Home Products Tool Holders HSK Tooling System HSK Tooling System

HSK is a German acronym that means "hollow taper shank" and serves as the hollow taper interface that connects to HSK machines using flange contact.

ISO 12164/DIN 69893/ASME B5.62

Selected materials and strict control of dimensional accuracy for the optimum quality. We offer a wide range of standard holders to meet all production requirements.

Available HSK types include A, E and F. HSK sizes include 25, 32, 40, 50, 63, 80, 100 and 125.

Premium Material Selection

Materials play a critical role for HSK tool holders, as they are hollow taper shanks, to ensure optimum performance. BIG DAISHOWA uses carefully selected high-grade alloy steels. BIG DAISHOWA uses die steel materials for HSK40 and smaller where the cross-section of shank taper is very thin.

Drive Key Form

HSK Shanks according to Form A are designed to carry out torque transmission by the round-shaped key-way at the end of the taper. Because of the importance of this round-shaped geometry, BIG DAISHOWA provides finishing of this feature after heat treatment.

Important Tool Retention Feature

Internal clamping of HSK tools is defined by the location of highly concentrated forces from the machine tool. The accuracy and position of this form will affect the rigidity, repeatability, and precision of tool holders. BIG provides finish machining of this area after heat treatment.
