Tvardy Automatic Punch 125 mm Model 7170584 — 125mm Hole Punch for Sheet Materials

Tvardy Automatic Punch 125 mm Model 7170584 is a 125 mm punch designed for creating round openings in sheet materials. Made from tool steel, the device produces clean, repeatable 125 mm holes for applications such as HVAC vents, ducting, and metal or plastic sheet fabrication. Its automatic mechanism eliminates the need for a hammer and enables one-handed operation while maintaining precision.

Advantages
