Weiler Tiger SiC 6 inch type 11 flaring cup wheels deliver the right combination of performance and value when grinding sand castings. The silicon carbide abrasive grains are sharp, hard, and friable, making them very efficient in controlling metal removal on burn-in and burn-on sand castings. The type 11 flared shape features a flat grinding surface, making them ideal for heavy metal removal, grinding, transitioning, rough beveling and removing cracks and flaws. A wide 1.5 inch rim provides a large grinding zone to minimize grind time and a 5/8-11 inch arbor allows for quick spin-on, spin-off product changeover. Specifically designed with performance and versatility in mind, Tiger SiC cup rocks are designed for use on medium to high power pneumatic and high frequency electric grinders. These abrasives are ideal for a wide range of metals often used on cast metals. Click on the Weiler link at the top of this page to shop more quality Weiler products in the Weiler brand store.
