The CGW 34427 12" x 1-1/2" x 5" T5 AZ-46H 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel is designed for heavy material removal with a precise finish on ferrous and alloy steels. This wheel uses AZ premium blue aluminum oxide grain, selected for a balance of sharpness and durability, which supports faster cutting action and extended wheel life compared with standard WA and PA grains. The T5 profile and 46-grit size are chosen to deliver aggressive material removal while maintaining a controlled, fine finish, making it suitable for applications where grind quality and dimensional tolerance are important. The H hardness rating indicates a wheel formulation intended for higher strength materials, enabling stable cutting performance at typical grinding speeds.
The wheel’s construction is tailored to heat-sensitive workpieces, including certain heat-treatable steels, by offering relatively cool-cutting characteristics in high-speed operations. This helps reduce thermal distortion and preserve the integrity of the workpiece while achieving the desired shape and size. The 12" diameter and 1-1/2" thickness provide a substantial contact area for surface grinding, and the 5" arbor/shank size aligns with compatible grinding machines designed for this wheel geometry. Each unit is packaged as a single wheel, with a batch quantity of two per package, reflecting a common maintenance and replacement cadence in facility settings.
When selecting this wheel, verify compatibility with your grinder’s RPM rating and spindle bore to ensure safe operation at or below the wheel’s rated 2220 RPM. The AZ-46H designation and 46-grit size indicate a specific balance of grain exposure and bond, which influences both the aggressiveness of material removal and the wheel’s wear characteristics. This wheel is intended for surface grinding tasks that require a combination of fast stock removal and a controlled surface finish on appropriate workpiece materials.
