    摘要: A drill includes support pads for supporting and guiding the drill in the drill hole. The support pads are formed as parallelepiped-shaped cemented carbide bodies which each have two wing-shaped protrusions on their longitudinal sides. In a corresponding way, the drill head of the drill includes recesses with two bulged parts on the long sides. This gives the support pad a determined axial position and strengthens the support pad at the weakening caused by the central hole. Further, the support pad can be turned half a revolution if one of its ends becomes damaged since the end spaces do not have to function as abutment surfaces.

    摘要: A drilling tool for drilling in metals has in its front part cutting insert-carrying cartridges, for instance 3, 5 or 7 in number. The peripheral cartridge (6) carries a peripheral cutting insert (7). This peripheral cartridge is fastened in the drill by a locking screw (16) that extends in a slot (17) in the drillhead. Radially inside of the peripheral cartridge is a wedge (15) which can be displaced axially and thereby regulate the radial position of the peripheral cartridge and cutting insert and, thereby, the cutting diameter. When the desired radial adjustment has been attained, the peripheral cutting insert is fixed by the locking screw (16). In this way, a very exact adjustment of the cutting diameter is obtained.

    摘要: 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.

    摘要: A drilling tool includes a drill body having axially spaced front and rear ends. The front end includes tangential pockets for carrying cutting inserts spaced by respective radial distances from a center axis of rotation of the drill body. Two chip canals are formed in the front end surface adjacent respective pockets for conducting away chips. The canals are interconnected by a chip space located rearwardly of the front surface, to form in the drill body a bridge which extends diametrically and carries a plurality of the pockets. Each insert pocket includes an axially extending abutment surface against which a rear wall of a respective insert engages. Each of the abutment surfaces and rear walls is of semi-circular shape.
