Norton 66243530361 Type 11 Grinding Wheel 4 in 60 Grit

Product Description

The NORTON 66243530361 is a Type 11 flaring cup grinding wheel designed for precision tool grinding and off-hand grinding operations. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steels. It measures 4 inches in diameter with a 1-1/2 inch overall thickness and a 1/4 inch face width. Rated at a maximum of 5,730 RPM, it is sized for use on bench grinders and pedestal grinders in shop and maintenance environments. The K hardness code and medium grade make it well suited for moderate-pressure grinding where controlled material removal is required.

This wheel is used in machine shops, tool rooms, and industrial maintenance settings for sharpening cutting tools, deburring, and surface conditioning. It fits bench grinders and pedestal grinders with a 1-1/4 inch arbor hole and a 3 inch hub diameter. The gray aluminum oxide construction handles general-purpose ferrous grinding tasks and is a common choice for tool and cutter grinders in both commercial and industrial facilities.
