Norton 66252835500 Surface Grinding Wheel 60 Grit 6 in

Product Description

The NORTON 66252835500 is a Type 1 surface grinding wheel designed for precision flat-surface stock removal on a wide range of metals. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and good form-holding under wet grinding conditions. The wheel measures 6 inches in diameter by 1/8 inches thick with a 1-1/4 inches arbor hole, and is rated to a maximum of 4140 RPM. Hardness code K places it in the medium grade range, making it well suited for controlled material removal without excessive wheel breakdown. Weighing 0.42 pounds, it is a direct fit for standard surface grinder spindles used daily in machine shops and tool rooms.

This wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is rated for wet operation, which helps control heat buildup and extends wheel life during extended grinding passes. Typical applications include finish and roughing work on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a standard production wheel for machine shops, maintenance facilities, and tooling departments that require repeatable surface finishes on ferrous and non-ferrous workpieces.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent cut rate and form retention
• Medium grade (hardness code K) balances wheel life against stock removal rate
• Rated for wet grinding operation to manage heat and extend service life
• Non-porous, non-tapered, no-recess Type 1 profile for standard surface and cylindrical grinder spindles
• Broad material compatibility: stainless, carbon steels, tool steels, aluminum, and cast and ductile iron
• Series specification 32A60-KVBE for cross-reference and replacement identification

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 Series Stainless, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Installation should be performed by a qualified machinist or grinding machine operator following the machine manufacturer's spindle and arbor specifications. Always power down and lock out the grinding machine before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and perform a ring test per ANSI B7.1 guidelines. Never exceed the 4140 RPM maximum speed rating marked on the wheel.
