CGW 34411 12" X 1" X 3" T1 AZ-46H 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel

The CGW 34411 12" x 1" x 3" T1 AZ-46H 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel is designed for heavy stock removal with a refined, precise finish. This wheel uses AZ Premium Blue Aluminum Oxide grain and a T1 bonded construction to balance sharpness with durability, supporting faster material removal while helping control heat generation during grinding. Its formulation is aimed at achieving a clean, consistent cut across a range of metals, making it a practical choice for high-precision surface grinding tasks where both speed and finish quality are important.

Constructed with a 12-inch diameter, 1-inch thickness, and a 3-inch arbor/shank size, the wheel is rated for operation up to 2220 RPM. The H hardness grade indicates a relatively rigid bond, suitable for consistent performance on harder workpieces. The AZ-46H combination is noted for being faster and cooler cutting compared with some other abrasive grains, which can help minimize heat-affected zones on heat-sensitive alloys and mold steels when used at appropriate speeds and feeds.

Typical use cases include removing heavy stock while achieving a precise finish on alloy steels and similar materials. When selecting this wheel, ensure compatibility with your grinding machine’s spindle size, speed rating, and wheel mounting requirements. The packaging indicates a two-wheel quantity per box, and the package size is listed as “Each” with a 12" wheel diameter, requiring compatible A- or B-type grinders designed for 12" wheels and the specified arbor size.
