CGW 34778 12" X 2" X 5" T7 WA-46I 46-Grit White Aluminum Oxide Surface Grinding Wheel

CGW 34778 is a 12 inch diameter, 2 inch thick surface grinding wheel designed for heavy stock removal and precise finishing on a variety of metals. The wheel features WA - White Aluminum Oxide abrasive, which is known for its balance of cutting action and durability on heat-sensitive steels and high-speed steels. This is a Type 7 (side vent) wheel with a 46 grit and I-hardness (hardness grade), suitable for applications requiring controlled stock removal while achieving a specific size and surface finish. The wheel is rated for up to 2220 RPM, aligning with standard industrial grinding equipment operating speeds, and is mounted on a 5 inch arbor/shank configuration as noted in the specifications.

In practice, this wheel supports light to moderate stock removal with consistent performance across multiple surfaces. It is particularly useful when an easy cutting action is needed on various materials, and when grinding heat-sensitive alloys where selectivity and heat generation must be managed. The 46-grit size offers a balance between material removal rate and surface finish, making it suitable for finishing operations following rough grinding or for precision work on components that require tight dimensional control.

Compatibility and handling considerations: verify your grinder accepts a 12" wheel with a 5" arbor and ensure appropriate guards and flanges are used per equipment guidelines. As with all surface grinding wheels, follow manufacturer safety recommendations for mounting, dressing, and truing to maintain wheel integrity and desired finish.
