Norton 66252836573 Grinding Wheel 6in 120 Grit Silicon Carbide

Product Description

The NORTON 66252836573 is a Type 1 bench and pedestal grinding wheel designed for precision material removal and tool sharpening on stationary grinders. Built with green silicon carbide abrasive and a vitrified bond, this wheel delivers consistent cutting action on hard, brittle materials including carbide tooling, ceramics, cast iron, and non-ferrous metals. At 120 grit, it falls in the extra fine grade range, making it suited for finishing passes and light stock removal where surface quality matters. The wheel measures 6 inches in diameter, 1/2 inch thick, and carries a 1-inch arbor hole. Rated to a maximum of 4,140 RPM, it is installed and serviced by machinists, tool and die technicians, and maintenance professionals working with bench or pedestal grinder setups.

This wheel is intended for bench and pedestal grinder applications where a fine-grit silicon carbide wheel is required. Green silicon carbide is the preferred abrasive for grinding cemented carbide inserts, ceramic materials, and similarly hard or brittle workpieces. The extra fine 120-grit specification makes this wheel appropriate for finish grinding and edge honing rather than aggressive stock removal. A bushing is included to accommodate different arbor sizes on standard bench grinders. The non-porous, vitrified-bond construction provides a rigid cutting structure that holds form well during use.

Key Features

• Green silicon carbide abrasive — optimized for hard and brittle materials such as carbide and ceramics
• 120 grit extra fine grade for finish grinding and precise edge work
• Vitrified bond provides rigid, consistent cutting structure
• Type 1 straight wheel profile fits standard bench and pedestal grinders
• 4,140 RPM maximum speed rating
• Bushing included for arbor size compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for standard 6-inch bench and pedestal grinders accepting a Type 1 straight wheel with a 1-inch arbor hole.

Installation Notes

Bench and pedestal grinding wheels are installed by machinists or qualified maintenance technicians. Always power down and lockout the grinder before mounting or changing wheels. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 standards. Never exceed the maximum RPM stamped or listed on the wheel, and ensure the grinder guard is properly reinstalled before powering the machine.
