Norton 69936662920 Surface Grinding Wheel 7in 60 Grit

Product Description

The NORTON 69936662920 is a Type 1 surface grinding wheel built for precision flat-surface grinding on metalworking equipment. It measures 7 inches in diameter, 1/2 inch thick, with a 1-1/4 inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, rated at a J hardness code and medium grade. It carries a maximum operating speed of 3600 RPM. The 25A60-JVBE specification designation confirms grit, hardness, bond, and structure at a glance for experienced toolroom and machine shop personnel. This wheel supports both wet and dry grinding operations.

This wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well suited to grinding soft carbon steels, tool steels, and super alloys. The aluminum oxide grain with vitrified bond delivers consistent stock removal and a predictable wear rate across production and toolroom environments. The pink wheel color and semi-friable grain structure are characteristic of the NORTON 25A series, which is commonly specified for precision tool grinding and surface finishing applications.

Key Features

• Aluminum oxide abrasive, semi-friable grain for controlled stock removal on ferrous metals
• Vitrified bond for rigidity, open structure, and coolant compatibility
• J hardness (medium grade) balances wheel life with consistent cut rate
• Rated to 3600 RPM maximum operating speed
• Supports both wet and dry grinding operation
• No recess, no taper — standard Type 1 flat wheel geometry

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for material applications including soft carbon steels, tool steels, and super alloys per the NORTON 25A Type 1 series specification.

Installation Notes

Grinding wheel installation and dressing must be performed by qualified personnel following ANSI B11.9 and OSHA 29 CFR 1910.215 safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before mounting or removing the wheel. Never exceed the 3600 RPM maximum rated speed marked on the wheel.
