Faster and more accurate than twist drilling Annular Cutters drill a burr-free finished hole by cutting only the material around the periphery of the hole. This forms a solid slug which automatically pops out. Less time and energy are consumed per hole Faster feed rates are achieved with more cutting teeth and less tool wear Lighter, less powerful drilling equipment can be used Able to drill holes which are difficult or impossible to do accurately with conventional twist drill tooling - with no predrilling or stepdrilling required
