Proto Pin Punch Set
Each punch is hardened, tempered and ground with a chemically blackened knurled body.
2 piece pin design allows the tip to have a separate hardness to prevent peining and allows the tip to be produced straighter thus eliminating binding
Chisels and punches feature modified parabolic struck ends and special heat treatment provides long service life with qualities that resist mushrooming and chipping
All products have a black oxide finish with a polished identification panel, marked with the tool number and size for ease of replacement
