Norton 66253160889 Surface Grinding Wheel 46 Grit 10 in

Product Description

The NORTON 66253160889 is a Type 1 surface grinding wheel engineered for stock removal and precision surface work on soft carbon steels, tool steels, and super alloys. The wheel measures 10 inches in diameter and 1 inch thick with a 3-inch arbor hole, and it is constructed from white aluminum oxide abrasive bonded in a vitrified matrix. At 46 grit with an I hardness code, this coarse-grade wheel delivers aggressive cutting action while the semi-friable grain structure promotes consistent self-sharpening during the grind cycle. The 38A series specification and non-porous construction make it a reliable choice for high-volume material removal applications in production and toolroom environments.

This wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production shop and toolroom settings. Its coarse 46 grit rating makes it most effective on softer workpiece materials where high removal rates are the priority. The vitrified bond holds up well under the heat and pressure generated during surface grinding operations, and the medium hardness rating resists premature glazing on the softer steel grades it is designed for. Licensed grinding machine operators and tool and die professionals are the primary installers of this wheel.

Key Features

• White aluminum oxide abrasive for consistent cut on soft carbon steels, tool steels, and super alloys
• Vitrified bond construction provides rigidity and stability at rated speeds
• Semi-friable grain promotes self-sharpening and reduces heat buildup
• 46 grit coarse grade for aggressive stock removal
• I hardness code with medium hardness rating resists glazing on softer workpieces
• Non-porous, non-tapered, no-recess Type 1 straight wheel geometry

Compatibility

Compatible with CNC cutting tool machines, cylindrical grinders, and surface grinders. Designed for grinding soft carbon steels, tool steels, and super alloys per the 38A Type 1 series specification.

Installation Notes

Grinding wheel mounting must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 requirements. Always ring-test the wheel before mounting and inspect for cracks or damage. Power down and lock out the grinding machine before changing wheels. Never exceed the maximum rated speed of 2485 RPM; confirm the machine spindle speed before mounting.
