Gawo lofunikira la trione Drill Bits Design ndi mitsinje yamadzi, popanda zomwe miyala ina yonse sinagwire ntchito monga momwe idafunira.Mitsinje yamadzi ndi njira zodutsa madzimadzi ozungulira, omwe makamaka amabweretsa zodulidwa pamwamba ndikuyeretsa mapangidwe omwe ali pansipa.Mapangidwe a mitsinje yamchenga yomwe imatsogolera madzimadzi pamtunda imasiyanitsa mitundu iwiri ya mitsinje:

1.mitsinje yamadzi yodziwika bwino yomwe imawongolera madziwa pa odula

2.mitsinje yamadzi yomwe imatsogolera madzi pansi pa dzenje.

Madzi obowola amadutsa kuchokera ku Drill String ndikutuluka kudzera mu nozzles pang'ono.Pamene imadutsa pa nkhope ya kachidutswa kakang'ono kamene kamanyamula chodulidwa chobowoledwa kuchokera ku cones ndikupita ku annulus.Mapangidwe oyambirira a miyala ya miyala amangolola kuti matope obowola atulutsidwe pakati pa pang'ono.Izi sizinali zogwira mtima kwambiri ndipo zinapangitsa kuti pakhale ma cuttings pa nkhope ya pang'ono (pang'ono mpira) ndi kukokoloka kwa cone.

Njira yabwino kwambiri yoyeretsera nkhope ya pang'ono idayambitsidwa.Madzi amadzimadzi tsopano amatulutsidwa kudzera m'mphuno zitatu za jet kuzungulira kunja kwa thupilo.Chisokonezo chopangidwa ndi mitsinje ya jet ndichokwanira kuyeretsa odula ndikulola kubowola koyenera kupitiliza.
