Ho feta moo, li-drill tsa rona li fana ka taolo e ntle ea chip ho etsa bonnete ba ho cheka ha bonolo, ho sa sitisoe. Ho tlosoa ha chip ka katleho ho thibela chip jamming, ho fokotsa kotsi ea ho senyeha ha lisebelisoa le nako ea ho theoha. Tšobotsi ena e ntlafatsa ts'ebetso e akaretsang ea "ZJ clamp indexable BTA" ea ho cheka lesoba le tebileng, e leng se etsang hore e be se loketseng bakeng sa mesebetsi ea machining e phahameng haholo.
Mochini o sebelisa li-blade tse koetsoeng tse tsoang kantle ho naha, tse nang le ts'ebetso e phahameng ea ts'ebetso, phetoho e bonolo ea lehare, ts'ebeliso ea nako e telele ea 'mele oa seha, tšebeliso e tlase ea lisebelisoa le litšobotsi tse ling. E ka sebetsana le tšepe ea carbon, tšepe ea alloy e matla haholo, tšepe e sa hloekang, joalo-joalo.
E 'ngoe ea likarolo tse hlahelletseng tsa sehlahisoa sena ke sistimi ea eona ea ho cheka ea BTA (Boring and Trepanning Association), e netefatsang ho cheka ka nepo ha e ntse e fokotsa ho thothomela le ho ntlafatsa boleng ba masoba. Sena se etsa hore e be se loketseng bakeng sa lits'ebetso tse hlokang ho nepahala ho holimo, joalo ka indasteri ea sefofane le likoloi.
Ntle le moo, mochini oa mofuta oa ZJ clamp indexable BTA hole hole o boetse o fana ka phallo e ntle ea pholiso ho netefatsa phallo e ntle ea mocheso nakong ea ho cheka. Tšobotsi ena e thibela ho futhumala ho feteletseng le ho lelefatsa bophelo ba lisebelisoa, qetellong e fokotsa litšenyehelo le ho eketsa bokhoni.
