PDC bit yomwe idagwiritsa ntchito kuboola mafuta/gasi mozama, migodi ya miyala yolimba, kuboola zitsime za geothermal, ndi mapulojekiti akuluakulu omanga nyumba.

1. Kukana Kwapadera kwa Kuvala Kolimba Yopangidwa ndi tungsten carbide matrix yolimba kwambiri, chidutswachi chimapirira kukwawa kwambiri m'miyala yolimba (monga granite, quartzite) ndi malo opanikizika kwambiri/kutentha kwambiri (HPHT). Chimachepetsa kuwonongeka kwa zidutswa ndi 30%+ poyerekeza ndi zidutswa za matrix wamba, ndikuwonetsetsa kuti nthawi yayitali yogwirira ntchito m'mikhalidwe yovuta yobowola.

2. Kugwira Ntchito Bwino Kwambiri Pobowola ndi Kulowa M'nthaka Kapangidwe kodulira kokonzedwa bwino kokhala ndi kapangidwe kowonjezera ka PDC cutter ndi ngodya yakumbuyo ya rake kumawonjezera kukhudzana ndi miyala yolimba. Imapereka ROP (Mlingo Wolowera M'nthaka) yokwera ndi 25-40% kuposa zidutswa zachikhalidwe za roller cone, kuchepetsa kuzungulira kwa kubowola ndikuchepetsa ndalama zobowola pa phazi limodzi.

3. Kukana Mphamvu ndi Mphamvu ya Mphamvu Kapangidwe ka thupi la matrix kolimbikitsidwa kamawongolera umphumphu wa kapangidwe kake, zomwe zimathandiza kuti chidutswacho chizitha kupirira kugwedezeka kwakukulu ndi kusinthasintha kwa mphamvu ya chingwe mu miyala yolimba yosweka. Amachepetsa kuwonongeka kwa zidutswa ndi kulephera msanga, amachepetsa kuchuluka kwa kugwedezeka ndi nthawi yosapanga (NPT).

4. Ubwino Wabwino wa Mabowo & Kukhazikika kwa Chitsime Kapangidwe ka hydraulic kapamwamba kamatsimikizira kuti kudulako kumachotsedwa bwino, kupewa kuphulika ndi kumamatira m'mapangidwe olimba. Kumasunga mulifupi ndi molunjika bwino kwa mabowo, kuchepetsa zovuta zoyendetsera chitsime ndikuwonjezera magwiridwe antchito a chitsime.
