Chitoliro chobowola, mawonekedwe ofupikitsidwa a chitoliro chobowola dzenje, ndi mtundu wa ndodo yakunja yobowola.Amagwiritsidwa ntchito kwambiri pobowola rotary percussive yomwe imakhala ndi mpweya ndi zakumwa.Zigawo zake zazikulu ndi chitoliro (ndodo) thupi ndi olowa.
Chitoliro chathu chobowola pansi chimapangidwa motengera miyezo ya API.Ndipo malinga ndi zofunikira zenizeni, timaperekanso mtundu uwu wa chitoliro chobowola muzinthu zosiyanasiyana zaku China ndi America.
Ponena za ubwino wake, ili ndi mawonekedwe olimba kwambiri, mphamvu yosindikiza bwino, mawonekedwe akunja akunja, ndi torque yochepa ndi kukana pamene ikuzungulira.
Pankhani yoyikamo, mtolo wa mapaipi obowola amapakidwa ndi seti imodzi yachitsulo, ndipo mtolo udzakhala ndi mapaipi 9 mpaka 40 obowola.
