Norton 69014192159 Diamond Surface Grinding Wheel 6in 120G

Product Description

The NORTON 69014192159 is a Type 1A1R diamond surface grinding wheel designed for precision surface grinding operations. The wheel measures 6 inches in diameter and 0.05 inches thick, with a 1-1/4 inch arbor hole for secure spindle mounting. It carries a 120 grit Armored Synthetic Diamond (ASD) abrasive in a resinoid bond with a coarse grade and R hardness rating. The superabrasive layer runs 1/4 inch deep at 100 concentration, per specification ASD120-R100B99-1/4. This wheel is used by toolroom machinists, surface grinder operators, and tool-and-die professionals who require consistent stock removal and controlled finishes on hard or brittle materials.

Type 1A1R wheels are commonly applied in surface grinding of carbide tooling, ceramics, hardened steels, and composite materials. The thin-rim diamond configuration allows for efficient cutting action with reduced heat generation at the workpiece. This wheel is suited to horizontal spindle surface grinders in both production and toolroom environments where tight tolerances and repeatable results are required.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for long wheel life on hard and abrasive materials
• Type 1A1R thin-rim profile optimized for surface grinding applications
• Resinoid bond provides controlled cut rate and resistance to shock loading
• 120 grit coarse grade delivers aggressive stock removal
• 1/4 inch superabrasive depth at 100 concentration for extended service life
• Specification ASD120-R100B99-1/4 for direct technical cross-reference

Compatibility

Designed for use on horizontal spindle surface grinders accepting a 6 inch diameter wheel with a 1-1/4 inch arbor bore. Verify spindle speed rating against the wheel's maximum operating RPM before mounting.

Installation Notes

Installation should be performed by a qualified grinding machine operator following applicable ANSI B7.1 safety standards for grinding wheel mounting and use. Power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips prior to mounting, and always perform a ring test on vitrified wheels — note this wheel uses a resinoid bond, so follow the manufacturer's inspection procedure for bonded abrasives. Run the wheel at operating speed with the guard in place for at least one minute before presenting it to the workpiece.
