Weiler Tiger aluminum oxide 6 inch type 27 grinding wheels deliver the right combination of performance and value when grinding steel and other metals. The flat profile of the wheel in combination with depressed center allows for a wide range of grinding angles (0-45). These 1/4 inch thick grinding wheels are ideal for heavy stock removal, scale removal, weld removal, weld blending, edge beveling, and torch-cut softening with a right angle grinder.
