Our aftermarket full sets of Caterpillar D9 Cutting Edge & End Bits replacement are ultra heavy-duty ground engaging tools designed for CAT D9 series large dozers, covering D9N, D9R, D9T models. The Cat D9 large dozers are widely deployed for open-pit mining stripping, massive overburden removal, large volume rock and earth moving, heavy road subgrade construction, stockpile management and land reclamation projects.

We can provide multiple bevel profiles for cutting edges, including double bevel reversible, single bevel, square edge and carbide reinforced version. Our aftermarket Caterpillar end bits have standard flat-cut and cupped hot-forged styles, cupped end bits provide stronger corner wrapping protection for heavy mining conditions. 

We suggest to use high tensile grade 10.9 or 12.9 bolts due to Caterpillar D9 blade edge works under huge impact load. Old bolts often fatigue, so it is better to replace new bolts together while changing cutting edges and end bits. Besides ,it is important to confirm raw material grade and heat treatment process with supplier. Real full through-hardened boron steel edge has uniform hardness through the whole plate. Surface-only hardened edges wear quickly and bend easily under D9 heavy mining load.
