Norton 66252916218 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 66252916218 is a Type 1 surface grinding wheel engineered for precision stock removal on a range of ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel operates at up to 3600 RPM and delivers consistent, controlled cutting action. At 7 inches in diameter, 0.5 inches thick, and with a 1.25-inch arbor hole, it fits standard surface and cylindrical grinding machine spindles. The 46-grit, G-hardness (coarse grade) construction makes it well suited for aggressive material removal while maintaining dimensional control. Licensed HVAC, machining, and tool-room professionals specify this wheel for production and maintenance grinding applications.

This grinding wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs on soft carbon steels, tool steels, and super alloys, supporting both wet and dry operation. The pink aluminum oxide grain is semi-friable, allowing controlled breakdown that exposes fresh cutting edges during use. This makes the wheel a reliable choice in tool rooms and production shops where consistent finish and wheel life matter.

Key Features

• Type 1 flat wheel profile — no recess, no taper — for straightforward mounting on standard arbors
• 46 grit, G hardness (coarse grade) for high material removal rates on ferrous metals
• Aluminum oxide abrasive, semi-friable, for self-dressing cutting action
• Vitrified bond provides rigidity and porosity for efficient coolant flow in wet grinding
• Rated to 3600 RPM maximum operating speed
• Compatible with wet or dry grinding operations

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys. Fits spindles accepting a 1.25-inch arbor hole.

Installation Notes

Wheel mounting and dressing should be performed by a qualified grinding machine operator or maintenance technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 3600 RPM maximum speed rating. Power down and lock out the machine before changing wheels. Use appropriate flanges and blotters as specified by the machine manufacturer.
