Norton 66252838330 Grinding Wheel 6 in 100 Grit Type 2

Product Description

The NORTON 66252838330 is a Type 2 vitrified silicon carbide grinding wheel designed for precision tool grinding and finishing applications. Measuring 6 inches in diameter with a 1-inch face width and a 1-1/4-inch arbor hole, this wheel operates at a maximum of 3,600 RPM. The 100-grit, fine-grade abrasive removes material evenly and leaves a consistent surface finish. The vitrified bond provides rigidity and free-cutting action, making this wheel suitable for sharpening carbide tooling, ceramic materials, and similar hard, brittle workpieces. It is installed and operated by machinists, tool-and-die workers, and grinding technicians in shop environments.

This wheel is suited for bench grinder and pedestal grinder applications where silicon carbide abrasive is required. It is commonly used to sharpen tungsten carbide cutting tools, drill bits, and similar tooling. The green silicon carbide construction and fine grit make it appropriate for finish grinding passes rather than aggressive stock removal. The non-porous structure and vitrified bond maintain wheel integrity across repeated dressing cycles in production and maintenance shop settings.

Key Features

• Silicon carbide abrasive construction for grinding hard, brittle materials including carbide tooling
• 100 grit fine grade for finish grinding and edge refinement
• Vitrified bond provides rigidity and consistent cut rate
• Type 2 wheel profile with 1-inch face width for broad contact grinding
• 1-1/4-inch arbor hole fits standard bench and pedestal grinder spindles
• Non-porous structure resists loading and maintains cutting efficiency

Compatibility

Designed as an OEM-style replacement or direct-use grinding wheel for bench grinders and pedestal grinders accepting a 6-inch diameter, 1-1/4-inch arbor hole, Type 2 wheel.

Installation Notes

Wheel mounting should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the rated maximum RPM of 3,600; verify the grinder spindle speed before use.
