3M 7100170631 Silicon Carbide Unitized Wheel 6 in

Product Description

The 3M 7100170631 is a silicon carbide unitized wheel in the Standard Abrasives 500 Series, designed for light-pressure surface finishing on flat and contoured workpieces. With a soft, conformable density, it delivers controlled material removal for blending, finishing, and polishing applications where tight tolerances matter. The open non-woven web construction resists loading, extending abrasive service life compared to conventional finishing wheels. At 6 inches in diameter and 3.69 inches wide, this wheel mounts via a unitized wheel mandrel and is suited for use by metalworking fabricators, tool and die technicians, and production finishing operators.

This wheel is built for ferrous and non-ferrous metals, including exotic alloys and titanium, as well as composite materials. It fits into finishing workflows where a consistent, fine surface profile is required without aggressive stock removal. Typical applications include deburring, light blending, and pre-inspection polishing on precision machined or formed parts. The wheel runs in both clockwise and counterclockwise directions, adding flexibility when matched to angle grinders, die grinders, or bench-mounted finishing machines. Operators working on aerospace, automotive, and general metal fabrication applications will find this wheel appropriate for close-tolerance surface finishing tasks.

Key Features

• Soft-density silicon carbide mineral for fine surface blending and polishing
• Conformable non-woven construction suits both flat and contoured part geometries
• Open web is load resistant, extending wheel service life
• Runs clockwise and counterclockwise for versatile tool pairing
• Compatible with ferrous metals, non-ferrous metals, exotic alloys, titanium, and composites
• Mounts using a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with unitized wheel mandrel arbors on angle grinders, die grinders, and bench-mounted finishing machines that accept 6-inch diameter non-woven unitized wheels.

Installation Notes

Installation should be performed by a qualified operator following the tool manufacturer's mounting instructions for unitized wheels. Always power down and disconnect the tool before mounting or removing the wheel. Confirm the spindle speed rating of the tool does not exceed the maximum rated RPM of the wheel before operation. Inspect the wheel for damage before each use and replace if any tears, unraveling, or deformation are present.
