Shearproof Punch and Die Sets

28XX Style Tooling. For manual presses only.

Shearproof tooling is primarily intended for use in stainless steel, where the resistance to deformation is high, but they can also be used in mild steel. Four spring loaded heels extend below the punch cutting surface. One or two of these heels are allowed to enter the die and act as guides before the punch face contacts the material when notching or nibbling holes.

The square shearproof punch is used for square hole punching, square edge notching and nibbling out large square or rectangular holes, either in the center or along the edge of a piece part. It can be programmed into a template or tape and can also be used in conjunction with the precision gaging on all manual presses.

Maximum Material Capacity: 10 gage (.135") Mild Steel or Stainless Steel
