Dynabrade Replacement Pad For PSA Sanding Jobs

Dynabrade replacement pad medium no hole is a medium density urethane foam sanding pad built for a wide range of sanding work. The 3/8 inch (10 mm) thick pad provides a balance of support and flexibility, so coarse through ultra fine grit abrasives can cut while still conforming to contours on backsplashes and similar profiles. The self-skinning urethane foam construction creates a durable working surface that supports repeatable sanding passes over time. A premium vinyl face holds pressure sensitive adhesive (PSA) abrasives securely during use, which helps keep discs flat on the 3/4 inch (19 mm) diameter Dynafine backsplash reverse radius pad. This non-vacuum pad keeps the face solid for uninterrupted contact on the workpiece. As a Dynabrade part, it is built as a direct fit sanding interface for Dynafine backsplash reverse radius operations.

Key Pad Details That Support Sanding Results

• The self-skinning urethane foam body provides optimum support and flexibility, so the pad can back coarse to ultra fine grit abrasives while following curves without digging in.
• The 3/8 inch (10 mm) thick, medium density construction gives a controlled cushion under the abrasive, helping maintain consistent contact pressure across the sanding area.
• The premium vinyl face material securely holds PSA abrasives, so discs stay in place under load and track straight during extended sanding passes.
• The 3/4 inch (19 mm) diameter Dynafine backsplash reverse radius disc pad size suits tight backsplash-style areas, allowing controlled work along narrow profiles.
• The non-vacuum design keeps the pad face continuous, which supports full abrasive contact on the work surface during each stroke.
• The pad mounts with four screws, providing a solid mechanical connection that keeps the pad stable under tool vibration.

Mounting And PSA Abrasive Interface Details

This Dynabrade 58021 medium density pad mounts to the tool with four screws, which creates a rigid attachment point for sanding loads on the 3/4 inch diameter head. The 3/8 inch thick urethane foam layer then acts as the working cushion between the tool and the abrasive. A premium vinyl face is bonded to the foam and is designed specifically to hold pressure sensitive adhesive (PSA) abrasive discs. That vinyl face lets the PSA backing adhere firmly over the full 3/4 inch reverse radius surface, so the disc follows the backsplash radius and stays aligned as the pad moves. The non-vacuum configuration means the pad face is unbroken, which keeps the abrasive fully supported across its working area.

Using This Dynafine Reverse Radius Sanding Pad

Where This Dynabrade Urethane Pad Is Applied

This Dynabrade replacement sanding pad is described as a Dynafine backsplash reverse radius disc pad, so it is intended for backsplash-style sanding work where a reverse radius head fits into a concave or profiled area. The 3/4 inch (19 mm) diameter focuses the abrasive into a small footprint, which helps when working along narrow backsplashes or similar tight shapes. The 3/8 inch (10 mm) thick, medium density urethane foam supports the disc so it can follow those profiles while still backing the abrasive grains. Because the pad is non-vacuum, the full face contacts the surface, which suits situations where constant abrasive contact along the radius is important. The Dynabrade branding and Dynafine description position this pad within a sanding system aimed at detailed profile finishing.

How Pad Design Supports Repeatable Sanding Quality

The self-skinning urethane foam provides a uniform working surface, which helps each disc sit evenly and work consistently from one sanding job to the next. Medium density construction balances firmness with give, so the pad does not collapse too much under pressure yet can still flex enough to follow a reverse radius shape. The premium vinyl face material is engineered to hold PSA abrasives securely, reducing disc shift that could mar a backsplash profile. Because the pad mounts with four screws, the interface between tool and pad stays rigid, allowing the urethane layer and vinyl face to control how the abrasive meets the work. The non-vacuum layout keeps abrasive coverage continuous across the disc, supporting predictable scratch patterns on coarse through ultra fine grits.
