3M 7010330284 Silicon Carbide Unitized Wheel 3 in

Product Description

The 3M 7010330284 is a silicon carbide unitized wheel from the Standard Abrasives 500 Series, designed for light-pressure blending, finishing, and polishing on metallic and composite surfaces. Built with a soft, conformable density, this non-woven wheel delivers the finesse required when working to close tolerances. The open web construction resists loading, extending service life during sustained use. It measures 3 inches in diameter and is intended for use by machinists, fabricators, and metalworking professionals who need consistent surface finishing results without aggressive stock removal.

This wheel is suited for flat and contoured part finishing in both production and maintenance environments. It performs on ferrous metals, non-ferrous metals, exotic alloys including titanium, and composite materials, making it a versatile choice across aerospace, general fabrication, and precision metalworking applications. The wheel mounts via a unitized wheel mandrel, sold separately, and runs in both clockwise and counterclockwise directions for compatibility with a wider range of tools and machines.

Key Features

• Soft density silicon carbide abrasive for fine surface blending and finishing
• Conformable construction handles flat and contoured workpiece geometries
• Compatible with ferrous metals, non-ferrous metals, titanium, exotic alloys, and composites
• Bidirectional rotation — runs clockwise and counterclockwise
• Open web design resists loading and extends abrasive service life
• Center hole mount attaches to a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with standard unitized wheel mandrels. Suitable for light-pressure surface finishing operations on metalworking tools and bench or handheld machines that accept center-hole unitized wheels.

Installation Notes

Installation is performed by metalworking or fabrication professionals using a compatible unitized wheel mandrel. Ensure the tool is fully powered down and unplugged before mounting or removing the wheel. Verify the mandrel and spindle speed rating match the wheel specifications before operation. Follow the tool and abrasive manufacturer guidelines for maximum operating speed and safe work practices.
