Q-max Q Max Sheet Metal Hole Punch Imperial 1" 3/4" QMA134

The Q Max 1 3/4" Sheet Metal Hole Punch is designed for cutting the largest diameter holes in sheet metal up to 16 gauge, making it ideal for substantial industrial installations, large conduit systems, major HVAC ductwork, and heavy-duty fabrication projects requiring generous apertures. This is the go-to size for demanding professional applications. Featuring heat-treated cutting edges with a black anti-corrosive surface finish, this punch provides exceptional durability whilst resisting rust in challenging workshop environments. The innovative design ensures even load distribution during cutting, producing burr-free holes that require no additional finishing. To operate, drill a pilot hole large enough to clear the hexagonal screw, thread the die and screw through the sheet metal, then tighten the die nut to cut cleanly and evenly through the material. Supplied individually boxed without a key. This punch requires a Type B 5/16" hexagonal wrench, which should be ordered separately.
