Norton 66252911685 Surface Grinding Wheel 120 Grit 7in

Product Description

The NORTON 66252911685 is a Type 1 surface grinding wheel designed for precision stock removal and finish grinding on a range of ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability under repeated use. It measures 7 inches in diameter, 1/4 inch thick, and carries a 1-1/4 inch arbor hole. The fine grade, 120 grit specification suits finish grinding passes where surface quality matters. Rated to 3600 RPM, it is sized for bench-top and floor-model surface grinders used in production and toolroom environments.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, gray-bodied wheel carries a hardness code of L, placing it in the medium hardness range, which balances wheel life against free-cutting behavior on a broad range of workpiece materials. It is a practical choice for toolroom technicians and production grinding operators who need reliable consistency across varied material applications.

Key Features

• Aluminum oxide abrasive with vitrified bond for controlled, consistent material removal
• 120 grit, fine grade for finish grinding and close-tolerance surface work
• Hardness code L (medium) balances wheel life with cutting efficiency
• Porous structure aids coolant flow and reduces heat buildup at the grinding interface
• 3600 RPM maximum operating speed
• Type 1 flat wheel profile, no recess, no taper — direct drop-in for standard arbor setups
• Series designation 32A120-LVBE for specification-driven procurement

Compatibility

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

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified personnel following ANSI B11.9 and applicable shop safety standards. Always inspect the wheel for cracks or chips before mounting — do not use a damaged wheel. Power down and lockout the grinder before changing wheels. Verify the machine spindle speed does not exceed the 3600 RPM maximum marked on the wheel, and use the correct flange and blotter assembly for the 1-1/4 inch arbor bore.
