What Is a Cross Cut Blade?

A cross cut blade is a straight industrial cutting knife used to cut sheet metal, steel plates, aluminum, stainless steel, and other materials on guillotine shears, flying shears, and cut-to-length production lines.

Unlike circular blades, cross cut blades perform linear cutting by moving vertically against a fixed lower blade. This shearing action produces clean, straight cuts without generating excessive heat or material distortion.

Cross cut blades are widely used in steel service centers, metal fabrication workshops, automotive manufacturing, shipbuilding, and heavy industrial production lines.

What Is a Guillotine Shear Blade?

A guillotine shear blade is a precision-ground cutting tool installed in hydraulic or mechanical guillotine shearing machines. During operation, the upper blade moves downward against the stationary lower blade, generating high shear force that separates the workpiece with minimal burr formation.

The quality of the cut depends on several factors:

• Blade material

• Heat treatment quality

• Hardness consistency

• Edge geometry

• Blade clearance

• Parallelism

• Surface finish

Proper blade selection significantly improves cutting quality, production efficiency, and machine service life.

Advantages of Precision Shear Blades

MetalKeen manufactures industrial shear blades designed for long service life and consistent cutting performance.

Key Benefits

• High wear resistance

• Excellent edge retention

• Uniform hardness

• Precision-ground cutting edge

• High impact resistance

• Low chipping tendency

• Excellent dimensional stability

• Reduced burr formation

• Longer sharpening intervals

• Custom sizes available

Blade Material Options

Different cutting applications require different tool steels.

Material selection depends on plate thickness, material hardness, production volume, and operating temperature. Premium tool steels such as D2, SKD11 and H13 are widely used because they combine wear resistance with toughness for demanding industrial shearing.
