Dynabrade DynaCut Extreme sanding disc is a 5 inch, 220 grit abrasive disc designed for fast cut and long life, so fine sanding passes remove material efficiently while maintaining control on detail work. The disc uses a premium P graded aluminum oxide abrasive, which delivers a consistent scratch pattern that supports predictable finishing from part to part. Its aluminum oxide on film construction pairs the cutting mineral with a 3 mil film backing, so the disc stays extremely tough and tear resistant under edge pressure and around contours. A scalloped edge around the disc spreads contact over small segments, helping the disc track smoothly over edges and profiles while limiting grab. The no hole face presents full abrasive coverage to the surface, which concentrates the 220 grit cut where it is needed during each pass.
This 5 inch sanding disc uses a hook and loop attachment system, which grips compatible backup pads firmly while allowing discs to be peeled away without damage to the pad. The hook and loop interface makes disc changes quick and easy, so switching between grits during a sanding sequence adds minimal downtime. When a disc is not completely worn, the hook and loop system allows it to be removed and saved for future use, supporting efficient use of each disc. The no hole configuration keeps the hook and loop pattern uninterrupted across the pad interface, which helps maintain even support across the full disc diameter during sanding.
This 5 inch aluminum oxide on film scalloped edge sanding disc is set up for fine work where control and finish quality matter. The 220 grit rating provides a fine cut suitable for refining surfaces after coarser grits, so transitions between sanding stages remain smooth. The scalloped edge shape distributes contact across multiple small arcs, which helps the disc follow mild contours and edges without digging in harshly. Its extremely tough and tear resistant high performance 3 mil film backing supports this edge work, holding the abrasive stable while the disc tracks along corners and profiles. Because the film backing is designed for durability, it maintains disc shape as the abrasive wears, which helps keep the sanding pattern consistent throughout the disc life.
The disc is manufactured with a premium P graded aluminum oxide abrasive, which is selected for fast cut and long life so each disc continues to remove material effectively over extended use. This abrasive is paired with a proprietary clog free coating that is pigment free and provides a build-up resistant abrasive surface, so dust and debris do not load the face as quickly, further extending usable life. The extremely tough and tear resistant high performance 3 mil film backing also contributes to longevity, standing up to aggressive passes and edge contact that would typically damage paper discs. Together, these features support up to four times the life of paper discs, which reduces disc turnover, limits sanding interruptions, and helps maintain consistent finishing results across larger jobs.
This disc uses premium P graded aluminum oxide abrasives, which provide a consistent scratch pattern and support fast cut with extended usable life in repeated sanding passes.
The extremely tough 3 mil film backing resists tearing, so the disc holds together on edges and corners and maintains an even sanding surface throughout its life.
The proprietary clog free coating is pigment free and build-up resistant, so the abrasive surface stays open longer and continues to cut rather than loading with dust.
The hook and loop attachment system makes disc changes quick and easy, so moving between grits or swapping partially used discs fits smoothly into the workflow.
The no hole design keeps full abrasive coverage across the disc face, so the entire 5 inch surface contributes to the 220 grit cut on every pass.
This sanding disc offers up to four times the life of paper discs, so fewer discs are used over time, reducing changeovers and supporting longer sanding runs.
The Dynabrade DynaCut Extreme 5 inch 220 grit hook and loop no hole scalloped edge sanding disc pairs premium P graded aluminum oxide with a tough 3 mil film backing to support fast, consistent fine sanding. Its proprietary clog free, pigment free coating and build-up resistant surface keep the abrasive cutting effectively, while the hook and loop attachment system streamlines disc changes and allows partially worn discs to be reused. For workloads that demand extended disc life and predictable finishing, this aluminum oxide on film disc is suited to maintaining productivity across repeated sanding cycles.
