    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 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 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: A rock drill including a helical shank and a drill head. The drill head has an end face pointing in a feed direction and at least one roof-shaped carbide cutting element on the end face of the rock drill. The carbide cutting element extends transversely across the drill head and has cutting edges. The end face of the carbide cutting element has an additional chip space at least in front of the carbide cutting element and includes an encircling step to create the additional chip space in the feed direction.
