    摘要: A rock drill which has a cutting tip of roof-shaped design at its front end is proposed. In order to achieve a reduction in the loading of the carbide cutting tip or an increased drilling capacity in particular in concrete, the flanks are subdivided into flank sections in order to achieve a slimmer embodiment of the drill head.

    摘要: A rock drill for hammer drilling machines is proposed, which has a helical shank and a drill head which is connected thereto and on whose end face are arranged a main cutting tip inclined in the shape of a roof and also auxiliary cutting tips disposed transversely thereto. The drill head has two laterally opposite flats for the formation of drilling dust grooves. In plan view the drill head has a very largely rectangular shape in cross section, an acute angle .beta..sub.1 being enclosed between the main cutting tip and the trailing auxiliary cutting tips.

    摘要: A drilling device with an arrangement for the detachable connection of a drill, especially a rock drill, percussion drill, hammer drill, and the like, to a receiving device, e.g. a drive head, which has a longitudinal bore for receiving the shank of the drill, and also has a driving part which is drivingly connectable to a drilling machine and is coaxial with the longitudinal bore. The drilling device furthermore comprises a drive transmitting member movable in the driving part transverse in the longitudinal bore of the receiving device. The drive transmitting or follower member is arranged to engage a bottom face of a recess in the shank of the drill. This recess has a segment-shaped cross section and has a bottom extending continuously over the entire corresponding width of the drill shank. On the driving part a securing part is mounted which is movable substantially in axial direction of the driving part into a position in which the drive transmitting member is arrested in its drive transmitting position and also into a position in which the drive transmitting member is released from its drive transmitting position and action.

    摘要: The invention relates to a drilling tool, especially for percussion drilling, which comprises a cutting element (3) that is configured as a plate (3) or head and that has at least one cutting edge (11) defined by a cutting face (6) and a free face (10). The cutting edge (11) is associated with a first free face section (10a) which is limited in a cutting plane at a right angle to the cutting edge (11) and parallel to the longitudinal axis (L) of the drilling tool (1) by a convex bulge (13) or a convex polygon outline. The vertical height of a rib (14) defined by the first free face section (10a) and an associated first cutting face section (6a) ranges from 0.1 mm to 1.0 mm.
