Dynabrade Dynamesh 8 inch sanding disc is a 120 grit hook and loop aluminum oxide mesh sanding disc designed for random orbital sanders. The hook and loop backing lets installers change discs quickly, helping maintain pace on multi-step sanding jobs without long changeover delays. The mesh, no-hole design works with any vacuum-compatible random orbital sander regardless of back-up pad hole pattern, so the same disc can move between different sanders in a shop without fit issues. The open mesh construction lets dust pass through the entire disc surface during sanding, which reduces dust buildup on the work and in the air. This dust management supports clearer sightlines while sanding and a cleaner work area around cabinetry, solid surface, or composite parts. The disc uses P graded aluminum oxide abrasive, which cuts sharply and freely, helping reach target scratch patterns efficiently on wood, primer, solid surface, and composite materials.
This 8 inch 120 grit hook and loop disc mounts to a compatible hook and loop backup pad on a random orbital sander, so installation is a simple press-on step that fits normal shop workflow. The no-hole mesh design means alignment is not driven by a specific hole pattern, which speeds disc placement because the installer only centers the disc on the pad. Once installed, the mesh allows vacuum systems on compatible sanders to pull dust through the disc surface, which supports consistent dust evacuation during passes over wood, primer, composites, or solid surface. The 120 grit grade positions the disc for intermediate sanding where a balance between stock removal and surface refinement is needed, helping build a controlled scratch sequence before finer grits or finishing steps.
This aluminum oxide mesh sanding disc is suitable for primer sanding, solid surface, composites, and wood, so it can stay in rotation across typical cabinet, fixture, or surface fabrication tasks. On primer, the sharp, free-cutting P graded aluminum oxide helps level and smooth coatings while controlling heat through the open mesh that lets dust escape. On solid surface and composites, the mesh backing and phenolic resin bond keep abrasive grain supported as the disc works across edges and flat runs. For wood applications, the 120 grit grade sets up an intermediate step that prepares panels, frames, and parts for finer sanding, while the reduced loading supports more consistent color and scratch appearance across the surface. Because the disc functions with any vacuum compatible random orbital sander regardless of pad hole layout, it fits into mixed-tool shops where installers move between different sanders during the day.
The open mesh construction reduces dust from the sanding process and reduces loading and clogging, so the abrasive surface stays more open and active, which supports a steady cut rate from the first pass through later stages of disc life. This dust movement also contributes to a cleaner environment around the workpiece, which is useful when sanding in finished spaces or near assembled cabinetry. The tough phenolic resin bond system holds the aluminum oxide grain firmly in place, so the disc maintains cutting ability under normal random orbital pressures on wood, solids, and composites. The 120 grit P graded aluminum oxide is sharp, fast, and free cutting, which lets installers remove material efficiently while leaving a consistent scratch pattern that transitions well to finer grits. Together, these characteristics support repeatable results from part to part and reduce interruptions to change discs during runs.
The Dynabrade Dynamesh disc is 8 inches in diameter and 120 grit, positioning it for intermediate sanding where material removal and surface refinement are both required.
The hook and loop backing lets the disc attach and detach quickly from a compatible backup pad, supporting fast grit changes during multi-step sanding sequences on the same tool.
The disc provides a dust-free solution for any vacuum compatible random orbital sander regardless of back-up pad vacuum hole configuration, so one disc style can serve varied pad layouts.
The disc is suitable for primer sanding, solid surface, composites, and wood, so it can be used across common cabinet, fixture, and surface fabrication applications.
The open mesh construction reduces dust from the sanding process and reduces loading and clogging, helping maintain a cleaner surface and more consistent cutting action.
The tough, durable phenolic resin bond system holds the abrasive grain firmly in place, supporting longer usable disc life under regular random orbital sanding loads.
This Dynabrade 91738 sanding disc combines 8 inch diameter, 120 grit P graded aluminum oxide, and an open mesh, no-hole design to support efficient dust-managed sanding on primer, solid surface, composites, and wood. The hook and loop backing works with compatible random orbital sanders and allows quick disc swaps, so grit changes can follow your sanding sequence without slowing the job. By using a disc that functions with any vacuum compatible random orbital sander regardless of back-up pad vacuum hole configuration, shops can streamline disc options across different tools. Select this disc when consistent cut, dust reduction, and extended disc life are priorities for your sanding workflow.
