HSK Hybrid G1 Chuck


Guarantee of 3μm of integrated runout accuracy

  • For standard model with the collet chuck, 3μm of integrated runout accuracy is guaranteed.

Easy operation of collet holder with higher precision than that of shrink-fit holder

  • HSK Super G1 chuck adopts collet holder system, and has the same or better runout accuracy as that of the shrink-fit holders, not requiring any other special equipment such as heating device, much curtailing the tool changing time.

Usable up to 50,000min-1

  • Simple and straight outside appearance, having no space of the locknut, controls to minimize the aerodynamic noise and cutting fluid dispersion. Small-sized locknut enables minimizing the floating affection to the balancing.
