Norton 66253160782 Surface Grinding Wheel 80 Grit

Product Description

The NORTON 66253160782 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous and non-ferrous materials in industrial grinding applications. The wheel measures 10 inches in diameter and 1 inch thick, with a 3-inch arbor hole, and runs at a maximum of 2485 RPM. It uses an aluminum oxide abrasive grain bonded in a vitrified matrix, rated at 80 grit with a K hardness code and medium grade. Licensed HVAC, machining, and toolroom professionals recognize vitrified bond wheels for their rigidity and free-cutting action across a wide range of surface grinding work.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. It is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure of the 32A series promotes chip clearance and cooler cutting, making it appropriate for both production and precision toolroom environments where surface finish and dimensional control are priorities.

Key Features

• Aluminum oxide abrasive grain with vitrified bond for rigid, free-cutting performance
• 80 grit, K hardness (medium grade) for balanced stock removal and surface finish
• Porous wheel structure promotes chip evacuation and reduces heat buildup
• Type 1 straight wheel profile with no recess, compatible with standard surface grinder spindles
• Rated for use on a broad material range including stainless, carbon steels, tool steels, aluminum, and cast iron
• Specification designation 32A80-KVBE for direct cross-reference and reorder

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or toolroom technician following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the spindle speed does not exceed the 2485 RPM maximum marked on the wheel. Never exceed the rated RPM under any circumstance, and use proper flanges and blotters as specified by the grinder manufacturer.
