3M 7100115789 Scotch-brite Laser Braze Unitized Wheel 9 in

Product Description

The 3M 7100115789 Scotch-Brite Laser Braze LB-UW is a unitized non-woven finishing wheel engineered to blend and smooth surface imperfections left by laser brazing in automotive production environments. Measuring 9 inches in diameter and 2.63 inches in width, the wheel pairs 3M Precision Shaped Grain with an open-web Scotch-Brite construction to deliver a faster cut rate and consistent surface finish on Silicon Bronze and similar metals. Fabricators and finishing technicians rely on it for high-throughput production work where both cut performance and finish quality must be maintained across extended run times.

This wheel is designed for laser braze finishing applications commonly found in automotive body production, where Silicon Bronze welds require blending before paint or coating processes. The flexible non-woven construction conforms to contours and weld profiles, making it well suited to both flat and mildly shaped panel sections. Its open-web structure resists clogging from metal debris, supporting sustained performance during production runs without frequent wheel changes. Minimum order quantity is 10 units per order.

Key Features

• 3M Precision Shaped Grain delivers fast cutting action and smooth surface finish on Silicon Bronze and similar metals
• Open-web non-woven construction resists loading and extends effective service life in high-throughput environments
• Flexible Scotch-Brite material conforms to weld profiles and contours, reducing the need for frequent recalibration or machine adjustments
• Unitized wheel construction maintains consistent performance throughout the life of the wheel
• 9-inch diameter suits standard bench and automated finishing equipment used in automotive production

Compatibility

Designed for blending and finishing Silicon Bronze laser braze welds on automotive body panels. Suitable for use with standard 9-inch-diameter arbor-mount finishing equipment. Verify arbor bore and machine RPM rating before mounting.

Installation Notes

Installation and wheel changes should be performed by qualified fabrication or finishing technicians following the equipment manufacturer's mounting instructions. Power down and lock out the machine before removing or mounting the wheel. Inspect the wheel for damage before each use and confirm that the machine's rated RPM does not exceed the wheel's maximum speed rating. Wear appropriate PPE including face shield and gloves during wheel changes and operation.
