3M 7100137203 Unitized Metal Finishing Wheel 8 Inch

Product Description

The 3M 7100137203 is a unitized metal finishing wheel designed for surface finishing work on stainless steel, brass, aluminum, and other metals. Built with a convolute construction wound around a fiber core, this wheel delivers consistent abrasive cutting action with controlled conformability. The open-web construction resists loading and runs cool, making it suitable for producing uniform brushed, satin, and mill finishes. At 8 inches in diameter, it fits standard bench or pedestal grinders used in metal fabrication and finishing operations. Licensed metalworkers and fabricators rely on this wheel type for professional surface prep and finish-matching tasks.

This wheel is suited for residential and commercial metal finishing applications including blending and matching 3 or 4 mill finishes on stainless steel. It is also used to create brushed or satin finishes on cutlery, appliance trim, builders hardware, and plumbing fixtures. The highly conformable design allows effective finishing on irregular or contoured surfaces, making it a practical choice for detailed or shaped workpieces that standard flat abrasives cannot reach consistently.

Key Features

• Convolute construction wound around a fiber core for smooth, fine, uniform finishing
• Open-web design resists loading and keeps operating temperatures low
• Controlled abrasive action helps prevent undercutting or gouging on finished surfaces
• High conformability allows consistent finishing on irregular and contoured surfaces
• Silicon carbide abrasive provides consistent cutting action across multiple metal types
• Unitized wheel construction delivers uniform wear throughout the life of the wheel

Compatibility

Designed as an OEM-style replacement unitized finishing wheel for bench grinders and pedestal grinders accepting an 8-inch diameter wheel.

Installation Notes

Installation and use should be performed by qualified personnel familiar with abrasive wheel safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the rated speed marked on the wheel or arbor. Always use appropriate eye protection and guards per applicable ANSI and OSHA abrasive wheel safety requirements.
