Norton 66253246841 Surface Grinding Wheel 46 Grit 8 in

Product Description

The NORTON 66253246841 is a Type 1 vitrified surface grinding wheel designed for precision material removal on soft carbon steels and tool steels. Built on the Gemini Precision Vitrified Grinding Wheels platform, this wheel uses an aluminum oxide abrasive with a coarse, 46-grit cut and an H hardness code rating. The vitrified bond provides rigidity and consistent performance under coolant. At 3,600 RPM maximum speed, this wheel is rated for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It weighs 3.73 pounds and is a standard no-recess, no-taper Type 1 profile.

This wheel is suited for bench-top and floor-standing surface grinders used in machine shops, tool rooms, and production grinding environments. Its coarse 46-grit aluminum oxide composition makes it effective for stock removal passes on soft carbon steels and tool steels. The porous structure improves chip clearance and reduces heat buildup during extended grinding cycles. Applications include flat surface grinding, tool reconditioning, and initial stock removal before finish grinding operations.

Key Features

• Aluminum oxide abrasive with 46 grit for coarse-grade stock removal
• H hardness code vitrified bond for rigidity and coolant compatibility
• Type 1 flat wheel profile with no recess and no taper
• Porous structure promotes chip clearance and heat dissipation
• Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines
• Rated to 3,600 RPM maximum operating speed

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels and tool steels. Fits spindles requiring a 1-1/4 inch arbor hole.

Installation Notes

Mounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the 3,600 RPM maximum rated speed marked on the wheel.
