I-311,2mm (12 1/4″) I-drill bit ene-polycrystalline cuttings, ene-hydraulic nozzles, ene-5 blades, ububanzi be-cutter obuyi-19 mm, kunye nomzimba wentsimbi wokugrumba amatye aphakathi.

I-drill bit eyi-311.2mm (12 1/4″) igqwesile ekubholeni amatye aphakathi. Iziqwenga zayo ze-polycrystalline zinika ubunzima obugqwesileyo kunye nokumelana nokuguguleka, ziqinisekisa ubomi benkonzo ende kunye nokusebenza kokusika okuzinzileyo. Ii-hydraulic nozzles zisusa ngokufanelekileyo inkunkuma yamatye, zithintela ukuvaleka kunye nokugcina isantya sokubhoboza. Ngeeblade ezi-5, isasaza amandla okusika ngokulinganayo, inciphisa ukungcangcazela kwaye iphucula uzinzo. Ububanzi bokusika obuyi-19mm buphucula ukususwa kweetshiphusi, ngelixa umzimba wentsimbi unika amandla aphezulu okwakha ukumelana neemeko ezinzima zamatye. Zidibene, ezi mpawu zinyusa ukusebenza kakuhle kokubhoboza, zinciphisa ixesha lokungasebenzi, kwaye ziqinisekisa ukusebenza okuthembekileyo kwiindawo eziphakathi kwamatye.
