SurfPrep 6 inch 180 grit sanding disc uses a modified open-coat aluminum oxide grain that sheds dust efficiently, which helps maintain cutting action during use on larger panels or multiple parts. The abrasive layer also receives a sacrificial stearate coating that slows down loading from fine dust and resins, so the disc keeps cutting instead of glazing over in the middle of a sanding run. A film backing under the abrasive holds the grain flat and stable, which helps produce consistent finish sanding from the center of the disc out to the edge. This disc is built as a 6 inch diameter abrasive disc, so it suits sanders set up for that common pad size used in many wood shops. The 180 grit rating targets finish sanding, where you need visible scratch removal without jumping too fine for subsequent coating steps.
This SurfPrep aluminum oxide sanding disc uses a film backing that stays dimensionally stable under pressure, which helps the 180 grit abrasive track flat across face frames, cabinet doors, and panels. The 6 hole layout in the disc matches 6 hole sander pads, which routes dust extraction through the disc surface during sanding for steadier cutting and a cleaner scratch field. With 180 grit abrasive on a 6 inch disc, operators can move from leveling to finish sanding on broad surfaces while keeping a single disc type on the sander. The modified open-coat grain structure works together with the sacrificial stearate layer, which limits clogging as the disc loads with fine dust and extends useful sanding time between disc changes.
This SurfPrep abrasive disc is a 6 inch film AO H/L disc with 180 grit and 6 hole pattern, which positions it for use on 6 inch hook-and-loop sanders in woodworking shops. The modified open-coat aluminum oxide grain suits sanding tasks where material removal needs to stay controlled, such as final preparation of cabinet parts, doors, and trim before finishing. The film backing supports a consistent finish when sanding wide panels, which is useful when multiple parts must match after staining or clear coating. With a 6 hole pattern built into the disc, dust moves through the pad into extraction, which helps keep the abrasive face clearer during extended sanding runs. The 180 grit rating is suitable for finish sanding passes that follow coarser grits in a step-down sequence on wood or similar substrates.
The SurfPrep 6 hole sanding disc combines modified open-coat grain and a sacrificial stearate coating, which lets dust and resin release from the abrasive surface instead of packing into the scratch channels. This limits loading during sanding, so operators see more stable cutting and scratch uniformity from part to part. The film backing acts as a robust base under the aluminum oxide grain, which helps the disc resist tearing when it overlaps edges or hits small profiles on workpieces. That tear resistance reduces disc waste during daily production sanding. With a 6 inch diameter, 180 grit face, and 6 hole layout, the disc works as a consistent choice for finish sanding on common random-orbit sanders set up for dust extraction. The combination of grit, backing, and coating supports a workflow where finish quality and repeatability matter across batches.
This SurfPrep sanding disc uses aluminum oxide grain, which provides an abrasive surface suited to controlled material removal and finish sanding on wood and similar shop materials.
The modified open-coat aluminum oxide grain sheds dust between particles, which reduces loading on the disc face and supports longer, more consistent cutting during sanding passes.
The sacrificial stearate coating sits over the abrasive and takes on resin and dust, which slows down clogging so the underlying aluminum oxide continues to cut effectively.
The film backing provides a stable, flat support for the abrasive, which helps maintain a consistent scratch pattern across panels and detailed parts during finish sanding.
The tear resistant construction helps the disc handle edge contact and contours, which reduces disc failures during normal sanding tasks in cabinet and woodworking production.
The 180 grit abrasive on this disc targets finish sanding stages, which works well when preparing surfaces after coarser grits and before coatings are applied.
The SurfPrep 6 inch 180 grit sanding disc with aluminum oxide grain, sacrificial stearate coating, and film backing is built for controlled finish sanding in woodworking environments. Its modified open-coat structure and 6 hole layout support efficient dust management, while the tear resistant design helps extend disc use under everyday shop conditions. For operations standardizing on 6 inch random-orbit sanders and needing stable 180 grit performance, this abrasive disc provides a consistent option for finish sanding passes.
