Q-Max 31M Sheet Metal Punch 31mm dia. Circular

Metric Sheet Metal Punch Circular
Q-max cutter (punch and die), the quickest and easiest way to punch burr-free holes in sheet metal up to 16 gauge (1.6mm approx.)
Heat treated cutting edges with black anti-corrosive surface finish to prevent rusting.
Boxed singly without key, which should be ordered separately.
Simply drill a hole through the sheet metal (large enough to clear the hexagonal screw) then the die and hexagonal screw are threaded through the sheet metal and then onto the die nut and screw die nut. When the hexagonal screw is tightened, using a suitable Hex (Allen) Key, the punch will cut cleanly and evenly through the metal.
