HSK Shank Tools

Taper and Face Quick-Reference Identification

HSK hollow-stub taper shanks are a widely used DIN standard for machine tools. HSK tools have a simultaneous 1:10 taper, which generates two surface contact areas: face and taper. Compared with traditional steep-taper shanks, HSK shanks are shorter, hollow, and clamp from the inside. They also incorporate drive keys that engage milled key-slots in machine spindles and offer higher static and dynamic stiffness than standard steep taper tooling. HSK tooling includes seven toolholder shank forms: A, B, C, D, E, F, and T. Various machine-spindle receivers are available for each. However, the choice of form depends on application requirements such as torque and spindle speed.

HSK-B HSK-A for general-machining service greater flange support than form A for heavier work

Forms C and D Forms C and D for manual tool changes are variations of forms A and B, but the There are six different shank sizes for form C ranging from 32–100mm gripper groove and chip holes are eliminated. These two forms always have their (1.260–3.937") flange diameter. Form D has five different shank sizes from access holes through the taper for manual clamping. These manual forms are 40–100mm (1.575–3.937") flange diameter. typically used on transfer lines and non-rotating applications for NC lathes.
