CGW 59081 7" X 1/2" X 1-1/4" T1 RA-46H12 Porous 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel is designed for precision surface grinding with a focus on material removal efficiency. The wheel features a porous structure that supports a friable ruby aluminum oxide abrasive, which offers a balance of toughness and sharpness. This combination contributes to effective stock removal while maintaining a consistent form because the material can fracture to expose fresh cutting edges during use. The configuration is suitable for grinding tasks that require control over size and finish, making it a practical choice for applications involving tool steels and other difficult-to-machine metals.
Key construction details include a 7-inch diameter with a 1/2-inch wheel thickness and a 1-1/4-inch arbor/shank diameter, aligned with Type 1 wheel geometry. The RA-46 grit designation identifies a coarse-to-medium abrasive surface intended for higher material removal rates, while the H hardness grade indicates a relatively rigid wheel that resists smearing and provides stable cutting characteristics under typical surface grinding conditions. The combination of grain type, porosity, and form-holding behavior supports predictable wheel performance in rough grinding scenarios, contributing to a controlled approach to achieving the desired finish.
This wheel is suitable for use on ferrous materials where rough grinding is needed before finishing passes. It is important to verify machine spindle compatibility with the 1-1/4" arbor and to ensure appropriate grinding parameters are used to avoid glazing or wheel chatter. When selecting wheels in this family, consider the balance between removal rate and surface quality, and confirm that the wheel’s diameter, thickness, and arbor size match your grinder’s specs. Each wheel is packaged as an individual item, with larger orders commonly configured to your procurement needs.
