Norton 69936662083 Surface Grinding Wheel 46 Grit

Product Description

The NORTON 69936662083 is a Type 1 surface grinding wheel designed for precision stock removal on ferrous metals in wet or dry grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and long service life in surface, cylindrical, and CNC cutting tool machine setups. The wheel measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. At 46 grit with a J (medium) hardness rating and coarse grade, it is suited for aggressive material removal while maintaining wheel integrity at speeds up to 3600 RPM. Licensed grinding and machining professionals rely on this spec for toolroom and production surface grinding work.

This wheel is intended for use on hard carbon steels, soft carbon steels, and tool steels. It fits surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The 48A46-JVBE specification identifies the exact abrasive, grit, hardness, bond, and structure combination, allowing technicians to match replacement wheels with precision. The ruby aluminum oxide grain is a standard choice for ferrous toolroom applications where consistent finish and dimensional accuracy are required.

Key Features

• Aluminum oxide abrasive grain with vitrified bond for consistent cut and long wheel life
• 46 grit coarse grade suited for aggressive material removal on carbon and tool steels
• J hardness (medium) rating balances wheel breakdown rate with cutting efficiency
• Rated to 3600 RPM maximum operating speed
• Wet or dry operation compatible
• Type 1 flat wheel with no recess, non-porous structure

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding hard carbon steels, soft carbon steels, and tool steels. Arbor hole size of 1-1/4 inches is a common standard fit for bench and production surface grinding equipment.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or grinding equipment operator following ANSI B11.9 safety standards and the machine manufacturer's mounting instructions. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting, and conduct a ring test as outlined in ANSI B7.1. Never exceed the 3600 RPM maximum rated speed marked on the wheel or packaging.
