Soo bandhigida qalabkeena casriga ah ee polycrystalline bits dheeman, qalabka ugu dambeeya ee goynta qodista saliidda, bixinta waxqabad heer sare ah iyo nolol dheer. Marka loo eego dhexrooryada kala duwan, PDC-gayadu waxay u qaybsan tahay taxane cabbir kala duwan sida 19mm, 16mm, iyo 13mm, iyo sidoo kale taxane cabbir yar oo caawiye ah sida 10mm, 8mm, iyo 6mm.
Dhexroorka weyn ee PDC-yada, waxaan isticmaalnaa agab leh iska caabin saameyn aad u wanaagsan, taasoo ka dhigaysa inay ku habboon yihiin isticmaalka qaababka jilicsan ee heerarka sare ee dhexgalka. Dhexroorka PDC-yada yaryar waxay u baahan yihiin iska caabin sare oo xirashada sidaa darteedna aad bay ugu habboon yihiin in loo isticmaalo qaababka adag si loo hubiyo nolosha adeeg dheer. Iyadoo aan loo eegin xajmiga, PDC-yadayadu waxay ku fiican yihiin sahaminta saliidda iyo gaaska iyo qodista, iyo codsiyada kale ee la xidhiidha.
Waxaa la soo saaray iyadoo la isticmaalayo tignoolajiyada ugu dambeysay, PDC-yadayada waxaa lagu yaqaanaa tayo sare, adkeysi iyo waxqabad hufan. Aaladaha dheemanka waxaa loo farsameeyay inay u adkeystaan xaaladaha ba'an sida heerkulka sare iyo jawiga cadaadiska sare, iyadoo la hubinayo waxqabadka ugu wanaagsan marka la qodayo qaabab adag oo lagu dhex geli karo.
Waxaan ku hanweynahay in aan ku bixinno badeecooyinka ugu sarreeya qiimaha warshadda, taas oo ka dhigaysa PDC-yada mid la awoodi karo oo la isku halleyn karo ganacsiyada nooc kasta ah. Khabiiradayada hubinta tayada waxay baaraan PDC kasta saxnaanta joomatari, halabuurka iyo qaabdhismeedka. Waxaan hubineynaa in alaabtayadu ay buuxiyaan oo ay dhaafaan heerarka warshadaha iyo rajada macaamiisha, taas oo naga dhigaysa alaab-qeybiye la aamini karo macaamiil badan oo ku qanacsan adduunka oo dhan.
Gebogebadii, PDC-gayadu waa qalab casri ah oo isku dara hal-abuurnimo, tignoolajiyada iyo tayada si loo bixiyo waxqabadka qodista aan la barbar dhigin. Nagu kalsoonow, PDC-gayadu way ka badnaan doontaa dhammaan waxyaabaha aad filayso marka la eego tayada iyo adkeysiga. Nala soo xidhiidh maanta si aad wax badan uga ogaato alaabtayada iyo adeegyadayada.
