Norton 66253246901 Surface Grinding Wheel 12in 60 Grit

Product Description

The NORTON 66253246901 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for high-stock-removal and precision finishing applications on a wide range of ferrous and non-ferrous materials. Measuring 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, the wheel carries a 60-grit medium grade with a K hardness code rating. The vitrified bond offers consistent cut rate and thermal resistance under continuous grinding cycles. Rated at a maximum of 2705 RPM, this wheel suits surface grinders, cylindrical grinders, and CNC cutting tool machines used in production and toolroom environments. It weighs 8.4 pounds and ships as a single unit.

This wheel is well suited for toolroom and production grinding operations where dimensional accuracy and surface finish quality are priorities. It handles 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The non-porous, non-tapered, non-recessed straight-wheel profile simplifies mounting and dressing. Typical users include tool and die makers, machine operators, and maintenance machinists working with surface grinders and cylindrical grinding equipment in industrial or job-shop settings.

Key Features

• Aluminum oxide abrasive grain provides durable, consistent cut performance across ferrous and non-ferrous metals
• Vitrified bond delivers thermal stability and free-cutting action throughout the wheel life
• 60 grit medium grade balances material removal rate with achievable surface finish quality
• K hardness code suits a broad range of workpiece hardnesses without excessive glazing or loading
• Type 1 straight-wheel profile with no recess and no taper for straightforward mounting on standard arbors
• Maximum 2705 RPM rating — verify machine speed before mounting

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 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 machinist or grinding equipment operator following all applicable ANSI B11 and OSHA grinding safety standards. Always confirm the machine spindle speed does not exceed the 2705 RPM maximum before mounting. Ring-test the wheel for cracks before installation and never over-tighten the flange hardware. Power down and lock out the grinder before changing wheels.
