    摘要： A drilling tool with: a shaft; a seat at one end of the shaft; a drill bit, which is arranged on the seat; and a clamping section, which is provided on the shaft and can interact with the drill bit. Also provided is a tensioning screw, which is screwed into the shaft and comprises an expanding section as well as a contact section. The expanding section interacts with the clamping section, and the contact section interacts with the drill bit.

    摘要： A drill reamer (20) comprises an elongate body (21) disposed about a longitudinal axis. The elongate body comprises flutes (22a-22d) having separate hard cutting sections (27a, 28′a, 28″a, 28′b, 28″b) and a soft cutting section (24a, 24b). The soft cutting section is formed of a material such as carbide having a hardness that is less than that of the hard cutting sections, which may be formed of polycrystalline diamond. At least one first hard cutting section (27a) is axially displaced relative to at least one second hard cutting section (28′a, 28″a). The reamer has a tip cutting edge (23a, 23c) and tapered cutting edge portions (24a-24d) disposed at an acute angle relative to the longitudinal axis.
