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.
