Dynabrade DynaCut 80 grit triangular sanding sheet uses premium P grade aluminum oxide, which cuts sharply so material removes efficiently on hard and soft woods, plastics, fiberglass, composites, and fabricated metals. The sheet is built on C-weight paper backing that resists tearing while remaining moderately flexible, so it holds up under pressure yet can still conform to mild contours and edges. The 80 grit abrasive profile levels surfaces and prepares them for further sanding or finishing where a medium cut is needed. The triangular shape works with Dynafine Detail Sanders DY57900 to reach into corners and tight areas during detailed work. A non-contaminating, non-loading coating helps resist clogging when sanding soft materials and coatings, so the abrasive stays open longer and remains productive over more strokes.
The sanding sheet uses a PSA backing, so it adheres directly to the Dynafine Detail Sanders DY57900 pad for a flat, secure connection during operation. The 6-hole pattern lines up with the matching Dynafine detail sander interface, allowing dust to move through the pad and off the work area while the tool runs. The triangular form fits the profile of Dynafine detail sander pads, so the abrasive wraps out to the points for reaching into corners and along tight inside edges. The combination of C-weight backing and PSA bond helps the sheet stay seated on the pad as pressure is applied across different materials during extended sanding passes.
This Dynabrade DynaCut abrasive sheet uses premium P grade aluminum oxide on C-weight paper, so the cutting action stays sharp across hard and soft woods, plastics, fiberglass, composites, and fabricated metals in the same workflow. The 80 grit rating provides a balance between stock removal and surface refinement, so it can knock down unevenness while still producing a surface ready for the next sanding or finishing step. The abrasive is identified as a good choice for wood, metal, aluminum, composites, solid surface materials, and primed or painted surfaces, so one grit can support cabinet components, solid surface fabrication, or metal detail work without constant media changes. The triangular form works with Dynafine Detail Sanders DY57900, so operators can bring the abrasive point into corners, over trim junctions, and along inside profiles that a round sheet would not reach as effectively.
The durable C-weight paper backing resists tearing while remaining moderately flexible, so it supports firm, even pressure on flat door panels or tops while still bending enough to feather edges without cracking. This balance helps maintain an even scratch pattern because the sheet stays intact and fully bonded as the pad moves across different profiles. A non-contaminating, non-loading coating is engineered to resist clogging when sanding soft materials and coatings, so dust and swarf do not pack into the abrasive as quickly. That resistance to loading keeps more cutting points exposed for longer, so each sheet maintains a consistent cut rate over more linear feet of sanding. By using PSA attachment with this backing and coating system, the sheet stays aligned on the Dynafine detail sander, supporting repeatable, smooth passes across wood, composite, or coated surfaces.
The Dynabrade DynaCut 80 grit triangular sheet is designed for hard and soft woods, plastics, fiberglass, composites, fabricated metals, aluminum, solid surface materials, and primed or painted surfaces, so one sheet can cover diverse shop work.
The non-loading coating on this sheet resists clogging when sanding soft materials and coatings, so abrasive grains stay exposed longer and support a steadier cut rate over extended use.
The C-weight paper backing resists tearing while remaining moderately flexible, so it handles firm pressure on flat areas yet still conforms enough for light edge and profile work without failing quickly.
This triangular 6-hole PSA aluminum oxide sheet is used with Dynafine Detail Sanders DY57900, so it aligns with the pad shape and hole pattern for detailed sanding tasks.
The 80 grit rating provides a medium cut that levels surfaces and removes material at a controlled rate, so it prepares wood, metal, or composite parts for subsequent finer grits or finishing.
The triangular shape extends abrasive out to three points, so the sheet reaches into corners, tight angles, and along inside edges more effectively than round or rectangular formats.
The Dynabrade DynaCut 80 grit triangular 6-hole PSA aluminum oxide on C-weight paper sanding sheet, part number 93639, delivers sharp P grade aluminum oxide on a durable, moderately flexible backing for varied shop materials. Its triangular form and hole layout match Dynafine Detail Sanders DY57900, so detailed corners and inside edges can be sanded using the same abrasive that handles broader surface prep across wood, composites, metals, and coated substrates.
