Norton 66252836520 Surface Grinding Wheel 6in 46 Grit

Product Description

The NORTON 66252836520 is a Type 1 surface grinding wheel designed for precision material removal on ferrous metals and high-performance alloys. Built around a white aluminum oxide abrasive in a vitrified bond matrix, this wheel measures 6 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The 46 grit, coarse-grade specification suits applications that require aggressive stock removal while maintaining consistent cut. Rated at a maximum of 4140 RPM, this wheel is installed and dressed by qualified grinding machine operators and abrasive tooling professionals working in tool rooms and production environments.

This grinding wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. It is particularly effective on soft carbon steels, tool steels, and super alloys where a semi-friable, medium-hardness abrasive performs well under varying load conditions. The vitrified bond structure provides rigidity and free-cutting action, making it a practical choice for both light finishing passes and heavier stock removal cycles on manual and CNC surface grinders.

Key Features

• White aluminum oxide abrasive for use on soft carbon steels, tool steels, and super alloys
• Vitrified bond construction delivers consistent cutting action and structural rigidity
• 46 grit coarse grade rated for aggressive stock removal
• Maximum operating speed of 4140 RPM
• Non-porous, non-tapered Type 1 flat wheel with no recess
• Series specification 38A46-KVBE for positive identification and replacement sourcing

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Material applications include soft carbon steels, tool steels, and super alloys as stated by the manufacturer.

Installation Notes

Installation must be performed by a qualified operator following ANSI B7.1 safe mounting standards for abrasive wheels. Always perform a ring test before mounting and confirm the machine spindle speed does not exceed the 4140 RPM maximum rating marked on the wheel. Power down and lock out the grinder before mounting or removing the wheel. Never force the wheel onto the spindle arbor or use flanges that do not conform to the wheel bore diameter.
