Reloaders looking to increase consistency and reduce variations from case to case know the importance of using a flash hole deburring tool. When brass is manufactured there are burrs that are sometimes created when the flash hole is tapped out. This tool quickly removes that burr creating more consistent ignition. This process only needs to be done once for the complete life of a piece of brass. This tool features a self-centering pilot collar with an adjustable stop and a comfortable plastic handle.
