3M 7100133703 Scotch-brite Exl Pro Unitized Wheel 3 Inch

Product Description

The 3M 7100133703 Scotch-Brite EXL PRO EX-UW is a nonwoven aluminum oxide unitized abrasive wheel engineered for laser braze finishing on silicon bronze. At 3 inches in diameter, this unitized wheel features an open web construction that resists loading, minimizes heat buildup, and delivers a clean, smooth surface without smearing. The layered construction allows operation in both clockwise and counterclockwise directions, making it a practical choice for metal fabrication and finishing professionals working with heat-sensitive base materials.

This wheel is intended for laser brazing applications where surface cleanliness and edge definition are critical. It is well suited for finishing silicon bronze parts prior to or following laser braze operations in precision metal fabrication environments. The open web design extends effective service life by reducing clogging, which lowers the frequency of wheel changes during production runs. Technicians in automotive, industrial, and specialty fabrication shops will find this wheel applicable wherever silicon bronze components require controlled surface finishing.

Key Features

• Aluminum oxide nonwoven abrasive construction resists loading and extends service life
• Open web design minimizes heat buildup to protect heat-sensitive materials
• Resists smearing for cleaner surfaces and reduced preparation time
• Unitized, layered construction operates clockwise or counterclockwise
• Delivers clean edge definition suited to laser braze finishing on silicon bronze

Compatibility

Designed for laser braze finishing applications on silicon bronze components in precision metal fabrication settings.

Installation Notes

Install this wheel on a compatible rotary tool or bench grinder rated for the wheel diameter and speed before beginning surface work. Ensure the spindle and arbor are properly matched to the wheel bore before mounting. Power down and de-energize all equipment before changing wheels. Follow applicable ANSI B7 wheel-mounting guidelines and always use the appropriate eye and face protection when operating abrasive wheels.
