Norton 66253042317 Bench Pedestal Grinding Wheel 8in 100 Grit

Product Description

The NORTON 66253042317 is a Type 1 bench and pedestal grinding wheel engineered for precision surface grinding and tool sharpening on stationary bench grinders and pedestal grinder stands. Measuring 8 inches in diameter, 3/4 inches thick, with a 1-inch arbor hole, this wheel features a 100-grit fine aluminum oxide abrasive bonded with a vitrified bond for consistent stock removal and a smooth finish. Rated at a maximum of 3,600 RPM, it suits the standard operating speeds of most bench and pedestal grinder units. Licensed tradespeople and maintenance mechanics rely on this wheel for sharpening cutting tools, deburring metal, and light surface work.

This wheel is suited for use on stationary bench grinders and pedestal grinders in industrial maintenance shops, machine shops, HVAC fabrication environments, and general trade workshops. The fine 100-grit specification makes it appropriate for finish grinding, edge refining, and tool touch-up rather than heavy material removal. The 1-inch center hole accepts standard arbor bushings, and the bushing set is included to fit a range of common spindle diameters. The vitrified bond provides a hard, consistent cutting action that holds up under repeated use across ferrous and non-ferrous metals.

Key Features

• 100-grit fine aluminum oxide abrasive for smooth, precise grinding and tool sharpening
• Vitrified bond construction for consistent cutting action and long wheel life
• 8-inch diameter by 3/4-inch thickness in a standard Type 1 straight-wheel profile
• 1-inch arbor hole with bushings included to fit multiple spindle sizes
• 3,600 RPM maximum speed rating compatible with standard bench and pedestal grinders
• Non-porous structure maintains wheel integrity and reduces loading during use

Compatibility

Designed as an OEM-style replacement or service wheel for standard bench grinders and pedestal grinders accepting an 8-inch diameter, 3/4-inch wide, Type 1 straight wheel with a 1-inch arbor hole.

Installation Notes

Wheel mounting should be performed by a qualified technician following ANSI B7.1 safety standards for abrasive wheel use. Always power down and lock out the grinder before removing or installing a wheel. Inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the maximum rated RPM of 3,600. Use the correct flange size and blotters as required, and allow the wheel to run at operating speed for at least one minute in a guarded position before grinding.
