Man/Man rod, Man/Female (M/F) Rod -Speed rod
M/F drillstiel is in alternatyf foar koppelingshulzen om it froulike diel fan 'e threaded ferbining op te nimmen as in yntegraal diel fan' e drillstiel. M/F boorstiel leveret mear stive ferbiningen en is makliker los te koppeljen
en hantearje. De servicelibben hat ek de neiging better te wêzen dan mei aparte koppelingen.
Foar ferlingstang en M/F -stielproses wurde de hjirûnder twa ferskillende soarten waarmtebehandeling brûkt om hege snelheid en krêftige perkussive boorstringkomponinten te fersterkjen om har prestaasjes en betrouberens te maksimalisearjen.
