3M 7000045991 Scotch-brite Unitized Metal Finishing Wheel 8 in

Product Description

The 3M 7000045991 Scotch-Brite MF-WL is a unitized metal finishing wheel designed for producing consistent brushed, satin, and mill finishes on metal surfaces. Built with convolute construction wound around a fiber core, this wheel delivers controlled abrasive cutting action while running cool and smooth. The open-web design resists loading, making it well-suited for extended finishing runs on stainless steel, brass, aluminum, and other metals. At 8 inches in diameter with a 3-inch arbor hole, it mounts to bench grinders and pedestal machines used in fabrication and finishing shops. Licensed trade professionals and skilled fabricators use this wheel for precision surface work.

This wheel is used in metalworking and fabrication applications where uniform surface finish is required. Common uses include blending and matching 3 or 4 mill finishes on stainless steel, as well as creating brushed or satin finishes on cutlery, appliance trim, builders hardware, and plumbing fixtures. Its high conformability makes it effective on irregular or contoured surfaces where flat abrasive tooling would leave uneven results. It is sold individually and intended for professional shop use.

Key Features

• Consistent cutting power produces superior satin, mill, and brushed finishes

Compatibility

Designed for use on bench grinders and pedestal finishing machines with a 3-inch arbor. Suitable for finishing stainless steel, brass, aluminum, and similar metals in fabrication and metalworking environments.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always ensure the machine is powered down and fully stopped before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the rated maximum speed of the wheel before operating. Use proper flanges and ensure the arbor bore fits securely before running the wheel.
