CGW 34320 7" x 1/2" x 1-1/4" T1 AZ-46J 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel is designed for precision surface grinding with heavy stock removal capabilities. This wheel utilizes AZ - Premium Blue Aluminum Oxide grain and bond technology, selected for a balance of sharpness and durability. The result is a wheel that can effectively cut through hardened materials while maintaining a consistent finish, making it suitable for applications where both speed and precision are required.
Constructed as a Type 1 wheel with a 7 inch diameter, 1/2 inch thickness, and a 1-1/4 inch arbor, the wheel is engineered for use on high-speed grinders, offering a practical blend of rigidity and cutting efficiency. The AZ grain shifts to faster, cooler cutting compared to some other ceramic or conventional aluminums, which helps minimize heat buildup in heat-sensitive alloys and mold steels. The 46 grit size positions this wheel for substantial material removal while still delivering a controlled finish, and the J hardness designation indicates a balance between hardness and grain retention for repeated passes.
This wheel is intended for heavy stock removal and precise sizing where a reliable finish is important. It is particularly suitable for grinding alloy steels and mold steels, including high-speed steels with Rockwell hardness up to around 58 RC, where heat management and grain sharpness are critical. When selecting this wheel, verify compatibility with your grinder’s spindle size and RPM rating, and ensure proper wheel mounting and balancing practices are followed to maintain performance and safety on metalworking operations.
