Annular Cutters act as a type of drill bit used for drilling through metal. They merely cuts the outer edge of a hole. They drills precise, burr-free holes to tight tolerances without the use of pre-drilling or step drilling. These cutters are commonly used in magnetic drills, but they also perform well in mills and may even be converted for use in a drill press. Annular Cutters are tested under various parameters to ensure their high quality and effectiveness. These cutters are also suited for applications that need a completed, burr-free hole.
