Tiger Ceramic 7 inch type 27 depressed center combo wheels deliver the next evolution in technology for portable foundry grinding. The bond is formulated to eliminate uneven edge breakage or chipping on the wheel edge. This technology advancement improves operator safety by reducing high energy debris during the grinding process, eliminates the need to dress the wheel to regain a workable edge, and provides longer wheel life and increased consistency. The ceramic grain leverages an engineered ultra-fine microstructure that self-sharpens for ultra-fast grinding. Along with the high metal removal rates, the low specific cutting energy of Tiger Ceramic results in a significant increase in product life. Combination wheels offer flexibility and efficiency when switching between cutting and grinding applications. The 1/8 inch thickness makes them ideal for light grinding applications as well as blending parting lines, removing flash, and cutting gates and risers with a right angle grinder. Increase production efficiency, reduce downtime, and lower overall process costs with Tiger Ceramic.
