Dynabrade DynaCut Extreme 6 inch sanding disc uses 180 grit aluminum oxide on film, so it delivers a fine, controlled cut that suits jobs needing a uniform surface ready for subsequent steps. The disc is built on high strength polyester film, which holds the abrasive mineral firmly and supports steady, predictable cutting across the full 6 inch face. A 25 hole vacuum pattern is designed into the disc, allowing dust to move away from the work area and helping the abrasive stay effective as sanding progresses. The hook and loop backing provides a mechanical grab onto compatible backup pads, so the disc can be positioned, removed, and repositioned without damaging the film. This abrasive disc fits into abrasive workflows where a 180 grit step is needed to refine surfaces while maintaining control over cut and finish quality.
The hook and loop backing on this Dynabrade disc mates with hook compatible 6 inch backup pads, so the installer can press the disc into place and have it held evenly across the face. The 6 inch size and 25 hole layout are arranged together, so when used on backing pads with a corresponding pattern, dust can be directed away through the aligned holes as the disc works. Because the abrasive is aluminum oxide on high strength polyester film, it maintains a uniform cutting behavior while mounted, which supports repeatable results between disc changes. The 180 grit rating defines where this disc fits into a sanding sequence, so it can be selected as the fine step that transitions from more aggressive grits toward finishing operations.
This Dynabrade DynaCut Extreme 6 inch 180 grit hook and loop disc is specified as part of the Dynabrade abrasive discs line, so it is suited to abrasive tasks where precise and consistent finishes are required. The web description notes that 3M 268L and 366L are fast cutting abrasives that provide a precise and consistent uniform finish and excellent use for solid surface finishing, which positions this style of aluminum oxide on film disc in applications where a controlled finish is critical. With aluminum oxide placed on a high strength polyester film backing, the disc supports steady mineral exposure as it moves over solid surface materials, helping maintain a predictable scratch pattern that can be followed by finer steps. The 6 inch diameter allows coverage of a meaningful area on countertops or panels, which can streamline leveling and refinement of seams or transitions. Because the disc is 180 grit, it works in the range where solid surface finishing often calls for a balance between cut rate and surface refinement, allowing material to be leveled while still targeting a uniform visual result.
The premium micron graded mineral is placed on high strength polyester film, so each abrasive particle is supported by a stable backing that resists stretching during operation. This construction helps the disc maintain its shape as it travels over the work, which supports a uniform contact patch between the abrasive and the surface. The presence of a 25 hole configuration means the disc is prepared to work with vacuum extraction systems that share a compatible pattern, channeling sanding residue off the surface through the holes. By moving dust away from the sanding interface, the abrasive mineral stays more exposed for cutting, which keeps the 180 grit action closer to its intended performance throughout its life. The hook and loop mounting further contributes, because the backing engages the pad across the full disc area, supporting even pressure application that aids in achieving repeatable finish results from job to job.
The Dynabrade DynaCut Extreme disc uses aluminum oxide on film, so it provides a consistent cutting action suited to controlled surface refinement.
The disc has a hook and loop backing, so it attaches to compatible pads and can be installed or removed quickly during sanding sequences.
The 25 hole pattern allows dust to pass through the disc toward extraction, so the abrasive surface stays clearer and cutting remains more consistent.
The high strength polyester film backing supports the abrasive mineral, so the disc holds its shape and helps maintain a uniform scratch pattern.
The 180 grit Dynabrade disc provides a fine cut, so it serves as a refining step between more aggressive grits and later finishing operations.
The web description notes excellent use for solid surface finishing, so this disc fits tasks where a precise, uniform finish on solid surfaces is needed.
The Dynabrade DynaCut Extreme 6 inch 180 grit hook and loop 25 hole aluminum oxide on film sanding disc provides a defined combination of size, grit, backing, and hole pattern that fits structured abrasive workflows. With premium micron graded mineral on high strength polyester film, the disc is built for precise, consistent finishes, particularly where solid surface finishing performance is important. For industrial and occupational environments where a 180 grit step is needed on compatible 6 inch hook and loop vacuum pads, this Dynabrade abrasive disc 91567 offers a clearly defined option that aligns with controlled cutting and uniform finish requirements.
