Made from high-carbon manganese steel alloy, producing a blade that is both tough and resistant to wear to minimize breakage. With a hardness of Rc 29 ± 5, blade performance is optimized in medium to aggressive environments. Warranted against breakage due to a defect in material and workmanship for the life of the cutting edge. Bolt-On Reversible Blade Bucket Cutting Edges
Wear one side and reverse the edge for twice the life
Pre-drilled extra-hard carbon steel for maximum wear resistance
Side View of Edge Mounted on Bucket
This system makes blade changes simple, fast and inexpensive. You can change worn out bucket edges in minutes, in the field, with hand tools. By using reversible, double bevel flat sections, the wear life of the cutting edge is doubled.
