Norton 69936662919 Surface Grinding Wheel 60 Grit 7 in

Product Description

The NORTON 69936662919 is a Type 1 surface grinding wheel engineered for precision stock removal on ferrous metals and high-performance alloys. Built on an aluminum oxide abrasive with a vitrified bond, this 7-inch diameter, 0.5-inch thick wheel carries a 60-grit, medium-grade cutting structure rated for operation up to 3600 RPM. The 1.25-inch arbor hole fits standard surface and cylindrical grinder spindles. The semi-friable grain structure continuously fractures to expose fresh cutting edges, maintaining consistent cut rates through the wheel life. Suited for licensed machinists and tool-and-die shops running wet or dry grinding cycles.

This wheel is designed for use on soft carbon steels, tool steels, and super alloys in both wet and dry operating conditions. Typical applications include flat surface grinding on horizontal-spindle machines, cylindrical grinding passes, and CNC cutting tool reconditioning. The pink aluminum oxide grain is well matched to materials that demand a balance of cut rate and surface finish control. No recess geometry means flat mounting directly to the machine flange without adapter complications.

Key Features

• Aluminum oxide abrasive with vitrified bond for rigid, consistent material removal
• 60-grit medium grade delivers a balance of fast stock removal and acceptable surface finish
• Semi-friable grain self-sharpens during use, extending effective wheel life
• Rated to 3600 RPM maximum operating speed
• Supports both wet and dry grinding operations
• Type 1 flat wheel with no recess, 1.25-inch arbor hole for standard spindle fitment

Compatibility

Designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding soft carbon steels, tool steels, and super alloys.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator following ANSI B7.1 safety standards for abrasive wheel use. Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to installation. Power down and lock out the grinder before changing wheels, and verify the machine spindle speed does not exceed the 3600 RPM maximum rating marked on the wheel. Use proper flanges and a blotter on each side of the wheel during mounting.
