The CGW 34312 is a 7 inch diameter surface grinding wheel designed for heavy stock removal with a precise final finish. Built on a premium AZ-80J blue aluminum oxide grain system, this wheel emphasizes sharpness and durability to support fast material removal while maintaining dimensional accuracy on heat-sensitive alloys and mold steels. The 1/4 inch thickness and 1-1/4 inch arbor size deliver a stable grinding platform suitable for bench or pedestal grinding operations commonly found in facility maintenance and fabrication environments.
Key features include a high-performance premium grain and bond formulation that balances aggressive cutting action with improved wheel life compared with standard WA and PA grade materials. The AZ-80J designation denotes a grade and hardness suitable for demanding grinding tasks at elevated speeds, with active cooling characteristics to help minimize heat buildup during metalworking. This wheel is intended for applications requiring both speed and a controlled, fine surface finish, particularly on heat-sensitive tool steels and mold steels (where alloys are under 58 RC).
Practically, users should verify compatibility with their grinding machine’s RPM capacity (this wheel is listed for use up to 3,760 RPM) and confirm the 7" x 1/4" x 1-1/4" dimensions align with their tooling setup. Packaged as an individual wheel, CGW lists a box quantity of 10 with a consistent bore and grit specification to support standard stocking and replacement workflows in maintenance shops. Regular inspection for wheel wear and proper mounting alignment is advised to maintain performance and safety during operation.
