Norton 69014192151 Diamond Surface Grinding Wheel 100 Grit

Product Description

The NORTON 69014192151 is a Type 1A1R diamond surface grinding wheel engineered for precision flat grinding of hard and brittle materials. Built with a synthetic diamond (SD) abrasive and a resinoid bond, this wheel delivers controlled stock removal with a coarse grade rating suitable for aggressive material contact. The wheel measures 4 inches in diameter, 1/32 inch thick, with a 3/4 inch hole size and a 1/4 inch superabrasive depth. At 0.56 pounds, it is lightweight for its class. The specification designation SD100S-R100B99-1/4 confirms 100 grit, 100 concentration synthetic diamond abrasive, and soft hardness (code R), making it appropriate for demanding precision grinding applications.

This wheel is used in surface grinding operations where tight tolerances and clean surface finishes are required on hard substrates such as carbide, ceramics, glass, and hardened tool steels. The Type 1A1R profile is a standard straight wheel configuration suited for surface grinders in tool rooms, machine shops, and manufacturing environments. Installation and operation are typically performed by machinists and tool grinders working with horizontal or vertical spindle surface grinding equipment.

Key Features

• Synthetic diamond (SD) abrasive for effective grinding of carbide, ceramics, and other superhard materials
• Type 1A1R straight wheel profile for surface grinding applications
• 100 grit coarse grade for aggressive stock removal
• Resinoid bond with soft hardness rating (code R) for consistent wheel breakdown and free cutting action
• 100 concentration superabrasive for uniform abrasive distribution across the 1/4 inch superabrasive depth
• Lightweight at 0.56 pounds for reduced spindle load

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for surface grinders accepting a 4 inch diameter, 3/4 inch arbor hole, Type 1A1R straight wheel configuration.

Installation Notes

Grinding wheel installation and dressing should be performed by qualified machinists following ANSI B11.9 safety standards for grinding machines. Always inspect the wheel for cracks or chips before mounting and perform a ring test per applicable safety guidelines. Power down and lock out the surface grinder before changing the wheel. Never exceed the wheel's rated maximum operating speed, and always use appropriate flanges and a blotter washer where required.
