Norton 66252830837 Type 6 Grinding Wheel 5 in 60 Grit

Product Description

The NORTON 66252830837 is a Type 6 straight-cup grinding wheel engineered for precision tool grinding and surface grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and controlled cutting action. It carries a 60-grit medium grade with a J hardness code, making it well-suited for moderate material removal on steel and ferrous metals. The wheel measures 5 inches in diameter with a 1.5-inch overall thickness and a 0.375-inch face width. Rated to a maximum of 4,585 RPM, it is sized for bench grinders and tool-and-cutter grinders used by machinists and industrial maintenance professionals.

This wheel is a standard fit for bench grinder and tool-and-cutter grinder setups in machine shops, manufacturing facilities, and industrial maintenance environments. The 1.25-inch arbor hole accommodates common spindle configurations found on mid-range grinding machines. The medium-grade aluminum oxide construction handles carbon steel, high-speed steel, and general ferrous tooling. It is sold individually and is appropriate for technicians performing routine tool sharpening, reshaping, or surface cleanup work.

Key Features

• Type 6 straight-cup wheel geometry suited for tool and surface grinding
• 60-grit aluminum oxide abrasive for medium stock removal on ferrous metals
• Vitrified bond for consistent wheel breakdown and cutting action
• J hardness (medium) balances wheel wear against workpiece surface finish
• 4,585 RPM maximum speed rating for safe use on standard bench grinders
• Non-porous construction for predictable performance in dry grinding

Compatibility

Designed as an OEM-style replacement or standard-use grinding wheel for bench grinders and tool-and-cutter grinders with a 1.25-inch spindle arbor and a Type 6 wheel compatibility.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with ANSI B7.1 grinding wheel safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using a ring test before mounting, and confirm the machine speed does not exceed the 4,585 RPM rating stamped on the wheel. Use the correct flanges and a blotter gasket as required by the machine manufacturer.
