Corner Shear / Corner Notcher Blades, Manufactured by Fernite of Sheffield

Corner notching is a precision metal, cutting process commonly used in sheet metal fabrication to create clean, accurate corner cuts. Corner notching machines, also known as corner shears are robust, easy to operate, and built to meet strict industrial standards. These machines feature precision, engineered settings, including effective blade gap adjustment, making them ideal for fabrication workshops and manufacturing environments requiring repeatable accuracy.

Why Choose a Corner Notcher?

Simultaneous Dual Cuts: Corner notcher blades are designed to make two cuts at once, typically at a fixed 90° angle, although some machines allow for variable angles.

Top or Base, Initiated Cutting: Cutting action can begin either from the top of the blades or from the base, depending on the machine configuration.

Capacity: Notchers are typically used for processing thin sheet metal, often up to 16-gauge in thickness.

Multiple Naming Conventions: Also referred to as corner shears, square notchers, 90, degree notchers, and more, all variations share the same fundamental design, two upper and two lower blades. Rather than punching straight through the material, the blades perform a shearing action similar to scissors.

Blade Design Features

Rake Angle: All notcher blades include a rake-angle, defined as a gradual rise from one end of the blade to the other. This feature helps reduce cutting force and improves cut quality. It is particularly useful for forming components such as metal boxes or for creating short straight or decorative cuts.

Reversible and resharpenable: Fernite’s corner notcher blades are designed for longevity. They can be flipped and re-sharpened to extend service life and maintain optimal cutting performance.
