Need to punch clean, round holes in metal or plastic? This ZUVER hydraulic knockout punch kit makes it easy. It uses a 15-ton hydraulic pump for serious power, cutting through steel, stainless steel, aluminum, plastic, and fiberglass. The kit includes 10 different die sizes – from 1/2 inch all the way up to 4 inches – so you can handle a wide range of jobs. Each die has laser-engraved marks for alignment, and the tool has a comfy non-slip handle and a quick-release valve. Max thickness: 1/8 inch for steel, 1/16 inch for stainless. Comes with a drill bit, draw studs, spacers, and a sturdy carrying case to keep everything organized. Ideal for electricians, plumbers, metalworkers, or serious DIYers who need precise, burr-free holes without using a plasma cutter or hole saw.
