Dynabrade DynaCut Extreme sanding disc is a 6 inch, no hole, 120 grit aluminum oxide on film abrasive disc designed for sanding applications where consistent finish and cut rate are important. The premium P graded aluminum oxide abrasive is manufactured to give a fast cut, which helps reduce sanding time on each part. That same P graded construction also supports a long service life, so discs stay productive over more work before being changed. The abrasive is bonded to a 3 mil high performance film backing, which is extremely tough and tear resistant in use. That film backing generates fine finishes while standing up to edge contact and repeated passes. A proprietary clog free coating on the abrasive surface is pigment free, creating a buildup resistant face that maintains cutting ability over longer cycles, especially in dustier sanding conditions.
This 6 inch no hole PSA abrasive disc uses a pressure sensitive adhesive backing that bonds directly to vinyl face back-up pads. That adhesive creates a firm attachment across the full disc diameter, giving solid support under the abrasive grain for consistent contact with the workpiece. When a disc reaches the end of its useful life, the adhesive backing is designed to release cleanly from the vinyl face. That clean removal helps keep pad faces free of leftover adhesive, supporting smooth application of the next disc and maintaining even support across the sanding surface for repeatable finish quality.
This Dynabrade aluminum oxide on film sanding disc is a 6 inch no hole design, suited to sanding operations that do not rely on vacuum holes through the disc face. The 120 grit abrasive positions the disc for applications needing a balance of stock removal and surface refinement, such as intermediate sanding steps. Because the backing is a 3 mil high performance film that is extremely tough and tear resistant, it supports use on edges, corners, and profile transitions where paper-backed discs can be more vulnerable to tearing. The premium P graded aluminum oxide abrasive is manufactured for a fast cut, so on each part the disc can quickly bring surfaces down to the desired level before finer steps.
The proprietary clog free coating on this disc is pigment free and forms a buildup resistant abrasive surface, which is useful when sanding generates fine dust that can otherwise load the grain. By resisting clogging, the disc maintains its cutting action longer between changes, supporting extended runs on similar materials. The film backing also generates fine finishes, allowing the same disc to contribute to both stock leveling and surface preparation in a single grit step. With its pressure sensitive adhesive backing engineered to adhere firmly to vinyl face back-up pads, the disc works reliably in workflows that standardize around vinyl-faced random-orbit or rotary pad systems for consistent support.
The extremely tough and tear resistant 3 mil film backing structures the abrasive layer on a stable base, so the grain stays supported even under pressure, which promotes uniform scratch patterns across the sanding path. That durability means that when the disc encounters sharp edges or hardware cutouts, the backing resists tearing, allowing more of the abrasive surface to remain usable over the life of the disc. Because this film backing generates fine finishes, operators can use the 120 grit disc to leave surfaces that transition smoothly to subsequent finishing steps, helping maintain a consistent appearance on adjacent parts.
The proprietary clog free coating is engineered to create a buildup resistant surface, reducing the tendency of dust and debris to pack into the spaces between abrasive particles. As the coating sheds material away from the disc face, the exposed P graded aluminum oxide continues to cut efficiently, which supports steady removal rates even late in the disc life. Its pigment free formulation means there is no added colorant in the coating itself, which is important when working on lighter or visible surfaces where unwanted color transfer would be undesirable. Together with the pressure sensitive adhesive system that adheres firmly to vinyl face back-up pads yet removes cleanly when discs are worn out, these features support repeatable performance over multiple disc changes and extended production runs.
This sanding disc uses 120 grit premium P graded aluminum oxide, providing a fast cut while supporting long life for intermediate sanding steps.
The 3 mil high performance film backing is extremely tough and tear resistant, so it supports edge work and generates fine finishes in routine sanding.
This disc uses a pressure sensitive adhesive backing that adheres firmly to vinyl face back-up pads and releases cleanly when the disc is worn out.
The disc is no hole because the abrasive face has no vacuum holes, and it uses PSA backing so it bonds over the full face of a 6 inch pad.
The proprietary clog free coating creates a buildup resistant abrasive surface, so dust clears more readily and the disc keeps cutting over longer use.
The pigment free coating avoids adding color from the coating itself, supporting clean-looking results on lighter or finished surfaces.
The Dynabrade DynaCut Extreme 6 inch 120 grit PSA no hole aluminum oxide on film sanding disc brings together P graded aluminum oxide, a 3 mil high performance film backing, and a proprietary clog free, pigment free coating. That combination supports fast cut, fine finishes, and long life in sanding workflows that rely on vinyl face back-up pads with pressure sensitive adhesive discs. Selecting this disc aligns those features with day-to-day production demands, helping maintain steady finish quality and efficient material removal across repeated sanding tasks.
