3M 7100132613 Scotch-brite Exl Pro Unitized Wheel 4 Inch

Product Description

The 3M 7100132613 Scotch-Brite EXL PRO EX-UW is a nonwoven aluminum oxide unitized abrasive wheel engineered for laser braze finishing on silicon bronze substrates. At 4 inches in diameter, this wheel uses an open web construction that resists loading and minimizes heat buildup, making it well-suited for work on heat-sensitive base materials. The layered, unitized build delivers consistent cut and finish throughout the life of the wheel and can run in both clockwise and counterclockwise directions. Installers and fabricators in metalworking and light manufacturing environments will find this wheel reduces secondary cleanup steps by resisting smearing and leaving cleaner edges after each pass.

This wheel is designed for blending and finishing silicon bronze components in laser brazing operations. It is well-matched to applications where surface cleanliness is critical before or after joining, and where thermal distortion of the base material must be controlled. The open web structure extends effective service life by shedding debris rather than loading, making it a practical choice for production environments where consistency across multiple workpieces is required.

Key Features

• Nonwoven aluminum oxide abrasive construction for controlled cut and finish
• Open web design resists loading and extends wheel service life
• Minimizes heat buildup to protect heat-sensitive materials during finishing
• Resists smearing for cleaner surfaces and reduced preparation time
• Bidirectional operation — runs clockwise or counterclockwise
• Tough, layered unitized construction maintains consistent performance throughout wheel life

Compatibility

Designed for use in laser braze finishing applications involving silicon bronze; suited for metalworking grinders and finishing tools that accept 4-inch unitized wheels with the appropriate arbor configuration.

Installation Notes

This wheel should be mounted by a qualified operator following the grinder or finishing tool manufacturer's arbor and speed rating specifications. Always verify the tool's maximum RPM rating meets or exceeds the wheel's rated speed before operation. Wear appropriate PPE including eye protection and gloves when mounting or operating abrasive wheels. Inspect the wheel for damage before each use and never operate a cracked or visibly damaged wheel.
