Dynabrade Dynorbital replacement pad is an 8 inch, 48 hole vacuum disc pad designed as a medium density urethane sanding pad for hook and loop discs. The hook and loop attachment on this Dynabrade 56322 pad provides a quick-change disc interface, which speeds up abrasive swaps during production work or on-site sanding. The 8 inch (203 mm) diameter gives a broad sanding footprint, so each pass covers more surface on doors, panels, or wide stock. The 3/8 inch (10 mm) thickness urethane body provides a stable but cushioned backing, helping the disc stay in contact with the surface while still conforming to minor irregularities. The built-in 48 hole pattern is engineered to work with vacuum systems, pulling dust through the pad to the extractor, which helps maintain a cleaner sanding zone and supports consistent abrasive cutting.
This 8 inch vacuum disc pad uses a screw-mount attachment to fasten to the tool, giving a solid mechanical link between the Dynabrade Dynorbital replacement pad and the sander. That screw-mounted connection holds the medium density urethane body firmly, which helps the pad track smoothly under load. The hook-face surface accepts hook and loop sanding discs, so discs attach directly to the pad without separate adhesive steps. The dedicated 48 hole pattern in the pad aligns with a vacuum system design, routing air and dust through the disc and pad toward extraction, which supports a clearer view of the surface and steadier cutting as the disc stays less loaded with debris.
This 8 inch (203 mm) Dynabrade Dynorbital replacement pad is a vacuum disc pad built for hook-face sanding, so it suits sanding setups that rely on vacuum extraction and hook and loop abrasives. The medium density urethane construction gives it enough firmness to work well on flat stock, such as cabinet parts, furniture components, and millwork panels, while still having enough give to deal with light edge breaks or mild profiles. The 3/8 inch (10 mm) thickness helps the pad maintain a consistent contact patch on the work surface, supporting even scratch patterns during wider passes. The 48 hole layout is engineered as part of a vacuum system, so when paired with a matching vacuum setup the pad channels dust away through the pad face, which supports cleaner sanding and helps maintain visibility on the work.
The hook-face surface on this 48 hole hook and loop pad grips compatible hook and loop sanding discs across the full 8 inch area, which keeps discs seated flat during operation and helps prevent slippage as you move across the workpiece. That same hook and loop interface allows quick grit changes, so shifting from coarse leveling to finer finishing can happen with minimal downtime. The medium density urethane core balances rigidity and flexibility, so the pad supports the abrasive during more aggressive passes yet still cushions enough to avoid digging in on normal cabinet or furniture stock. With its 3/8 inch (10 mm) thickness, the pad provides a stable platform that transmits tool pressure evenly, which helps deliver repeatable surface quality across multiple parts in a run. The integrated 48 hole vacuum pattern works with vacuum systems to direct dust through the pad, which supports consistent cutting action by limiting disc loading.
The Dynabrade Dynorbital replacement pad has an 8 inch (203 mm) diameter, which provides a wide sanding area for panels, doors, and other larger workpieces.
The 48 hole design is built for vacuum systems, drawing dust through the pad, which keeps the sanding surface clearer and supports more consistent cutting across each pass.
This pad has a hook-face surface for hook and loop sanding discs, giving a quick-change disc interface that supports rapid grit changes between sanding steps.
The pad is 3/8 inch (10 mm) thick and made from urethane, providing a cushioned but stable backing that supports even material removal during sanding.
The Dynabrade 56322 pad is specified as medium density, giving a balance of firmness and flexibility that suits general sanding and intermediate finishing work.
This 8 inch vacuum disc pad is described as screw-mount, providing a secure mechanical connection to the tool for stable operation during sanding.
This Dynabrade Dynorbital replacement pad combines an 8 inch diameter, medium density urethane body, and a 3/8 inch (10 mm) thickness to support controlled sanding over larger surfaces. The hook and loop attachment on the hook-face surface speeds up disc changes, while the 48 hole vacuum design works with vacuum systems to pull dust through the pad. For shops and installers using a screw-mount 8 inch vacuum disc pad with hook and loop discs, this Dynabrade 56322 pad delivers a configuration tailored to vacuum sanding workflows.
