The FORCELOGIC™ M18™ 10 Ton Knockout Tool is powerful enough to punch up to 6″ holes in 12 gauge mild steel, and 14 gauge stainless steel. The Quick Connect Alignment System both delivers easy set-up without the tool, and speeds up repetitive punching. EXACT™ punches and dies are rated for both mild and stainless steel punching. Plus, EXACT™ dies have both engraved cross hairs for accurate alignment, and slug removal ports for optimal slug removal. Together, Milwaukee’s Knockout System truly is the easiest way to punch!
