Dynabrade DynaCut Extreme sanding disc is a 5 inch, 100 grit hook and loop aluminum oxide disc designed for aggressive stock removal with a consistent scratch pattern. The disc uses premium P graded aluminum oxide abrasives, which cut quickly and maintain a uniform surface, helping crew members move efficiently through sanding steps. Its extremely tough, tear resistant 3 mil film backing supports the grain during demanding use, so the disc resists edge damage when sanding edges or contours. The backing also generates fine finishes, which helps reduce follow-up sanding on many wood and coated surfaces. A proprietary clog free, pigment free coating creates a build-up resistant surface, so the abrasive stays open longer and continues to cut instead of glazing over. The hook and loop attachment system allows quick disc changes between grits and lets partially used discs be removed and reused later when they are not completely worn.
This hook and loop no hole sanding disc mounts to compatible hook and loop backup pads, so installers and finishers can press the disc onto the pad and begin sanding without alignment steps. The no hole design presents a continuous abrasive face, which keeps the working area fully covered during each pass. The 5 inch size fits tools built around that diameter, giving operators a familiar feel and control as they move across faces, frames, and smaller components. The 3 mil film backing holds flat while following light contours, supporting steady contact with the surface. Because discs can be removed when not completely worn and later returned to the pad, crews can keep specific discs dedicated to certain materials or stages while limiting waste.
This scalloped edge sanding disc is built on aluminum oxide abrasive, aligning it with common woodworking and finishing tasks where controlled material removal is needed. The scalloped edge geometry follows edges and profiles while distributing pressure more evenly along the perimeter, which supports a smoother transition when working near corners or detailed contours. The 5 inch diameter is suited to many handheld sanders found in shops, giving the disc a natural role on cabinet parts, trim components, and flat or slightly contoured surfaces. The proprietary clog free, pigment free coating keeps the abrasive surface more open as dust forms, so sanding on wood, coatings, or similar materials stays consistent rather than quickly loading the disc. This makes the disc appropriate for repeated passes over broad areas where a steady cut rate is valuable.
The premium P graded aluminum oxide formulation is selected for both fast cut and long life, so each disc can process more surface area before reaching the end of its useful life. Consistent grain sizing delivers a predictable 100 grit scratch pattern, which supports smooth transitions when moving to finer grits. The high performance 3 mil film backing is extremely tough and tear resistant, so the disc handles edge contact and directional changes without easily tearing, reducing interruptions to replace damaged discs. This same backing helps generate fine finishes, allowing operators to reach a uniform surface that is ready for the next sanding or finishing stage. The clog free coating further extends disc life by resisting build-up that can otherwise cause burning or uneven cutting. Because the hook and loop attachment lets discs be saved for future use when not completely worn, shops can rotate partially used discs onto appropriate jobs, gaining more value from each abrasive.

The hook and loop attachment system allows quick disc changes and lets partially used discs be removed and reused later, supporting efficient workflow and abrasive usage.
The proprietary clog free, pigment free coating creates a build-up resistant surface, so the abrasive stays open longer and maintains cutting performance over more passes.
The 100 grit rating supports balanced stock removal and surface refinement, making it suitable for intermediate sanding steps before moving to finer grits or finishing.
The no hole design provides a continuous abrasive face across the 5 inch disc, giving full contact with the surface and even coverage during each sanding pass.
The Dynabrade DynaCut Extreme 5 inch 100 grit hook and loop no hole sanding disc combines premium P graded aluminum oxide, a high performance 3 mil film backing, and a proprietary clog free coating to support fast, consistent sanding. The scalloped edge and continuous abrasive face suit detailed edges and broad surfaces while maintaining coverage. For shops that rely on hook and loop mounting and value longer disc life with predictable finish results, this aluminum oxide film disc is a practical choice for day-to-day abrasive work.
