The 3M 7100242858 is a heavy-duty 984F Cubitron II ceramic belt made for fast material removal and dependable service in industrial workshops. Equipped with precision-shaped ceramic grains, the 3M 984F maintains aggressive cutting performance longer than conventional abrasives. The 36+ grit formulation delivers high stock-removal rates where a 36 grit sanding disc is typically used, ideal for shaping and weld blending. A YF-weight polyester cloth backing stabilizes the belt under high pressure, improving life and tracking during continuous use. Closed-coat construction increases abrasive coverage, giving consistent cut rates and extended belt life in heavy grinding tasks. The Film-Lok splice offers a low-profile, robust joint designed for reliable runnability in automated and manual finishing systems. Single-flex capability lets this 3M cubitron 984F II ceramic belt conform to varied tool geometries for deburring, polishing and surface prep. At 132.0" overall length and 3.406" width, the 3M 984F is sized for long production runs and conveyorized finishing lines. Use the 3M cubitron 36 grit belt to shorten cycle times, reduce belt changes and lower abrasive consumption in production workflows. Choose 3M 7100242858 for dependable heavy-duty grinding where a 36 grit grinding disc alternative is required.
