3M 7100117420 Scotch-brite Laser Braze Unitized Wheel 3 Inch

Product Description

The 3M 7100117420 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. At 3 inches in diameter, the wheel combines Scotch-Brite open-web non-woven material with 3M Precision Shaped Grain abrasive, delivering faster cutting action and a consistent smooth finish on Silicon Bronze and comparable metals. Weighing 1.78 pounds, it is built for sustained use in production environments where finish quality and cycle time both matter. Fabricators and automotive finishing technicians are the primary installers of this product.

This wheel is intended for laser braze finishing applications in automotive production lines and metal fabrication shops. It is suited for blending surface irregularities on Silicon Bronze joints and similar non-ferrous metals after the brazing operation. The open-web construction resists loading during extended use, reducing downtime for wheel changes or process recalibration. It is used in both inline and handheld angle grinder setups wherever a consistent surface finish on brazed seams is required.

Key Features

• Unitized non-woven construction engineered specifically for laser braze blending and finishing
• 3M Precision Shaped Grain abrasive delivers faster cut rate and repeatable surface finish
• Open-web design resists loading and extends effective service life in production use
• Flexible Scotch-Brite material conforms to contours and reduces need for process recalibration
• Suitable for Silicon Bronze and other metals common in automotive laser brazing

Compatibility

Designed as an OEM-style finishing wheel for use in laser braze blending operations on Silicon Bronze and comparable metal substrates in automotive and metal fabrication applications.

Installation Notes

Installation is typically performed by fabricators or production technicians operating angle grinders or automated finishing equipment. Always power down and de-energize the spindle before mounting or removing the wheel. Verify that the arbor size, maximum RPM rating of the equipment, and wheel specifications are compatible before operation. Follow applicable ANSI B11 machine safety standards and the equipment manufacturer guidelines for abrasive wheel mounting.
