Dynabrade Dynafine replacement pad is a medium-density, self-skinning urethane foam pad designed to support a wide range of sanding applications using coarse to ultra fine grit abrasives. The 3-1/8 x 2-7/8 inch triangle shape works with detail-style sanders that accept this pad size, giving access into corners and tight areas where flat pads struggle. The 3/8 inch (10 mm) thick foam provides a balance of support and flexibility, so the abrasive can cut while still conforming to small contours. The non-vacuum design focuses all contact on the work surface without vacuum holes interrupting the pad face. Hook and loop backing on the face of the pad matches reattachable abrasive discs, keeping abrasive changes fast during production sanding jobs.
The pad mounts to the sander using four screws, creating a secure mechanical connection between tool and pad during extended use. This four-point attachment keeps the 3-1/8 x 2-7/8 inch triangle pad stable at the tip, which supports more controlled sanding along edges and into corners. The short nap hook face on the working side accepts reattachable hook and loop abrasives, so discs can be removed and reapplied without damaging the pad surface. That hook and loop interface helps when moving between coarse and ultra fine abrasives on the same job, because the pad stays on the sander while only the abrasive changes.
The 3-1/8 x 2-7/8 inch triangle shape of this Dynabrade pad positions the sanding points into inside corners and along narrow edges, which is valuable when working on casework, cabinet interiors, or tight trim details. Because the pad is non-vacuum, the full face of the self-skinning urethane foam supports the abrasive, so the abrasive can contact right out to the triangle tips. That uninterrupted face lets coarse grit discs cut into small areas without losing support at the edges. At 3/8 inch (10 mm) thick and medium density, the foam lets the abrasive follow slight irregularities in solid wood or composite materials, helping blend transitions instead of creating flat spots at the triangle corners.
The medium density urethane foam backing is engineered to work with coarse through ultra fine grit abrasives, so one pad handles both shaping and finishing passes in a sanding sequence. When paired with coarse grits, the foam support keeps the abrasive flat enough to remove material efficiently on faces and edges. With ultra fine grits, the same foam provides enough flex for smoothing and refining surfaces without harsh pressure points. The short nap hook face further supports this workflow because abrasives attach and release easily, encouraging frequent grit changes while the pad remains bolted by four screws to the sander. This combination of secure mounting, hook and loop abrasive attachment, and medium density foam helps maintain consistent results across multiple grit steps.
The Dynabrade Dynafine replacement pad is 3-1/8 x 2-7/8 inches, which positions the triangle shape for detail sanding and access into corners on tools using this pad size.
The pad is 3/8 inch (10 mm) thick, giving enough support to keep abrasives stable while still allowing some flex, which helps maintain control on edges and minor contours.
The pad is designed for coarse to ultra fine grit abrasives with hook and loop backing, so one pad can support both aggressive sanding and finishing steps.
The non vacuum design has no suction holes through the pad face, so the full surface supports the abrasive, which helps maximize contact on small parts and corners.
The Dynabrade 57955 pad mounts with four screws, creating a firm attachment between sander and pad that supports controlled sanding in tight or detailed areas.
The self skinning urethane foam forms a consistent, durable support layer under the hook face, which helps maintain even backing and sanding quality over time.
The Dynabrade Dynafine replacement pad pairs a 3-1/8 x 2-7/8 inch triangle shape with medium density, self-skinning urethane foam to support coarse through ultra fine sanding steps on detail sanders. The non-vacuum, short nap hook face keeps abrasives firmly attached while allowing fast changes. With four-screw mounting, the pad stays secure on the sander for repeatable work on corners, edges, and small panels. Choose this Dynabrade 57955 pad when a stable hook and loop triangle pad is needed for detail-focused sanding tasks.
