3M 7100133777 Scotch-brite Exl Pro Unitized Abrasive Wheel 8 Inch

Product Description

The 3M 7100133777 Scotch-Brite EXL PRO EX-UW Unitized Wheel is a nonwoven abrasive wheel engineered for laser braze finishing on silicon bronze. The layered, unitized construction delivers consistent cut and finish across the wheel's full life, operating in clockwise or counterclockwise rotation. Open web construction resists loading and minimizes heat buildup, making it a reliable choice for heat-sensitive base materials. At 8 inches in diameter, the wheel handles blending and finishing operations where smearing or thermal distortion must be controlled. Fabricators and metal finishing professionals install this wheel on stationary or portable grinding equipment as part of a laser braze prep or cleanup workflow.

This wheel is suited for finishing and blending silicon bronze components used in laser brazing applications. The open web structure resists clogging during continuous use, extending effective service life and reducing downtime for wheel changes. It performs in both production and job-shop environments where surface cleanliness and edge definition after brazing are critical to downstream assembly or inspection steps.

Key Features

• Nonwoven, unitized construction blends and finishes silicon bronze laser braze joints
• Open web resists loading, extending service life and reducing wheel changes
• Operates clockwise or counterclockwise for flexible machine mounting
• Resists smearing, leaving cleaner surfaces with less additional preparation required
• Minimizes heat buildup to protect heat-sensitive base materials during finishing

Compatibility

Designed for laser braze finishing applications on silicon bronze; intended for use on stationary or portable abrasive wheel equipment rated for unitized nonwoven wheels at the appropriate spindle speed.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Verify the equipment spindle speed does not exceed the maximum rated speed marked on the wheel before mounting. Inspect the wheel for damage before each use and ensure the arbor, flanges, and guards are properly fitted. Never force a wheel onto a spindle or alter the wheel's center bore.
