Set of 5 Punches wood base provided with set
- Sizes range in diameter from 27.6mm to 49.8mm
- The punch diameter provides 1mm allowance for the thickness of metal
These perfectly match punches are 1mm smaller than the cavity diameters in our dapping blocks. This was done in order to allow for the thickness of the metal being formed. We call them ID punches because the domes formed will have the same inside diameter as the inside cavity of the dapping block.
