ʻO nā lako daimana polycrystalline, no ka hoʻohana ʻana i nā bits polycrystalline diamond compact (PDC), kekahi o nā mea waiwai nui loa no nā mea hana wili aila i nā makahiki i hala.Holoi nā ʻāpana poʻo paʻa ma ke ʻano he ʻāpana hoʻokahi a ʻaʻohe ʻāpana neʻe kaʻawale.Ke hoʻohana nā ʻoki poʻo paʻa i nā mea ʻoki PDC, kapa ʻia lākou i nā bits PDC.Ua ulu mau ka kaulana o nā bits me ka hoʻohana ʻana i nā ʻoki PDC, a ua like like lākou me nā ʻāpana roller-cone i nā noi wili he nui.
