Norton 66253246869 Surface Grinding Wheel 46 Grit 14in

Product Description

The NORTON 66253246869 is a Type 5 recessed surface grinding wheel designed for use on surface grinders and cylindrical grinders in metalworking and fabrication environments. Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal on a wide range of ferrous and non-ferrous metals. The wheel measures 14 inches in diameter and 1.5 inches thick with a 5-inch arbor hole, a one-side recess depth of 0.5 inches, and a recess diameter of 8 inches. Rated at a maximum of 2,320 RPM, it carries a coarse 46 grit and I hardness code, placing it in the medium hardness range. Machinists, tool and die shops, and industrial grinding operations are the primary installers and users of this wheel.

This grinding wheel is suited for heavy stock removal and surface finishing operations on a broad range of materials. Typical applications include surface grinding and cylindrical grinding on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It fits surface grinders and cylindrical grinders equipped with a 5-inch arbor and is appropriate for both production shop environments and maintenance grinding tasks where a coarse, aggressive cut is required.

Key Features

• Aluminum oxide abrasive with vitrified bond for consistent, controlled material removal
• Coarse 46 grit and I hardness code for aggressive stock removal on hard and soft metals
• Type 5 recessed wheel profile with one-side recess for proper fitment on compatible spindle assemblies
• Maximum operating speed of 2,320 RPM — verify machine speed before mounting
• Non-porous construction for stable, repeatable performance across ferrous and non-ferrous applications
• Blue and gray wheel color consistent with NORTON 32A series identification

Compatibility

Designed for use with surface grinders and cylindrical grinders. Compatible material applications include 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, and Gray Iron. Requires a machine with a 5-inch arbor hole and a spindle speed at or below 2,320 RPM.

Installation Notes

Grinding wheel mounting and dressing must be performed by qualified personnel familiar with ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always power down and lock out the grinder before installing or changing wheels. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Do not exceed the maximum operating speed of 2,320 RPM stamped on the wheel.
