The Tribos-Mini toolholder from Schunk directly clamps small tool shanks along the entire axis virtually eliminating collets, collet nuts and inconsistent cutting tool clamping. Designed for medical, dental and micro-level parts, the holder has a runout accuracy of fewer than 3 microns and a balance grade of G2.5 at 25,000 rpm. The toolholder’s “elastic“ material and polygon form in the clamping bore generate direct clamping. No operator interference is necessary. The toolholder is inserted into a press, and a cutting tool is released in less than 30 sec.
