Slice through sheet metal with total directional freedom using the Magnum MMS4 throatless shear. Unrestricted by a traditional cutting throat, this heavy-duty hand tool allows fabricators to maneuver sheet metal effortlessly, executing long straight passes, sweeping curves, and intricate irregular shapes in up to 16-gauge steel. Equipped with tough, hardened alloy steel blades, it provides extreme mechanical leverage, making it a highly valuable benchtop asset for custom auto body repair and HVAC ductwork fabrication.
Features
- Throatless design – Allows the operator to continuously feed and rotate sheet metal through the blades without hitting a back-stop.
- Hardened alloy blades – The 4-inch cutting edges resist chipping and dulling, providing clean, burr-free cuts even in tough materials.
- Multi-directional cutting – Empowers users to pivot the workpiece mid-cut to create complex shapes and tight, irregular curves.

Frequently Asked Questions
Q: Does this shear need to be permanently mounted? A: Yes, for safe operation and to utilize the full leverage of the handle without the tool tipping, it must be bolted securely to a heavy, stable workbench.
Q: Can I cut thicker materials if they are softer, like aluminum? A: Yes, generally you can cut aluminum that is a few gauges thicker than the maximum mild steel rating, provided it fits cleanly between the open blades.
