Norton 69014192777 Diamond Surface Grinding Wheel 120 Grit

Product Description

The NORTON 69014192777 is a Type 1A1 diamond surface grinding wheel designed for precision material removal in industrial and trade grinding applications. Built with Armored Synthetic Diamond (ASD) abrasive and a resinoid bond, this wheel operates at a fine 120 grit to deliver controlled stock removal during roughing and cut-off operations. The wheel measures 6 inches in diameter, 0.5 inches thick, with a 1-1/4 inch arbor hole and a 1/4 inch superabrasive depth. Rated soft (hardness code R) with a 75 concentration, it suits applications where consistent finish and wheel wear are priorities. Weight is 1.5 pounds.

This wheel is suited for surface grinding operations on hard and brittle materials where diamond abrasive outperforms conventional aluminum oxide or silicon carbide wheels. It is compatible with both wet and dry operation, though wet use is recommended to extend wheel life and control heat at the workpiece. Typical install scenarios include surface grinders used in tool and die shops, carbide tooling regrind operations, and ceramic or glass material processing. The no-recess, non-tapered Type 1A1 profile fits standard surface grinder spindle configurations with a 1-1/4 inch bore.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for long-lasting performance on hard materials
• 120 grit fine grade for controlled stock removal and consistent surface finish
• Resinoid bond provides resilience and smooth cutting action
• Wet and dry operation supported; wet use extends wheel life
• Soft hardness rating (R) with 75 concentration for efficient material release
• No recess, non-tapered Type 1A1 profile for broad surface grinder compatibility

Compatibility

Designed as an OEM-style replacement or direct specification match for surface grinders accepting a Type 1A1 wheel with a 1-1/4 inch arbor bore. Specification code ASD120-R75B99-1/4 identifies this wheel within the Norton ASD series for procurement and cross-reference purposes.

Installation Notes

Installation should be performed by a qualified grinding machine operator or maintenance technician following the grinder manufacturer's wheel mounting procedures. Always power down and de-energize the machine before mounting or dismounting the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Never exceed the maximum RPM rating of the machine spindle for the wheel diameter in use.
