1.made with 42CrMo,etc. 2.hardness:HRC52+/-2 3.heat treatment on the surface 4.avaliable in all sizes The dimensions shown on the accompanying illustrations are generally considered Standard. Some die users believe the standard Tongue is preferable, others feel that the Hook Tongue or Safety Tang is safer to use. This may be especially true if the punch is to be used in sections,where weightor dimensions of punch are great, or where stripping pressure would create an extreme downward pull as in the case of a Channel Forming Die. We offer both, however, Standard with tolerances as shown will be furished unless specifications are to the contrary.
