Norton 66253246878 Surface Grinding Wheel 46 Grit 10in

Product Description

The NORTON 66253246878 is a Type 1 vitrified aluminum oxide surface grinding wheel built for aggressive stock removal on a wide range of ferrous and non-ferrous materials. Measuring 10 inches in diameter and 1 inch thick with a 3-inch arbor hole, this wheel carries a 46 grit, H hardness (coarse grade) specification and is rated to a maximum of 2,480 RPM. The vitrified bond and non-porous structure provide consistent cut rates and good wheel life under typical surface grinding loads. At 5.83 pounds, the wheel is suited to production and maintenance grinding environments where a durable, straight-wheel profile is required.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Series 32A construction makes it a practical choice for both production shops and tool rooms where a coarse, fast-cutting aluminum oxide wheel is needed for flat-surface stock removal or cylindrical work.

Key Features

• Type 1 straight wheel profile with no recess and no taper for standard surface and cylindrical grinder spindle mounting
• 46 grit, H hardness coarse-grade aluminum oxide abrasive for aggressive material removal
• Vitrified bond construction for consistent cut rate and thermal stability under load
• Rated to 2,480 RPM maximum operating speed
• 3-inch arbor hole fits standard production grinder spindles
• Compatible material range includes stainless steels, carbon steels, tool steels, aluminum, and multiple cast iron grades

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. 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

Installation should be performed by a qualified grinding machine operator or maintenance technician following ANSI B11.9 and OSHA 1910.215 standards for abrasive wheel machinery. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per manufacturer guidelines. Never exceed the rated maximum RPM of 2,480 and ensure the arbor flange and blotter sizes are appropriate for a 3-inch hole Type 1 wheel.
