3M 7100117441 Scotch-brite Laser Braze Unitized Wheel 3 in

Product Description

The 3M 7100117441 Scotch-Brite Laser Braze LB-UW is a unitized non-woven finishing wheel engineered to blend and finish imperfections produced by laser brazing in automotive manufacturing environments. The wheel combines Scotch-Brite open-web non-woven material with 3M Precision Shaped Grain abrasive for a faster cut rate and extended service life compared to conventional finishing media. At 3 inches in diameter, it is sized for use on angle grinders and die grinders commonly deployed in production finishing lines. Installation and wheel changes are handled by skilled maintenance technicians and production finishing operators.

This wheel is purpose-built for silicon bronze laser-braze seams on automotive body panels and structural components, where consistent surface blending is critical before downstream painting or coating operations. The open-web construction resists loading from soft non-ferrous metals, maintaining cutting effectiveness through longer runs without the frequent dressing or replacement required by conventional abrasive wheels. The flexible non-woven structure accommodates minor surface contours, reducing the need for recalibration between passes.

Key Features

• Engineered specifically for blending and finishing silicon bronze laser-braze seams
• 3M Precision Shaped Grain abrasive delivers faster cut rate and a consistent smooth finish
• Open-web non-woven construction resists loading on soft metals and extends service life
• Flexible Scotch-Brite material conforms to surface contours and reduces recalibration frequency
• Unitized construction maintains consistent performance as the wheel wears

Compatibility

Designed for use on silicon bronze and other non-ferrous metals in automotive laser-brazing finishing applications; confirm arbor size and RPM rating against grinder specifications before installation.

Installation Notes

Installation is typically performed by production maintenance technicians or tooling specialists. Ensure the grinder is fully de-energized and power is isolated before mounting or removing the wheel. Verify that the tool's maximum rated RPM meets or exceeds the wheel's rated speed before operation. Follow applicable ANSI B7 safety standards for abrasive wheel mounting and use appropriate eye and face protection during operation.
