Norton 66252830832 Type 6 Grinding Wheel 5 in 46 Grit

Product Description

The NORTON 66252830832 is a Type 6 straight-cup grinding wheel designed for tool grinding and surface grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steels. The 46-grit coarse abrasive provides aggressive cutting action suited to rough grinding and reconditioning work. Rated to a maximum of 4,585 RPM, the wheel measures 5 inches in diameter with a 1-1/2 inch overall thickness and a 3/8 inch face width. The 1-1/4 inch bore fits standard pedestal and bench grinder arbors. Licensed HVAC techs, machinists, and tool room professionals will find this wheel at home on bench grinders and surface grinding setups.

This wheel is suited for stationary bench grinder and pedestal grinder use in tool rooms, maintenance shops, and fabrication environments. The Type 6 straight-cup form is commonly used to grind tool faces, recondition cutting edges, and perform light surface grinding. The K hardness code and vitrified bond maintain wheel shape under steady grinding pressure, making it appropriate for intermittent tool sharpening and general-purpose grinding tasks on harder workpiece materials.

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified personnel familiar with ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Before mounting, power down and lock out the grinder at the source. Inspect the wheel for cracks or chips using a ring test before installation, and never operate the wheel above its maximum rated RPM of 4,585. Use flanges and blotters appropriate to the wheel diameter and arbor size.
