Ko te tikanga, ko te mama ake o te rakau, he pai ake mo te mahi keri. No reira he pai ake te mea angiangi atu i te mea matotoru mena he rite etahi atu tawhā. I tenei wa, me whai whakaaro ano hoki te kaha tuku me te kaha o te riipene, ko te tikanga ka hiahiatia te matotoru o te pakitara rakau kia nui ai te kaha. Ae ra, ina tono marietia te matotoru kia angiangi ki te whakaiti i te taumaha o te aho drill, tera ano tetahi atu tikanga ki te tiki ngongo putunga tino pai e whakamahi ana i nga tira pai ake.
Kei a Plato nga rakau drill DTH me te maha o nga hoahoa matotoru rereke mo ia diameter, he mea hanga mai i nga tira rereke rereke hei whiriwhiri. Na, i roto i te mahi o te keri mara, i raro i nga ahuatanga rereke, tera pea e hiahiatia nga momo momo rakau keri mo etahi atu tono. Hei tauira, ko nga mea matotoru me te maitai o te kounga teitei mo te keri poka o te hohonutanga toharite, penei i nga rua pupuhi; me nga mea angiangi he pai ake te karaehe rino mo te keri poka hohonu rawa, penei i te keri mo te waiariki whenua.
