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.
Our factory offer a diverse array of blade types including Boron steel dozer Cutting Edge,Manganese dozer Cutting Edge,Carbon steel dozer Cutting Edge,Boron steel dozer End Bit,Manganese dozer End Bit,Carbon steel dozer End Bit,you can select material & hardness by working condition.
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.
Welcome to contact us for more detailed information : we promise that check for cracks, slag inclusion, air holes, bending distortion before shipment. Heat treatment cracks are hidden danger; once used under heavy impact, the cutting edge may crack suddenly and cause safety risk.
