Norton 69014192167 Diamond Surface Grinding Wheel 120 Grit

Product Description

The NORTON 69014192167 is a Type 1A1R diamond surface grinding wheel engineered for precision material removal on hard and brittle workpiece materials. The wheel measures 8 inches in diameter with a 5/8-inch arbor hole and a face thickness of 0.045 inches. It carries a 120-grit synthetic diamond abrasive at 100 concentration, bonded with a resinoid bond system and a hardness rating of R (Soft). The superabrasive depth is 1/4 inch, and the full specification designation is SD120-R100B99-1/4. This wheel is used in surface grinding operations where consistent stock removal and finish control are required on carbide, ceramic, glass, and similar hard materials.

This wheel is suited for surface grinding applications in tool and die shops, carbide tooling reconditioning, precision ceramics grinding, and production grinding environments. The Type 1A1R straight-cup profile makes it appropriate for use on reciprocating surface grinders and compatible rotary surface grinding machines. It is intended for professional machinists, tool grinders, and maintenance technicians working with superhard or brittle workpiece materials that standard aluminum oxide or silicon carbide wheels cannot effectively cut.

Key Features

• Synthetic diamond abrasive at 100 concentration for consistent, aggressive cutting action on hard materials
• Type 1A1R wheel form with 1/4-inch superabrasive depth for surface and face grinding operations
• 120-grit coarse grade for efficient stock removal in roughing or intermediate grinding passes
• Resinoid bond provides controlled wear rate and good finishing characteristics
• R hardness (Soft) rating reduces heat buildup and helps prevent workpiece damage on hard, brittle materials
• Full specification SD120-R100B99-1/4 for straightforward wheel-to-wheel replacement verification

Compatibility

Designed as an OEM-style replacement or direct specification match for surface grinding machines accepting an 8-inch diameter, 5/8-inch arbor hole, Type 1A1R diamond wheel.

Installation Notes

Diamond grinding wheels must be mounted and dressed only by qualified machinists or tool grinders following machine manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheel use. Inspect the wheel for cracks or damage before mounting and never exceed the rated maximum operating speed marked on the wheel. Power down and lockout the grinder before changing wheels, and use correct flanges and blotters as specified by the machine manufacturer. Do not use grinding fluids or coolants that are incompatible with resinoid bond systems.
