3M 7100133720 Scotch-brite Exl Pro Unitized Wheel 8 Inch

Product Description

The 3M 7100133720 Scotch-Brite EXL PRO EX-UW Unitized Abrasive Wheel is a nonwoven abrasive finishing wheel built for demanding surface conditioning tasks. Measuring 8 inches in diameter, this wheel is engineered specifically for laser braze finishing on silicon bronze. Its layered, unitized construction holds its shape through aggressive use and can operate in both clockwise and counterclockwise directions. The open web design resists loading, minimizes heat buildup, and reduces smearing — keeping finished surfaces clean and reducing the amount of secondary prep work required before or after the operation.

This wheel is used in industrial and fabrication environments where silicon bronze laser brazing is performed. It is well suited for blending and finishing brazed seams on automotive, metalworking, or precision manufacturing assemblies where surface cleanliness and minimal heat distortion are critical. Installers and operators working with heat-sensitive base materials will benefit from the wheel's low-heat operating characteristics. The unitized design maintains consistent cut and finish throughout the life of the wheel rather than degrading rapidly as layers wear.

Key Features

• Designed for laser braze finishing on silicon bronze substrates
• Open web construction resists loading and extends service life
• Unitized layered build operates clockwise or counterclockwise
• Resists smearing for cleaner surfaces and reduced preparation time
• Minimizes heat buildup to protect heat-sensitive materials
• Consistent finish performance throughout wheel life

Compatibility

Designed as an OEM-style unitized nonwoven abrasive wheel suited for angle grinders and bench-mounted arbors accepting 8-inch diameter unitized wheels used in laser braze finishing and surface conditioning applications.

Installation Notes

Mounting should be performed by qualified personnel following the tool and wheel manufacturer's safety guidelines. Confirm the host tool's maximum RPM rating meets or exceeds the wheel's rated speed before mounting. Power down and disconnect the grinder or arbor before changing wheels. Always use appropriate eye protection, hearing protection, and respiratory PPE when operating nonwoven abrasive wheels.
