TE MOMO MOKA DILL
WHAKAMAHI i nga tikanga
1. Maina.
2. Te puna wai.
3. Papa hinu & Gas.
4. Te tono keri hanga.
He pai te hoahoa a Grand Rotary Grand Bits i nga hanganga kawe me nga whakauru carbide ki te tu atu i nga wero nui o nga tono maina o enei ra. Kia rite tonu mo te whakapai ake i nga hua me te whakarato i nga hua mahi nui/utu. Ko te whiriwhiri i nga hoahoa tika me te taurite i waenga i te ROP teitei (Rate of Penetration) me te oranga pai o te mahi keri e whakarite ana i te TDC pai (Tapeke Utu Keri) mo nga kaihoko.
