Flexovit Type 28 Depressed Center Grinding Wheels are made for angle grinding applications including weld grinding, beveling, snagging, and other surface preparation jobs requiring moderate to heavy stock removal. The Type 28 'saucer' shape allows the operator to aggressively grind at angles less than 15 degrees, improving operator comfort. The concave shape also provides wider surface contact for grinding broad surfaces. Wheels are 1/4 " thick, with 3 full diameter high tensile fiberglass reinforcements for maximum safety.
