The CGW 34421 is a 12 inch diameter surface grinding wheel designed for heavy stock removal with the capability to achieve a precise finish and controlled dimensions. It features AZ Premium Blue Aluminum Oxide grain paired with a 1 inch thickness and a 5 inch arbor/shank size, enabling compatibility with suitable grinding machines equipped for these wheel dimensions. The wheel’s grain and bond technology is tailored to deliver both sharp abrasive action and durability, which translates into faster material removal while maintaining a stable cut. The 46 grit size and J hardness designation indicate a wheel that strikes a balance between aggressiveness and the ability to sustain a consistent grind, particularly on heat-sensitive alloys and mold steels, where reduced heat buildup is valuable during high-speed operation.
This wheel is noted for its cutting efficiency and cool operation characteristics, which help minimize thermal distortion when grinding alloys and high-speed steels rated below 58 HRC. Compared with alternative grain families, AZ Premium Blue Aluminum Oxide is positioned as a more durable option with sharpness advantages, supporting applications that require both rapid stock removal and a workable edge for finishing. Practical use considerations include selecting the appropriate RPM (the wheel is rated for 2220 RPM) to match equipment capabilities and maintaining correct wheel dressing and truing practices to preserve cut quality and wheel life.
As a 2-pack box quantity of 2 wheels, the CGW34421 package provides the specified wheel size and mounting arrangement suitable for facility maintenance and workshop grinding tasks. Ensure compatibility with your grinder’s arbor size and spindle speed, and follow standard safety practices for wheel inspection, mounting, and operation prior to use.
