X6/X7 series yog cov PDC siab kawg nrog lub zog hluavtaws ntawm 7.5-8.0GPa.
Qhov kev sim tiv thaiv kev hnav (qhuav txiav granite) yog 11.8Km lossis ntau dua. Lawv muaj kev tiv thaiv kev hnav siab heev thiab kev cuam tshuam toughness, tsim nyog rau kev khawb hauv ntau yam kev tsim los ntawm nruab nrab-nyuaj mus rau nyuaj, nrog kev hloov pauv zoo rau quartz sandstone, limestone, thiab interlayer-nplua nuj nruab nrab-nyuaj pob zeb. Cov koob X6 yog tus cwj pwm los ntawm kev khaws cia ntug siab thiab kev nrawm siab drilling.
X8 series yog lub PDC siab heev uas muaj lub zog tsim los ntawm 8.0-8.5GPa.
Qhov kev xeem tiv thaiv kev hnav (qhuav txiav granite) yog 13.1Km lossis ntau dua. Raws li kev tiv thaiv kev cuam tshuam siab, nws muaj kev tiv thaiv kev hnav siab heev thiab tsim nyog rau kev khawb hauv ntau hom kev tsim, tshwj xeeb tshaj yog hauv cov pob zeb nyuaj xws li nruab nrab-nyuaj rau cov qauv nyuaj nrog cov txheej txheem sib xyaw.
