The Milwaukee® ForceLogic™ M18™ Knockout Tool Kit is powerful enough to punch up to 4in. holes in 14-gauge mild steel. Its compact, right angle design delivers the best clearance in tight spaces. The quick connect alignment system delivers easy setup without the weight of the tool and speeds up repetitive punching. The Exact™ punches and dies are rated for both mild and stainless steel punching. Vivid red cross hairs aid in accurate alignment, and the gripping surface on punches enables faster threading.
