    摘要： A drill bit has a shank, an intermediate shaft, and a cutting head and defines a longitudinal axis. The cutting head has a body having a front end, a rear end, and a peripheral sidewall, a primary cutting insert and a pair of auxiliary cutting inserts. The primary cutting insert is cross-shaped with a central portion with a cutting tip and four cutting arms each with a cutting edge extending radially outward from the central portion past the peripheral sidewall. The auxiliary cutting inserts are spaced radially outward from the central portion and circumferentially from the radial cutting arms, and have a cutting edge extending radially outward past the peripheral sidewall. A pair of primary dust egress slots and a pair of auxiliary dust egress slots are formed in the peripheral sidewall and configured to channel debris from the front end to the rear end of the body.

    摘要： A helical bit tool includes a bit head (1) with multiple helical pieces (2). Each helical piece has a side cutting edge (3) which faces on the direction of cutting operation. The surface of the side cutting edge which faces on the direction of cutting operation forms a cutting face (4). The back surface of the cutting face forms a rear cutting face (5). The step area (7) is formed on the top surface (6) of the bit head, in which forming a step or multiple steps with progressively lower heights from the center of the top surface to the outer flank. The periphery of every step is inclined with respect to the periphery of the bit head. A chamfering surface (9) is formed on where the rear cutting face interfaces with the step area and the top surface of the bit head. An upright cutting face (15) is formed on the side of the chamfering surface near the center of the top surface. The intersection of the chamfering surface, the step area and the top surface of the bit head forms a rear cutting edge (10). The intersection of the upright cutting face and the step area at its back side forms a chisel (11).

    摘要： A cutting blade 5 is formed by firmly fixing a tip 4 comprising a superabrasive compact to the top end of a shank 2. Nick grooves are formed on the cutting blade as a lateral separation means for separating swarf in the lateral direction and rounding treatment is applied to the cutting edge 6 of the cutting blade in order to configure a longitudinal separation means for separating the swarf in the longitudinal direction. The swarf is separated at the part of the cutting blade in both the lateral and longitudinal directions and fractionized into very fine pieces. By doing so, it is possible to provide a drilling tool which allows swarf to be surely separated in the lateral and longitudinal directions and fractionized even when a hole is created with a large machining thickness in the radial direction.

    摘要： Disclosed is a single-lip drill comprising a drill head (11) that is provided with a blade (12) which is embodied on said drill head. The blade encompasses a cutting edge (19) for machining a workpiece (16) in a cutting manner. At least one chip-forming device (21) which shapes chips (22) cut by the cutting edge is associated with the cutting edge. The chip-forming device is provided with a positive cutting angle (gamma) such that the mechanical and thermal stress can be reduced in the area of the blade (12). In addition, the chip-forming device can comprise a functional coating (29a, 29b) which is made especially of hard material and is applied after providing the drill with the exterior shape thereof.
