3M 340D 80 Grit 3 x 24 Sanding Belt is a general purpose portable sanding belt that handles everyday abrasive work on a wide range of shop tasks. The belt uses aluminum oxide abrasive, which cuts aggressively while leaving a work-ready scratch pattern that prepares surfaces for further sanding steps or finishing. An X-weight cloth backing supports the abrasive grain, so the belt tracks well on portable sanders during continuous passes along edges, faces, or broad panels. The 3 in x 24 in size fits many common portable belt sanders, letting crews standardize on one belt size across multiple tools. The 80 grit grade provides a balance between stock removal and surface refinement, so it suits both shaping operations and intermediate sanding passes on many materials.
The 3M 340D aluminum oxide belt is built on an X-weight cloth backing, so it is suited to portable belt sanders that demand a durable yet flexible belt during repeated passes. The 3 in x 24 in dimension matches a common portable sander size, allowing the belt to seat correctly on standard 3 x 24 machines for predictable tracking. The 80 grit grading places this belt in the medium-coarse range, so operators can select it when they need a single belt to both remove stock and leave a surface ready for finer grit belts within the same abrasive system.
The 3M 340D and 341D line is described as a general purpose portable sanding belt, so this 3 in x 24 340D version suits routine sanding tasks across a workday. The belt uses aluminum oxide abrasive on an X-weight cloth backing, so it can support stock removal and surface leveling passes while remaining flexible enough for varied orientations on handheld sanders. The belt is noted as an excellent all-around abrasive belt for everyday use, so it fits well into standardized shop workflows where the same abrasive style must perform from rough shaping into intermediate surfacing. The 80 grit rating positions this belt for operations that need visible material removal without leaving an overly deep scratch pattern between steps.
This 340D belt is specified as an open coat belt that provides a good cut with less loading, so spacing between abrasive grains allows dust and swarf to clear more easily during sanding. That pattern helps the belt maintain a more even cutting action across its working life, which supports uniform surface appearance from one pass to the next. The X-weight cloth backing works together with the open coat aluminum oxide grain to keep the belt stable on the sander while still conforming enough for controlled pressure along the work surface. The 3 in x 24 in sizing means tension and tracking systems on compatible portable sanders can run the belt smoothly, helping operators hold a consistent line and reduce surface irregularities caused by belt wander.
