Abstract
A drilling tool includes a one-piece drill body having axially spaced front and rear ends. The front end includes pockets for receiving cutting inserts spaced by respective radial distances from a center axis of rotation of the drill body. Chip canals are formed in the front end, and a frustoconical chip space is formed in the drill body for connecting the chip canals to an axial passage which discharges chips through the rear end of the drill body.
