Description

The 3M 7000139649 Cubitron II 984F ceramic belt is a specialist abrasive made for precision polishing and finishing of titanium and other high-value alloys. Sized at 1.0" wide by 60.0" overall length (25.4 mm x 1524.0 mm), this compact belt fits backstands, benchtop grinders, and robotic applications with ease. Made with Precision Shaped Ceramic grains, the 3M 984F delivers a consistent cut and a long service life compared to conventional 36 grit sanding disc solutions. A YF-weight polyester cloth backing provides dimensional stability and resistance to tearing during repetitive polishing and finishing operations. Closed-coat construction concentrates abrasive coverage for reliable material removal while maintaining predictable surface quality in polishing tasks. The Film-Lok splice yields a low-profile, dependable joint suitable for high-speed backstand and centerless grinder applications in production environments. This belt is formulated for wet or dry use, enabling versatile implementation on roll grinders, flat finishers, and rapid grinders without compromising performance. Maroon in color and single-flex in form, the 3M Cubitron 984F II ceramic belt performs like a premium 36 grit grinding disc with improved life and finish consistency. Ideal applications include final blend, satin finishes, edge dressing and precision deburring where titanium substrate sensitivity demands controlled heat and cut. Specify 3M 7000139649 when you require a narrow, high-performance 3M cubitron 36 grit belt for demanding polishing and finishing workflows.
