3M 7000120664 Scotch-brite Mu-wl 12 Inch Finishing Wheel

Product Description

The 3M 7000120664 Scotch-Brite MU-WL Multi-Finishing Wheel is a convolute-constructed abrasive wheel designed for cleaning and final finishing on stainless steel, aluminum, brass, copper, and other metals. Built with silicon carbide mineral and a soft, open non-woven web construction, it delivers controlled, uniform material removal without generating excessive heat. At 12 inches in diameter and 2.6 inches wide, this wheel suits bench grinder and pedestal grinder setups used in metal fabrication, maintenance, and finishing shops. Metalworkers and fabricators install it where high conformability and lighter abrasive density are required for consistent final finishing results.

This wheel is intended for final finishing applications on both ferrous and non-ferrous metals. The combination of mixed mineral grades and lower web density makes it well suited for contoured, curved, and irregular surfaces where a standard grinding wheel would remove too much material or leave an uneven finish. Typical use cases include weld blending, surface prep, and cosmetic finishing on stainless steel components, aluminum extrusions, and brass or copper fittings. It is commonly used in fabrication shops, maintenance facilities, and light manufacturing environments.

Key Features

• Convolute construction delivers a balanced, smooth-running wheel throughout its service life
• Open, non-woven web runs cool and reduces heat buildup on heat-sensitive base materials
• Highly conformable design maintains consistent contact on contoured and curved surfaces
• Moderate aggressiveness with lighter density provides controlled wear and repeatable results
• Silicon carbide mineral provides uniform grain for finishing on stainless steel, ferrous, and non-ferrous metals

Compatibility

Designed as an OEM-style replacement or direct-fit finishing wheel for bench grinders and pedestal grinders accepting 12-inch diameter convolute abrasive wheels.

Installation Notes

Installation is typically performed by a metalworker, fabricator, or maintenance technician. Disconnect and lock out the grinder from its power source before mounting or removing the wheel. Ensure the arbor size and RPM rating of the machine match the wheel specifications before operation. Always install the proper guarding and use appropriate personal protective equipment including eye and face protection when operating abrasive wheels.
