The modern connection between machine spindle and tool is the hollow taper shank system (HSK)

• HSK is standardised under ISO 12164
• The main feature of HSK is the taper and face connection

This gives important advantages: Maximum tool change accuracy, high static rigidity, high radial rigidity, small dimensions, low weights, use at high spindle speeds, shorter tool change times because of lower weights and higher machine acceleration.

The HSK-A version is used for automatic tool change on machining centres, turning/milling centres, milling machines and other machine tools.

HSK-A can also be used on machines with manual tool change.

Other HSK versions can of course be supplied by KOMET on request.

Chip bore 10×4.5 included in the standard.
