Weiler Wolverine 7 inch type 27 depressed center grinding wheels deliver a fast cut rate and consistent performance at a good 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 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. The 5/8" - 11 nutted metal hub allows for quick spin-on, spin-off changeover and eliminates cross-threading or sticking to spindle due to heat build-up.
