Dynabrade DynaCut 150 grit sanding sheet is a triangular, no-hole, PSA-backed aluminum oxide abrasive designed for broad material coverage. The P grade aluminum oxide grain cuts sharply, so it removes material efficiently on hard and soft woods, plastics, fiberglass, composites and fabricated metals. The triangular shape supports detail work and corner access, giving better reach in tight or angled areas than rectangular sheets. The no-hole design gives a continuous abrasive surface, which helps maintain consistent contact on edges and profiles. The 150 grit grade suits general intermediate sanding where you need to refine surfaces without jumping straight to finish grits. As part of Dynabrade's coated abrasives line, this sheet is matched to Dynafine Detail Sanders DY57900, aligning sheet geometry with tool motion for steady, controllable stock removal.
This Dynabrade triangular no hole PSA sanding sheet uses a pressure sensitive adhesive backing, so it adheres across the entire pad face on Dynafine Detail Sanders DY57900. Full-surface adhesion helps the Cwt paper backing stay flat against the pad, which supports even pressure and consistent scratch patterns on wood, metal, aluminum, composites, solid surface materials and primed or painted surfaces. The moderately flexible paper backing lets the sheet follow light contours while still transmitting tool motion cleanly, so you can move from flats to edges without changing abrasives. The no-hole layout keeps the abrasive pattern uninterrupted at the tip and sides of the triangle, which helps when working into interior corners, narrow rails, or detailed fabricated metal parts.
The Dynabrade triangular PSA sanding sheet 93985 is designed for use on Dynafine Detail Sanders DY57900, so its size and shape track directly with that tool's triangular pad. On woodworking jobs, the 150 grit P grade aluminum oxide handles sanding of hard and soft woods, letting you level joints or prepare surfaces on frames, doors and trim. On fabricated metals and aluminum, the same grain cuts cleanly, so you can refine weld-adjacent areas or deburr edges without changing abrasives for each material. When working with plastics, fiberglass and composites, the non-loading coating resists clogging, so the sheet keeps cutting instead of glazing over as resins and dust build. Solid surface materials and primed or painted substrates also benefit from the non-contaminating, non-loading construction, maintaining predictable scratch patterns prior to further finishing steps.
The durable Cwt paper backing resists tearing under tool pressure, so the sheet holds together during extended passes along edges and tight corners, reducing interruptions from premature sheet failure. Because the backing remains moderately flexible, it bends enough to follow mild profiles, which helps avoid gouging when moving across transitions. The non-contaminating, non-loading coating keeps abrasive grains clear when sanding soft materials and coatings, which reduces streaking and uneven spots that would otherwise require re-sanding. The triangular no-hole design presents uninterrupted abrasive to the workpiece, so the tip and edges can reach into interior corners and narrow areas without dead spots. The PSA backing maintains uniform contact between the abrasive and the Dynafine detail sander pad, supporting an even scratch pattern across wood, metal, aluminum, composites, fiberglass and solid surface materials, which aligns surfaces for the next grit or finishing process.
The Dynabrade DynaCut 150 grit sheet sands hard and soft woods, plastics, fiberglass, composites, fabricated metals, aluminum, solid surface materials and primed or painted surfaces, so it supports mixed-material projects with one abrasive type.
The P grade aluminum oxide is sharp and free cutting, so it removes material efficiently across wood, metals and composites, helping reach target surface quality with fewer sanding passes.
The Cwt paper backing resists tearing and stays moderately flexible, so the sheet withstands tool pressure while conforming around edges and light contours for consistent contact.
The non-loading coating resists clogging on soft materials and coatings, so abrasive grains stay exposed longer and disc life extends during repetitive surface preparation.
The triangular no hole PSA design provides uninterrupted abrasive to the tip and edges, so the sheet reaches into corners and narrow profiles while staying firmly bonded to the pad.
The Dynabrade DynaCut triangular PSA sheet is used with Dynafine Detail Sanders DY57900, aligning the sheet geometry with the sander pad for controlled, detailed sanding.
The Dynabrade DynaCut 150 grit triangular no hole PSA aluminum oxide sanding sheet combines a sharp P grade grain, durable Cwt paper backing and non-loading coating to support steady stock removal on wood, metals, composites and coated surfaces. Its triangular format and PSA backing pair with Dynafine Detail Sanders DY57900, so detail pads stay fully covered right into corners and profiles. For shops and installers handling hard and soft woods, plastics, fiberglass, aluminum, solid surface materials and primed or painted work, this sheet offers one consistent abrasive setup across varied surfaces. Use it where controlled intermediate sanding and reliable disc life contribute directly to predictable finishing results.
