Norton 66252835784 Surface Grinding Wheel 60 Grit 6 in

Product Description

The NORTON 66252835784 is a Type 1 straight surface grinding wheel designed for precision material removal on ferrous and non-ferrous metals. Constructed with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and long service life under dry or wet grinding conditions. It measures 6 inches in diameter, 1/4 inch thick, and carries a 1/2 inch arbor hole. Rated at 4140 RPM maximum, it operates at a medium grade with a K hardness code. The 60 grit designation makes it suited for general-purpose stock removal rather than fine finishing. Machinists, tool and die workers, and grinding technicians are the primary installers.

This wheel is used on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure of the wheel assists in chip clearance and heat dissipation during extended grinding operations, making it a practical choice for production runs as well as maintenance grinding tasks.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent stock removal
• Type 1 straight wheel profile with no recess — fits standard surface and cylindrical grinder spindles
• 60 grit, K hardness (medium grade) — balanced between aggressive cut and wheel longevity
• Porous wheel structure aids chip clearance and reduces heat buildup
• Rated for multiple material applications including stainless, carbon steels, tool steels, aluminum, and cast and ductile iron
• Series designation 32A60-KVBE identifies bond and grade for cross-reference purposes

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Verify spindle speed does not exceed the 4140 RPM maximum rating before mounting.

Installation Notes

Grinding wheel installation should be performed by a qualified machinist or grinding technician following ANSI B11.9 and OSHA 1910.215 standards for abrasive wheel machinery. Before mounting, power down and lock out the grinder completely. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM stamped on the wheel or listed in the specifications. Use appropriate flanges and blotters as required by the machine manufacturer.
