Dynabrade DynaCut Extreme 5 inch sanding disc is a 1,500 grit aluminum oxide abrasive on a film backing designed for very fine sanding where surface finish matters. The premium P graded aluminum oxide abrasive delivers fast cut at this fine grit, helping you refine surfaces efficiently while still controlling scratch depth. Because the abrasive is engineered for long life, it supports extended sanding runs before disc changeout. The 5 inch diameter with no holes pairs with compatible 5 inch vinyl face back-up pads that do not rely on vacuum holes, so the entire face of the disc is usable. This fine 1,500 grit step prepares workpieces for polishing or final finishing where consistent, smooth results are required.
The pressure sensitive adhesive on this 5 inch 1500 grit PSA sanding disc is formulated to bond firmly to vinyl face back-up pads, so the disc stays flat and secure during sanding. When the disc is worn, the adhesive allows it to remove cleanly, helping keep pad faces free of residue for the next disc. The 3 mil film backing works together with the PSA to keep the disc stable under pressure, supporting controlled sanding passes on flat or contoured surfaces. With no holes, the abrasive face remains uninterrupted, which helps provide consistent contact across the pad during fine finishing steps.
This Dynabrade aluminum oxide film disc uses premium P graded aluminum oxide abrasives, so it suits fine sanding stages where predictable cut and uniform scratch patterns are needed. At 1,500 grit, the disc is appropriate for very fine surface refinement after coarser steps, bridging the gap toward polishing or final finishing. The extremely tough, tear resistant high performance 3 mil film backing allows the disc to handle edge work and curved areas while keeping the abrasive layer stable, which supports controlled finishing on detailed components. Because the film backing is designed to generate the finest finishes, it helps when working on parts where surface appearance is critical at the end of the sanding sequence.
The 3 mil film backing provides up to 4X the life of paper discs, so the disc stays in service longer and maintains a predictable cut rate over more parts. This extended life supports repeatable results on batch work by reducing how often discs are changed mid-run. The proprietary clog free coating is pigment free and delivers a buildup resistant abrasive surface, which helps limit loading when sanding materials that tend to clog abrasives. With less buildup, the disc continues to cut more evenly across its face, supporting uniform finishes and reducing the chance of random scratches from embedded debris. The pressure sensitive adhesive backing that adheres firmly to vinyl face back-up pads keeps the disc from slipping, helping each pass track cleanly for consistent results from part to part.
