Norton 66253246722 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 66253246722 is a Type 1 straight surface grinding wheel designed for precision stock removal and surface finishing on ferrous and non-ferrous metals. Built with an aluminum oxide abrasive and a vitrified bond, this 7-inch diameter wheel operates at a maximum of 3,600 RPM and carries a medium-grade, I-hardness rating. The vitrified bond provides rigidity and open structure for consistent cut rates, making it a reliable choice for surface grinder work in production and tool-room environments. Licensed HVAC and mechanical trades as well as industrial maintenance machinists are the typical end users for this wheel type.

This wheel is suited for surface grinding applications on a range of materials including 400 Series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is rated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The 1-1/4-inch arbor hole fits standard spindle configurations common to benchtop and floor-standing surface grinders found in machine shops and maintenance facilities.

Key Features

• Aluminum oxide abrasive for versatile metal grinding across ferrous and non-ferrous workpieces
• Vitrified bond construction delivers consistent grain exposure and predictable wear
• Medium grade, I-hardness (60I8V32A spec) balances aggressive cut with wheel longevity
• Non-tapered, no-recess Type 1 straight profile for flat surface and OD grinding
• Rated to 3,600 RPM maximum operating speed
• Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1/4-inch arbor. Suitable for grinding 400 Series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machine operator or maintenance technician familiar with ANSI B11.9 and OSHA 29 CFR 1910.215 grinding safety standards. Always confirm the machine spindle speed does not exceed the 3,600 RPM maximum rating marked on the wheel before mounting. Inspect the wheel for cracks or chips using the ring test before each use and never force the wheel onto the spindle. Power down and lock out the grinder before changing wheels.
