CGW 34032 20" X 3" X 8" T7 91A-46I 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel

The CGW 34032 is a heavy-duty surface grinding wheel designed for precision material removal on metal components. This 20" diameter wheel features a 3" thickness and an 8" arbor/shank size, tuned for high-precision surface grinding tasks where control of stock removal and final dimensions is essential. It employs premium blue aluminum oxide grain (91AB) to deliver sharp cutting action with durable bond characteristics, making it well-suited for applications demanding both speed and a refined finish.

The wheel is configured as a Type 7, granulated to 46 grit with an I hardness/grade, which influences its aggressiveness and lifecycle under typical grinding loads. Its construction supports efficient heat dissipation, contributing to cooler cutting when working with heat-sensitive alloys and mold steels under the specified conditions. This combination is intended to balance material removal rate with surface quality while maintaining tool life in demanding shop environments.

Practical use of this wheel centers on precision surface grinding where tight tolerances and clean finishes are required. When selecting a wheel, ensure compatibility with your grinding machine’s spindle size and RPM rating, and verify that the wheel’s 1623 RPM specification aligns with your equipment to avoid operational hazards. The package quantity is 2 per box, and the wheel is suitable for general-purpose surface grinding tasks on metals, including alloys, where a fine-grain, durable wheel is advantageous. Maintain proper grinding parameters to maximize wheel life and workpiece finish.
