Abstract
The present invention relates to a bit for processing the inside diameter of a work material, the bit having on the outer surface of a shank a vibration preventing structure comprising a vibration absorption body made of a silicone material, and a hollow wire rod, thereby absorbing the vibration generated from a machine tool, preventing resonance generated between the work material and a tool, and thus, enabling the implementation of a slickenside from ultra-precision machining.
