A quick and easy way to cut clean holes in sheet metal up to 16 gauge.
The special design produces a burr free hole that needs no extra finishing.
A pilot hole is drilled allowing a connecting bolt to join the punch on one side and the die on the other side of the material. Pressure is then applied by tightening the bolt, (with a thrust washer for ease), thus the hole is literally punched out.
Capacity: 3″, 3-1/2″, 4″ and 4-1/2″ dia, through mild steel up to 1.6mm, stainless steel up to 1mm, sheet copper, brass and aluminum up to 2.0mm.
