Medium Duty Portable Punches are for medium punching power (up to 5 tons). They are highly portable and of a size that will fit any tool chest or truck locker. The leverage design of these tools assures easy linear operation.
Maximum Rated Capacities:*

  • No. 7A - 2.5 tons
  • No. 8 - 5 tons
  • Two Hand Linear Operation 

 

These punches are similar except for punching capacity. Unlike other similar tools, these punches will punch and strip inside a 90° arc movement of the lever. And, the upper handle will not disengage when moved to either extreme.

Options include a bench mounting base, with a 3" - 3" 3/4" x 5" tapped base table; and a factory reversal of the upper handle to provide front pull-down operation when the tool's intended use is as a bench mounted unit.
