Heavy-Duty Cutting Edges & End Bits

Maximize Your Blade Life and Earthmoving Efficiency

Welcome to your premier source for high-performance Cutting Edges and End Bits. Designed to withstand the most abrasive environments, our Ground Engaging Tools (G.E.T.) deliver exceptional wear resistance and impact strength. Whether you are operating in sandy soil, hard rock, or frozen ground, our edges keep your blades sharper for longer, reducing downtime and maximizing productivity.

Premium Material & Advanced Metallurgy

The lifespan of a cutting edge depends entirely on its material. We offer two premium material grades tailored to your specific working conditions:

Heat-Treated Boron Steel (30MnB / 28MnB): * Hardness: 46–52 HRC

Best For: High-impact and highly abrasive environments (rock, gravel, mining). Through-hardening ensures consistent wear resistance from the surface to the core, preventing cracking or breakage.

High-Carbon Steel (80# Carbon Steel / 45# Mn):

Hardness: 28–32 HRC (surface hardened variants available)

Best For: Low-to-medium impact applications (soft soil, sand, snow plowing). A highly cost-effective choice for standard earthmoving tasks.

Our Manufacturing Edge: Precision CNC drilling and countersinking ensure exact bolt-hole alignment, while advanced heat-treatment eliminates internal stress to prevent premature cracking under heavy loads.
