摘要： The invention concerns a hard-metal cutting tip for use on a drill, particularly on a rock or concrete drill, including a drill point (3) extending through an axis of rotation of the drill, primary cutting edges (6) that slope downwardly on both sides, each composed of a primary land (4) and a primary flank (5), the primary flank (5) forming at the primary cutting edge (6) a primary lip clearance angle (14) with a plane perpendicular to the axis of rotation. To provide a hard-metal cutting tip that possesses high cutting, feed, bending and breaking strength and wear resistance, especially at its outer regions subjected to high peripheral speeds, the hard-metal cutting tip is realized such that the primary lip clearance angle (14) formed at the primary cutting edge (6) decreases with increasing distance from the drill point (3).

摘要： Drilling apparatus (50) for producing drilled holes with undercuts, with a drill (15), the drill shank (19) of which has a side cutting edge (14) protruding radially beyond the periphery (18) of the drill shank, and, on its circumference, opposite the side cutting edge (14), has a flattening, which makes possible the insertion of the side cutting edge (14) into the drilled hole, and the drill shank (19) of which is firmly connected with a connecting coupling (20), which is disposed in an articulated fashion between the drill (15) and a drill driving mechanism, permits wobbling motions of the shank as the drill (15) is rotating and has a drill shank-side coupling (29) with an axially movable indentor (85), which can be supported on an inclined plane (17) of a coupling (29) connected with the drill shank (19), which inclined plane (17) brings about the radial advance of the side cutting edge (14).In order to improve a drilling apparatus (90) with the aforementioned features in such a manner, that the drill (15), when producing a pre-drilled hole (12) in the workpiece (46), can be guided forcibly against radial motions by the axial advance of the drill (15) or pulled out of the finished, undercut, drilled hole, even when a self-alignment of the drill-shank side coupling (29) taking place as a result of centrifugal forces is not or not adequately possible, this apparatus is constructed so that the indentor (85) axially overlaps the drill shank-side coupling (29) in a position, which is not acted upon axially and is radially coupled positively with this coupling (29).

摘要： A device for securing a holder to a bore support formed with an undercut blind bore has a sleeve-like plug and a bolt received therein. The plug is formed with a central axis-defining passage having a smooth inner wall, a plurality of axially extending and radially throughgoing slits open at an inner end of the plug and defining a plurality of axially inwardly extending and radially deflectable tongues, and an annularly continuous outer portion from which the tongues extend. The bolt has a smooth outer surface and is shaped and dimensioned to fit complementarily into the passage with outward deflection of the tongues. The bolt and passage are of generally the same axial length so that when fully inserted in the passage the bolt is flush with the outer portion.

摘要： A bit assembly for undercutting a blind bore extending along a bore axis between an open outer end and a closed inner end and having a substantially cylindrical wall of a predetermned diameter centered on the bore axis and extending between the ends comprises a pusher body normally seated in the closed inner end of the bore and having an outwardly turned camming surface inclined to the bore axis, and a bit having a shaft extending along a longitudinal bit axis and having an inner end, an outer end, and a pair of longitudinally extending sides terminating at the inner end. One of the sides is at least partially cylindrical and centered on the bit axis and the inner end is formed with a camming surface engageable with the camming surface of the body and inclined to the bit axis. A blade fixed permanently and stationarily on the inner end projects radially from the one side of the shaft, the other side being cut back toward the bit axis.
