The CGW 34003 18" x 2" x 8" T7 91A-46I 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel is designed for heavy stock removal with a precise finish on appropriate materials. This wheel uses premium blue aluminum oxide grain and bond chemistry intended to deliver sharpness coupled with durability, enabling efficient material removal while maintaining control over the final dimensions. Its design supports fast cutting with a cool operating characteristic, which helps reduce heat buildup during grinding of heat-sensitive alloys and high-speed steels (where hardness is noted as under 58 RC), contributing to improved surface integrity when working on mold steels and other challenging substrates.
Constructed as a Type 7 surface grinding wheel, it features an 18" diameter with a 2" thickness and an 8" arbor/shank size, making it compatible with machinery configured for these standard dimensions. The 46-grit, 91AB Premium Blue Aluminum Oxide grain is selected to balance cutting aggressiveness with a controlled finish, appropriate for applications requiring both rapid material removal and a defined surface profile. The wheel’s hardness specification is I, which provides a particular balance of hardness and wear resistance for extended wheel life under the intended load.
When selecting this wheel, users should consider the workpiece material, desired finish, and machine capabilities to ensure appropriate RPM and mounting compatibility. The package quantity is two wheels per box, and the listed RPM rating of 1,485 should be matched to equipment specifications to avoid overspeed conditions. Maintaining proper dressing and truing practices will help sustain wheel performance and surface finish accuracy over time.
