CGW 34080 20" X 6" X 12" T7 83A-46G 46-Grit White Aluminum Oxide Surface Grinding Wheel

The CGW 34080 is a large-diameter surface grinding wheel designed for heavy stock removal and precise finishing on a variety of ferrous materials. This wheel measures 20 inches in diameter, 6 inches thick, and has a 12-inch arbor, making it suitable for use on heavy grinders that require substantial wheel mass to maintain rigidity during prolonged stock removal and high-heat applications. It is built with a 83A White Aluminum Oxide grain, providing a balance of toughness and cutting efficiency for general purpose surface grinding tasks.

Constructed as a Type 7, this wheel features a 46-grit size and a hardness grade of G, which supports a controlled balance between cut rate and wheel life for applications that involve heat-sensitive steels and high-speed steels. The 46-grit designation indicates a coarse to medium-coarse grit suitable for removing more material while still delivering a workable surface finish, making it a practical choice for manufacturers and shops that need to recover or refurbish large components efficiently. The wheel is intended for use where easy cutting action on all surfaces is desired, with the added capability of handling heavy stock removal when needed.

When selecting this wheel, consider the compatibility with compatible grinding machines and chuck arbor arrangements, along with the wheel’s RPM rating of 1623 to ensure safe operation at the intended wheel speed. The package size is listed as one wheel per box, which aligns with common usage in larger grinding setups where single-wheel replacements are standard. Proper mounting, dressing, and truing practices should be followed to achieve the indicated performance and finish outcomes.
