Norton 69014192779 Surface Grinding Wheel 220 Grit 6 in

Product Description

The NORTON 69014192779 is a Type 1A1 diamond surface grinding wheel engineered for wet finishing operations on hard and brittle materials. It measures 6 inches in diameter and 0.5 inches thick with a 1.25-inch arbor hole, making it a standard fit for surface grinders in tool rooms and precision machining environments. The wheel uses an Armored Synthetic Diamond (ASD) abrasive bonded in a resinoid matrix at a 75 concentration level, delivering consistent stock removal and surface finish at the 220 grit, Very Fine grade. Licensed HVAC, plumbing, and trades shops running carbide tooling or ceramic workpieces rely on this wheel for controlled, low-heat grinding passes.

This wheel is suited for wet surface grinding applications where a very fine finish is the goal. The resinoid bond responds well to dressing and maintains wheel integrity under flood coolant. Typical installations include precision surface grinders in industrial maintenance shops, tool and die operations, and trade contractor shops that sharpen or finish carbide-tipped tooling. The 0.25-inch superabrasive depth provides extended wheel life through multiple dressing cycles before the diamond layer is exhausted.

Key Features

• Type 1A1 flat wheel profile — no recess, no taper — for straightforward surface grinding setups
• Armored Synthetic Diamond (ASD) abrasive at 75 concentration for consistent cut rate and finish
• 220 grit Very Fine grade produces smooth surface finishes on carbide, ceramic, and hard tool steel
• Resinoid bond is dressable and performs reliably under wet coolant conditions
• Soft wheel hardness rating (R) allows the wheel to shed dull grains and self-sharpen during use
• 0.25-inch superabrasive depth extends usable wheel life through repeated dressing

Compatibility

Designed as an OEM-style replacement or direct-use wheel for surface grinders accepting a 6-inch diameter, 0.5-inch thick, Type 1A1 wheel with a 1.25-inch arbor hole. Specification code ASD220-R75B99-1/4 identifies the exact abrasive, bond, and concentration for cross-referencing with machine manufacturer recommendations.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or toolroom technician following ANSI B7.1 safety standards for abrasive wheels. Always power down and lockout the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and conduct a ring test per ANSI guidelines. Use appropriate flanges, blotters, and never exceed the wheel's rated maximum operating speed.
