    摘要: A rock drill in which the depth of the recessed groove for accommodating the cutting body is made greater than the axial brazing-in depth of the cutting body whereby a largely stress-free seating of the cutting body results. In particular, for rock drills for making break-throughs, this recessed groove extended in the radial direction into lobes of a drill head can be used for locating cutting bodies in the lobes.

    摘要: A rock drill haivng a drill head with cruciform cutting tips is proposed which has improved chiselling properties in the case of percussive loading in hard rock or the like. For this purpose, the main cutting tip (4) is of a design know per se with secondary cutting tips (7,8) which are arranged transverse thereto and have a roof-shaped cross-section in side elevation. Additional, radially further outward bit points (16) for working the material result from the roof-shaped cross-section of the secondary cutting timps (7,8,) (cf. drawing).

    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 boring tool for producing undercuts in preformed holes. The boring tool has a cutting element which is provided at one end of a driving shaft. In order to produce the undercut, the driving shaft can be deflected at right angles to the axis thereof via a deflection mechanism. The deflection mechanism is accommodated in the boring tool, and is provided with a longitudinally displaceable deflection rod for positively deflecting the driving shaft. In the deflected position, the driving shaft is driven by a rotary drive which is separate from the turning drive. As a result, the undercuts can be very precisely produced.

    摘要: A drilling bit having two helical withdrawal grooves which extend from the drilling head in the direction toward the insertion or chucking end. The withdrawal grooves have least slope in the vicinity of the drilling head. In the other regions, the withdrawal grooves have a different slope. As a result, no cross-sectional jumps disposed at uniform intervals are provided on the drilling bit, so that transverse oscillations cannot be reinforced by partially constantly or continuously reflected pulses. A considerable reduction in noise is achieved. Furthermore, the central portion of the drilling bit, which is critical during drilling, receives great rigidity.

    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.
