3M 7100133702 Scotch-brite Exl Pro Unitized Wheel 3 Inch

Product Description

The 3M 7100133702 is a Scotch-Brite EXL PRO EX-UW unitized nonwoven abrasive wheel engineered for laser braze finishing on silicon bronze. Built with an open web, layered construction, the wheel resists loading, smearing, and heat buildup to deliver a clean, consistent surface finish without additional prep work. At 3 inches in diameter, it is compact enough for detail finishing work while maintaining the structural integrity needed for continuous-duty use. The wheel can operate in both clockwise and counterclockwise directions, giving technicians flexibility in application setup. Packaging weight is approximately 1.582 pounds.

This wheel is intended for blending and finishing silicon bronze components in laser brazing operations. Its open web design prevents material from clogging the abrasive surface, extending service life and reducing downtime from wheel changes. The heat-resistant construction makes it well suited for use on heat-sensitive base materials where thermal distortion is a concern. Typical users include metal fabricators, welding shops, and industrial finishing technicians working with nonferrous alloys.

Key Features

• Open web construction resists loading and extends effective service life
• Layered unitized construction supports both clockwise and counterclockwise operation
• Resists smearing for cleaner surfaces and reduced preparation time
• Minimizes heat buildup to protect heat-sensitive base materials
• Designed specifically for blending and finishing silicon bronze laser braze joints

Compatibility

Designed for laser braze finishing applications on silicon bronze; suited for use with standard angle grinders and finishing tools that accept 3-inch unitized abrasive wheels.

Installation Notes

Unitized abrasive wheels of this type are typically mounted by metal fabrication technicians using compatible arbor-style angle grinders or finishing tools. Ensure the tool spindle speed rating meets or exceeds the wheel speed rating before use. Inspect the wheel for damage before each use and confirm the arbor nut is properly secured. Always wear appropriate PPE including eye protection and gloves when operating abrasive wheels.
