Heavy Duty Portable Punches are for heavy punching requirements. They operate through ball bearing action and rotary operating motion. While considered portable, they are equally adept as stationary bench mounted tools.

  • Maximum Rated Capacities:*
    No. 20 and CTL 20 - 20 tons
  • Rotary Ball Bearing Operation
    (360° equals 1/2-inch punch movement)

These tools offer punching capacities to meet heavier job requirements, and greater versatility in punching flat sheets and angles.

No. 20 and No. CTL20 are similar, except that the frame around the die pocket of the CTL20 is machined to allow punching close to the web of angle iron (9/16" from web to center of hole).

Options for these tools include a ratchet attachment (for No. 20 and No. CTL20) to permit operation in close quarters, pipe handles to provide adequate leverage with minimal effort.


Options include a 48" Pipe handle to permit operation in close quarters and a base attachment for bench mounting.
