Drill bitsanowanzo shandiswa mumaindasitiri ekuchera mashandisirwo kugadzira cylindrical makomba mune akasiyana zvinhu zvakaita sesimbi, huni, uye plastiki.Iwo anosanganisira kutenderera kunocheka kumucheto kwakasungirirwa kune shaft inofambiswa nemuchina wekuchera.Madhiri ekudhiraivha anoshandiswa zvakanyanya mumaindasitiri mazhinji, kubva kumigodhi nekuvaka kusvika kuoiri nekuongorora gasi.
Kune akawanda marudzi eku drill bits anowanikwa, rimwe nerimwe rakagadzirirwa chaiwo zvinhu uye zvinodiwa zvekushandisa.Mamwe emhando dzakajairika anosanganisira twist drills, spade bits, uye auger bits.Twist drillsanoshandiswa kuchera kuita simbi, ukuwo mapadza nemauger bits zvichizivikanwa mukugadzira matanda.Mamwe marudzi ezvibooreso anosanganisira hole saws, step drills, countersinks, uye reamers.
Imwe yeanonyanya kukosha maitiro ekusarudza dhiri dhiri kuumbwa kwayo kwezvinhu.Zvishandiso zvakasiyana zvine madhigirii ekuoma, abrasiveness, uye kupisa kupisa, izvo zvese zvinogona kukanganisa zvakanyanya kushanda uye hupenyu hwechibhorani.Zvimwe zvezvinhu zvinonyanyo shandiswa mukudhirowa zvinosanganisira simbi inomhanya, cobalt simbi, carbide, uye diamond.
Hurefu hwehupenyu hwechibooreso chinhu chakakosha kutariswa mumaindasitiri ekuchera mashandisirwo.Mushure mezvose, mabheti ekuchera ane hupenyu hupfupi anogadzira yakakosha nguva yekudzikira uye mari yekugadzirisa.Kupokana uye kupisa kunogadzirwa panguva yekuchera kunogona kukonzera kukuru kupfeka uye kubvaruka pamucheto wekucheka kweiyo bhiti, zvichitungamira mukudzikisira kugona uye kutadza kupedzisa.Kuti uwedzere hupenyu hwechibhorani, machira akasiyana-siyana uye marapirwo anogona kuiswa, senge titanium nitride kana diamond-senge kabhoni coatings.
Muindasitiri yezvicherwa,drill bitszvakakosha pakuongorora, kuchera, uye kuchera mineral.Mabhiti anodhirowa akagadzirirwa kutsungirira nharaunda yakaoma yepasi pevhu anofanirwa kubaya nemumatombo nevhu zvine mutsindo.Marori mahombe akashongedzerwa madhirigi epamusoro anofambisa kutorwa kwemaminerari nekuunganidza data re geological uye kuchera munzvimbo chaidzo.
Mukutsvagisa oiri negasi, kuchera kwakananga inzira yakajairika inoshandiswa kubvisa zviwanikwa kubva pasi pepasi.Directional drill bits yakagadzirirwa kufamba yakachinjika uye yakatwasuka panguva yekuchera, ichibvumira kupinda muhomwe dzakawanda dzezviwanikwa kubva kune imwechete tsime.Iyi tekinoroji yakadzikisa zvakanyanya mutengo uye nguva yekuwana mafuta uye gasi matura.
Indasitiri yezvemuchadenga yakabatsirikawo zvakanyanya kubva mukufambira mberi kwehunyanzvi hwekudhirowa.Semuyenzaniso, mabhiti ekubooresa akashandiswa kuboora mukati memadziro akakora etitanium einjini dzejeti kana zvinhu zvisingaremi kabhoni faibha zvinoshandiswa mukugadzira ndege dzemazuva ano.Nekuwedzera kuri kuita kudiwa kwendege huru uye kuongorora nzvimbo, tekinoroji yepamberi yekuchera pasina mubvunzo ichabuda.
Mukupedzisa,drill bits ndiwo musimboti wekuchera maindasitiri, uye kufambira mberi kwavo kwakavandudza zvakanyanya kushanda uye kudhura-kubudirira kwekuchera zviwanikwa.Nekuenderera mberi kwekuvandudzwa kwezvinhu, machira, uye marapirwo, zvibooro zvinozowedzera kusimba uye zvinogara kwenguva refu.Mune ramangwana, matekinoroji ekuchera epamusoro achabuda sezvo maindasitiri ari kuramba achida nzira nyowani uye itsva dzekuwana zviwanikwa zvakakosha.
