Festool replacement pad gives you a dedicated soft backing surface for delta-style sanding, so the working face can match detailed woodworking and finishing tasks that benefit from a compliant pad rather than a rigid base.
The SAP description "REPL PAD, DELTA 100 X 150MM, SOFT" identifies this part as a soft delta pad in a 100 x 150mm size, which means the pad geometry is set up for triangular sanding where a pointed profile is used to reach into corners and tight sections on workpieces.
As a replacement pad in the Sanders and Accessories product class, this part is intended to take over from a worn pad on a compatible Festool sander, so the tool can continue to deliver consistent abrasive support without changing the sander body or switching to a different machine style.
The soft construction described in the product data lets the backing face conform more easily to small variations on wood surfaces, which helps the abrasive sheet stay in contact across the full delta shape during careful finishing or when working on contoured cabinet parts.
The soft delta 100 x 150mm pad configuration supports sanding workflows that depend on a pointed pad, so a Festool sander using this replacement pad can reach into inside corners and along edges where cabinetry parts meet, without changing to a different tool shape.
Because the pad is soft, the contact surface can adapt more easily to light curves and transitions on wood, which helps keep scratch patterns more even during progressive grits as the pad continues to back the abrasive across both flat and slightly contoured sections.
Positioning this part within Sanders and Accessories means the pad is treated as a service and setup component of a Festool sanding system, so shops can plan pad changeouts around wear or specific finishing stages while keeping the sander itself in regular rotation.
The delta 100 x 150mm shape directs the working area into a narrow point, which suits sanding tasks on woodworking projects where inside corners, rail-and-stile joints, or tight recesses need abrasive contact that a square or round pad cannot reach effectively.
When this soft Festool replacement pad is used on detailed cabinet or furniture parts, the dimensions allow the pad edges to track along profiles and narrow frames, so the same sander can handle both open faces and confined zones during surface preparation.
The Sanders and Accessories classification places the pad within a broader Festool sanding ecosystem, which means this specific part number can be selected whenever a soft delta configuration is needed for trim work, fine carpentry, or interior finishing on wood components.
By matching the 100 x 150mm footprint, the pad helps keep abrasive sheets aligned to the point and sides, which supports predictable edge reach when working along door panels, drawer fronts, or similar parts where precision at the tip of the pad matters.
The soft designation in "REPL PAD, DELTA 100 X 150MM, SOFT" signals that the backing layer is designed to compress slightly under load, so the abrasive can ride over minor surface variations without cutting too aggressively at high spots during finishing passes.
As a replacement pad identified by Festool manufacturer part number 577530, this component restores the intended backing characteristics of the original soft delta pad, which helps maintain familiar handling and sanding behavior after the previous pad has worn.
Using a pad from the Sanders and Accessories class keeps the interface between the sander and abrasive aligned to Festool specifications, so grip, pad geometry, and pressure distribution stay consistent across multiple pad changes in a professional woodworking environment.
Because the pad combines the delta 100 x 150mm layout with a soft backing, operators can rely on the pointed shape for access and the compliant support for fine-finish stages, which together reduce the need for hand sanding in corners once the workflow is dialed in.
The Festool replacement pad 577530 is a soft delta sanding pad in the Sanders and Accessories class, so it serves as a backing surface between a compatible Festool sander and the abrasive sheet.
The delta 100 x 150mm description defines the triangular pad size, so the pointed shape and edge length support sanding into corners and tight areas on woodworking projects.
The soft design gives the pad a more compliant backing surface, so the abrasive can follow slight surface variations and support smoother results during fine finishing work on wood parts.
A woodworker uses this Festool replacement pad when a soft delta backing is needed for detailed sanding, such as working in cabinet corners, frames, or other tight spaces.
The 577530 part number uniquely identifies this Festool soft delta pad, so it simplifies reordering and stocking the correct backing pad for compatible sanding tools.
This pad functions as a replaceable backing interface in the Festool Sanders and Accessories range, so it supports ongoing sander use while maintaining the intended delta pad geometry.
The Festool replacement pad defined as "REPL PAD, DELTA 100 X 150MM, SOFT" offers a soft delta backing footprint for sanding systems that rely on a pointed pad, so detailed woodworking and finishing tasks can keep using a consistent pad size and feel.
By using manufacturer part number 577530 within the Sanders and Accessories class, shops can align this soft pad with their Festool sanding setups, so worn backing pads can be swapped out while keeping the same delta 100 x 150mm working area in daily use.
