Norton 69014192773 Diamond Surface Grinding Wheel 120 Grit

Product Description

The NORTON 69014192773 is a Type 1A1 diamond surface grinding wheel designed for precision flat and surface grinding applications. Built with Armored Synthetic Diamond (ASD) abrasive and a resinoid bond, this wheel delivers consistent stock removal on hard and brittle materials. At 6 inches in diameter and 3/8 inches thick with a 1-1/4 inches arbor hole, it mounts to standard surface grinders. The 120 grit, fine grade specification suits finishing and light roughing passes. Wet operation is recommended to control heat and extend wheel life. The ASD120-R75B99-1/4 specification identifies abrasive type, hardness, concentration, bond, and superabrasive depth.

This wheel is suited for surface grinding operations on ceramics, carbide tooling, glass, ferrite, and similar hard or brittle materials in toolroom, maintenance, and production environments. The 1/4 inch superabrasive depth and 75 concentration rating make it appropriate for both roughing and cut-off material applications. It is typically used in toolroom and industrial settings where consistent surface finish and dimensional accuracy are required.

Key Features

• Armored Synthetic Diamond (ASD) abrasive for grinding hard, brittle materials
• Resinoid bond provides controlled cut rate and good surface finish
• 120 grit fine grade for finishing and light material removal
• Type 1A1 straight wheel geometry with no recess for flat surface grinding
• Wet operation rating helps manage heat buildup and prolong wheel life
• Superabrasive concentration of 75 and depth of 1/4 inch for balanced performance

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for surface grinders accepting a 6 inch diameter, 3/8 inch thick, Type 1A1 straight wheel with a 1-1/4 inch arbor hole.

Installation Notes

Diamond grinding wheels must be installed and operated by qualified machinists or tool and die technicians following ANSI B11 and OSHA abrasive wheel standards. Before mounting, inspect the wheel for cracks or chips and perform a ring test. Power down and lock out the grinder before changing wheels, and confirm the spindle speed does not exceed the wheel's maximum rated RPM. Wet operation is specified for this wheel — ensure coolant flow is established before grinding begins.
