Bosch 1x PRO Punching Die Stainless Steel (67 x 45 mm, Professional Accessory Knockout Tools)

Designed for punching burr-free holes in sheet metal - When you install electrical boxes or switch cabinets and use hydraulic knockout tools to punch through sheet metal, a strong and sharp knockout punch helps you get clean holes you need. We made PRO Punching Die for punching clean and accurate holes with ease. The PRO Punching Die set features a punch with 2 cutting edges that splits the waste material in half and prevents jamming. This means you can make perfect, burr-free holes in steel up to 3 mm thick and stainless steel up to 2.5 mm thick faster. The knockout punch and die in sizes between M16-M40 will help you punch holes up to 40.5 mm in diameter. Use sizes PG9-PG36 to punch holes up to 47 mm in diameter.
