Norton 66252940899 Surface Grinding Wheel 80 Grit 7in

Product Description

The NORTON 66252940899 is a Type 1 straight surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and stable performance across a range of grinding applications. It measures 7 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 80 grit, medium-grade specification and K hardness rating make it well suited for controlled material removal without excessive wheel wear. Rated to 3600 RPM, it is a standard fit for surface grinder spindles in production and tool room environments.

This wheel is suited for surface grinding operations 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 vitrified bond and porous structure support free cutting action and efficient swarf clearance, making this wheel appropriate for both light finishing passes and more aggressive material removal cycles in shop environments.

Key Features

• Aluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, tool steels, and cast iron
• Vitrified bond with porous structure for free cutting action and efficient swarf clearance
• 80 grit, medium grade, K hardness rating for controlled stock removal
• Type 1 straight wheel, no recess, gray color — standard geometry for surface and cylindrical grinders
• 3600 RPM maximum operating speed
• Series designation 32A80-KVBE for direct specification matching

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 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 grinding machine operator or machinist following applicable ANSI B11 and OSHA grinding wheel safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the machine before changing wheels. Never exceed the maximum RPM rating marked on the wheel.
