Q-max Q Max Sheet Metal Hole Punch Metric 40mm QMA40M

The Q Max 40mm Sheet Metal Hole Punch offers excellent capability for creating substantial diameter holes in sheet metal up to 16 gauge. This popular larger size is ideal for sizeable conduit work, larger cable glands, substantial mounting hardware, and general fabrication requiring a 40mm aperture. Featuring heat-treated cutting edges with a protective black anti-corrosive surface finish, this punch consistently produces clean, burr-free holes. The special load distribution design ensures smooth, even cutting action, making operation efficient even when working with tougher materials within the 16 gauge range. As a larger punch, this 40mm model uses the simplified configuration with threading in the punch itself rather than on the hexagonal screw, eliminating the die nut component. This streamlined design makes assembly quicker and operation more straightforward. A 10mm hexagonal wrench (MC type) is required to operate the mechanism effectively and provide sufficient torque. Features and Benefits: • 40mm diameter perfect for substantial mounting and conduit applications • Operates with 10mm hexagonal wrench (MC type, sold separately) • Simplified configuration without die nut for faster setup • Heat-treated edges provide consistent, durable performance • Produces burr-free holes with no finishing required Specifications: Punch Type: Metric Diameter (mm): 40 Key Type: MC. 10mm Hex Key Pilot Drill (mm): 12.7
