Sekhahla sa ho phunya ke mofuta oa sesebelisoa se ka sebelisoang bakeng sa ts'ebetso ea ho cheka, 'me ho sebelisoa ha mochine oa ho phunya ho sebetsa ha hlobo ho pharaletseng haholo;boro e ntle e boetse e ama litšenyehelo tsa ho sebetsa ha hlobo.Joale ke mefuta efe e tloaelehileng ea li-drill ha re ntse re sebetsa ka hlobo??
Pele ho tsohle, e arotsoe ho ea ka thepa ea drill bit, eo hangata e arotsoeng ka:
Li-drill tsa tšepe tse lebelo le phahameng (tse sebelisoang hangata bakeng sa lisebelisoa tse bonolo le ho cheka ka mahahapa)
Likotoana tsa ho cheka tse nang le cobalt (tseo hangata li sebelisetsoang ho sebetsana le masoba a thata joalo ka tšepe e sa hloekang le li-alloys tsa titanium)
Li-drill tsa Tungsten steel/tungsten carbide (bakeng sa lebelo le phahameng, boima bo phahameng, ts'ebetso e nepahetseng ea lesoba)
Ho ea ka tsamaiso ea li-drill bit, hangata:
Li-drill tse otlolohileng tsa shank twist (mofuta o tloaelehileng oa ho cheka)
Li-drill tsa micro-diameter (li-drill tse khethehileng bakeng sa li-diameter tse nyane, bophara ba lehare hangata bo pakeng tsa 0.3-3mm)
Ho cheka mehato (e loketseng ho etsa mohato o le mong oa masoba a mehato e mengata, ho ntlafatsa katleho ea mosebetsi le ho fokotsa litšenyehelo tsa ho sebetsa)
Ho ea ka mokhoa oa ho pholisa, e arotsoe ka:
Ho cheka ho batang ka ho toba (ho tšeloa ka ntle ho pholileng, li-drill tse tloaelehileng hangata ke li-drill tse batang ka ho toba)
Boko ea ka hare ea ho pholile (boro e na le 1-2 e pholileng ka mekoting, 'me se pholileng se feta ka masoba a pholileng, e leng se fokotsang mocheso oa mochine le mosebetsi oa ho sebetsa, o loketseng lisebelisoa tse thata haholo le ho qeta)
