  • Publication number: 20110033253
    Abstract: There is provided a drill bit capable of performing a continuous drilling operation on a high-strength workpiece such as a tempered tile and the like. The drill bit comprises a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body and coupled to the receptor portion of the bit body to form a channel in which a capillary phenomenon occurs, and having an opening formed in one end thereof; and a cutting portion provided in the opening of the drilling portion to drill a workpiece. The drill bit thus configured may be useful to enable a continuous drilling operation on the high-strength workpiece, to enable the refilling of a cutting oil used to cool the high-strength workpiece, to shorten a time for the drilling operation on the high-strength workpiece, and to drill the high-strength work-piece to the maximum extent using the minimum number of drill bits.
