Iiblade zayo ze-reamer ezi-8 ezinee-half” PDC cutters kunye noyilo lwe-back rack zonyusa ukusebenza kakuhle kokusika kwaye zinciphisa ukuguguleka. Ii-nozzles ezimbini kunye nee-ports ezi-4 zivumela ukucocwa/ukupholisa okugqwesileyo kwe-hydraulic. Ii-WC gauge pads ezifakwe kwi-flush-set ziqinisekisa ububanzi be-hole obuchanekileyo, ngelixa i-WC resistant abrasion matrix iphucula ukuqina.
