I kii nga kaihoko mai i tawahi kei te raru ratou ki te Sprial Drill Rod e whakamahia ana inaianei.He nui ake te diameter o te poka i te mokamoka.
Gimarpol'I akohia e te miihini tenei keehi, ka hangaia he tauira hou mo te Spiral Drill Rod mo te kaihoko.A whakaoti i tenei raruraru i te wa.
He pai to mahi, Gimarpol's engineer!Kia ora!!!
