Whakaahuatanga:
Ko te Integral Blade Stabilizer (IBS) he whakapumau hurihuri kotahi-waahanga ka taea te whakanoho tata ki te moka, ki runga ake ranei i te aho drill. He hanga kotahi-waahanga i hangaia mai i te rino koranu kaha-kaha (ko te rino aukume te whiriwhiri). Ka aukati i te piri rerekee o te aho drill ma te whakapumau i te BHA me te pupuri i nga kara me nga paipa wiri mai i te pakitara poka. Ma tenei ka whakaiti i te wiri, te awhiowhio o te paipa keri, me te tortuosity poka wai; i tua atu, ko te whakapumautanga ka mau tonu te huarahi keri ahakoa he keri tika, he puna whakapae, he puna aronga ranei.
