CGW 36255 4-1/2" X 1/4" X 7/8" A24-R Type 27 24-Grit Fast Cut Aluminum Oxide Grinding Wheel

The CGW 36255 grinding wheel is a 4-1/2 inch diameter, 1/4 inch thick, 7/8 inch arbor Type 27 wheel designed for fast material removal on aluminum oxide applications. With a 24-grit, R-grade bond, it is formulated to balance aggressive cutting action with longer wheel life, making it suitable for continuous stock removal on metalwork where a flatter, depressed-center configuration is required. The aluminum oxide grain choice and R-hardness designation translate to dependable performance under heavy loading while maintaining a relatively robust wear profile for shorter cycle times.

This wheel is intended for specialized cutting and grinding tasks on flat or slightly contoured surfaces where a Type 27 wheel can contact the workpiece at an inclined angle. The 7/8 inch arbor size aligns with common angle grinder spindles, and the 4-1/2 inch diameter provides access to tighter contours and smaller work areas often encountered in fabrication, maintenance, and repair operations. The combination of grain type, grit size, and bond hardness influences both stock removal rate and surface finish, so users should select spindle speeds and wheel dressing practices compatible with the manufacturer’s recommendations to optimize performance.

Packaging is listed as per-wheel with a box quantity of 25, which is a practical quantity for shop inventory and job-site needs. When selecting this wheel, verify compatibility with your grinder’s RPM rating and fastening hardware, and ensure appropriate guards and PPE are used during operation. Regular inspection for glazed or loaded segments will help determine when dressing or replacement is required to maintain effective cutting action.
