The CGW 34430 is a large-diameter surface grinding wheel designed for heavy stock removal with a precise, controlled finish. Its 12-inch diameter, 1-1/2-inch thickness, and 5-inch arbor size identify it as a robust option for high-productivity grinding tasks on flat surfaces, where maintaining tight dimensional tolerances is essential. The wheel is built with AZ-46K premium blue aluminum oxide grain, a formulation chosen for a balance of sharpness and durability that supports fast material removal while helping to retain form during repeated cycles.
Construction features include a Type 5 wheel with a 46 grit, which favors a coarser finish suitable for mold, alloy, and high-speed steels. The AZ premium grain is touted for improved cutting efficiency and durability compared to some conventional aluminous oxides, contributing to cooler cutting action that helps minimize heat-affected zones on heat-sensitive materials. The wheel’s K-grade hardness indicates a fairly stiff bonding system, appropriate for maintaining shape under heavy grinding loads and producing consistently flat surfaces.
When selecting this wheel, users should consider compatible grinders and mounting arrangements to accommodate the 12" size and 5" arbor. As with any large surface grinding wheel, proper safety procedures—such as securing the wheel in a compatible grinder, verifying RPM ratings against equipment, and using appropriate personal protective equipment—are essential. This product is packaged as an individual item, with a box quantity of 2, and is suitable for facilities performing precision removal tasks on alloy and tool steels where a sharp, durable wheel is beneficial.
