Q. MAX QMA16M Sheet Metal Punch – 16mm Dia. (6mm Key required).

A Quick and easy way to cut clean holes in sheet metal up to 16 gauge. The special design allows even load during cutting and produces a burr free hole that needs no extra finishing. The cutting edges are heat treated with a black anti-corrosive surface finish to prevent rusting. All punches are individually boxed without a key, which should be ordered separately.
