Dynabrade Dynamesh sanding disc is a 3 inch, 320 grit hook and loop aluminum oxide mesh sanding disc designed for use on vacuum compatible random orbital sanders. The open mesh construction reduces dust from the sanding process, so the work area stays cleaner during extended runs. This same open design reduces loading and clogging, which helps the abrasive keep cutting instead of skating over a dust film. The disc uses premium P graded aluminum oxide abrasive that is sharp, fast and free cutting, so it removes material efficiently on each pass. A tough, durable phenolic resin bond system holds the abrasive grain firmly in place, which supports longer disc life in continuous shop use. The disc is suitable for primer sanding, solid surface, composites and wood, so one disc type can serve multiple stations and materials in the same workflow.
This 3 inch, 320 grit hook and loop disc mounts on a random orbital sander using a hook and loop back-up pad, so changing discs is a quick peel-and-set motion during grit progressions. Because Dynamesh provides a dust-free solution for any vacuum compatible random orbital sander regardless of back-up pad vacuum hole configuration, the disc can be aligned by diameter rather than matching specific hole patterns. The open mesh construction lets air and dust move through the entire disc surface, so the dust extraction of the sander works across the pad rather than being limited to set hole locations. Using a 320 grit disc at this stage refines previous sanding scratches, helping prepare primer, solid surface, composite and wood surfaces for the next finishing or coating step.
This Dynabrade Dynamesh 3 inch disc is suitable for primer sanding, so it supports leveling primers and refining surfaces before subsequent coating stages on doors, panels and other painted parts. On solid surface materials, the premium P graded aluminum oxide abrasive provides sharp, fast and free cutting action, which helps blend seams and shape edges while maintaining control at 320 grit. When used on composites, the tough phenolic resin bond system holds abrasive grain firmly in place, so the cutting points remain stable as the disc moves over varying densities in the part. For wood applications, the 320 grit finish refines earlier sanding steps, helping smooth profiles and flat areas while the open mesh reduces dust that would otherwise load the disc during long passes. Because the same disc is suitable for primer sanding, solid surface, composites and wood, a single product type can move through different departments or work cells without changing abrasive format.
The 320 grit rating places this Dynabrade Dynamesh disc in a fine finishing range, which is useful for refining the surface after coarser grits have established flatness or shape. Using a hook and loop attachment on a random orbital sander allows fast disc swaps, so operators can move through grit sequences without slowing the line. The open mesh construction reduces dust from the sanding process and reduces loading and clogging, so the disc keeps its cutting action longer and supports a cleaner environment around the sander. With dust moving through the mesh rather than building on the face, the abrasive grain contacts the surface more consistently, which helps maintain an even scratch pattern that is easier to coat over. The tough, durable phenolic resin bond system that holds abrasive grain firmly in place supports longer life, so disc performance stays more consistent over the production run. Combined, these details give a sanding disc that supports efficient use on vacuum compatible random orbital sanders while working across multiple materials.
This Dynabrade Dynamesh disc uses premium P graded aluminum oxide abrasive, which provides sharp, fast and free cutting action to remove material efficiently during sanding operations.
The open mesh construction reduces dust from the sanding process, allowing dust to move through the disc and into the vacuum, which helps maintain a cleaner working environment and surface.
This Dynabrade Dynamesh disc provides a dust-free solution for any vacuum compatible random orbital sander, regardless of the back-up pad vacuum hole configuration used on the tool.
The hook and loop backing lets the disc attach to a hook and loop back-up pad, so disc changes are quick, supporting fast grit changes during multi-step sanding sequences.
This 320 grit disc is suitable for primer sanding, solid surface, composites and wood, so it can move between these materials in the shop while keeping the same abrasive format.
The tough, durable phenolic resin bond system holds abrasive grain firmly in place, which supports longer disc life and more consistent cutting over extended sanding runs.
This Dynabrade Dynamesh 3 inch, 320 grit hook and loop sanding disc combines an open mesh construction with premium P graded aluminum oxide abrasive, so it supports efficient, dust-reducing sanding on primer, solid surface, composites and wood. The tough phenolic resin bond holds abrasive grain firmly in place, which provides longer disc life and steadier cutting across multiple parts. For shops using vacuum compatible random orbital sanders regardless of back-up pad vacuum hole configuration, this disc offers a dust-free solution that supports clean, consistent surface preparation. Select this Dynabrade 91708 sanding disc when a fine finishing grit and dust-reducing mesh design are needed in the same abrasive.
