Dynabrade DynaCut Extreme sanding disc is a 5 inch, 800 grit, pressure sensitive adhesive abrasive disc designed for fast cut and long life on sanding jobs that demand consistent results. The premium P graded aluminum oxide abrasive cuts aggressively while staying uniform, so each pass removes material predictably and helps maintain surface flatness. The extremely tough and tear resistant high performance 3 mil film backing supports the grain during use, helping the disc stay intact under edge loading and repeated passes. This film backing also generates the finest finishes, so installers can move from leveling to pre-finish prep on the same disc when the specification calls for an 800 grit scratch pattern. The proprietary clog free coating is pigment free, so it resists buildup without transferring unwanted color to the work surface during sanding.
This 5 inch PSA no hole sanding disc uses a pressure sensitive adhesive backing that bonds directly to vinyl face back-up pads, creating a secure interface during sanding. Because the adhesive adheres disc firmly, the disc stays flat against the pad, which supports even contact and helps avoid chatter marks. When the abrasive is worn out, the backing is designed to remove cleanly from the vinyl face, so the pad surface remains smooth for the next disc without leftover residue. The no hole design presents a continuous abrasive face, which gives a full sanding area across the 5 inch diameter when the application does not rely on through-pad dust extraction.
This Dynabrade DynaCut Extreme 800 grit disc uses premium P graded aluminum oxide abrasives, delivering a combination of fast cut and long life that fits repeated fine sanding passes. On jobs where controlled stock removal at a fine grit is required, the uniform grain helps avoid random deep scratches that would telegraph through subsequent finishing steps. The extremely tough and tear resistant high performance 3 mil film backing supports the abrasive layer across flat areas and contours, so the disc stays usable through extended work instead of breaking down early. Because the film backing generates the finest finishes, the disc is suited to applications where an 800 grit surface is the specified stopping point before coating or between-coat leveling. The no hole 5 inch format presents uninterrupted abrasive across the face, which supports consistent contact when used with compatible vinyl face back-up pads.
The proprietary clog free coating on this disc is pigment free and provides a buildup resistant abrasive surface, which helps keep the cutting grain exposed longer in situations where fine dust normally fills the abrasive. This behavior extends disc life in fine grit work, so sanding can proceed across larger areas without frequent disc changes. Because the coating is pigment free, it avoids adding its own color to the work surface, supporting clean sanding on materials where color transfer would be unacceptable. The pressure sensitive adhesive backing adheres disc firmly to vinyl face back-up pads, creating a stable bond that resists slipping during operation. When the disc is worn out, the adhesive removes cleanly from the pad, which keeps the backing pad ready for immediate reuse with a fresh disc and maintains a smooth interface for consistent results from disc to disc. Sold in packs of 50, this format supports stocking for repetitive shop or jobsite sanding routines.
The 800 grit abrasive provides very fine sanding, so surfaces reach a refined scratch pattern suitable for finish prep or between-coat leveling where that grit size is specified.
The high performance 3 mil film backing is extremely tough and tear resistant, so the disc stays intact under pressure and maintains a consistent sanding surface longer.
The premium P graded aluminum oxide abrasive cuts fast while remaining uniform, which supports predictable material removal and a repeatable scratch pattern across multiple parts.
The proprietary clog free coating creates a buildup resistant surface, so fine dust is less likely to load the disc and the abrasive stays cutting effectively over more passes.
The pressure sensitive adhesive backing bonds firmly to vinyl face back-up pads and then removes cleanly when the disc is worn, supporting quick, straightforward disc changes.
The 5 inch no hole design provides a continuous abrasive surface, so the entire disc face contacts the work when used with suitable pads that do not rely on through holes.
The Dynabrade DynaCut Extreme 5 inch 800 grit PSA no hole aluminum oxide on film sanding disc combines premium P graded aluminum oxide, a high performance 3 mil film backing, and a proprietary clog free coating to support repeatable fine sanding results. The pressure sensitive adhesive backing works with vinyl face back-up pads, holding the disc securely during sanding and releasing cleanly when worn out. With its focus on fast cut, long life, and the finest finishes at 800 grit, this disc fits demanding abrasive work where consistency and reduced changeover directly affect throughput.
