Norton 69014192772 Diamond Grinding Wheel 320 Grit 6in

Product Description

The NORTON 69014192772 is a Type 1A1 diamond surface grinding wheel built for precision finishing work on hard and superhard materials. It features an Armored Synthetic Diamond (ASD) abrasive with a resinoid bond and a concentration rating of 75, delivering consistent material removal and surface quality at 320 grit. The wheel measures 6 inches in diameter, 1/4 inch thick, and carries a 1-1/4 inch arbor hole. Hardness is rated soft (code R), making it well-suited for controlled stock removal and fine surface finishing. This wheel is rated for both wet and dry operation and is used by grinding machinists and tool-and-die technicians working with carbide, ceramics, and other hard substrates.

This wheel is designed for surface grinding applications where an extra fine finish is required. The ASD abrasive series from Norton performs in finishing passes on flat surfaces, typically mounted on horizontal-spindle surface grinders. Its 320 grit rating targets final finishing and light stock removal rather than aggressive grinding. The 1/4 inch superabrasive depth matches the full wheel thickness, providing a consistent cutting face throughout the usable life of the wheel. This configuration suits tool rooms, carbide regrinding shops, and precision grinding operations handling tight surface finish specifications.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for consistent performance on hard materials
• 320 grit extra fine grade for precision surface finishing
• Resinoid bond with soft hardness rating (R) for controlled cutting action
• Superabrasive concentration of 75 for balanced wheel life and cut rate
• Rated for both wet and dry grinding operation
• Type 1A1 straight wheel profile with no recess and no taper

Compatibility

Designed as a direct-fit replacement or upgrade for Type 1A1 surface grinding wheels with a 6 inch diameter, 1/4 inch thickness, and 1-1/4 inch arbor hole on standard horizontal-spindle surface grinders accepting that arbor size.

Installation Notes

Diamond grinding wheels should be mounted and dressed by a qualified grinding machine operator or machinist. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and never exceed the rated maximum operating speed marked on the wheel. Follow ANSI B7.1 safety standards for the mounting, guarding, and operation of abrasive wheels.
