CGW 34309 7 inch diameter surface grinding wheel with a 1/4 inch thickness and 1-1/4 inch arbor fits common stationary and toolroom grinders. This wheel uses AZ-60J premium blue aluminum oxide grain designed to balance sharpness and durability, enabling efficient stock removal while delivering a precise finish. The 60 grit size supports faster material removal with controlled surface quality, and the T1 (straight) wheel form aligns with typical right-angle grinding applications. The wheel’s aluminum oxide composition is selected for compatibility with a range of metals, including heat-sensitive alloys and mold steels, helping to minimize heat buildup during cutting thanks to its abrasive characteristics and bond matrix.
In practice, users can expect notably fast, cool-cutting performance appropriate for grinding high-speed steels and other steel varieties where thermal management is important. The AZ-60J specification emphasizes a balance between aggressive material removal and the ability to maintain dimensional accuracy, which can be critical when finishing and preparing parts prior to welding, fitting, or final machining steps. When selecting wheels for muffled chatter or zone-specific stock removal, consider whether a 7" wheel with 1/4" thickness provides the right balance of rigidity and contact area for your grinder and workpiece diameter.
This package is offered in a size and style that aligns with standard 7" diameter grinding setups, with a center arbor compatible with common 1-1/4" mounting requirements. The product is sold as individual wheels or in boxed quantities per CGW’s packaging options, supporting batch purchases for maintenance inventories. As always, confirm grinder compatibility with the wheel dimensions and RPM rating (3760 RPM) to ensure safe operation and optimal performance.
