Norton 69083159107 Surface Grinding Wheel 8in 46 Grit

Product Description

The NORTON 69083159107 is a Type 1 ceramic surface grinding wheel engineered for aggressive stock removal on hard ferrous metals and specialty alloys. Measuring 8 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, this wheel carries a 46-grit coarse grade and an I hardness code, making it well-suited for applications that demand fast cutting action with controlled wheel wear. The vitrified bond provides rigidity and free-cutting characteristics. Maximum operating speed is rated at 3105 RPM. The wheel is non-porous and non-tapered with a standard flat profile and no recess. Machinists, tool-and-die makers, and grinding technicians install this wheel in production and maintenance grinding operations.

This grinding wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its coarse 46-grit ceramic abrasive is optimized for material removal on 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The Series 5NQ Type 1 designation identifies the wheel geometry and bond specification, allowing direct specification against print or purchase order requirements. It is a practical choice for tool rooms and production floor grinding cells handling a range of difficult-to-grind ferrous and exotic materials.

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a Type 1 wheel with a 1-1/4 inch arbor hole. Suitable for grinding 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron workpieces.

Installation Notes

Installation and wheel changes must be performed by a qualified grinding machine operator or machinist following ANSI B7.1 safe use standards. Always power down and lockout/tagout the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the 3105 RPM maximum speed rating stamped on the wheel or blotter. Flanges, blotters, and arbor hardware must be in clean, serviceable condition before mounting.
