Norton 69083159103 Surface Grinding Wheel 7in 46 Grit

Product Description

The NORTON 69083159103 is a Type 1 ceramic surface grinding wheel designed for precision material removal on ferrous metals and hard alloys. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole and a 46 grit coarse grade. The vitrified bond provides rigid support during wet grinding operations, making it well suited for high-stock-removal passes on difficult materials. Rated to 3600 RPM, this wheel is appropriate for use on CNC cutting tool machines, cylindrical grinders, and surface grinders. It is installed and operated by machinists and tool-room professionals working in metal fabrication and tooling environments.

This wheel is engineered for aggressive stock removal on demanding material groups including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The coarse 46 grit and medium hardness rating (code I) make it a practical choice for roughing operations where surface finish is secondary to material removal rate. Wet operation is specified, which helps manage heat and extend wheel life during sustained grinding cycles on hard-to-machine alloys.

Key Features

• Type 1 flat wheel geometry with no recess, suitable for standard surface and cylindrical grinder spindles
• Ceramic abrasive grain for consistent cut rate on hardened steels, titanium, and super alloys
• Vitrified bond delivers rigidity and form retention during precision grinding passes
• 46 grit coarse grade supports high stock removal on rough or scaled workpiece surfaces
• Rated to 3600 RPM for compatibility with common surface and cylindrical grinding machines
• Wet operation specified to dissipate heat and maintain workpiece integrity on heat-sensitive alloys

Compatibility

Designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders accepting a 1-1/4 inch arbor hole. Suitable for material applications including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by qualified machinists or tool-room personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always inspect the wheel for cracks or damage before mounting and conduct a ring test per ANSI procedures. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Blotters and proper flange sets must be used during installation to distribute clamping load evenly.
