Tool mounts
Selecting the suitable output drive also includes finding the appropriate tool mount. Output drives are
available with various tool mounts. Special output drives, e. g. angle heads with counter bracket, can be
manufactured if needed.
The following tool mounts must be differentiated:
External square with
and without centering
pins
The centering pin is used to hold special tools that require such a pin.
Fig. 4–3:
