Norton 69014192069 Diamond Surface Grinding Wheel 150 Grit

Product Description

The NORTON 69014192069 is a Type 1A1R diamond surface grinding wheel designed for precision flat grinding applications. At 5 inches in diameter with a 1/2 inch arbor hole and a thin 0.015 inch wheel thickness, this wheel delivers controlled material removal on hard and brittle workpiece materials. The abrasive is Armored Synthetic Diamond (ASD) with a 100 concentration, bonded in a metal bond matrix at a medium grade (hardness code N). Specification code M4D150-N100M99-1/8 identifies the exact abrasive formulation. This wheel is installed and operated by tool-and-die makers, precision grinders, and machining professionals working with carbide, ceramics, glass, or similar hard materials.

The 69014192069 is suited for surface grinding operations on horizontal-spindle surface grinders where a thin, flat-profile wheel is required. The 1/8 inch superabrasive depth provides extended service life in production and toolroom environments. Its medium grade and 150 grit make it appropriate for semi-finish to finish grinding passes where tight dimensional tolerances and smooth surface finish are the target. This wheel is not intended for freehand or angle-grinder use and must be mounted on a machine rated for its diameter and operating speed.

Key Features

• Type 1A1R flat wheel profile for surface grinding applications
• 150 grit Armored Synthetic Diamond (ASD) abrasive for hard and brittle materials
• Metal bond matrix provides durability and form retention under coolant
• Medium grade (hardness code N) with 100 abrasive concentration
• 1/8 inch superabrasive depth for extended wheel life
• Thin 0.015 inch wheel thickness enables precise, low-force stock removal

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for horizontal-spindle surface grinders accepting a 5 inch diameter, 1/2 inch arbor hole, Type 1A1R wheel configuration.

Installation Notes

Diamond grinding wheels must be mounted by qualified personnel following machine manufacturer guidelines and applicable ANSI B7.1 safety standards. Confirm the machine spindle speed does not exceed the wheel's rated maximum operating speed before mounting. Inspect the wheel for cracks or damage before installation and use the correct flanges and blotters as specified by the wheel and machine manufacturer. Always dress the wheel after mounting and before the first grind pass to ensure true running and proper abrasive exposure.
