460-8746 Cat Genuine Bolt-On Half Arrow Cutting Edge
The 460-8746 genuine half arrow cutting edge is integrally cast from exclusive Cat DH-2 high-strength wear-resistant alloy steel and refined through multiple precision processes including heat treatment, surface hardening and tempering stabilization. Its internal metallographic structure is dense and uniform with sustained stable hardness, achieving an optimal balance between superior wear resistance and excellent impact toughness. Specially optimized for the heavy-duty operational characteristics of the 988K loader, it withstands long-term continuous hard material friction, frequent impact extrusion and high-pressure heavy loads. It maintains stable performance during prolonged operation without deformation, cracking, wear-through or edge passivation. Its exceptional service life far exceeds ordinary aftermarket parts, effectively reducing replacement frequency, minimizing downtime losses and lowering long-term operational costs.
Made under Caterpillar's complete OEM quality control standards, the 460-8746 comes with precise dimensions and fits buckets very well. Once firmly fixed by bolts, it closely attaches to the bucket structure. Even under heavy loads, it remains steady without loosening, shifting or shaking. Its well-designed equal stress layout spreads impact force and friction pressure evenly during repeated digging and loading. This reduces mechanical fatigue on bucket base edges and tooth seats, slows part wear, and helps these key parts work longer.
