3M 7000120809 Scotch-brite Mu-wl Finishing Wheel 8 Inch

Product Description

The 3M 7000120809 is a Scotch-Brite MU-WL convolute-constructed finishing wheel designed for cleaning and final finishing on stainless steel, aluminum, brass, copper, and other ferrous and non-ferrous metals. Built with silicon carbide mineral and a soft, open non-woven web construction, this wheel delivers a high degree of conformability with moderate aggressiveness. The lighter density allows controlled wear throughout the life of the wheel, producing consistent surface finishes on contoured, curved, and flat workpieces. It is used by metal fabricators, maintenance technicians, and finishing professionals who need repeatable results on sensitive or complex surfaces.

This wheel is suited for final finishing applications in fabrication shops, maintenance facilities, and light manufacturing environments. Its open web construction runs cool, making it appropriate for use on heat-sensitive base materials including thin-gauge stainless steel and non-ferrous alloys. The combination of mineral grades and soft density targets applications where a uniform grain finish is required without aggressive stock removal. It is installed on bench grinders or arbor-mount finishing machines that accept an 8-inch diameter wheel.

Key Features

• Convolute construction produces a balanced, smooth-running wheel throughout product life
• Silicon carbide mineral provides uniform grain for consistent final finishing results
• Highly conformable design handles contoured, curved, and irregular surfaces
• Open, non-woven web runs cool and reduces heat buildup on sensitive materials
• Moderate aggressiveness and lighter density deliver controlled, predictable wear
• Suitable for stainless steel, aluminum, brass, copper, and other metals

Compatibility

Designed for use on bench grinders and arbor-mount finishing machines that accept an 8-inch diameter convolute finishing wheel. Suitable for final finishing applications on stainless steel, ferrous metals, and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety requirements per ANSI B7.1 standards. Always power down and lock out the machine before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the maximum rated RPM marked on the wheel. Inspect the wheel for damage before each use and never operate a cracked or compromised wheel.
