Dynabrade Dynamesh sanding disc is an 11-1/4 inch 320 grit hook and loop aluminum oxide mesh disc designed for use on vacuum compatible random orbital sanders. The mesh construction creates a unique dust-free solution, so sanding debris moves through the open mesh rather than building up on the surface, which supports better visibility and a tidier work area during fine sanding passes. The 320 grit P graded aluminum oxide abrasive is sharp, fast, and free cutting, so it cuts efficiently at this fine grit while still leaving a refined scratch pattern suited to finish preparation stages. A tough and durable phenolic resin bond system holds the abrasive grain firmly in place, which supports longer disc life and more consistent performance across multiple workpieces. This Dynabrade disc functions as a coated abrasive Dynamesh product, aligning with demanding shop environments where predictable cutting and reduced rework are important.
This Dynabrade Dynamesh 11-1/4 inch 320 grit disc uses a hook and loop attachment, so it fastens to compatible back-up pads without tools and can be repositioned as needed, supporting quick changes between grits or worn and fresh discs. The disc provides a dust-free solution for any vacuum compatible random orbital sander, so when used with a sander capable of vacuum extraction, dust moves through the mesh into the extraction path rather than collecting on the surface, supporting smoother gliding and less interruption to clear buildup. Because the design does not depend on back-up pad vacuum hole configuration, the same disc can connect across sanders with different hole patterns, which simplifies abrasive inventory and avoids matching discs to specific pad layouts.
This Dynabrade Dynamesh aluminum oxide mesh disc is suitable for primer sanding, so it supports leveling and refining primed surfaces before subsequent coating steps where a controlled scratch pattern is important. The disc also suits solid surface work, so it can be used to sand and blend these materials while the dust-reducing mesh design helps keep fine particulate moving into vacuum extraction. Composites are another stated application, so the sharp, free cutting aluminum oxide abrasive provides efficient material removal on these substrates without relying on closed-coated designs. The disc is also suitable for wood, so the same 320 grit mesh can move between wood sanding tasks and coated or composite surfaces, allowing a consistent abrasive choice across diverse jobs in the same workspace.
The open mesh construction reduces dust and reduces loading and clogging, so abrasive grains continue to cut cleanly instead of riding on packed debris, which helps maintain a uniform finish from the beginning to the end of the disc life. Premium P graded aluminum oxide abrasive is sharp, fast, and free cutting, so even at a fine 320 grit, the disc removes material efficiently while still producing a finish suitable for later finishing or coating stages. The tough and durable phenolic resin bond system holds abrasive grain firmly in place, so grains stay anchored under pressure, supporting longer disc life and stable performance on primer, solid surface, composites, and wood. These combined features align well with vacuum compatible random orbital sanders, since the mesh and bond allow dust to move out through the disc while the abrasive continues to cut, which helps reduce process interruptions and supports repeatable surface quality across multiple workpieces.
This product is a Dynabrade Dynamesh 11-1/4 inch 320 grit hook and loop aluminum oxide mesh sanding disc, so it functions as a coated abrasive disc for use with random orbital sanders.
The open mesh construction reduces dust from the sanding process and reduces loading and clogging, so dust moves away from the surface and cutting remains more consistent over time.
This Dynabrade Dynamesh disc provides a dust-free solution for any vacuum compatible random orbital sander regardless of back-up pad vacuum hole configuration, so it works across various pad layouts.
The disc is suitable for primer sanding, solid surface, composites, and wood, so it can be used across these materials in the same shop using one abrasive type.
The tough and durable phenolic resin bond system holds abrasive grain firmly in place, so the disc offers longer life and maintains cutting performance during extended sanding sessions.
Premium P graded aluminum oxide abrasive is sharp, fast, and free cutting, so it delivers efficient 320 grit sanding while supporting a fine, controlled finish on compatible materials.
The Dynabrade Dynamesh 11-1/4 inch 320 grit hook and loop aluminum oxide sanding disc combines open mesh construction, premium P graded abrasive, and a phenolic resin bond system, so it supports dust-reducing, free cutting performance on primer, solid surface, composites, and wood. Its compatibility with any vacuum capable random orbital sander regardless of back-up pad vacuum hole configuration allows one mesh disc style to serve across different tools in the shop. For sanding tasks needing fine 320 grit refinement with reduced clogging and extended disc life, this Dynabrade Dynamesh disc offers a focused solution for efficient, cleaner sanding operations.
