Norton 69014192063 Diamond Grinding Wheel 4in 180 Grit

Product Description

The NORTON 69014192063 is a Type 1A1R diamond surface grinding wheel designed for precision material removal on hard and brittle workpiece materials. Built on a metal bond system with Armored Synthetic Diamond (ASD) abrasive, it delivers consistent cut rates and extended wheel life compared to conventional abrasive wheels. The wheel measures 4 inches in diameter with a 0.012-inch thickness and a 1/2-inch arbor hole. At 180 grit with a medium hardness rating (Hardness Code N), it suits finishing and semi-finishing operations where surface quality and dimensional control matter. Machinists and tool-and-die professionals install this wheel on surface grinders for flat-surface work on ceramics, carbide, glass, and similarly hard materials.

This wheel is suited for surface grinding applications in toolrooms, production shops, and maintenance environments. The Type 1A1R form factor is a standard straight wheel profile used on horizontal-spindle surface grinders. The 1/8-inch superabrasive depth and 75 concentration rating make it appropriate for moderate material removal with controlled heat generation. It is a single-unit item with no minimum order quantity beyond one piece.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for hard and brittle material grinding
• Metal bond construction for long wheel life and shape retention during aggressive cuts
• 180 grit, medium grade for semi-finishing and finishing surface passes
• Type 1A1R straight wheel profile compatible with horizontal-spindle surface grinders
• 1/8-inch superabrasive depth with 75 concentration for balanced cut rate and wheel longevity
• Specification code M4D180-N75M99-1/8 for direct cross-reference and reorder

Compatibility

Designed for use on horizontal-spindle surface grinders accepting a 4-inch diameter, 1/2-inch arbor hole, Type 1A1R straight grinding wheel. Verify spindle speed rating against machine RPM specifications before mounting.

Installation Notes

Installation should be performed by a qualified machinist or grinding specialist following ANSI B7.1 safety standards for abrasive wheel use. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test if applicable. Never exceed the maximum operating speed marked on the wheel or packaging.
