3M 7000045890 Scotch-brite Unitized Metal Finishing Wheel 6 in

Product Description

The 3M 7000045890 Scotch-Brite MF-WL is a unitized metal finishing wheel designed for surface finishing and blending work on metal components. Built on a convolute construction wound around a fiber core, the wheel delivers consistent abrasive cutting action across the full face of the wheel. It measures 6 inches in diameter and mounts on a 1-inch arbor, making it compatible with standard bench grinders and pedestal-mounted finishing machines. At 1.09 pounds, it is suited for stationary machine use by metalworkers, fabricators, and finishing technicians who need repeatable satin, brushed, or mill-matched surface finishes on stainless steel and other metals.

This wheel is used in metal fabrication and finishing shops for blending and matching 3 or 4 mill finishes on stainless steel, creating brushed or satin finishes on cutlery, appliance trim, builders hardware, and plumbing fixtures. Its open-web construction and high conformability make it effective on irregular or contoured surfaces where flat abrasive media would skip or gouge. It performs on stainless steel, brass, aluminum, and other non-ferrous and ferrous metals.

Key Features

• Convolute construction wound around a fiber core runs smooth for fine, uniform finishing
• Open-web construction resists loading and dissipates heat to reduce workpiece discoloration
• Controlled abrasive action prevents undercutting or gouging on finished surfaces
• High conformability allows effective finishing on contoured and irregular surface profiles
• Aluminum oxide abrasive delivers consistent cutting power across the wheel face
• Unitized construction provides uniform wear and maintains consistent finish quality over wheel life

Compatibility

Designed for use on standard bench grinders and finishing machines with a 1-inch arbor bore, suitable for metal finishing applications on stainless steel, brass, aluminum, and similar metals.

Installation Notes

Installation should be performed by a qualified operator familiar with bench grinder and abrasive wheel safety. Ensure the machine is powered off and unplugged before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the maximum RPM rating marked on the wheel or packaging. Operate in accordance with ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.
