Norton 69014192157 Diamond Surface Grinding Wheel 6in 220 Grit

Product Description

The NORTON 69014192157 is a Type 1A1R diamond surface grinding wheel designed for precision material removal on hard and brittle workpiece materials. It measures 6 inches in diameter with a 1.25 inch hole size and a thin 0.035 inch wheel thickness. The abrasive material is synthetic diamond (SD) bonded in a resinoid bond matrix at 100 concentration, rated Fine grade with a hardness code of R (Soft). This wheel is built for controlled, accurate stock removal in surface grinding applications and is installed and operated by machinists, tool and die makers, and skilled fabricators working with carbide, ceramics, glass, or hardened steel.

This wheel fits surface grinding operations where a fine finish and consistent material removal rate are required on hard substrates. The 1A1R wheel form is a standard straight wheel profile commonly used on horizontal spindle surface grinders. The superabrasive depth of 0.25 inches provides extended service life across repeated dressing cycles. Typical applications include grinding tungsten carbide tooling, ceramic components, and other materials that exceed the effective range of conventional abrasive wheels. The specification designation for this wheel is SD220-R100B99-1/4.

Key Features

• Synthetic diamond abrasive at 100 concentration for consistent cut rate on hard materials
• Type 1A1R straight wheel form compatible with standard horizontal spindle surface grinders
• Fine 220 grit for precision finish grinding applications
• Resinoid bond provides controlled wheel hardness and improved surface finish quality
• 0.25 inch superabrasive depth delivers extended usable wheel life
• Thin 0.035 inch wheel thickness minimizes heat generation and material waste

Compatibility

Designed as a replacement or production-use surface grinding wheel for horizontal spindle surface grinders accepting a 6 inch diameter, 1.25 inch hole, Type 1A1R wheel configuration.

Installation Notes

Superabrasive grinding wheels must be mounted and operated by qualified machinists or grinding specialists following ANSI B7.1 safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and verify that the machine spindle speed does not exceed the maximum operating speed marked on the wheel. Never use wheel flanges that are smaller than required for the wheel diameter.
