3M 7100133733 Scotch-brite Exl Pro Unitized Wheel 8 Inch

Product Description

The 3M 7100133733 is a Scotch-Brite EXL PRO EX-UW unitized nonwoven abrasive wheel built for laser braze finishing on silicon bronze. The open web, layered construction resists loading and heat buildup, delivering a clean, consistent finish without smearing. At 8 inches in diameter, this wheel handles blending and finishing tasks where surface quality matters and rework time must be kept low. It is installed and operated by metalworking and fabrication professionals working with heat-sensitive base materials.

This unitized wheel is engineered for laser brazing applications where silicon bronze is the primary workpiece material. The design resists smearing, which reduces surface prep time between passes. Its open web construction extends effective service life by preventing material loading during use. The wheel can run in either clockwise or counterclockwise rotation, giving operators flexibility in setup without requiring a dedicated spindle direction.

Key Features

• Nonwoven abrasive construction designed for blending and finishing silicon bronze laser braze joints
• Open web structure resists loading and extends wheel service life
• Tough, layered unitized build operates in both clockwise and counterclockwise directions
• Resists smearing for cleaner surfaces and reduced preparation between passes
• Minimizes heat buildup to protect heat-sensitive base materials
• Aluminum oxide (AO) abrasive mineral for consistent cutting action

Compatibility

Designed as an OEM-style replacement or direct-use unitized abrasive wheel for metalworking applications involving silicon bronze laser braze finishing on compatible angle grinders and bench-mounted arbors accepting 8-inch diameter unitized wheels.

Installation Notes

Installation and mounting should be performed by qualified metalworking or fabrication personnel. Power down and de-energize the grinder or arbor completely before mounting or removing the wheel. Verify the machine spindle speed rating meets or exceeds the wheel's rated maximum RPM before operation. Inspect the wheel for damage prior to each use and follow applicable ANSI B11 and OSHA abrasive wheel safety guidelines.
