3M 7100133775 Scotch-brite Exl Pro Unitized Wheel 8 Inch

Product Description

The 3M 7100133775 Scotch-Brite EXL PRO EX-UW is a nonwoven unitized abrasive wheel engineered for laser braze finishing on silicon bronze. The open web construction resists loading and minimizes heat buildup, which is critical when working on heat-sensitive base materials. At 8 inches in diameter, this wheel delivers a clean, consistent edge without smearing, reducing the amount of prep and cleanup required between finishing passes. It is used in industrial fabrication environments where surface cleanliness and dimensional integrity after blending are non-negotiable.

This unitized wheel is built for precision finishing applications involving silicon bronze laser braze joints. The layered, unitized construction allows the wheel to run in either clockwise or counterclockwise rotation, giving operators flexibility depending on machine setup. The open web design resists clogging and extends service life compared to conventional bonded abrasive wheels. Typical users include metal fabricators and industrial finishing technicians working on automotive, aerospace, or precision welding operations that incorporate laser brazing processes.

Key Features

• Designed specifically for blending and finishing silicon bronze laser braze joints
• Open web construction resists loading and extends effective service life
• Runs clockwise or counterclockwise for flexible machine compatibility
• Resists smearing for cleaner surfaces and reduced prep time
• Minimizes heat buildup to protect heat-sensitive base materials
• Unitized construction maintains consistent cut and finish throughout wheel life

Compatibility

Designed for laser braze finishing applications on silicon bronze. Verify arbor size and RPM rating compatibility with your angle grinder or finishing machine before installation.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder and abrasive wheel safety standards. Always power down and disconnect the tool before mounting or removing the wheel. Confirm the machine RPM does not exceed the maximum rated speed marked on the wheel. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.
