SHEET METAL CORNER NOTCHERS

Punch Tools engineers industrial sheet metal notchers designed to carve out precise rectangles, sharp V-notches, 90-degree corner reliefs, and specialized, custom shapes along the edges of heavy-gauge flat sheets. Unlike standard manual bench notchers that struggle and bind on thicker materials, our heavy-duty spring-loaded punches deliver smooth, burr-free shearing through tough substrates with minimal effort—achieving beyond CNC-quality results without the slow cycle times.

These versatile corner notchers are engineered for seamless integration into most standard shop power sources, including punch presses, press brakes, ironworkers, and Porta Press systems. There is absolutely no "Armstrong method" required here—say goodbye to struggling with heavy arbour presses or manual hand-crank tools.

Commonly referred to as corner notchers or edge shearing tools, these high-performance production units are essential for removing corners on heavy-gauge aluminum, steel, and composite sheets. They leave clean, exact flaps that are perfectly prepped for folding trays, pans, electrical enclosures, architectural cladding, and structural traffic sign backing frames.

The "Heavy Gauge" Advantage

Standard manual notchers often struggle once you reach .100" material, causing "oil-canning" or denting the aluminum. Our corner notchers can handle up to 0.125" (1/8") aluminum.

• Ensures clean, accurate notches for tight bends and proper fit-up.
• Watch as it notches aluminum with a "nice notch and no burr."
• Beyond aluminum, the corner notcher effortlessly processes ACM and Polycarbonate without destroying the substrate.
