Benchmark Abrasives 3" quick change mandrel provides the backing support needed to run matching 3" Type R quick change discs on compatible tools. The rubber holder supports the abrasive during sanding, grinding, blending, and finishing while the larger 3" diameter gives you more working coverage on broader surfaces.
The reusable holder allows fast disc changes without replacing the backing assembly, making it a practical accessory for shops that regularly switch between abrasive types or grit levels. Its 1/4" shank mounts into compatible collets or chucks, giving you a simple way to run a wide range of 3" Type R quick change abrasives on properly matched tools.
