3M 7000121887 Unitized Abrasive Wheel Silicon Carbide 3 in

Product Description

The 3M 7000121887 is a silicon carbide unitized abrasive wheel from the Standard Abrasives 500 Series, designed for light-pressure blending, finishing, and polishing on metal and composite surfaces. At 3 inches in diameter, this non-woven wheel features a soft, conformable density that lets it follow flat or contoured part geometry without removing excess material. Licensed trades workers in metalworking, fabrication, and maintenance use this wheel when close tolerances demand finesse over aggression. The open web construction resists loading, extending usable service life across repeated passes.

This wheel is suited for use on ferrous metals, non-ferrous metals, exotic alloys including titanium, and composite materials. It performs well in light finishing and surface preparation tasks where blending to a fine finish is the goal. The 500 Series density positions it between buff-and-blend softness and more aggressive non-woven products, making it a practical choice for controlled stock removal on precision parts in fabrication shops and industrial maintenance environments.

Key Features

• Soft silicon carbide density conforms to flat and contoured surfaces for precise finishing
• Open web construction resists loading and extends abrasive service life
• Runs clockwise and counterclockwise for greater versatility with tools and machines
• Compatible with ferrous metals, non-ferrous metals, titanium, exotic alloys, and composites
• Cuts faster than buff-and-blend non-woven products while maintaining surface control
• Attaches to a unitized wheel mandrel, sold separately

Compatibility

Designed for use with a standard unitized wheel mandrel (sold separately). Suitable for angle grinders, bench grinders, and similar rotary tools that accept center-hole unitized wheels in the 3-inch diameter range.

Installation Notes

Installation is typically performed by metalworking technicians or maintenance trades. Power down and de-energize the tool completely before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the rated RPM of the wheel before operation. Always use the appropriate unitized wheel mandrel and follow the tool and accessory manufacturer guidelines for secure attachment.
