Each product within the Milwaukee® knockout system was built upon the principles of reducing the tedious steps of hole making, improving the speed of the process and limiting the fatigue of the user. The FORCE LOGIC™ M18™ 10 ton knockout tool is powerful enough to punch upto 4 in holes in 10 ga mild steel and 12 ga 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® knockout system truly is the easiest way to punch.
