HSK OVERVIEW
HSK TOOLING SYSTEM ISO 12164/DIN 69893/ASME B5.62
Selected materials and strict control of dimensional accuracy for the optimum quality. Wide range of standard holders to meet all production requirements.
AVAILABLE IN HSK TYPE A/E/F HSK SIZES 25/32/40/50/63/80/100/125
PREMIUM MATERIAL SELECTION Since HSK is a hollow taper shank, the material has a critical role for optimum performance. BIG uses carefully selected high-grade alloy steels. Particularly, BIG 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 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. 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.
