PDC yana tsaye don ƙaramin lu'u-lu'u na polycrystalline. Ainihin, PDC bit yana amfani da waƙar lu'u-lu'u zagaye da aka haɗe zuwa tushe na carbide a matsayin tsarin yanke na farko. Lu'u lu'u-lu'u na tushen polycrystalline kuma yana da fa'idodin kasancewa mai ɗorewa da kuma kaifi da kai.

Lu'u-lu'u na roba yana da juriya sau 150 fiye da carbide. GE ne ya haɓaka, ana ba da waɗannan lu'u-lu'u galibi azaman kayan aikin roba da aka ƙirƙira a ƙarƙashin matsanancin zafin jiki da matsa lamba don yin madaidaicin wafern lu'u-lu'u.


Tsarin leaching da sinadarai yana kawar da abin da ke haifar da cobalt daga microstructure na PDC. PDC leaching lu'u-lu'u mataki ne mai mahimmancin tsari wanda ke ƙara tsayin tsayi da aikin bit.

Ana haɗa wafers ɗin zuwa tushen carbon. Wannan tushe na carbide yana aiki ayyuka biyu. Na farko, suna samar da ingantaccen tsari don tallafawa wafern lu'u-lu'u. Na biyu, yana ba da hanyar haɗa lu'u-lu'u zuwa jikin bitar tun da ba za ku iya siyar ko walda lu'u-lu'u ba. Manufar ita ce samar da duka mai tsinke mai dorewa yayin da ake haɓaka ƙimar shiga.


Bangaren lu'u-lu'u a cikin ma'auni na carbide na PDC bit ana kiransa cutter. Sun zo cikin manyan girma uku na diamita 13mm, 16mm, da 19 mm. PDC bit da farko yana amfani da mai yanke 1308.


Wani muhimmin mahimmanci na masu yankan lu'u-lu'u shine chamfer, wanda shine kusurwar gefen gefen lu'u-lu'u. Wannan kusurwa yana da mahimmancin mahimmanci akan ƙirar bit da aiki. Ba a saba amfani da masu yankan chamfer (digiri sifili) kuma za a yi amfani da su a ƙasa mai laushi kawai saboda suna da saurin yin guntuwa. Chamfer mai digiri 12 shine zaɓin shigar da sauri cikin sauri. Har yanzu suna da saurin yin guntuwa cikin sauƙi. Zzbetter na iya yin chamfer ta kowane buƙatun abokin ciniki.


Tushen carbide yana da mahimmanci ga aikin mai yankewa. Ana haɗe masu yankan inganci zuwa tushe masu kyau tare da madaidaicin grid. Matakan inganci mara kyau za su yi taron yankan mara kyau.
