Premium Chatter-Free Countersink

A premium version of our snail countersink also referred to as a "hole type deburring tool". The through hole resulting in a very clean free cutting action for chamfering or deburring. Chip clearance is excellent and suits soft alloys such as aluminium, brass and all ferrous materials. To resharpen these cutters the external surface can be touched up with a small diameter high speed grindstone.
