Roper Whitney Mounting Base for No. 12 Punch

Medium Duty Portable Punches, rotary ball bearing operated, that extend the capacity offered in the Roller Bearing punches 50% while maintaining an equally portable size and weight.

• Maximum Rated Capacity:* 7.3 tons
• Two Handle Rotary Ball Bearing Operation
• 1/2-inch Punch Movement in a 360 Revolution

These punches use rotary ball bearing operation to provide punching capacity in the medium duty range, beyond the capacity of linear operation punches. The two punches are similar, except for the deep throat dimensions of the No. 12 to punch up to 2 1/4″ from the edge and accommodate angles, channels, and flanged materials.

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

* Refer to the Tonnage Chart to determine if the rated capacity of this tool will accommodate 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.
