Tá ábhair diamanta polycrystalline, le húsáid i giotáin dhlúth Diamond polycrystalline (PDC), ar cheann de na dul chun cinn ábhartha is tábhachtaí maidir le huirlisí druileála ola le blianta beaga anuas.Rothlaíonn giotáin chinn sheasta mar phíosa amháin agus ní bhíonn aon pháirteanna gluaiste ar leithligh iontu.Nuair a úsáideann giotán ceann seasta gearrthóirí PDC, tugtar giotán PDC orthu go coitianta.Tá méadú seasta ar an éileamh atá ar ghiotáin ag baint úsáide as gearrthóirí PDC, agus tá siad beagnach chomh coitianta le giotán cón sorcóir i go leor feidhmeanna druileála.
