Weiler® Tiger® aluminum oxide 7 in type 27 Grinding Wheel deliver the right combination of performance and value in foundry grinding application. The bond is formulated to eliminate uneven edge breakage or chipping on the wheel edge. This technology advancement improve operator safety by reducing high energy debris during the grinding process, eliminate the need to dress the wheel to regain a workable edge and provide longer wheel life and increased consistency. Aluminum oxide grain provide a consistent cut rate when grinding metal. The flat profile of the wheel in combination with a depressed center allow for a wide range of grinding angle (0 to 45). These 1/4 in Grinding Wheel are ideal for heavy stock removal, removing crack and surface imperfection, blending parting line, removing flashing on edge of casting with a right angle grinder.
