Norton 66243529170 Surface Grinding Wheel 80 Grit 3 in

Product Description

The NORTON 66243529170 is a Type 1 surface grinding wheel designed for bench and pedestal grinder applications requiring a hard, consistent abrasive action. Built with silicon carbide grain and a vitrified bond, this wheel operates at a maximum of 10825 RPM and delivers medium-grade stock removal on a wide range of non-ferrous and ferrous materials. At 3 inches in diameter, 1 inch thick, and bored to a 1/2 inch hole, it fits standard small-bench grinder arbors and hand-sharpening setups. H-hardness and 80 grit position this wheel for controlled material removal without excessive heat buildup on the workpiece.

This grinding wheel is suited for trade and shop use where consistent abrasive performance is required on harder-to-grind materials including 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Its compact 3 inch diameter makes it practical for hand-sharpening fixtures and small bench grinders commonly found in HVAC shops, plumbing fabrication areas, and general trade service environments. The vitrified bond provides rigidity and porosity control, maintaining wheel form during use.
