CGW 59012 10" X 1" X 3" T1 RA-46J/K 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel

CGW 59012 10 inch x 1 inch x 3 inch T1 RA-46J/K 46-Grit Ruby Aluminum Oxide Surface Grinding Wheel is designed for heavy stock removal with the capability to produce a precise finish that meets tight size requirements. This wheel uses RA - Ruby Aluminum Oxide as its grain, which is known for sharp friable behavior and strong form retention, making it suitable for demanding surface grinding tasks on a variety of steels. The 46-grit size provides a balance between material removal rate and surface finish, while the T1 type and J/K hardness designation indicate a specific combination of grain toughness and bond strength that helps maintain shape under heavy grinding loads.

Constructed to sustain rigorous grinding operations, this wheel integrates a 10 inch diameter with a 1 inch thickness and a 3 inch arbor/shank size. The combination of grain type, grit, and hardness contributes to efficient material removal on tool steels, including those with high chromium content, while supporting a consistent grind across the workpiece. The friable Ruby Aluminum Oxide grain tends to expose sharp edges as the wheel wears, promoting continued cutting action without excessive dwell time. These characteristics help users achieve a controlled finish even when removing substantial material.

Practical use considerations include ensuring proper mounting on compatible grinders and adhering to RPM specifications to maintain wheel integrity. This wheel is packaged in a multi-pack configuration (5 per box), which can support maintenance schedules for busy shop environments. As with all surface grinding wheels, verification of exact compatibility with the machine spindle, guard clearance, and safety practices is essential to ensure effective performance and safe operation.
