Ukuthenga isethi yokuprakthiza kongela imali futhi—njengoba njalo kungena ohlotsheni oluthile lwebhokisi—kukunikeza isitoreji esilula 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 wokubhola - 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, edizayinelwe ukusetshenziswa ngokhuni futhi enethiphu elincane, elicijile elivimbela ukubhoboza ukuthi kunganyakazi (okubuye kwaziwe njengokuhamba).Amabhithi amatshe alandela iphethini efanayo ukuze asonte ama-drill, kodwa abe nethiphu ethintekayo ebambe iqhaza ebanzi, eyisicaba.
Uma sekungaphezu kwe-intshi ububanzi, ukubhoboza 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. lezi zisika indingilizi yezinto.Ezinkulu zingasika izimbobo ngamasentimitha amaningana ububanzi ngokhonkolo noma amabhuloki e-cinder.
Izinsimbi eziningi zokubhoboza zenziwe ngensimbi yesivinini esikhulu (HSS) .Akubizi, kulula ukukhiqiza imiphetho ebukhali yokusika, futhi ihlala isikhathi eside.Ingathuthukiswa ngezindlela ezimbili: ngokushintsha ukwakheka kwensimbi noma ukuyigcoba 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 yizinga kunoma iyiphi ikhithi yasekhaya.Uma uyephula eyodwa, noma uma unezidingo ezithile ezingaphezu kobubanzi bayo, ungahlala uthenga okunye okuhlukile.Isethi encane yezingcezu zamatshe ingenye isisekelo se-DIY.
Ngaphandle kwalokho, yisisho sakudala esimayelana nokuba namathuluzi afanele omsebenzi.Ukuzama ukuvivinya umzimba okungalungile ukuze wenze umsebenzi kuyakhungathekisa futhi kungonakalisa okwenzayo.Azibizi, ngakho-ke kufanelekile ukutshala ohlotsheni olufanele.
Ungathenga isethi eshibhile yokuprakthiza ngamarandi ambalwa, futhi ngezikhathi ezithile uzenzele wena, nakuba ngokuvamile kuvama ukuba buthuntu ngokushesha.Ngeke sincome izingcezu zamatshe ezisezingeni eliphansi—ngokuvamile, azisizi ngalutho.Izinhlobonhlobo zamasethi ezimbotshana zokubhoboza zekhwalithi ephezulu zitholakala ngama-$15 kuya ku-$35, okuhlanganisa nezingcezu ezinkulu ze-SDS zomasa.Intengo ingafinyelela kuma-cobalt amakhulu angu-100.
A. Kubantu abaningi, mhlawumbe akunjalo. Ngokuvamile, asethwa ku-118 degrees, okuyinto enhle okhunini, izinto eziningi eziyinhlanganisela, nezinsimbi ezithambile njengethusi noma i-aluminium.
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.Ibhuthi yerabha 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.
U-Bob Beacham ungumbhali we-BestReviews.I-BestReviews yinkampani ebuyekeza umkhiqizo enomgomo: ukusiza ukwenza izinqumo zakho zokuthenga zibe lula futhi wonge isikhathi nemali.I-BestReviews ayikaze yamukele imikhiqizo yamahhala evela kubakhiqizi futhi isebenzisa izimali zayo ukuthenga yonke imikhiqizo ewubuyekezayo.
