3M 7100133690 Scotch-brite Exl Pro Unitized Wheel 3 Inch Ao

Product Description

The 3M 7100133690 is a Scotch-Brite EXL PRO EX-UW unitized nonwoven abrasive wheel built for laser braze finishing on silicon bronze. The open web construction resists loading and minimizes heat buildup, making it suitable for heat-sensitive base materials. At 3 inches in diameter, this wheel fits standard right-angle grinders and finishing tools used in fabrication and metalworking environments. HVAC, sheet metal, and precision fabrication technicians install this wheel when a clean, smear-free edge is required after laser brazing operations.

This wheel is intended for blending and finishing silicon bronze parts in laser brazing applications. The unitized layered construction allows operation in both clockwise and counterclockwise directions, giving installers flexibility in tool orientation. It is suited to production environments where consistent surface finish and reduced cleanup time are priorities. The open web structure extends effective service life by resisting material loading during extended use.

Key Features

• Nonwoven open web construction resists loading and extends service life
• Minimizes heat buildup to protect heat-sensitive base materials
• Resists smearing for cleaner surfaces and reduced prep time after finishing
• Unitized layered construction operates clockwise or counterclockwise
• Designed specifically for laser braze finishing on silicon bronze

Compatibility

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

Installation Notes

Installation is performed by fabrication or sheet metal technicians using standard grinder arbor hardware. Confirm the tool spindle speed rating meets or exceeds the wheel rating before mounting. Power down and disconnect the tool from its power source before changing wheels. Follow all applicable ANSI B11 and tool manufacturer safety guidelines for abrasive wheel mounting and operation.
