Mounting & Standardization

The K72 chuck is not standardized as a complete unit (no unified DIN or ISO standard for diameter, jaw geometry, or bolt patterns).
The machine interface, however, is based on common standards such as:

- DIN 6350 (center mounting)
- DIN 55029 (Camlock spindle nose, e.g., D11 / D15)

= This allows for adaptation to nearly any machine, either directly or via adapter solutions.
