9" x 1/4" TIGER CERAMIC Type 27 Grinding Wheel CER30T 7/8 A.H.

Tiger Ceramic 9 inch type 27 depressed center grinding 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 wheel life.

The flat profile of the wheel in combination with a depressed center allows for a wide range of grinding angles (0-45). These 1/4 inch grinding wheels are ideal for heavy stock removal, removing cracks and surface imperfections, blending parting lines, removing flashing on edges of castings with a right angle grinder.

Increase production efficiency, reduce downtime, and lower overall process costs with Tiger Ceramic.

Features and Benefits

Ultra-fine microstructure allows the ceramic grain to self-sharpen for ultra-high metal removal rates and optimal productivity
Unmatched life means more material removed over the life of the abrasive
Advanced anti-chipping technology improves safety through the reduction of high energy debris emitted during the grinding process
The 1/4 inch thickness makes these wheels ideal for heavy stock removal, removing cracks and surface imperfections, blending parting lines, removing flashing
Triple fiberglass reinforcement provides added strength for aggressive stock removal
Open arbor offers a cost-effective mounting option when using adapting nuts
Best for use on cast iron, ductile iron, white iron, gray iron, cast steel, high nickel alloy and stainless steel
