Because of this, that the jacket wall recesses only for cooling serve the drill head, these can also be parallel to Be aligned axis of rotation of the cylinder head drill. However, an embodiment is preferred in which the grooves formed are inclined to the drilling axis.
  • the grooves have a rectangular or circular cross section. Will continue suggested that the grooves be open on both sides are.
  • the cylinder head drill Made in one piece from solid material will.
  • the for heat dissipation of the drill head serving grooves are preferably milled out.
  • the pre-cut edge training, arch-shaped pre-cutter one has a wedge-shaped cross-sectional shape, that of a formed on the back of the shell wall hollow surface is.
  • the jacket wall recesses according to the invention preferably extend to the pre-cut edge, which is due to the wedge-shaped cross-sectional shape of the arched running pre-cutter tooth-like pre-cutter segments be cut free.
  • the tooth gap-like Structure of the pre-cut edge is also counteracting heating of the drill head during drilling. It is also advantageous that the free cut surfaces
  • the main cutting edge levels are that, in essence cut the respective hollow surface at right angles.
  • the aforementioned openings open into these cut-out areas Chip channels of the cylinder head drill.
  • the pre-cut edge in the area between two neighboring ones Grooves have a free cut.
  • the tooth gap-like Pre-cut edge sets due to this training during the drilling process only point by point on the one to be processed Workpiece on. Through the selected free cut in the area of a cut free between two adjacent grooves Pre-cut tooth is an improved one Cutting property in the area of the pre-cut edge and secondly given less warming.
  • the bulges from radial protruding tooth sections of individual teeth are. These individual teeth are wall-outer arranged of the drill head and form the pre-cut edge. Due to the radially protruding arrangement of the individual Teeth are preferably axially aligned between them Freedom created. For this purpose, it is further provided that the individual teeth are made of hard material and in receiving pockets of the drill head with radial and axial protrusion are soldered. The cylinder head drill is consequently in successive operations produced. First, the drill head is with its main cutting edge and the one that penetrates the drill head at an angle Chip channels in one piece from solid material worked out.
  • the individual teeth have a cross section of the receiving pocket corresponding cross-section, whereby after Insert a single tooth with a wall clearance in the receiving bag lies in. In the space thus formed can be after heating the pre-assembled The silver solder used for final fixation of the individual teeth.
  • Fig. 1 designed as a Forstner drill cylinder head drill 1, which essentially consists of a Clamping shank 2 and a drill head carried by this 3 composed.
  • the latter is essentially circular cylindrical and has an essentially diametrically over the entire circular cross-section extending main cutting edge 4 with a centering tip 5.
  • the main cutting edge 4 is through the centering tip 5 interrupted, with each major cutting section 4 'and 4' 'towards the outer wall 6 of the drill head 3 Open chip channel penetrating the drill head 3 at an angle 7 connects.
  • Each outer wall end of the main cutting edge 4 one closes with the circumference of the drill head 3 coincident pre-cut edge 8, which for Guidance of the drill 1 is used.
  • Each pre-cut edge 8 extends from the end of the main cutting edge 4 to to the edge of the other chip channel 7. Conditional due to the essentially circular cylindrical design the drill head 3 thus result in a cylindrical shape curved pre-cut edges 8.
  • the rear of the jacket wall 6 is assigned in each case a pre-cut edge 8 a hollow surface 9 is formed. This results in one, the pre-cut edge 8 forming, arcuate roughing cutter 10 with a wedge-shaped cross-sectional shape (cf. Fig. 4).
  • the main cutting edge 4 or the main cutting edge sections 4 'and 4' ' have free cut surfaces 11, which are flat and continuously up to the hollow surface 9 of each in the direction of rotation following pre-cutter 10, the open spaces 11 with respect to a transverse plane of the Drill head 3 inclined by an angle of approx. 30 ° each are.
  • the chip channels 7 have an arcuate rounded Chip channel base. Each chip channel 7 projects into the drill head its associated main cutting edge section 4 ' and 4 ''. The arched chip channel base protrudes here to the free area 11 of the other main cutting edge section inside.
  • the planes of the free cut surfaces 11 essentially cut the respective hollow surface 9 in a right Angle.
  • the otherwise smooth-walled jacket wall 6 is in the 1 to 4 shown first embodiment interrupted by grooves 12 of circular arc shape in cross section. As a result, radial bulges 13 are formed, which in this first embodiment Form shell wall recesses.
  • the grooves 12 are, for example, by means of one Finger cutter or the like in the jacket wall 6 incorporated, the orientation of the grooves 12 so can be chosen to be parallel to the drill axis run x-x. However, as can be seen in particular in FIG. 2, an orientation is preferred in which the Grooves 12 are aligned inclined to the axis x-x. By doing The embodiment shown here is an angle alpha of approx. 20 °.
  • the grooves 12 are open on both sides, that means they extend in the axial direction considered total drill head height, which is due to the wedge-shaped cross-section of the pre-cutter 10 isolated, tooth-like pre-cutter segments 14 train.
  • In the area of the penetration of grooves 12 and pre-cutters 10 are elliptical Open cuts 15.
  • each pre-cut edge 8 is in the area between two adjacent grooves 12, that is in the area of one Pre-cutting segment 14 provided with a free cut 16, with which the pre-cut edges 8 only selectively touch the workpiece to be machined.
  • a Forstner drill 1 is shown, which is the same the first embodiment with bulges 13 in Form of grooves 12 provided in the region of the jacket wall 6 is. However, here is an essentially rectangular one Cross-sectional shape of the grooves 12 selected. Are further the grooves 12 aligned parallel to the drill axis x-x.
  • These grooves 12 are also open on both sides, which in turn is in the area of the pre-cut edges 8 isolated, tooth-like pre-cutter segments 14 train.
  • Free cuts 15 formed.
  • the bulges 13 and grooves 12 are continuous, that means open on both sides. It However, versions are also conceivable in which the Bulges 13 closed on one or both sides are trained.
  • the bulges 13 and grooves 12 only serve to reduce the heat development in the area of the drill head 3 and not for chip evacuation. The latter takes place over the essentially centrally arranged Chip channels 7. This can result in the formation and alignment of the bulges 13 freely chosen will.
  • FIGS. 8 to 10 A third embodiment of the invention Solution is shown in FIGS. 8 to 10. opposite the previously described embodiments are here the jacket wall 6 of the drill head 3 is not groove-like Bulges interrupted. Rather is training chosen here so that the bulges 13 from radial protruding tooth sections of individual teeth 17 are formed are. Accordingly, the jacket wall 6 is not of Depressions but interrupted by protrusions.
  • the individual teeth 17 consist of a hard material and are accommodated in pockets 18 of the drill head 3.
  • the receiving pockets 18 are in the radial outside area the pre-cutter 10 for the outer casing wall and End face of the drill head 3 is open, and have a dovetail-shaped cross section.
  • the individual teeth 17 have an insertion cross section the receiving pockets 18 adapted cross-section on.
