Abstract

Både for å bedre boreytelsen og forenkle produksjon, består et borehode av en rørstuss (1) med en innvendig gjenge (4) for befestigelse til en borestang e.l., hvis ene ende er utstyrt med en borkrone (2), hvor borkronen (2) utgjøres av en direkte på rørstussens (1) frontende anbragt anordning av enkeltvise, i tverrsnitt kvadratiske skjærlegemer (3, 3', 3") som er anordnet i form av en pil, slik at det strekker seg et skjærelement med tverrsnittsplanet som inneholder rørstussens (1) frontside, og hvor dets ene spiss (8) befinner seg i området ved rørstussens (1) akse (5). Skjærlegemene er fast forbundet med rørstussen (I) og minst én spyleåpning (10) er avgrenset i borehodets frontside ved mellomrom mellom skjærleger. Skjærlegemene er utformet av det samme materiale som rørstussen (1) og består av stål, idet området ved borkronen (2) er herdet.Both to improve drilling performance and simplify production, a drill head consists of a pipe socket (1) with an internal thread (4) for attachment to a drill rod or the end of which is equipped with a drill bit (2), the drill bit (2) being constituted of a device, arranged directly on the front end of the pipe nozzle (1), of individual, cross-sectional, square cross-sections (3, 3 ', 3 ") arranged in the form of an arrow, so as to extend a cutting element with the cross-sectional plane containing the pipe nozzle (1). ) face, and where its one tip (8) is in the region at the axis (5) of the pipe socket (5). The cutting bodies are firmly connected to the pipe socket (I) and at least one flush opening (10) is delimited in the front side of the drill bit at intervals between shear doctors. The cutting bodies are formed of the same material as the pipe socket (1) and are made of steel, the area at the bit (2) being hardened.
