3M 7100133692 Scotch-brite Exl Pro Unitized Wheel 3 Inch Ao

Product Description

The 3M 7100133692 Scotch-Brite EXL PRO EX-UW is a nonwoven unitized abrasive wheel built for laser braze finishing applications on silicon bronze. The open web construction resists loading and heat buildup, delivering a consistently clean, smooth surface without smearing. At 3 inches in diameter, this wheel suits bench grinder and right-angle tool setups where precise, controlled finishing is required. The layered, unitized build allows operation in both clockwise and counterclockwise directions, giving technicians flexibility during use. It is installed and operated by metalworking professionals and fabricators working with heat-sensitive alloys.

This wheel is engineered specifically for blending and finishing silicon bronze components in laser brazing workflows. Its open web structure minimizes material loading, extending the effective service life of the wheel compared to conventional abrasive products. The heat-resistant design reduces thermal impact on sensitive base materials, making it appropriate for precision finishing tasks where surface integrity is critical. Typical applications include automotive body repair, HVAC copper alloy work, and industrial fabrication environments where laser braze joints require a clean, consistent finish before further processing or coating.

Key Features

• Nonwoven open web construction resists loading and extends service life
• Resists smearing for cleaner surfaces and reduced prep time
• Minimizes heat buildup to protect heat-sensitive base materials
• Layered unitized construction operates clockwise or counterclockwise
• Aluminum oxide abrasive suited for silicon bronze finishing
• 3-inch diameter fits standard bench grinder and right-angle tool arbors

Compatibility

Designed as an OEM-style replacement or direct-fit unitized wheel for bench grinders and right-angle finishing tools accepting a 3-inch diameter nonwoven abrasive wheel.

Installation Notes

Installation should be performed by qualified metalworking or fabrication personnel. Power down and lock out the tool before mounting or removing the wheel. Confirm that spindle speed does not exceed the maximum rated RPM marked on the wheel before operation. Wear appropriate eye and face protection during use, as nonwoven wheels can shed fibers at operating speed.
