Norton 66252916210 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252916210 is a Type 1 surface grinding wheel engineered for aggressive stock removal on ferrous metals and difficult alloys. Built with a ceramic abrasive grain and a vitrified bond, it operates at a maximum of 3600 RPM and delivers consistent cut rates across wet and dry grinding applications. At 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole, this wheel fits standard surface grinder spindles without modification. The G hardness code places it on the softer end of the vitrified bond scale, which promotes self-dressing action and helps prevent workpiece burning on harder materials.

This wheel is suited for surface grinding and cylindrical grinding operations in production and tool-room environments. It is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. The coarse 46-grit designation makes it a practical choice for roughing passes and high-stock-removal applications where surface finish is secondary to material removal rate.

Key Features

• Ceramic abrasive grain for aggressive, consistent cutting on hard and abrasion-resistant materials
• Vitrified bond provides rigidity and porosity for efficient chip clearance during grinding
• 46 grit, G hardness (Coarse grade) promotes rapid stock removal with self-dressing behavior
• Rated for wet and dry operation at up to 3600 RPM
• No-recess, no-taper Type 1 flat wheel profile for straight surface and cylindrical grinding
• Purple wheel color for visual identification of the 3SG ceramic series

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a 7 inch diameter, 1/2 inch thick, Type 1 flat wheel with a 1-1/4 inch arbor hole. Rated for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified grinding machine operator or machinist following ANSI B11.9 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test to confirm structural integrity. Power down and lock out the machine before changing wheels. Never exceed the rated maximum RPM marked on the wheel.
