Norton 66252830962 Type 11 Grinding Wheel 5 in 60 Grit

Product Description

The NORTON 66252830962 is a Type 11 flaring cup grinding wheel designed for precision tool grinding and surface conditioning applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel operates at a maximum of 4,585 RPM and delivers consistent, medium-grade stock removal at 60 grit. The J hardness code indicates a medium-hard wheel that holds its form well under moderate grinding pressure. At 5 inches in diameter with a 1.75-inch overall thickness and a 1.25-inch arbor hole, this wheel fits standard bench and pedestal grinder spindles. Licensed tradespeople and toolroom machinists install this type of wheel for sharpening cutting tools, reconditioning jigs, and restoring tool profiles.

This wheel is suited for toolroom and maintenance grinding environments where controlled material removal and consistent finish quality are required. The aluminum oxide abrasive is well matched to carbon steel, high-speed steel, and general ferrous tool materials. The Type 11 cup profile provides a large contact face for flat grinding and tool-face work. The non-porous vitrified bond structure supports coolant-free dry grinding in typical toolroom conditions. This wheel is appropriate for professional machinists, toolroom technicians, and maintenance grinding operations in light industrial and commercial settings.
