Ukuthenga isethi yokuprakthiza kongela imali futhi—njengoba njalo kungena ohlotsheni oluthile lwebhokisi—kukunikeza isitoreji esilula kanye nokuhlonza. Nokho, umehluko obonakala umncane wokwakheka nokokusebenza ungaba nomthelela omkhulu enanini nasekusebenzeni.
Sihlanganise umhlahlandlela olula wokukhetha isethi yokubhoboza eneziphakamiso ezithile.Okwethu ukukhetha okuphezulu, i-IRWIN's 29-Piece Cobalt Steel Drill Bit Set, ingaphatha cishe noma yimuphi umsebenzi wokumba - ikakhulukazi izinsimbi eziqinile, lapho izingcezu zokubhola ezijwayelekile zingahluleka khona. .
Umsebenzi wokubhoboza ulula, futhi ngenkathi idizayini ye-groove eyisisekelo ingashintshile amakhulu eminyaka, umumo wethiphu ungahluka ukuze uphumelele ezintweni ezihlukene.
Izinhlobo ezivame kakhulu ama-twist drill noma ama-rough drill, okuyinketho enhle nxazonke.Ukwehluka okuncane i-brad tip drill, eklanyelwe ukusetshenziswa ngokhuni futhi inethiphu elincane, elicijile elivimbela ukubhoboza ukuhamba ( okubuye kwaziwe njengokuhamba).Amabhithi amatshe alandela iphethini efanayo ukuze asonte ama-drill, kodwa abe nethiphu ebanzi, eyisicaba ukuze abambe amandla omthelela aphezulu ahilelekile.
Uma sekungaphezu kweyintshi ububanzi, ukubhola okusontekile akusebenzi.I-drill ngokwayo ibe nzima kakhulu futhi yaba mkhulu.Isinyathelo esilandelayo i-spade drill, eyisicaba enezikhonkwane ezinhlangothini zombili kanye nephoyinti le-brad phakathi. ziyasetshenziswa futhi (zikhiqiza imigodi ehlanzekile kunezicucu zamafosholo, kodwa zibiza ngaphezulu), enkulu kunazo zonke ibizwa ngokuthi amasaha embobo.Esikhundleni sokubhoboza imbobo ngendlela evamile, lezi zisika indingilizi yezinto.Enkulu kakhulu ingasika imigodi ngamasentimitha amaningana ububanzi ku-concrete noma ama-cinder blocks.
Ama-drill bits amaningi enziwe ngensimbi enesivinini esikhulu (HSS).Ayibizi, kulula ukukhiqiza imiphetho ebukhali yokusika, futhi ihlala isikhathi eside kakhulu.Ingathuthukiswa ngezindlela ezimbili: ngokushintsha ukwakheka kwensimbi noma ukuyimboza ngezinye izinto. .Izinsimbi ze-Cobalt ne-chrome vanadium ziyizibonelo zangaphambili.Zingaba nzima kakhulu futhi zingagugi, kodwa zibiza kakhulu.
Izindwangu zithengeka kakhulu ngenxa yokuthi ziyizingqimba ezincanyana emzimbeni we-HSS.I-Tungsten carbide ne-black oxide iyathandwa, njengoba kunjalo nge-titanium ne-titanium nitride.Izinsimbi zokubhoboza ezihlanganiswe ngedayimane zengilazi, i-ceramic kanye nezingcezu ezinkulu zamatshe.
Isethi eyisisekelo yamabhithi e-HSS ayishumi nambili kufanele abe ajwayelekile kunoma iyiphi ikhithi yasekhaya.Uma wephula eyodwa, noma uma unezidingo ezithile ezingaphezu kobubanzi bayo, ungahlala uthenga enye ehlukile.Isethi encane yezingcezu zamatshe enye i-DIY. okuyisisekelo.
Ngaphezu kwalokho, yisisho sakudala esimayelana nokuba namathuluzi afanele omsebenzi. Ukuzama ukuvivinya umzimba okungalungile ukwenza umsebenzi kuyakhungathekisa futhi kungonakalisa okwenzayo. Awabizi, ngakho-ke kuhlale kuwufanele ukutshala imali uhlobo olulungile.
Ungathenga isethi eshibhile yokuprakthiza ngamarandi ambalwa, futhi ngezikhathi ezithile uzenzele wena, nakuba ngokuvamile kuvama ukuba buthuntu ngokushesha.Ngeke sincome izingcezu zamatshe ezisezingeni eliphansi—isikhathi esiningi, azinalusizo lwalutho.Izinhlobonhlobo zekhwalithi ephezulu amasethi we-drill bit yenhloso evamile ayatholakala nge-$ 15 kuya ku-$ 35, kufaka phakathi izingcezu ezinkulu ze-SDS.Intengo ye-cobalt iphezulu, futhi amasethi amakhulu angafinyelela ku-$ 100.
A. Kubantu abaningi, mhlawumbe akunjalo. Imvamisa, abekwe ku-118 degrees, alungele ukhuni, izinto eziningi eziyinhlanganisela, nezinsimbi ezithambile njengethusi noma i-aluminium. , i-engeli engu-135 degree iyanconywa.
A. Kuwubuqili kancane ukusebenzisa ngesandla, kodwa kunezinhlobonhlobo zezinto zokugaya noma izinsimbi zokucija ezihlukene ezitholakalayo.Izimbobo zeCarbide kanye ne-titanium nitride (TiN) zidinga isishicileli esisekelwe idayimane.
Esikuthandayo: Ukukhethwa okubanzi kosayizi abavamile kukhasethi lokudonsa elilula.Shisa futhi ugqoke i-cobalt engazweli impilo eyengeziwe yesevisi.I-angle engu-135-degree inikeza ukusika kwensimbi okuphumelelayo.I-Rubber boot ivikela ikesi.
Esikuthandayo: Inani elikhulu, inqobo nje uma uqonda ukulinganiselwa kwezingcezu ze-HSS.Ihlinzeka ngezinsimbi kanye nezishayeli zemisebenzi eminingi ezungeze ikhaya, igaraji nengadi.
Esikuthandayo: Kunezicucu ezinhlanu kuphela zokubhoboza, kodwa zinikeza osayizi bezimbobo ezingu-50. I-Titanium enamathelayo ukuze ihlale isikhathi eside.Idizayini egxile kuzo wena uqobo, ukunemba okuphezulu.Amaflethi aku-shank avimbela i-chuck ukuthi ingasheleli.
