CGW 59003 7" X 1" X 1-1/4" T5 RA-46J 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel

CGW 59003 7" X 1" X 1-1/4" T5 RA-46J 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel is a ferrous-focused grinding wheel designed for heavy stock removal with the capability to produce a precise finish and controlled size. The wheel features a 7-inch diameter, 1-inch face thickness, and a 1-1/4-inch arbor/shank size, aligning with standard surface grinding machine specifications and ensuring compatibility with common tool-room equipment. The T5 designation identifies its specific form and conditioning, while the RA-46J construction uses Ruby Aluminum Oxide as the abrasive medium, which is known for a combination of toughness, sharpness, and strong form retention during aggressive material removal tasks.

This wheel is positioned for rough grinding of tool steels and materials with elevated chromium content, offering a balance of high material removal rates and the ability to maintain dimensional accuracy. The 46-grit rating provides a coarse finish suitable for substantial stock reduction before final finishing steps. The J-grade hardness indicates a particular balance between hardness and friability, supporting sustained cutting action without excessive wheel wear under typical high-load grinding conditions. Proper RPM for this wheel is 3,760, which should be matched to the machine spindle speed to avoid wheel damage or unsafe operating conditions.

In practical use, users should ensure correct seating on the appropriate spindle, verify compatibility with their grinding setup, and follow standard safety practices for abrasive operations. The product is packaged as individual wheels, with a box quantity suitable for stocking and rotation in maintenance or production environments. Maintaining the wheel’s balance and inspecting for cracks or glazing before use will help sustain performance and reduce the risk of wheel failure during heavy stock removal tasks.
