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.
* Refer to tonnage chart to determine if the rated capacity
of this tool will accomodate the type and thickness of metal and the size and shape hole that
you will be punching. Do not, under any condition, exceed the rated capacity of this tool.
