Tuffcote 601

Tuffcote 601 is CUMI’s advanced composite abrasive grain featuring a tough fused alumina core coated with a fine sol-gel alumina microstructure. The sol-gel layer offers sharp, self-sharpening edges for aggressive cutting, while the core provides strength and stability. This unique design enables cooler cutting, reduced burn risk, and consistent performance under high grinding pressures. Ideal for precision applications, Tuffcote 601 delivers superior surface finish across hard-to-grind materials.
