Norton 69014192310 Surface Grinding Wheel 150 Grit 12 in

Product Description

The NORTON 69014192310 is a Type 1A1 diamond surface grinding wheel designed for precision flat and surface grinding applications. It uses Armored Synthetic Diamond (ASD) abrasive bonded in a resinoid bond system, giving it consistent stock removal across both roughing and finishing passes. The wheel measures 12 inches in diameter and 0.5 inches thick with a 3-inch arbor hole and a 0.25-inch superabrasive depth. At 150 grit, it falls in the very fine grade range, making it well suited for tight-tolerance surface work where finish quality matters alongside material removal rate.

This wheel is intended for surface grinding operations on hard and brittle materials where diamond abrasive outperforms conventional wheels. It operates effectively under both wet and dry conditions, though wet grinding is generally preferred to extend wheel life and control heat at the workpiece. Machinists, tool and die technicians, and precision grinding shops are the primary users. The ASD designation indicates the diamond grains are armored, improving grain retention in the resinoid matrix and extending service intervals between wheel dressing cycles.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for extended grain retention in resinoid bond
• Type 1A1 straight wheel geometry for flat surface grinding
• 150 grit, very fine grade — suited for finishing passes with close dimensional tolerances
• Compatible with wet or dry grinding setups
• 0.25-inch superabrasive depth provides substantial usable wheel life
• Hardness code R (soft rating) helps the wheel self-dress on harder workpiece materials
• ASD series specification: ASD150-R75B99-1/4

Compatibility

Designed for use on surface grinders accepting a 12-inch diameter, Type 1A1 wheel with a 3-inch arbor hole. Verify spindle speed rating and arbor fit before mounting. No specific machine model compatibility was provided in product data.

Installation Notes

Mounting and dressing of precision grinding wheels should be performed by a qualified machinist or grinding technician following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test per standard procedure. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed marked on the wheel, and ensure flange diameter and clamping hardware are appropriate for a 3-inch arbor application.
