3M 7100115972 Scotch-brite Laser Braze Unitized Wheel 9 Inch

Product Description

The 3M 7100115972 Scotch-Brite Laser Braze LB-UW is a unitized non-woven finishing wheel engineered to blend and smooth imperfections left by laser brazing in automotive production environments. At 9 inches in diameter and 2.63 inches in width, the wheel combines open-web Scotch-Brite non-woven material with 3M Precision Shaped Grain abrasive technology. This construction delivers faster cutting action alongside a consistent, smooth surface finish on Silicon Bronze and similar metals. Fabricators and automotive production technicians install this wheel on compatible right-angle or bench-mounted finishing equipment.

This wheel is purpose-built for laser braze blending on automotive body panels and structural components where Silicon Bronze is the primary joining material. Its unitized construction holds abrasive grain throughout the full thickness of the wheel, providing extended usable life in high-volume production settings. The flexible non-woven material conforms slightly to contoured surfaces, reducing the frequency of machine recalibration between runs. Suitable for both inline production and rework station applications.

Key Features

• Open-web construction resists loading and clogging, extending effective service life
• 3M Precision Shaped Grain provides aggressive cut rate with a smooth finish on Silicon Bronze
• Flexible non-woven Scotch-Brite material reduces need for machine recalibration and adjustments
• Unitized wheel body maintains consistent performance as the wheel wears down
• 9-inch diameter suits standard bench and right-angle finishing equipment used in automotive fabrication

Compatibility

Designed for use on Silicon Bronze and similar metals in laser brazing applications during automotive production. Verify arbor size and RPM rating compatibility with your specific finishing equipment before installation.

Installation Notes

Installation should be performed by qualified fabrication or production maintenance personnel. Power down and lock out the finishing machine before mounting or removing the wheel. Confirm the spindle speed of the host machine does not exceed the maximum RPM rating marked on the wheel. Inspect the wheel for damage before each use and replace immediately if cracking, delamination, or uneven wear is observed.
