CGW 59045 14" X 1-1/2" X 5" T1 RA-46J/K 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel

CGW 59045 is a 14-inch diameter surface grinding wheel designed for heavy stock removal with a precise finish. This T1 RA-46J/K wheel uses Ruby Aluminum Oxide (RA) abrasive, offering a sharp, friable structure that maintains form under demanding grinding conditions. The wheel is suited for tool steels and materials with high chromium content, where aggressive material removal must be balanced with control over size and finish. Its 46-grit designation provides a middle-ground balance between material removal rate and surface finish, while the J/K hardness range indicates a stable yet responsive wheel that can handle varying workloads. The wheel’s construction supports consistent form retention during extended grinding operations, which helps maintain tolerance and dimensional accuracy on workpieces.

The wheel features a 14" diameter, 1-1/2" thickness, and a 5" arbor/shank size, aligning with common large-capacity surface grinders. At a practical operating speed, roughly 1910 RPM, it is suitable for standard grinding machines configured for such wheel dimensions. The combination of RA abrasive chemistry, grit size, and hardness facilitates efficient rough grinding with a controlled finish, contributing to reduced secondary finishing when used in appropriate applications. When selecting this wheel, consider the workpiece material composition, required stock removal rate, and the desired surface finish to determine if the 46-grit RA wheel best meets the machining goals.

This product is packaged as a single wheel per item, with two wheels per box, supporting production planning where multiple wheels are stocked for repeat operations. Proper mounting alignment and dressing practices should be followed to maintain wheel performance and wheel life. Maintain grinder safeguards and ensure compatibility with your machine’s arbor size and speed rating to avoid over-speed or misfit concerns.
