I-External Chip-Avacuation Deep-Hole Drill iyithuluzi lokunemba okuphezulu eliklanyelwe ngokukhethekile izimo zokumba imigodi ejulile, elixazulula amaphuzu ayinhloko ezinhlungu zokubhoboza imbobo ejulile njengokuvala kwe-chip, ukungasimami kahle nokusebenza kahle okuphansi. Isakhiwo sayo esiyingqayizivele sangaphandle sokukhipha i-chip-evacuation siyinzuzo eyinhloko, engakhipha ama-chips akhiqizwe ngesikhathi sokubhoboza ngaphandle ngesikhathi sangempela, ukugwema ngokuphumelelayo ukunqwabelana kwe-chip emgodini wokubhoboza, ukunciphisa ukuguga kwamathuluzi kanye nokulimala kwezingcezu zokusebenza, nokuqinisekisa ukuzinza nokuqhubeka kwenqubo yokumba.
Mayelana nokukhethwa kwezinto ezibonakalayo, i-drill bit ithatha izinto eziphakeme ze-carbide, ezihlanganiswe nobuchwepheshe bokugaya obunembayo, obunikeza ukumelana okuhle kakhulu kokugqoka, ukumelana nomthelela kanye nokumelana nokugqwala. Ingakwazi ukugcina ukunemba kokumba okuzinzile ngisho nalapho icubungula izinto ezinokuqina okuphezulu (njengensimbi ye-alloy, insimbi engagqwali) kanye nezimbobo ezijulile, futhi inokuphila kwesevisi ende kunemishini evamile yokubhoboza imigodi ejulile, okusiza ukwehlisa izindleko zokushintshwa kwamathuluzi nokugcinwa kwamabhizinisi.
Umkhiqizo kulula ukusebenza futhi unokuvumelana nezimo okuqinile. Isetshenziswa kabanzi emikhakheni ehlukahlukene efana nezingxenye zezimoto, ukukhiqizwa kwesikhunta, izingxenye ze-hydraulic, izingxenye ze-aerospace kanye nokucutshungulwa kwemishini. Kungakhathaliseki ukuthi kuwumsebenzi osindayo oqhubekayo wokucubungula noma ukumba imbobo ejulile enembayo ephezulu, ingahlangabezana nezidingo eziqinile zokukhiqizwa kwezimboni, ithuthukise ukusebenza kahle kokucubungula kanye nezinga lokufaneleka lomkhiqizo, futhi ibe ithuluzi elibalulekile elibalulekile lemishini yokunemba yesimanje.
