Norton 66252836967 Type 12 Grinding Wheel 6in 60 Grit

Product Description

The NORTON 66252836967 is a Type 12 grinding wheel designed for precision tool grinding and sharpening applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and surface finish on steel tooling and similar workpieces. The wheel runs at a maximum of 4,140 RPM and carries a K hardness code, placing it in the medium grade range. At 6 inches in diameter with a 0.5 inch thickness and a 3/8 inch face width, it is sized for bench grinders and surface grinding equipment used in tool rooms and maintenance shops.

This wheel suits tool room operators, machinists, and maintenance technicians who sharpen or re-profile cutting tools on bench or pedestal grinders. The aluminum oxide abrasive is well suited to ferrous materials including high-speed steel tool bits, drills, and lathe tools. The Type 12 form provides a defined face width for controlled contact on cutting edges. The 1-1/4 inch hole size fits standard arbors found on bench grinders commonly used in light industrial and trade shop environments.
