CGW 58033 12" x 1" x 3" PA-46H pink aluminum oxide surface grinding wheel is designed for heavy stock removal with a precise finish. This wheel uses PA pink aluminum oxide grains, selected for effective grinding of tool steels and hard alloys, while maintaining relatively cool cutting at appropriate feed rates. The H hardness designation indicates a wheel intended for applications requiring a relatively rigid wheel that can withstand higher grinding pressures without excessive loading. The 46-grit size supports both material removal and finishing steps, making it suitable for shaping and sizing tasks on heat-sensitive materials where temperature control is important.
The wheel’s dimensions—12 inches in diameter, 1 inch thick, and a 3-inch arbor/shank compatibility—define its compatibility with compatible surface grinder spindles and arbors. At a rated speed of 2220 RPM, operators should ensure the grinder setup matches or exceeds this speed to achieve expected performance and safe operation. For practical use, this wheel is typically employed in tool steel sharpening and grinding tasks where a balance between stock removal and surface finish is required, especially on hard alloys that benefit from the hardness and grain structure of pink aluminum oxide. The packaging indicates a two-pack quantity, with each wheel packaged individually, which can help with consistent replacement timing and maintenance scheduling.
When selecting this wheel, confirm compatibility with your grinder’s arbor size, flange spacing, and maximum RPM. Proper dressing and truing are recommended to maintain a consistent cutting surface, and users should follow standard safety practices for grinding operations, including wheel guards and PPE appropriate for metal grinding. This product’s specifications are drawn from the provided data and reflect its intended use in facility maintenance and metalworking environments where precise, cool-cut grinding is beneficial.
