Punch

The punch can be reground by a total of approximately 10 mm.

Regrind the grinding surface in accordance with the following

diagram, making sure that it is well-cooled during the process.

Lightly apply fine-grained oil stone to the cutting edge.

Observe a minimum length of 89 mm. Shorter punches must

be replaced (risk of collision).

Note

Dies can not be resharpened.
