Chidutswa ichi cha kubowola ndi njira yoyamba yogwiritsidwa ntchito popanga zinthu zovuta kubowola ndi kukhazikika bwino, kutulutsa madzi bwino komanso kufalikira mwachangu.
• Mitundu:Mtundu wamba; Mtundu wolimbikitsidwa; Mtundu wamphamvu kwambiri.
• Mitu:Ulusi uliwonse wachikazi kapena wamwamuna.

PDC imayimira Polycrystalline Diamond Compact yomwe imatanthauza zodulira pazidutswa izi.

Ma bits a PDC ali ndi liwiro labwino kwambiri lolowera mukamabowola ndipo amatha kugwira ntchito zina m'malo oyenera.

Zodulira diamondi zimakhala zolimba kuwirikiza ka 10 kuposa chitsulo koma zimakhala zofooka ndipo zimatha kuwonongeka zikangopangidwa mopanda kusinthasintha.

Zidutswa za PDC zimakonda kuboola miyala ya shale, miyala ya dongo yamchere, konkire ndi mchenga. Pewani miyala ya miyala ndi mchenga.

Ma PDC Bits ndi chisankho chabwino kwambiri pa zitsime zodula kapena zakuya kwambiri ndipo makamaka zimapambana pobowola m'zitsime zolimba zofewa mpaka zapakati.

Zidutswa za PDC zitha kupangidwa kuchokera ku zitsulo kapena matrix bodies.

Mudzapeza dzenje lozama kuchokera ku Matrix Body koma silingathe kukonzedwa kapena kubwezeretsedwanso, chifukwa likhoza kusweka ngati chobowoleracho chikhudza gawolo mwamphamvu.

Chidutswa cha PDC cha thupi lachitsulo ndi cholimba kwambiri kuposa thupi la matrix ndipo sichingasweke. Sichingaboole mozama kwambiri koma chikhoza kukonzedwanso ndikusinthidwanso.

Mukamaboola ndi ma bits a ProDrill PDC, ndikofunikira kudziwa malangizo athu okhudza kulemera komwe kumalimbikitsidwa pa drill bit komanso kuwongolera liwiro lozungulira.
