Weiler® Tiger® Ceramic 6 in type 11 flaring Cup Wheel deliver the next evolution in technology for portable foundry grinding. The ceramic grain leverage an engineered ultra fine microstructure that self sharpens for ultra fast grinding. Along with the high metal removal rate, the low specific cutting energy of Tiger® Ceramic provide a significant increase in product life. The type 11 flared shape feature a flat grinding surface, making them ideal for heavy metal removal, grinding, transitioning, rough beveling and removing crack and flaw. A wide 1-1/2 in rim provide a large grinding zone to minimize grinding time and a 5/8-11 UNC arbor allow for quick spin-on, spin-off product changeover. Specifically designed with performance and versatility in mind, Tiger® Ceramic cup rock are designed for use on medium to high power pneumatic and high frequency electric grinder. These abrasive are suitable for a wide range of application where high material removal rate are demanded. Increase production efficiency, reduce downtime and lower overall process costs with Tiger® Ceramic.
