Ngā Mīti Rōra Tricone IADC517 9.5 inihi (241mm)
Whakaahuatanga Hua
Kei te wātea mai i Haina ngā mata wiri tricone hiri TCI me te tiwhikete API me te ISO.
E ai ki te rauemi tapahi, ko te momo mata tricone he TCI (Tungsten Carbide Insert) me te Steel Tooth. Ko te IADC517 he mata tricone TCI.
Kei roto i ngā mata TCI tricone hanganga-waenga he whakaurunga tungsten carbide kaha ki ngā rarangi rekereke me ngā rarangi o roto. Mā tēnei hoahoa ka tere te keri me te roa o te hanganga tapahi i roto i ngā hanganga pakeke-waenga ki te-waenga. Mā te mowhiti-O rapa HSN ka hiritia kia roa ai te mau o te peera.
