3: Taper ground to AT3 accuracy for maximum contact with spindle.
Taper-to-Pocket T.I.R. 0.0001": Measured from taper O.D. to collet pocket I.D.
Balanced to 25,000 RPM: Factory balanced to 25,000 RPM at G2.5 Custom balancing to 60,000 RPM available.
Ultra Precision Collet: Each collet hand inspected. T.I.R. only 0.0002".
PowerCOAT Nuts: Our PowerCOAT nut holds 70% tighter than standard nuts for best T.I.R. and rigidity.
Balanced Nut: Balanced nut reduces vibration to extend cutting tool life.
Techniks collet chucks are lab-certified for accuracy and balance, and each holder comes with a complete report detailing its performance, with some common metrics being: balance, dimensional accuracy, collet pocket runout (T.I.R.), bore I.D. and taper accuracy.
