Norton 66252836827 Surface Grinding Wheel 6in 100 Grit

Product Description

The NORTON 66252836827 is a Type 1 surface grinding wheel engineered for precision stock removal on a wide range of metallic and non-metallic materials. Built on a vitrified bond with a silicon carbide abrasive grain, this wheel delivers consistent cut rate and controlled surface finish at a fine 100-grit rating. The wheel measures 6 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. Rated at a maximum of 4140 RPM, it is suited for surface grinders, cylindrical grinders, and CNC cutting tool machines. The I hardness code indicates a medium-hard grade that resists loading while maintaining free cutting action on harder-to-grind alloys.

This wheel is designed for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, and copper, as well as gray iron, masonry, and natural stone. Its non-porous, non-tapered Type 1 flat profile makes it a direct fit for conventional surface grinder spindle setups in both production shop and maintenance environments. The green silicon carbide composition is particularly effective on non-ferrous metals and hard, brittle materials where aluminum oxide wheels tend to glaze or load prematurely.

Key Features

• Silicon carbide abrasive grain for effective cutting on non-ferrous metals, stainless, and masonry
• Vitrified bond provides rigidity, open structure, and resistance to heat buildup
• 100 grit fine grade produces controlled surface finish with consistent material removal
• I hardness (medium) resists glazing without sacrificing cutting efficiency
• Type 1 flat wheel profile with no recess — fits standard surface and cylindrical grinder arbors
• Maximum RPM of 4140 suitable for surface grinders and CNC tool machines

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. Series designation 39C Type 1; specification code 39C100-IVMT.

Installation Notes

Installation should be performed by a qualified machine operator or toolroom technician following ANSI B7.1 safe wheel handling and mounting standards. Always inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Power down and lockout the grinder before changing wheels, and confirm the machine spindle speed does not exceed the wheel maximum RPM rating of 4140. Use proper blotter flanges and a ring test to verify wheel integrity prior to running.
