3M 7000118391 Abrasive Belt 60 Grit Ceramic 777F

Product Description

The 3M 7000118391 is a coated abrasive belt designed for precision material removal on narrow stock, tubing, and tight-radius workpieces. Part of the 777F series, it features a ceramic aluminum oxide abrasive grain bonded to a heavy-duty polyester cloth backing with a closed-coat density. The 60-grit medium grade delivers aggressive stock removal while the YF-weight backing resists tearing under tension. At 0.25 inches wide and 18 inches long, this belt fits compact file belt tools and narrow-platen sanders used in metal fabrication, pipefitting, and maintenance grinding applications.

This belt is suited for use on metal surfaces including steel, stainless steel, and other hard materials. The closed-coat construction minimizes loading when working on ferrous metals and weld seams. It supports both wet and dry operation, making it compatible with coolant-fed grinding setups common in pipe and tube work. Fabricators, pipefitters, and maintenance technicians typically reach for this belt size for deburring, weld blending, and contour finishing where standard-width belts cannot reach.

Key Features

• Narrow 0.25-inch width fits file belt tools and tight-access grinding applications

Compatibility

Designed as a direct-fit replacement belt for compact file belt sanders and narrow-platen grinding tools accepting 0.25-inch by 18-inch abrasive belts.

Installation Notes

Abrasive belts of this type are installed and replaced by machinists, fabricators, and maintenance technicians using standard file belt or narrow-platen sanding tools. Disconnect or power down the tool before changing the belt. Confirm belt tracking and tension per the tool manufacturer's guidelines before resuming operation. Eye protection and appropriate PPE should be worn during use, particularly in wet grinding applications.
