This shredder blade kit is designed for the Vevor Model 250 plastic grinder and includes 6 rotating blades and 2 fixed blades for efficient plastic processing. Made from alloy steel with SKD-11 reinforced material and advanced heat treatment, the blades offer strong wear resistance, impact resistance, and reliable cutting performance. The sharp, burr-free edges help reduce cutting resistance and support more uniform crushing results. A stepped-edge design allows the blades to be re-ground for continued use and lower maintenance costs. It is suitable for processing ABS, PP, PVC, nylon, PS, PC, fiber-reinforced plastics, and similar materials.
