Norton 66252836550 Surface Grinding Wheel 80 Grit 6 in

Product Description

The NORTON 66252836550 is a Type 1 surface grinding wheel designed for precision material removal on surface grinders, cylindrical grinders, and CNC cutting tool machines. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and predictable wear characteristics suited to professional grinding applications. At 6 inches in diameter, 1/2 inch thick, and with a 1-1/4 inch arbor hole, it mounts directly to standard spindle configurations. The 80 grit, K hardness (medium grade) specification positions this wheel for general-purpose stock removal while maintaining controlled surface finish. It is rated to a maximum of 4140 RPM and carries the manufacturer specification code 38A80-KVBE. Licensed grinding technicians and toolroom machinists are the primary installers.

This wheel is suited for use on soft carbon steels, tool steels, and super alloys. The semi-friable aluminum oxide grain self-sharpens under moderate grinding pressure, making it effective across both production and toolroom environments. Its non-porous, non-tapered, no-recess Type 1 flat wheel profile is a standard configuration compatible with most surface grinder and cylindrical grinder setups found in machine shops and industrial maintenance facilities.

Key Features

• Aluminum oxide abrasive with semi-friable grain for controlled self-sharpening
• Vitrified bond construction for rigidity and consistent wheel form retention
• 80 grit medium grade for general-purpose stock removal on ferrous materials
• K hardness code supports use on softer workpiece materials including carbon and tool steels
• Standard Type 1 flat wheel geometry with no recess and no taper for broad machine compatibility
• White wheel color for easy visual inspection of loading and glazing

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for material applications including soft carbon steels, tool steels, and super alloys per manufacturer specification 38A80-KVBE.

Installation Notes

This wheel must be installed by a qualified machinist or grinding specialist familiar with safe wheel mounting procedures. Before mounting, power down and lockout the grinder in accordance with applicable machine safety standards. Always perform a ring test to check for cracks before installation, and never exceed the rated maximum of 4140 RPM. Guard clearances and flanges must conform to ANSI B7.1 requirements for abrasive wheel machinery.
