3M 7000118437 Abrasive Belt 80 Grit 3/4x20-1/2 in Ceramic

Product Description

The 3M 7000118437 is a coated abrasive belt designed for precision grinding and finishing on metal and other hard surfaces. Built on a YF-weight polyester cloth backing, this belt delivers the flexibility and durability needed for contour and flat stock removal work. The ceramic aluminum oxide abrasive grain runs at 80 grit, a medium grade well suited for aggressive material removal while still leaving a workable surface finish. Closed coat density ensures consistent cutting action across the full belt surface. At 0.03 pounds, this belt is lightweight and sized for compact or handheld belt sanders used in fabrication, maintenance, and toolroom applications.

This belt measures 3/4 inches wide by 20-1/2 inches long, fitting narrow-profile belt sanders and file belt tools commonly used in welding shops, metal fabrication facilities, and general maintenance environments. The 777F series ceramic construction handles both wet and dry operation, making it adaptable to coolant-assisted grinding setups as well as dry bench work. It is typically installed by machinists, fabricators, maintenance technicians, and skilled tradespeople who require reliable cut rate and consistent finish on ferrous and non-ferrous workpieces.

Installation Notes

Belt replacement should be performed with the sander fully powered down and unplugged. Verify the belt tracking adjustment after installation and before resuming operation to prevent edge wear or belt failure. Eye protection and appropriate respiratory PPE should be worn during abrasive belt work per standard shop safety practices. Inspect the platen and idler roller for wear or debris before mounting a new belt.
