Norton 66252838486 Type 6 Grinding Wheel 6 in 60 Grit

Product Description

The NORTON 66252838486 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, it delivers consistent stock removal on ferrous metals and tool steels. The wheel measures 6 inches in diameter with a 0.5-inch face width and a 2-inch overall thickness. At 60 grit and K hardness, it sits in the medium range, balancing cut rate with surface finish. A maximum operating speed of 3,820 RPM keeps it suited for bench grinders and pedestal grinders running at compatible speeds. Weighing 2.19 pounds, this single-unit package is ready for immediate shop use by machinists, tool-and-die workers, and maintenance technicians.

This wheel is primarily used in tool rooms, maintenance shops, and production environments where tool reconditioning and sharpening are routine tasks. The aluminum oxide abrasive is well matched to carbon steel, high-speed steel, and similar ferrous materials. The vitrified bond provides a rigid, free-cutting structure that holds form through repeated dressing cycles. The 1.25-inch arbor hole fits standard bench grinder and pedestal grinder spindles commonly found in trade and industrial shops.

Installation Notes

Grinding wheel installation and dressing should be performed by qualified machinists or maintenance technicians following ANSI B7.1 safety standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use using the ring test — do not mount a damaged wheel. Ensure the grinder spindle speed does not exceed the 3,820 RPM maximum marked on the wheel.
