Ama-drill asontekile ngokuphelele yiwona asetshenziswa kakhulu emisebenzini eminingi yokubhoboza. Ungakhetha izinto zensimbi ezinesivinini esikhulu ezahlukene okuhlanganisa i-M42, i-M35, i-M2, i-4341 kanye ne-4241 ukuqinisekisa ukusebenza kahle kokusika kanye nokuqina. Siphinde sinikeze amazinga ahlukene okucubungula, okuhlanganisa i-DIN 338, i-DIN 340, i-DIN 1897, kanye nobude be-Jobber ukuze kuhlangatshezwane nezidingo zakho ezahlukene.
Lezi zingcezu zokubhola ezisontekile zitholakala ngezindlela ezahlukene zokuqedela, okwenza zingagcini nje ngokuba ngcono ekusebenzeni, kodwa futhi zikhange ngokwezimonyo. Uma udinga umbala ohlukile wobuso, singawuhlela ngendlela oyifisayo.
Ama-drill anezingqimba ezimbili ezihlukene: ama-degree angu-118 nama-degree angu-135, kanye nokukhetha kokwengeza imiphetho ehlukene ukuze kuhlangatshezwane nezidingo zezinto zokwakha ezahlukene kanye nezinhlelo zokusebenza. Ngaphezu kwalokho, ungakhetha ezinhlotsheni ezahlukene ze-shank njenge-shanks eziqondile eziyindilinga, i-triangular flat bottom noma i-hexagonal shanks, kuye ngezidingo zomsebenzi ezithile.
Sinikeza osayizi abavamile kusukela ku-0.8 mm kuya ku-25.5 mm, 1/16 intshi kuya ku-1 intshi, #1 kuya ku-90, kanye no-A kuya ku-Z ukuqinisekisa ukuthi ungathola kalula usayizi ofanele umsebenzi wakho. Uma udinga omunye usayizi ongenhla, sicela ukhululeke ukuxhumana nathi.
Kungakhathaliseki ukuthi usebenza emsebenzini wensimbi, ukwakha, noma kwenye insimu, ama-drill bit agcwele umhlabathi akunikeza ukusebenza okuphezulu nokuthembeka. Kungakhathaliseki ukuthi udinga ukubhoboza ngokushesha nangokunembile noma usebenza ezintweni ezikhethekile, sinemikhiqizo ehlangabezana nezidingo zakho. Uhla olubanzi lwemikhiqizo lunikeza ukukhetha okubanzi kwephrojekthi yakho, okuqinisekisa ukuthi uthola imiphumela emihle kakhulu yomsebenzi wakho. Uma ukhetha ama-drill bit agcwele umhlabathi, uthola inhlanganisela ephelele yekhwalithi ephezulu, ukuguquguquka kanye nokuthembeka.
