Qalabka dheemanka ee polycrystalline, ee loogu talagalay isticmaalka dheemanka polycrystalline compact (PDC), waa mid ka mid ah horumarka walxaha ugu muhiimsan ee qalabka qodista saliidda sannadihii la soo dhaafay.Qaybaha madaxa go'an waxay u wareegaan sida hal gabal oo aan ka koobnayn qaybo gooni u socda.Marka qaniinyada madaxa go'an ay isticmaalaan gooyayaasha PDC, waxaa badanaa loo yaqaan 'bits PDC'.Caannimada qashin-qubka ee isticmaalaya gooyayaasha PDC ayaa si joogto ah u koray, waxayna ku dhow yihiin inay la mid yihiin biraha rullalullaalka ah ee codsiyada qodista badan.
