Dynabrade DynaCut 400 grit sanding sheet is a teardrop-shaped abrasive sheet designed for detail sanding on a broad range of surfaces and materials. The sheet uses premium P grade aluminum oxide, which cuts sharply and freely, helping remove material efficiently while leaving a fine 400 grit finish. This 400 grit grade suits final smoothing and nib removal where a consistent surface is important before finishing. The sheet is built on a durable C-weight paper backing that resists tearing, so it stays intact under pressure during sanding while remaining moderately flexible for contour work. A non-contaminating, non-loading coating resists clogging when sanding soft materials and coatings, which supports longer sheet life in repeat passes. The PSA backing allows the sheet to adhere securely to the tool pad, helping maintain control and consistent contact.
This DynaCut teardrop sanding sheet is made for use on Dynafine Detail Sanders DY58017, so its shape and PSA backing are tailored to that style of detail sanding pad. The no-hole design presents a continuous abrasive face, putting the full teardrop area to work on the surface. The durable C-weight paper backing resists tearing during use, which supports steady pressure without fragmenting the sheet. At the same time, the moderate flexibility of the backing helps the sheet follow small curves and profiles. The non-loading coating reduces clogging when working on softer materials or coated surfaces, which helps the abrasive remain effective over longer runs. Across wood, metal, aluminum, composites, solid surface materials, and primed or painted surfaces, the 400 grit abrasive helps refine surfaces toward a smooth, uniform finish.
This Dynabrade DynaCut teardrop no-hole PSA aluminum oxide sheet is suited for sanding hard and soft woods, plastics, fiberglass, composites, and fabricated metals, so it fits mixed-material shop work. On wood, the 400 grit P grade aluminum oxide provides fine sanding for surface smoothing before finishing. On metal and aluminum, the same abrasive supports light refinement and clean-up of surfaces without aggressive stock removal. When working solid surface materials, the fine 400 grit cut helps refine the surface toward an even appearance. The sheet is also identified as a good choice for primed or painted surfaces, where its non-loading coating and fine grit level support smoothing between coats. On fiberglass and composites, the sharp, free-cutting abrasive helps level high spots while the coating resists clogging from resin-rich areas.
The premium P grade aluminum oxide abrasive on this DynaCut sheet delivers a sharp, free-cutting action, which helps maintain a predictable scratch pattern as you sand across different materials. The durable C-weight paper backing resists tearing while still being moderately flexible, so the sheet holds together under load yet conforms enough to follow profiles and edges. That balance supports repeatable results whether you are sanding flat panels or contoured parts. The non-contaminating, non-loading coating works to resist clogging, particularly on soft materials and coatings, allowing the abrasive grains to stay exposed longer and continue cutting consistently. With a PSA backing, the sheet bonds to the Dynafine Detail Sander DY58017 pad, helping reduce shifting during use and supporting even contact. Across wood, metal, aluminum, composites, solid surface materials, and primed or painted surfaces, the 400 grit rating helps bring the surface to a uniform, fine finish ready for subsequent process steps.
This DynaCut 400 grit sanding sheet uses premium P grade aluminum oxide, which provides sharp, free-cutting action across hard and soft woods, plastics, fiberglass, composites, and fabricated metals.
The C-weight paper backing on this sheet resists tearing yet stays moderately flexible, supporting firm pressure on flat areas while still following gentle contours and edges.
This 400 grit sheet is described as a good choice for wood, metal, aluminum, composites, solid surface materials, and primed or painted surfaces in fine sanding steps.
The non-loading coating on this sheet resists clogging when sanding soft materials and coatings, which helps maintain consistent cutting action and extends sheet life.
This teardrop no-hole PSA sheet is used with Dynafine Detail Sanders DY58017, matching the pad profile for detail work.
The 400 grit rating on this DynaCut sheet supports fine surface smoothing and refinement, preparing wood, metal, and coated surfaces for subsequent finishing processes.
The Dynabrade DynaCut 400 grit teardrop no-hole PSA aluminum oxide sheet brings together a premium P grade abrasive, durable C-weight paper backing, and a non-loading coating for broad material coverage. Its 400 grit finish level supports fine sanding across wood, metal, aluminum, composites, solid surface materials, and primed or painted surfaces. Used on Dynafine Detail Sanders DY58017, the teardrop form helps reach edges and tighter areas while the PSA backing keeps the sheet stable. For shops handling varied materials, this construction offers a single sheet option for detail sanding and surface refinement.
