Kei te whakamahia te pūtahi PDC DTH hei whakaū i tētahi tūponga matatau hōhonu, e kake ana i ngā momo hangarau hōhonu, e whakawhitiwhiti ana i ngā momo hangarau PDC (Polycrystalline Diamond Compact) me ngā rākau DTH (Down-The-Hole) pūtahi hōhonu. Ko tēnei take whakawai, e āhei ana ki te whakatakoto i ngā kutu PDC i runga i tētahi tinana kōwhai matua, hei whakatika i ngā mahi hōhonu nui rawa atu. Kei roto i te hangarau o te pūtahi, ko ngā momo wāhi hōhonu matua e tiakina ana i te pai o te whakapai me te mātai i te wā o te mahi, ka puta ano he tinana whakatika e āhei ana ki te whaiaro me te whaiaro. Kua hangaia ēnei pūtahi hōhonu hei whakatika i ngā momo whenua e rerekē ana, mai i ngā whenua mēngi ki ngā whenua kotahi-kīwaha, tae atu ki te whakamahere i ngā ratonga whakapiki me te whakatika i te wā o te mahi. Ki te whakaaetanga o te whakatikanga tuatahitanga o te pūtahi, ka āhei ai ki te whakahokia i te kawe hōhonu ki te tahuhu whenua, ka huihui ake i te pai o te whakapiko me te whakapai i te whenua. Ko te whakatakotoranga kutu whakahirahira e whakihirahira ana i te whakapai i te whenua, e iti ana i te whakapai, e huihui ana i ngā pohehe hōhonu me te itinga i te wā o te mahi. Hei tirohanga anō hoki te hanga o te pūtahi, e āhei ana ki te whakapai i te pai o te whakapai, e whakaiti ana i te whakapai o te pūtahi, e whakatika ana i te pai o te mahi i roto i ngā wāhanga e rerekē ana. I whakarerekētia nei te mahi hōhonu i waenganui i ngā whenua e toru, ināianei, hei whakamahere i ngā mahi hōhonu, hei whakatika i ngā mahi hōhonu me te pai o te utu.

Kei te tuku ngā taumata nui o te pūtahi whakamatakatanga PDC DTH i runga i ēnei kaupapa whakamatakatanga. Tuatahi, ko te hunga kutu PDC matua ai te hohouritanga me te whai wawanga, e hiaoa ana te oranga o te pūtahi i waenganui i ngā whakamātau whakamatakatanga kē. Ko tēnei whakapae oranga tuatahi he whakaiti haere i ngā utu whakawehe take me te iti rawa atu i te wā kua noho kore mō ngā whakarerekē pūtahi. Ko te whakaahuatanga matua o te pūtahi e whakawhiwhi ana i ngā ratonga tahuri ki te taha, kei reira i mate ai ngā toenga whakamatakatanga i raro i ngā mahi whakamatakatanga, me te whakawhanake i te pai o te kaupapa. Ko te mahi kutu pai ake o ngā kutu PDC e hiaoa ana i ngā takirua roa pai me te whakamana pai i te hanga, e whakaiti ana i te hiahia mō ngā mahi tuarua me te whakapai i te pai o te kaupapa katoa. Kei te pai anō hoki te mahi o ēnei pūtahi i roto i ngā momo whenua rerekē, kaua e hiaoa ana te hokohoko pūtahi i waenganui i ngā momo whenua kē e pa ana. Ko te whakahaere pai o te kiritaki ki te PDC DTH drill bits e whakaiti ana i te whakamahinga o te huringa, e whakangungu ana i ngā utu mahi me te whakapai i te āhuatanga taiao. Ko tō rātou rautaki wāriki matua e tirotiro ana i te pai rawa o te whakamutu me te whakawhitiwā, e whakamutu ana i ngā take whānui pērā i te pūtahi pūtake me te whakapae pai o te pūtahi. Ko te hanga anō hoki o ngā pūtahi PDC DTH e whakapai ana i te waea o te kaiwhakamahi me te whakaiti i te huringa o te take. Anō he mea nui hoki, ko te hanga matika o ngā pūtahi PDC DTH e whakapai ana i te pai o te roanga, e hiaoa ana i te hiahia mō ngā ara whakamatakatanga pai. Ko te whakaaetanga o ēnei taumata nui he tino tūranga pai mō ngā whakahaere e hiahia ana ki te whakapai i ō rātou mahi whakamatakatanga, me te whakaiti i ngā utu mahi katoa.

Teitei ake te whanake me te whakarongo ki te mate

Kei te whakamana ngā whanonga here kore o te rautaki PDC DTH i roto i tōna pūnaha matou me ngā momo hanganga. Ko te whakamahere i ngā kaiwhakahatutia Polycrystalline Diamond Compact he wāhanga korekore kē e kore e taea te whakapā, ka kitea i mua i ngā take karaidi turetu. Ka whakapuare ēnei kaiwhakahatutia ki te tinana ahuatanga nui i runga i ngā momo hokohoko whakahirahira, e whai ana i te mahi pai i raro i ngā āhuatanga whakamataku. Kua hangaia i te whāinga whakarite i ngā āhua whakamana e āhei ana ki te whakatupu i te whiu me te whakapae, e whai ai i te oranga o te rautaki. E whai ake nei i tēnei whakamana, e iti ana ngā whakawhiti rautaki, e iti ana ngā wa korenga, me te iti noa iho ngā utu whakatere here katoa. Ko te hanga kino koeke tonu anō te whakangungu i runga i te roa o te rautaki, e whai ana i te mahi pai tuatahi i te mutunga o te hiahia ki te whakakī i te rautaki hou.
