Norton 66252916223 Surface Grinding Wheel 46 Grit 7 in

Product Description

The NORTON 66252916223 is a Type 1 surface grinding wheel designed for precision stock removal on soft carbon steels, tool steels, and super alloys. Built with white aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability throughout the grind. At 46 grit with an H hardness code (coarse grade, soft wheel hardness rating), it removes material aggressively while remaining semi-friable to resist loading. Rated to 3600 RPM, it is suitable for both wet and dry operation. Weighing 1.5 pounds, the wheel is straightforward to mount and balance for standard surface grinding setups.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The 38A Type 1 series is a widely used specification in tool rooms and production grinding operations where consistent aluminum oxide performance is required on ferrous workpieces. The porous structure promotes coolant flow and chip clearance, making it well-suited for applications where heat management at the workpiece is a priority.

Key Features

• White aluminum oxide abrasive for consistent, repeatable cutting on ferrous materials
• Vitrified bond provides rigidity and thermal stability during grinding
• 46 grit coarse grade for aggressive stock removal
• H hardness code (soft wheel hardness) reduces glazing on softer workpiece materials
• Porous structure supports wet and dry operation with effective chip evacuation
• No recess, no taper — standard Type 1 straight wheel geometry

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. Specification 38A46-HVP2.

Installation Notes

Installation should be performed by a qualified grinding machine operator following ANSI B7.1 safe mounting practices. Always ring-test the wheel before mounting and ensure the machine spindle speed does not exceed the 3600 RPM rating stamped on the wheel. Use proper blotters and flanges rated for the wheel diameter, and dress the wheel after mounting before taking the first cut. Power down and lock out the grinder before changing wheels.
