3M 7000045139 Abrasive Belt 36 Grit 1/2x18 in Ceramic 984F

Product Description

The 3M 7000045139 is a coated abrasive belt engineered for aggressive stock removal on metal, composites, and hard materials. Part of the 984F Series, it features a ceramic abrasive grain rated at 36 grit Very Coarse grade, making it well suited for grinding, weld blending, and heavy surface conditioning work. The belt measures 1/2 inch wide by 18 inches long and is built on a polyester cloth backing with YF backing weight for durability under high-pressure applications. Closed coat density ensures consistent, aggressive cut throughout the belt's service life. Machinists, fabricators, and industrial maintenance technicians are the primary installers and users of this belt.

This belt is designed for use on narrow-width belt grinders and file belt sanders commonly found in fabrication shops, maintenance facilities, and production environments. Its 1/2 inch by 18 inch format fits compact inline and handheld belt units used for detail grinding, deburring tight contours, and weld seam removal. The ceramic grain construction supports both wet and dry operation, allowing use with or without cutting fluid depending on the material and machine setup. It is appropriate for aggressive work on ferrous and non-ferrous metals where fast cutting action is required.
