3M 7100189112 Flexible Diamond Belt 40x4 Inch

Product Description

The 3M 7100189112 is a flexible diamond abrasive belt designed for blending and finishing operations on hard-to-grind materials. The 6454J series belt measures 40 inches in length and 4 inches in width and uses a diamond mineral abrasive bonded with a metal bond system over a highly flexible backing. This combination delivers consistent cut on thermally sprayed coatings, ceramics, carbides, composites, chilled iron, and non-ferrous metals. Technicians and machinists working with difficult substrates rely on this belt where conventional abrasives fail to maintain performance through extended runs.

This belt is suited for lighter-duty blending and finishing tasks, particularly where contour conformance matters. The flexible backing allows the abrasive to follow curved or irregular profiles, making it appropriate for finishing contoured workpieces in precision grinding, thermal spray finishing, and composite surface preparation environments. Typical applications include industrial maintenance shops, aerospace component finishing, and carbide tooling surface work.

Key Features

• Diamond mineral abrasive delivers aggressive cut on ceramics, carbides, composites, and other hard-to-grind materials
• Highly flexible backing conforms readily to curved and irregular contours
• Metal bond system adds durability and extends usable belt life
• Open dot construction minimizes loading and prolongs abrasive service life
• Sized at 40 inches long by 4 inches wide for standard belt grinding setups

Compatibility

Designed for use on belt grinders and finishing machines accepting 40-inch by 4-inch abrasive belts; suited for applications involving thermal sprays, ceramics, carbides, composites, chilled iron, and non-ferrous metals.

Installation Notes

Installation is typically performed by a machinist or industrial maintenance technician. Power down and lock out the belt grinder completely before changing abrasive belts. Verify belt tension and tracking per the machine manufacturer's guidelines before resuming operation. Inspect the belt for cracks or separation at the splice before each use and do not exceed the maximum operating speed rating of the machine.
