The CGW58021 is an 8-inch surface grinding wheel designed for precision material removal on tool steels and hard alloys. It uses PA-46J pink aluminum oxide grain, configured as an 8 x 1/2 inch wheel with a 1-1/4 inch arbor, Type 1, and a grit size of 46. The pink aluminum oxide formulation is selected for favorable cutting characteristics on heat-sensitive materials, offering a balance between aggressive stock removal and controlled heat generation. The J hardness designation indicates a specific grain bond and wear resistance that supports repeated cycles of grinding at a moderate feed rate while maintaining a stable finish.
This wheel is geared toward heavy stock removal when a precise final dimension is required, and it is particularly suitable for sharpening and grinding tool steel. Its construction aims to provide durability relative to standard WA-grade aluminum oxide wheels when used on tool steel and stainless steel, especially at light to moderate feed rates. Users should monitor wheel performance during longer grinding sessions and be mindful of heat buildup, choosing appropriate cutting parameters to preserve workpiece integrity and wheel life.
Practical use considerations include selecting grinding parameters that reflect the wheel’s 46-grit PA-46J composition and 3600 RPM operating speed. The package size is listed as each with a box quantity of 10, which may influence procurement planning and inventory. This wheel is compatible with standard 1-1/4 inch arbors and should be mounted according to machine specifications and safety practices for surface grinding operations.
