Norton 66253044098 Surface Grinding Wheel 46 Grit 8 in

Product Description

The NORTON 66253044098 is a Type 1 surface grinding wheel designed for precision stock removal on hard ferrous metals and exotic alloys. Built with a ceramic abrasive grain and a vitrified bond, it operates at a maximum of 3105 RPM and delivers a coarse, aggressive cut rated at 46 grit with an I hardness code. The porous, semi-friable grain structure promotes cool cutting and self-sharpening action, which reduces heat buildup during extended grinding passes. At 3.14 pounds, this wheel is sized at 8 inches in diameter, 3/4 inches thick, with a 1-1/4 inch arbor hole. It is installed and dressed by grinding technicians and machine operators in production and tool-room environments.

This wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. Material compatibility includes 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is a strong choice in tool-and-die shops and production facilities where aggressive material removal on difficult alloys is required. The coarse grit level makes it appropriate for roughing operations rather than finish grinding passes.

Key Features

• Ceramic abrasive grain with vitrified bond for aggressive, consistent stock removal
• 46 grit, coarse grade — suited for roughing and heavy material removal
• Porous, semi-friable structure promotes cool cutting and extended wheel life
• Type 1 flat wheel profile with no recess — compatible with standard surface and cylindrical grinder spindles
• Maximum operating speed of 3105 RPM
• Compatible with a broad range of hard ferrous and exotic alloy workpiece materials

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Confirmed material applications include 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron.

Installation Notes

Mounting and dressing of grinding wheels should be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 general industry standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum rated RPM of 3105 stamped on the wheel blotter.
