HSK Tooling System optimizes performance of the dual-face-contact interface.

HSK is a short and hollow taper tool holder, originated from Germany. HSK is a spindle interface to achieve dual face contact of a taper and a flange between machine spindles and tool holders.

HSK Tooling System optimizes performance of the dual-face-contact interface. (HSK A, HSK E, HSK F, HSK T, HSK shank, HSK TOOL HOLDERS, HSK holder.)

Drive key is important for torque transmission

The torque transmission of HSK-A type is commenced via the drive key grooves located at the smaller end of the taper. The curved surfaces on the outer drive key groove are important. This curved surface is designed to take the required torque. To achieve precise dimensions of the curves and drive key groove width, BIG provides finish machining of all tools after heat treatment.

Premium material selection

Since HSK is a hollow taper shank, the material has a critical role for optimum performance.
For this purpose, BIG uses carefully selected materials with optimal hardness and strength to prevent product failure.
