Norton 69014192210 Surface Grinding Wheel 7in 100 Grit

Product Description

The NORTON 69014192210 is a Type 1A1 diamond surface grinding wheel built for precision material removal on hard and brittle workpiece materials. It measures 7 inches in diameter, 1/4 inches thick, with a 1-1/4 inches arbor hole and a 1/4 inches superabrasive depth. The abrasive is synthetic diamond (SD) bonded in a resinoid matrix with a 100 concentration, producing consistent stock removal and a fine surface finish. Rated at 100 grit with an R (soft) hardness code, this wheel is suited for wet grinding operations in roughing applications. Grinding wheel fabricators, tool and die shops, and industrial maintenance techs are the primary installers.

This wheel is designed for surface grinding machines configured for wet operation. The Type 1A1 flat wheel profile with no recess and no taper makes it compatible with standard surface grinder spindle setups. It is well suited for roughing passes on carbide, ceramics, glass, and other hard or superhard materials where a conventional abrasive wheel would wear prematurely. The 100 grit designation delivers aggressive stock removal while still maintaining a fine grade finish rating for controlled dimensional work.

Key Features

• Synthetic diamond (SD) abrasive for extended wheel life on hard materials
• Resinoid bond provides controlled cut rate and cool grinding action
• 100 grit fine grade for aggressive roughing with consistent surface quality
• Type 1A1 flat profile with no recess and no taper for straightforward mounting
• Wet operation rated — designed to run with coolant for heat management
• Soft hardness rating (R) helps the wheel self-dress and expose fresh abrasive

Compatibility

Designed as an OEM-style replacement or direct-fitment superabrasive wheel for surface grinding machines accepting a 7 inch diameter, 1-1/4 inch arbor hole Type 1A1 wheel. Specification code SD100S-R100B99-1/4 per Norton Diamond Series standards.

Installation Notes

Surface grinding wheels must be installed by qualified personnel following applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per manufacturer guidelines. Never exceed the maximum operating speed marked on the wheel, and confirm the machine spindle speed is within the rated RPM before starting.
