Arch Punch
Osborne arch punches (Osborne ref149) are drop forged in one piece from the finest special carbon steel. The size ranges from 3mm to 25mm and can be supplied by special order up to 50mm in metric and 7” Imperial.
A unique feature of Osborne punch manufacture is the inside taper that permits the punchings to be easily cleared through the barrel. These punches have fully polished barrels and enamelled handles The cutting edge is fully hardened all the way through and properly finished to provide long use trouble free punching.
There are no other hollow punches that can compare. Use these punches in conjunction with a plastic or wood cutting pad to protect the cutting edge and a rawhide or wood mallet to protect the life of the tool.
