    1. Drilling device for producing drilled holes (14) with an undercut (13), consisting of a drill bit with a drill tip (2) having a lateral cutting-edge (4) projecting radially beyond the drill shank (1), and of a drill bit holder (6) provided with a clamping shaft for an impact drilling machine and having a bulbous, radially projecting collar (9) provided with longitudinally extending slot openings, which collar, to form a swivel bearing, acts against a depression (10) of a stop plate (12) fitted over the drill shank (1) and having a sleeve-like centering extension (15) engaging in the drilled hole, characterized in that the stop plate (12) has axially extending members (17) adjoining the depression (10), which members are angled inwards behind the collar (9) of the drill bit holder (6).

    专利说明:

    The invention relates to the field of processing building materials and can be used for drilling holes for cutting suture.
    The purpose of the invention is to improve technological capabilities.
    FIG. 1 shows a device whose abutment plate is held by means of jumpers, a general view; in fig. 2 shows a device whose stop plate is held by means of a locking part, a general VIEW} in FIG. 3 is a view A of FIG. 2
    The device consists of a drill body 1 and a drilling plate 2 installed therein, which has face cutting edges 3 and side cutting edges 4 radially protruding above the drill body. For removal of the drilling flour, the body 1 is provided with grooves 5. To connect the drill to the fixture 6 of its fixture, the drill bit has an external thread 7, which fits into the corresponding internal thread 8 of the fixture fixture 6. The length of the drill determines the depth of the hole, since the spherical collar 9 of the fixture 6 for fastening the drill serves as a stop. The bead 9 rests on the groove 10 of the anvil plate 11. The drill rotates during the cutting process, thereby forming a backstop cutting 12 of the drilled hole 13. For centering the anvil plate 11, it has a liner-like centering juice 14 entering the drilled hole 13. The butt end of the The plate 11 has a convex steepness 15. By bending the edges of the adjacent to the chute 10 of the anvil plate 11 of the jumpers 16 behind the radially protruding shoulder 9 of the fixture 6 for fastening the drill is axially. fixing the support plate 11. The bridges 16 are spaced apart from each other and form promezkutochnye space, which are located on the same straight with the grooves 17 in the collar 9 of the fixture 6 for fixing the drill bit. To limit the angle of rotation of the device for fixing the drill side. bent bridges 16 are relative to the lateral top0

    device for fastening the drill corresponding gap 18.
    In the case of the drilling device according to FIG. 2, an abutment plate 11 is provided adjacent to the chute 10 of a junction 19, which has an external thread. This juice 19 is screwed as cup-shaped.
    the sleeve closure part 20 in such a way that the base 21 of the closure part 20 behind the collar 9 of the fixture 6 of the drill bit forms a stop. The base 21 of the locking part 20 has an annular recess 22 in which several openings 23 are located. In the case of drilling the ceiling drillings, the drilling flour is collected in the annular recess 22 and exits through the opening 23. Between the openings of the sleeve of the closing part 20 and the outer surface of the fixture 6 drill provided ring hole
    24, which limits the angle of rotation of the device for fastening the drill.
    A damping part is mounted on the front side of the 1 T thrust plate.
    25, consisting of rubber or a soft synthetic material, which dampens the action of the anvil plate 11 into the upper surface of the material 26 to be processed.
    The device works in the following way.
    The drill body 1 is installed in the drill securing device 6, on which the anvil plate 1 1 is fixed with a damping part 25 attached to it. The device is ready for operation. A hole 13 is drilled in the material to be processed. 26 When the drill 26 passes the material over its entire working length, the bead 9 is rotated along the groove 10 and the backing cutting 12 Thus, the hole with a smooth cutting is ready for operation.
