3M 7100117421 Unitized Finishing Wheel 3 Inch Laser Braze

Product Description

The 3M 7100117421 is a unitized non-woven abrasive finishing wheel engineered to blend and finish imperfections produced by laser brazing in automotive manufacturing environments. Built with 3M Precision Shaped Grain bonded into a Scotch-Brite non-woven web construction, the wheel delivers faster cut rates and longer service life compared to conventional abrasive wheels. At 3 inches in diameter, it is sized for use on inline or right-angle finishing equipment. Automotive production technicians and metal finishing operators use this wheel to achieve consistent, smooth surface results on silicon bronze weld seams without frequent tool adjustments.

This wheel is used in automotive body panel laser brazing operations where silicon bronze filler is applied and must be blended flush with surrounding sheet metal. The open web construction resists loading from soft metal debris, making it well suited for high-volume production lines where throughput and finish consistency are critical. It is also applicable to general non-ferrous metal finishing tasks that require controlled material removal and a refined surface finish.

Key Features

• Precision Shaped Grain construction delivers faster cutting action and extended wheel life on silicon bronze and similar non-ferrous metals
• Open web Scotch-Brite non-woven material resists loading, reducing downtime from clogging
• Flexible non-woven construction minimizes the need for tool recalibration or adjustment during production runs
• Unitized design maintains consistent hardness and cut characteristics throughout the full wheel life
• 3-inch diameter suits inline and right-angle finishing tools used in automotive fabrication

Compatibility

Designed for laser brazing finishing applications on silicon bronze and other non-ferrous metals in automotive production environments. Intended for use with compatible rotary finishing tools that accept 3-inch unitized abrasive wheels.

Installation Notes

This wheel should be mounted by a qualified operator following the tool manufacturer's specified RPM limits for unitized abrasive wheels. Verify that the spindle speed of the finishing tool does not exceed the maximum rated speed of the wheel before operation. Eye protection and appropriate PPE are required when operating abrasive finishing equipment. Inspect the wheel for damage before each use and replace if any deformation or core damage is present.
