Norton 66252916214 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252916214 is a Type 1 surface grinding wheel engineered for precision stock removal on hard carbon steels, soft carbon steels, and tool steels. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. Constructed from aluminum oxide abrasive in a vitrified bond, this ruby-colored wheel carries a 46-grit coarse grade and a G hardness rating, placing it in the soft-to-medium hardness range ideal for aggressive cutting action on hard workpiece materials. Rated at a maximum of 3,600 RPM, it is suited for production surface and cylindrical grinding applications performed by machinists and toolroom professionals.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its coarse 46-grit specification makes it appropriate for high-material-removal passes on hard carbon steel and tool steel workpieces where cycle time and stock removal rate are priorities. The vitrified bond provides rigidity and free-cutting action, maintaining form throughout the wheel life. It is a common choice in toolroom, production machining, and maintenance grinding environments.

Key Features

• Aluminum oxide abrasive construction for effective grinding of carbon and tool steels
• Vitrified bond delivers rigidity and consistent free-cutting performance
• 46-grit coarse grade for aggressive stock removal
• G hardness code (soft-to-medium range) supports cool, efficient cutting on hard workpiece materials
• Porous wheel structure promotes chip clearance and reduces heat buildup
• Type 1 flat wheel profile with no recess and no taper for straightforward mounting

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Rated for hard carbon steels, soft carbon steels, and tool steels per manufacturer specification. Series designation 48A Type 1; specification code 48A46-GVP2.

Installation Notes

Grinding wheel installation and dressing should be performed by a qualified machinist or toolroom technician following ANSI B11.9 safety standards for grinding machines. Before mounting, inspect the wheel for cracks or chips using the ring test; never mount a damaged wheel. Power down and lock out the machine before changing wheels. Verify spindle speed does not exceed the 3,600 RPM maximum rating stamped on the wheel before operating.
