Definitions

  • the invention relates to a drilling tool, namely a so-called Cylinder drill, with hard metal cutting edges. So that is a drilling tool is meant that a disk-shaped or has cylindrical head on the front and optionally also arranged a number of cutting edges on the circumference is.
  • drilling tools have mostly been used with a tool body made of tool steel and inserted in its head or soldered cutting edges made of hard metal material.
  • the conventional manufacturing process of such drilling tools with individually manufactured and used or soldered Tungsten carbide cutting is complex and costly.
  • the invention is therefore based on the object of an improved Construction of a drilling tool as discussed above Way of creating.
  • the drilling tool according to the invention therefore consists of a Tool body made of tool steel, the head of which is simple Disc is formed with a flat face. On the The end face of the tool carrier head is completely out Carbide existing cutting plate placed and through Solder or attached by gluing.
  • This carbide cutting plate has a spoked wheel-like training, is So not designed as a full disc, but with openings provided, which saves considerable carbide can be.
  • This insert can be injection molded Made of hard metal powder, which with an injection molding ability manufacturing medium is offset, as already mentioned known as a whole with molded and later only cutting edges to be produced.
  • Dowel pins can be placed in the end face of the tool body head be used in cooperation with the recesses a centering in the cutting plate when placing the same effect on the tool body.
  • the drilling tool according to the invention consists of a tool body 1 with a shaft 11 and a head 12, as well as with a cutting plate 2 placed on the head 12 Hard metal.
  • the tool body 1 consists of tool steel.
  • the shank 11 of the tool body used for clamping the tool 1 is cylindrical in the usual way.
  • the head 12 of the tool body is essentially as Plate formed, but two diametrically opposite Has recesses that serve as chip spaces, so that the plate actually on two diametrically opposite Segments is reduced.
  • the head 12 has a rear end Transition into the shaft 11.
  • the front face of the head 12 is flat and serves as a contact surface for the Cutting plate 2.
  • the cutting plate 2 has, as in the front view according to Fig. 2 can be seen, a corresponding shape with two itself diametrically opposed to a central area Quarter circle segments. As from FIGS. 1 and 2 emerges, has the cutting plate in the illustrated embodiment a central drill bit 21, two of these from diametrically opposed strip-shaped Cutting 22 and two also offset by about 90 ° Pre-cutter 23 arranged diametrically opposite one another.
  • the cutting plate 2 is used to save hard metal material also formed with two recesses 24 so that the Cutting tip body in plan view, as can be seen from FIG. 2, overall has approximately the shape of an eight.
  • each recess 24 is of an arcuate shape outer web and two these with the middle area the cutting plate 2 connecting radial or spoke-like webs limited. It is understood that the Recess 12 possibly also by another spoke-like web could be divided.
  • Each strip-shaped main cutting edge 22 is in the direction of rotation arranged radial web, and each pre-cutter 23 is on the radial web pointing counter to the direction of rotation of the respective cutting insert segment.
  • the cutting plate 2 is by gluing or soldering connected to the head 12 of the tool body 1.
  • a dowel pin 3 is used, which engages in one of the recesses 24 of the cutting plate and cooperates with it in a centering manner. It is understood that instead of just one dowel pin 3, two dowel pins application can find that on the diametrically opposite segments of the head 12 can be arranged.
