Te rākau whakanui PDC wing e whakamahia mo te tūranga whakanui he whakamua nui i ngā mahi whakanui, e hīkina nei ngā whakaawe ā-mata ki te whakapai i te noho me te wehewehe i ngā mahi whakanui. Ko te rākau whakawai kēnei e mau ana i ngā hiku kē, e tūhono ana ngā kutu PDC ki runga i te whakapae whatitiri, e whakamana ana i te whakanui i te whenua me te akiaki. Ko te whakapae whatitiri o te rākau e hanga ana he pūtake rangatira mō te wheako whakawai e taea ai te whakanui i te wehi, ā, e whakatatū ana i te haere tonu. E hanga ana ēnei rākau i ngā paiaka whai mana, e whakauru ana ngā kutu PDC (polycrystalline diamond compact) e whakamana ana i te wehi hei whakakaha i te wehenga me te wehenga whakanui. Ko te hanga hiku e whakawhanake ana i te wehenga akiaki e hanga ana i te huringa waiwhitinga ki waho i te rākau, e whakaiti ana i te whakapae akiaki me te whakamahi wehewehe. Ko te whakatakotoranga o te rākau kei te whai mana hei whakamahi i ngā momo whenua e rerekē ana, mai i ngā whenua māku ki ngā whenua kotahi-kotahi, me te whakaritea i tēnā ka whai mana mō ngā mahi whakanui e rerekē ana. Nā ngā mahi hanga matua e whakamana ana i te tūranga kutu me te whakapai wheako, e whai ake ana i te whakapai i te ratemai whakanui (ROP) me te whakatīmata i te oranga o te rākau. Ko te hanga rākau PDC wing e whakauru ana i ngā whiuwaka matua e whakamana ana i te whakamahi wai mō te whakamātau me te whakakī i te wehenga, e whakamana ana i te wehenga pai i ngā tikanga whakanui e hē ake ana.

Te kōwhai PDC rara pūtake whakamahia e te kōwhai i waenganui o ētahi nuinga hiranga e hāngai ana ki ngā mahi herehere moana. Tuatahitia, ko tōna hoahoa kōwhai taketake e whiwhi ana i ngā hiranga paihere mō te wehewehe i te wāhi ka whakapuaki i te take (WOB) ahakoa i te whakatika pai o ngā ratonga penepene. Ko tēnei e huri ana i ngā utu mahi me te itinga i te whakahaere o ngā whakawhitinga. Ko te whakaahua rara o te kōwhai e hanga ai he mahi kutikuti rerekē ake ahakoa i te iti iho i ngā whiuwhiu, e hīkina nei i te whakahaere pai me te whakatinanatanga paihere o te wehewehe. Ko te whakatakotoranga paihere o ngā kutikuti PDC ki runga i ngā kōwhai e tiakina nei i te whakahaere paihere, e whakatipu ana i te oranga o te kōwhai mō te wā e whakahaere ana. He hiranga atu anō hoki ko te paihere o te kōwhai i te tino taea i te tahae, e whakaae ana ki te whakarite paihere o ngā ara wai. Ko tēnei kaitono e whakamutu ana i te kōwhai balling me te tino taea i te whakahaere paihere i waenganui i ngā momo whenu. Ko te hoahoa o te kōwhai e whakaae ana hoki ki te whakatipu paihere o te arahi, e whaihua ana i te mahi arahi mō ngā tono arahi. Ko te whakahaere paihere o te mamae ā-huarahi, e whiwhi ana i te whakahaere paihere ā-wai, e whakamutu ana i te whakapakuhere me te whakatipu i te oranga o te kutikuti. Ko te whaiwāhi o te kōwhai mō ngā momo whenu e rerekē ana e iti ana i te tino taea i ngā putanga kōwhai, e whakamutu ana i te wā e whakahaere ana i ngā kōwhai, e whakatipu ana i te wā e whakahaere ana i te wā e whakahaere ana i te wā e whakahaere ana i te wā. Ahakoa i te nuinga hiranga, ko te tino taea o te kōwhai PDC rara i te whakahaere paihere i te wā e whakahaere ana i te wā e whakahaere ana i te wā e whakahaere ana i te wā. Ko te iti iho i ngā whiuwhiu e whakamutu ana i te paihere o te rua o te rua me te itinga i te tino taea i te whakahaere paihere.

Kei te whakapakari i te hanganga o te tāhuhu PDC rōnaki te hoahoa o ngā hūnga o te pūtake kaiwhitiwhiti. Ko te hoahoa o ngā hūnga e whakatupu ana i te haurongo pai ki waenganui i te mahi kaiwhitiwhiti nui ake me te whakahaere wairua. Kua hangaia ngā hūnga nui rawa atu hei whakamahere i te pai o te mahi kaiwhitiwhiti, ahakoa iti ai ngā whiu kore e āheinga ana i te oranga o te pūtake me te pai o te pūtahi. Kei roto i ngā hūnga ngā mātauranga matatini o te wai, e hanga nei i ngā raraunga e āhei ana ki te tango pai o te wai me ngā kaiwhitiwhiti ki waho i te mata kaiwhitiwhiti. E ai ki tēnei hanga matatini, ka puta te whakamahere pai mo te mahi kaiwhitiwhiti, ka tohua he pai ki te kawe mai i ngā pūkorero e āheinga ana i te pai o te whitiwhiti. Ka whakangungu hoki te whakaritenga o ngā hūnga ki te whakaeke pai o te kuhu ki runga i te mata o te pūtake, ka whakaiti i ngā take kuhu me te whakatīkina i te oranga o ngā kōmponenti. Ko te paonga tika me te whakatakoto o ia hūnga e whakapai ana i te whakahaere tonu me te pai hoki o te whitiwhiti whānui.
