Yiziphi izingxenye ze-drill bit?

Ithiphu yokubhoboza
	Ithiphu le-auger lisiza ukugcina ibhithi imaphakathi ukuze ibhoboze ngokunembile emgqeni oqondile. Amathiphu e-Auger bit enziwa nge-spurs kanye nesikulufu sokuhola noma i-gimlet, ngalinye lifanele injongo ehlukile.
	Isikulufu somhlahlandlela Izikulufu zikamhlahlandlela zidonsa i-drill ngokhuni njengoba i-drill izungeza, okusho ukuthi umsebenzisi akudingeki asebenzise amandla amaningi abheke phansi ukuze abhoboze imbobo.
	Izikulufu zomhlahlandlela ziyatholakala kumageji entambo amabili ahlukene. Isikulufu sokuqala, esimahhadla, intambo enolaka esebenza kahle ngezinkuni ezithambile. Intambo ebanzi ikunikeza isilinganiso sokuphakelayo esisheshayo, okusho ukuthi ungakwazi ukubhoboza ukhuni oluthambile ngenani elisheshayo. Isikhala esibanzi phakathi kwemicu siphinde sisho ukuthi isikulufu sokuhola mancane amathuba okuthi sivaleke ngemfucumfucu yokhuni.
	Esesibili, isikulufu esincanyana singcono kakhulu sokhuni oluqinile, olunokwakheka okunwebeka kakhudlwana futhi okufanele lubhoboze ngesivinini esiphansi. Le ntambo enhle inikeza ukubamba okuthuthukisiwe.
	ichashazi le-gimlet Uma isetshenziswa kumshini wokubhoboza noma umshini wokubhoboza kagesi, izikulufu zokuhola kwesinye isikhathi zingaba nolaka kakhulu futhi zidonse i-drill ocezu lokhuni, zidale umonakalo ngenxa yokusika ngokushesha okukhulu. Amabhithi e-Auger ane-drill bit afaneleka kakhulu kulolu hlelo lokusebenza njengoba avumela umshini ukuthi ugxile ngaphandle kokudonsa kwentambo eyengeziwe (nakuba izingcezu ezinezikulufu zokuhola zingasetshenziswa - qaphela!).
	Barefoot Ama-drill bits angenayo i-gimlet noma isikulufu sokuhola ekugcineni abizwa ngokuthi "angenalutho" noma ngezinye izikhathi "angenalutho". Azijwayelekile futhi zithembele ezindaweni endizayo nezisikayo ukuze ziziqondise endaweni yokusebenza ngendlela eqondile. Ukungabikho kwesikulufu sokuhola kuphinde kubavumele ukuthi banqume izimbobo ngephansi eliyisicaba, okunenzuzo yokuthi phansi kwembobo kuzobonakala ku-workpiece eqediwe (njenge-desktop ehlelekile).
	I-Spurs I-Spurs, eyaziwa nangokuthi "izimpaphe", inesibopho sokusika umjikelezo wangaphandle wembobo ngaphambi kokuba imiphetho iqale ukubhoboza yonke enye. Lokhu kuvimbela ama-splinters lapho i-drill ingena endaweni yokhuni futhi igcina imiphetho yembobo icocekile futhi ibushelelezi.
Gcoba izindebe
	Imihlathi isika impahla embobeni ngokuyiphakamisa futhi iyiphushele phezulu iphinde iphume embobeni ehambisana nekhoyili. Ngezinye izikhathi babizwa ngokuthi "abasiki".
	Inani lamaphethelo kubhithi ye-auger lincike ekutheni indiza inokusonteka okukodwa noma okukabili (bona ngezansi). Izikulufu zendiza eyodwa zinomkhawulo owodwa, kuyilapho izikulufi zendiza ezikabili zinamabili.
I-Drill bit
	Ukundiza kwe-auger bit yi-helical twist noma i-whirl lapho udoti uphuma khona. Indiza ingaba eyodwa noma kabili.
	Amabhithi omtshingo owodwa avame ukuba namandla kancane futhi aqine, futhi umtshingo we-helical obanzi ogijima ubude bebhithi uvumela ukukhishwa kwe-chip okungaphezulu kunezinsimbi zomtshingo ezimbili. Lokhu kusho ukuthi akudingeki ukuthi zikhishwe emthonjeni kaningi ukuze zihlale zihlanzekile.
	Ama-twist bits asika izimbobo ezihlanzekile nezibushelelezi ngoba anomkhawulo wesibili owenza izindonga zembobo zibe bushelelezi. Ngaphezu kwalokho, ukuzungezisa kwesibili kubangela indawo engaphezulu yebhithi esele ixhumene nendawo yokusebenza ngenkathi kubholwa, kunciphisa ubungozi bokudlidliza okuyingozi okungaholela ekuhlanekezeleni noma emigodini emikhulu.
I-Auger kancane
	Izinto ezakha i-helix ku-auger bit ngezinye izikhathi zibizwa ngokuthi "iwebhu". Lapho iwebhu iba mkhulu, i-auger iqina.
Geza i-shank
	I-shank yingxenye ye-drill engena ku-drill. I-Drill bit shanks imvamisa iyisikwele ngesimo njengoba enzelwe ukusetshenziswa nezinsimbi zezandla. Angasetshenziswa kumadrayivu emishini, nakuba ungase ukuthole kunzima ukuwafaka ku-chuck yemihlathi emithathu.
