Osborne arch punches are forged in one piece from the finest special carbon steel in sizes from 1/8” to 21/8” 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. The cutting edge is fully hardened all the way through and properly finished to provide long use trouble free punching. Original and correct design for cutting. Meet government standards

Carbon is a composite material and differs significantly from quasiisotropic materials like steel or aluminium. As with glass fibrereinforced plastics, the material properties depend on the direction. With a density of approx. 1.6 g/cm³, the material is very light, while maintaining good rigidity and vibration behaviour. If you want to increase the rigidity of a GRP component, it is often sufficient to use a blend of glass and carbon fibres.
