Qmax Chassis Round Punch 16mm – Sheet Metal Hole Marking

The Qmax Chassis Round Punch is a precision tool designed for marking and punching clean, accurate holes in sheet metal and thin materials. With a 16mm diameter head and bolt-through design, simply align through a pre-drilled hole, tighten the nut, and the punch creates a clean circular opening — ideal for car aerials, distribution boxes, control panels, and electrical enclosures. Essential for electricians, panel builders, and metalworkers who need fast, repeatable hole marking without expensive machinery.
