C.S.Osborne 3/8" Arch Punch with Fully Tempered Cutting Edge

Osborne arch punches are drop forged in one piece from the finest special carbon steel in sizes from 3/16" to 2-1/4" diameter. Larger sizes are made with our properly engineered two piece welded construction. A unique feature of the Osborne arch punch is the inside taper which permits the punchings to clear easily through the barrel. Punches have fully polished barrel and black enamel handle. The cutting edge is fully tempered all the way through and properly finished to provide long use trouble free punching. There is no other Hollow punch that can compare.
