Ukuthenga isethi yezivivinyo zokuzivocavoca kukongela imali futhi—njengoba zihlala zifika ebhokisini elithile—kukunikeza indawo yokugcina kanye nokuhlonza okulula. Kodwa-ke, umehluko obonakala uncane ngesimo kanye nezinto zokwakha ungaba nomthelela omkhulu entengo kanye nokusebenza.
Sihlanganise umhlahlandlela olula wokukhetha isethi yebhithi yokubhoboza kanye neziphakamiso ezithile. Ukukhetha kwethu okuphezulu, i-IRWIN's 29-Piece Cobalt Steel Drill Bit Set, ingaphatha cishe noma yimuphi umsebenzi wokubhoboza - ikakhulukazi izinsimbi eziqinile, lapho amabhithi okubhoboza ajwayelekile engahluleka khona.
Umsebenzi wokubhoboza ulula, futhi yize ukwakheka kwe-groove eyisisekelo kungazange kushintshe amakhulu eminyaka, ukuma kwe-tip kungahluka ukuze kusebenze kahle ezintweni ezahlukene.
Izinhlobo ezivame kakhulu ama-drill ajijekile noma ama-drill aqinile, okuyinketho enhle ezungeze konke. Umehluko omncane yi-brad tip drill, eyenzelwe ukusetshenziswa ngokhuni futhi ine-tip encane, ebukhali evimbela i-drill ukuthi inganyakazi (eyaziwa nangokuthi ukuhamba). Izingcezu zobumba zilandela iphethini efanayo nama-drill ajijekile, kodwa zine-tip ebanzi, eyisicaba yokusingatha amandla amakhulu okushaya ahilelekile.
Uma sezingaphezu kwe-intshi ububanzi, ama-drill ajikayo aba yinto engasebenzi. I-drill ngokwayo iba nzima kakhulu futhi ibe nkulu kakhulu. Isinyathelo esilandelayo i-spade drill, eyisicaba enezipikili ezinhlangothini zombili kanye nephuzu le-brad phakathi. Ama-Forstner nama-serrated bits nawo ayasetshenziswa (akhiqiza imigodi ehlanzekile kune-spade bits, kodwa abiza kakhulu), amakhulu kunawo wonke abizwa ngokuthi ama-hole saw. Esikhundleni sokubhoboza imbobo ngomqondo ojwayelekile, lawa asika indilinga yezinto zokwakha. Enkulu kunazo zonke ingasika imigodi ngamasentimitha ambalwa ububanzi ngamabhulokhi ekhonkrithi noma e-cinder.
Iningi lama-drill bits lenziwe ngensimbi yesivinini esikhulu (i-HSS). Akubizi kakhulu, kulula kakhulu ukukhiqiza imiphetho yokusika ebukhali, futhi ihlala isikhathi eside kakhulu. Kungathuthukiswa ngezindlela ezimbili: ngokushintsha ukwakheka kwensimbi noma ukuyimboza ngezinye izinto. Izinsimbi ze-Cobalt ne-chrome vanadium ziyizibonelo zalezo zangaphambili. Zingaba nzima kakhulu futhi zingagugi, kodwa zibiza kakhulu.
Izimbozo zingabizi kakhulu ngoba ziyizendlalelo ezincane emzimbeni we-HSS. I-tungsten carbide kanye ne-black oxide kuyathandwa, njengoba kunjalo nange-titanium kanye ne-titanium nitride. Izimbozo zokubhoboza ezimbozwe ngedayimane zengilazi, i-ceramic kanye nezimbozo ezinkulu zobumba.
Isethi eyisisekelo yama-bits e-HSS ayishumi nambili noma ngaphezulu kufanele ibe yinto ejwayelekile kunoma iyiphi ikhithi yasekhaya. Uma wephula eyodwa, noma uma unezidingo ezithile ezingaphezu kwamandla ayo, ungathenga enye ehlukile. Isethi encane yama-bits okwakha iyinto eyisisekelo oyenzayo.
Ngaphandle kwalokho, kuyisaga esidala mayelana nokuba namathuluzi afanele umsebenzi. Ukuzama ukwenza umsebenzi ngendlela engafanele kuyacasula futhi kungonakalisa lokho okwenzayo. Azibizi, ngakho-ke kuhlale kufanelekile ukutshala imali ohlotsheni olufanele.
Ungathenga isethi yama-drill ashibhile ngamadola ambalwa, futhi ngezinye izikhathi uzenzele wena, yize ngokuvamile efiphala ngokushesha. Ngeke sincome ama-masonry bits asezingeni eliphansi—ngokuvamile, awasizi ngalutho. Izinhlobo ezahlukene zama-drill bit sets asezingeni eliphezulu atholakala ngo-$15 kuya ku-$35, kufaka phakathi ama-SDS masonry bits amakhulu. Intengo ye-cobalt iphezulu, futhi ama-set amakhulu angafinyelela ku-$100.
A. Kwabaningi, cishe akunjalo. Ngokuvamile, zibekwe kuma-degrees angu-118, okuyinto enhle kakhulu ngokhuni, izinto eziningi ezihlanganisiwe, kanye nezinsimbi ezithambile njengethusi noma i-aluminium. Uma ubhoboza izinto eziqinile kakhulu njengensimbi ephonswe noma insimbi engagqwali, kunconywa i-engeli yama-degrees angu-135.
A. Kunzima kancane ukuyisebenzisa ngesandla, kodwa kunezinhlobo ezahlukene zemishini yokugaya noma imishini yokulola ehlukile etholakalayo. Ama-Carbide drill kanye nama-titanium nitride (TiN) drill adinga umshini wokulola osekelwe edayimane.
Esikuthandayo: Ukukhetha okubanzi kosayizi abavamile kwikhasethi elula yokudonsa. I-cobalt engashisi futhi engagugi ukuze isebenze isikhathi eside. I-engeli engama-degree angu-135 inikeza ukusika kwensimbi okuphumelelayo. Ibhuthi yerabha ivikela ikesi.
Esikuthandayo: Inani elihle, uma nje uqonda ukulinganiselwa kwama-bits e-HSS. Ihlinzeka ngama-drill kanye nabashayeli bemisebenzi eminingi ekhaya, egalaji kanye nasegadini.
Esikuthandayo: Kunezingcezu zokubhoboza ezinhlanu kuphela, kodwa zinikeza ubukhulu bemigodi engu-50. I-titanium coating ukuze ihlale isikhathi eside. Idizayini ezimele, ukunemba okuphezulu. Izicaba emgodleni zivimbela i-chuck ukuthi ingasheleli.
