A quick & easy way to cut out clean holes in sheet metal up to 16 gauge. Special design allows even load during the cutting & produces a burr free hole that needs no extra finishing.
heat treated cutting edges with black anti-corrosive surface finish to prevent rusting.
all punches boxed singly without key, which should be ordered separately.
to use these punches they require a hole to be drilled through the sheet metal (large enough to clear the allen screw) then the die & allen screw are threaded through the sheet metal then onto the die nut & screw die nut. when the allen screw is tightened the punch will cut cleanly & evenly through the metal.
