X6 / X7 series yog high-end kev ua tiav PDC nrog lub siab hluavtaws ntawm 7.5-8.0Gpa.
Qhov hnav tsis kam (qhuav txiav granite) yog 11.8Km lossis ntau dua. Lawv muaj kev hnav siab heev thiab cuam tshuam rau qhov hnyav, haum rau drilling hauv ntau yam kev tsim los ntawm nruab nrab-nyuaj mus rau nyuaj, nrog kev hloov tau zoo rau quartz sandstone, limestone, thiab interlayer-nplua nuj nruab nrab-nyuaj pob zeb. X6 series yog tus cwj pwm los ntawm kev txiav ntug siab tuav thiab siab drilling ceev.
X8 series yog super-siab siab ua tiav PDC nrog lub siab hluavtaws ntawm 8.0-8.5GPa
Qhov hnav tsis kam (qhuav txiav granite) yog 13.1Km lossis ntau dua. Raws li kev tiv thaiv kev tiv thaiv siab, nws muaj qhov hnyav hnyav hnyav thiab tsim nyog rau kev sib tsoo hauv ntau hom, tshwj xeeb tshaj yog nyob rau hauv cov pob zeb nyuaj formations xws li nruab nrab-nyuaj mus rau hard formations nrog interlayers.
