Features
Annular Cutters cut only the periphery of the hole,ejecting the remaining center as a slug.It produces accurate burr-free holes to close tolerances without pre-drilling or step drilling.
Best used with a drill press or magnetic drilling machine, both for their stability against high torque forces created by such a drill bit and lower RPMs compared to other types of drills. these cutters can be easily used with light duty drilling machines or portable magnetic base drilling machines.
