Uma uthenga imikhiqizo ngesinye sezixhumanisi zethu, i-BobVila.com kanye nozakwethu bayo bangathola amakhomishini.
Uma ubhola into eminyene kakhulu, umshayeli wakho webhithi ojwayelekile angase angayisiki.Izinto ezinjengokhonkolo, amathayela, netshe zidinga amandla engeziwe asuka ku-drill bit, futhi ngisho nomshayeli webhithi onamandla kakhulu awanawo.Lezi zinhlobo zamaphrojekthi zidinga ukubhola kwesando okungenantambo okungcono kakhulu, okunganqamula lezi zindawo eziqinile.
Izingcezu ezihamba phambili zokushayela isando zikagesi ezingenazintambo zenza izinto ezimbili ngesikhathi esisodwa: zizungezisa ibhithi, futhi iphinikhodi kubhithi iphoqelela isisindo siye phambili bese ishaya ngemuva kwe-chuck.Amandla adluliselwa ekugcineni kwebhithi yokubhoboza.Lawa mandla asiza i-drill bit ukuthi iqobe izingcezu ezincane zikakhonkolo, itshe noma izitini, futhi imisele eku-drill bit ingasusa uthuli olukhiqiziwe.Amathiphu alandelayo ekukhetheni i-hammer drill ehamba phambili engenazintambo azokusiza ukuthi uthole ithuluzi elifanele lephrojekthi yakho.
Nakuba izinsimbi eziningi ezihamba phambili zesando zingenza imisebenzi emibili yomshayeli ojwayelekile wokubhoboza, akuzona ezawo wonke umuntu.Ngisho nezinsimbi zokubhoboza isando ezincane zinezingxenye ezisindayo ngaphakathi, okusho ukuthi zisinda kakhulu kunama-drill angenantambo angcono kakhulu.Futhi ane-torque enkulu kakhulu kunezinsimbi zokubhoboza ukukhanya, ngakho-ke uma ungawazi amathuluzi kagesi, ungamangali amandla awo.
Uma ungabholi kukhonkolo, izitini, amatshe noma amatshe, ungase ungadingi umshini wokubhoboza okungenantambo.Ungagcina imali ethile ngokusebenzisa izishayeli ezijwayelekile zamaphrojekthi amaningi.Kodwa-ke, uma uzithola uxuba ukhonkolo noma upende njalo, ungase ucabange ukuthi i-torque eyengeziwe enganikezwa yi-hammer drill izosiza ukusheshisa umsebenzi.
Izici ezilandelayo zenza ezinye izinsimbi zikagesi zigqame esixukwini.Ukuqonda ukuthi la mathuluzi asebenza kanjani kuzokusiza wenze isinqumo esinolwazi futhi unqume ukuthi uyawudinga yini omunye wale mishini yetorque.
Imibhobho yesando isetshenziselwa ukubhoboza izimbobo ebutsheni.Izingcezu zokubhoboza ezijwayelekile azikwazi ukuklwebha ingaphezulu lamathayela, izindlela zokuhamba zikakhonkolo noma izingqimba zamatshe.Lezi zinto ziminyene kakhulu emaphethelweni okusika ama-drill bits ajwayelekile.Umshini wokubhoboza isando ofakwe i-masonry bit uzongena kalula kulezi zindawo ezifanayo: umsebenzi wesando uhambisa ichopho lebhithi phezulu, ukhiqize amatshe amatshe noma uthuli lukakhonkolo, futhi ukhiphe umsele wengcezu emgodini.
Khumbula, udinga ukusebenzisa ama-masonry drill ukuze ungene kulezi zindawo.Lawa ma-drill anamaphiko kumathiphu ukusiza ukususa uthuli, futhi ukwakheka kwawo kwethiphu kuhluke kancane, njengamashizolo kunokubhoboza okujwayelekile.Ngaphezu kwalokho, uma ungakwazi ukungena ebusweni bezinto zokwakha, i-drill bit ejwayelekile izoba buthuntu noma iqhekeke cishe ngokushesha.Ungathola ama-masonry drill okufanele athengwe ngokwehlukana kumathuluzi anjalo.
Izinjini ezixutshiwe zithembele kubuchwepheshe "besikole esidala" ukukhiqiza izinjini.Lezi zinjini zisebenzisa “amabhulashi” ukuze zinike amandla amakhoyili.Ikhoyili exhunywe ku-shaft iqala ukujikeleza, ngaleyo ndlela ikhiqize amandla netorque.Mayelana nemoto, izinga layo lobuchwepheshe liphansi kakhulu.
I-Brushless motor technology isithuthuke kakhulu futhi isebenza kahle kakhulu.Basebenzisa izinzwa namabhodi okulawula ukuthumela i-current ku-coil, okubangela ukuthi uzibuthe oxhunywe ku-shaft ujikeleze.Uma iqhathaniswa nenjini ebhulashiwe, le ndlela ikhiqiza itorque enkulu kakhulu futhi idla amandla ebhethri amancane kakhulu.
Uma kufanele ubhoboze izimbobo eziningi, khona-ke ukuthenga i-brushless hammer drill kungase kubize izindleko ezengeziwe.Ukubhola kwesando okuxutshiwe kuqeda umsebenzi ngentengo ephansi, kodwa kungase kuthathe isikhathi esiningi.
Mayelana nesivinini, kufanele ubheke i-drill enesivinini esiphezulu se-RPM esingu-2,000 noma ngaphezulu.Nakuba ungase ungadingi isivinini esikhulu ukuze ubhoboze izinto zokwakha, leli jubane likuvumela ukuthi ulisebenzise njenge-drill bit ngaphandle kokubhoboza ukhonkolo nezitini.
I-torque ibalulekile futhi ngoba ungasebenzisa umshini wokubhola wesando oqinile ukuze ugoqe amabhawodi lag nezikulufu zibe izinto eziminyene ukuze ulungise amahange kakhonkolo, njll. Nokho, abakhiqizi abaningi abasasebenzisi “amaphawundi” njengemethrikhi.Esikhundleni salokho, basebenzisa “i-unit wattage” noma i-UWO, okuyisilinganiso esiyinkimbinkimbi samandla ebhithi yokubhoboza ku-chuck.Okungenani ama-drill bits angu-700 e-UWO angahlangabezana neningi lezinjongo zakho.
Okubaluleke kakhulu, abathengi bokubhola isando kufanele babeke phambili amabhithi ngomzuzu noma i-BPM.Le yunithi yokulinganisa ichaza inani lezikhathi lapho igiya lesando lisebenzisa khona i-chuck ngomzuzu.Ukubhoboza ngesando ngesilinganiso se-BPM esingu-20,000 kuya ku-30,000 kulungele izimo eziningi zokumba, nakuba amamodeli anomthwalo osindayo angase anikeze i-RPM ephansi uma kushintshwa itorque.
Ngenxa yokuthi umshini wokubhoboza isando ukhiqiza itorque eningi noma i-UWO, umsebenzisi udinga indlela yokulungisa ukuthi ingakanani le torque edluliselwa kusixhumi.Ngaphambi kokubhoboza i-fastener noma i-screwdriver ezintweni, i-torque eyeqile ingabangela ukuthi iphuke.
Ukulawula ukuphuma kwe-torque, abakhiqizi basebenzisa ama-clutch alungisekayo kumarigi abo okumba.Ukulungisa i-clutch ngokuvamile kudinga ukujiya ikhola ngaphansi kwe-chuck endaweni efanele, nakuba isikhundla sihlala sihluka kusukela kuthuluzi kuye kwelinye ithuluzi futhi kuya ohlotsheni lwezinto zokubhola.Isibonelo, ukhuni oluqinile oluqinile lungadinga izilungiselelo eziphakeme ze-clutch (inqobo nje uma izixhumi zingakwazi ukuzibamba), kuyilapho izinkuni ezithambile ezifana nophayini zidinga ama-clutch ambalwa.
Cishe zonke izinsimbi zokumba kanye nemishini yokubhoboza (kuhlanganise nezinsimbi zokubhoboza isando ezilula nezimaphakathi) zisebenzisa ama-chucks anemihlathi emithathu.Uma uzungezisa ama-chucks, ayabamba endaweni eyindilinga noma ene-hexagonal.I-three-jaw chuck ikuvumela ukuthi usebenzise i-drill bits ehlukahlukene kanye nezingcezu zomshayeli, yingakho zicishe zifane nendawo yonke kuma-drill driver.Atholakala ngosayizi ongu-1/2-intshi no-3/8-intshi, futhi osayizi abakhulu basinda.
Isando esijikelezayo sisebenzisa i-SDS chuck.I-groove shank yalezi zixhobo zokuzivivinya ingakhiywa endaweni yayo.I-SDS iwukuqamba okusha eJalimane, okusho ukuthi “Steck, Dreh, Sitz” noma “Faka, Twist, Stay”.Lezi zingcezu zokubhoboza zihlukile ngoba isando sikagesi sinikeza inani elikhulu lamandla, ngakho-ke indlela ephephile iyadingeka ukuze kuvikelwe i-drill bit.
Izinhlobo zebhethri eziyinhloko eziza nanoma yiliphi ithuluzi lamandla angenazintambo i-nickel cadmium (NiCd) ne-lithium ion (Li-ion).Amabhethri e-lithium-ion athatha indawo yamabhethri e-nickel-cadmium ngenxa yokuthi asebenza kahle kakhulu futhi anempilo ende yesevisi phakathi nokusetshenziswa kanye nempilo yawo yonke yesevisi.Futhi alula kakhulu, okungase kube yimbangela yokuthi usuvele uhudula i-drill yesando esindayo.
Impilo yebhethri ngesikhathi sokusetshenziswa ivamise ukukalwa ngamahora we-ampere noma u-Ah.Kuma-rigs okumba alula, amabhethri angu-2.0Ah angaphezulu kokwanele.Kodwa-ke, uma ushaya kakhulu i-masonry, ungase ufune ukuthi ibhethri lihlale isikhathi eside.Kulesi simo, bheka ibhethri elilinganiselwe ku-3.0Ah noma ngaphezulu.
Uma kudingeka, ibhethri elinesilinganiso esiphezulu sehora le-ampere lingathengwa ngokuhlukana.Abanye abakhiqizi bathengisa amabhethri afika ku-12Ah.
Uma uthenga i-drill engcono kakhulu engenazintambo ehlangabezana nezidingo zakho, cabanga ukuyisebenzisela iphrojekthi.Le phrojekthi izosebenzisana kakhulu nosayizi nesisindo sokubhola kwesando okudingayo.
Isibonelo, ukubhoboza izimbobo kuthayela odongeni lwe-ceramic akudingi i-torque eningi, isivinini noma i-BPM.I-lightweight, i-compact, i-hammer bit enesisindo esingamakhilogremu angu-2 (ngaphandle kwebhethri), ingaxazulula inkinga.Ngakolunye uhlangothi, ukubhoboza izimbobo ezinkulu kumahange esakhiwo kukhonkolo kuzodinga izimbobo ezinkulu nezisindayo zesando, mhlawumbe izando zikagesi, ezinesisindo esingafika kumakhilogremu angu-8 ngaphandle kwamabhethri.
Kuzinhlelo zokusebenza eziningi ze-DIY, i-medium hammer drill iyisinqumo esihle ngoba ingakwazi ukuphatha amaphrojekthi amaningi.Nakuba sicela ukhumbule ukuthi izoba nzima kakhulu kune-rig evamile (imvamisa isisindo esiphindwe kabili), ngakho-ke ingase ingabi yinhle ngoba iyona kuphela i-rig ku-workshop yakho.
Ngolwazi lwangasemuva lokubhobolwa kwesando kagesi okungenazintambo, uhlu olulandelayo lwemikhiqizo lokumba izimbobo ezintweni eziqinile lungakusiza uthole ithuluzi elilungile lephrojekthi yakho.

Ngamafuphi, umshini wokubhoboza isando olula usadinga ukuyisa kancane ekhaya, futhi i-Makita XPH03Z ingakwazi ukwenza umsebenzi wenziwe.Le modeli ine-1/2 inch, 3-jaw chuck, amalambu e-LED akabili, futhi inejubane elanele ne-BPM.I-drill bit inesivinini sokukhiqiza esingafika ku-2,000 RPM kanye nesivinini se-BPM esingafika ku-30,000, okukuvumela ukuthi uphathe ngempumelelo imisebenzi elula, efana nokubhoboza ngokuphumelelayo kumathayela odongeni nemigqa yokugxumeka.Uma sikhuluma ngetorque, le Makita ingakhiqiza amaphawundi angama-intshi angu-750 (cishe amakhilogremu angama-62) wesisindo.
Ngisho noma lokhu kuwumshini wokubhoboza isando olula, kusenesibambo esiseceleni sokuthuthukisa ukubamba nokulawula;futhi inomkhawulo wokujula wokuyivimbela ekugxumeni endaweni yokusebenza lapho i-drill yakho yenza i-drill iwele endaweni yokubhoboza..Lokhu okokuthenga amathuluzi kuphela, kodwa ungathenga amaphekhi angu-2 wamabhethri e-Makita 3.0Ah ngokuhlukana (atholakala lapha).Ngalawa mabhethri, le bitana ye-Makita engasindi inesisindo esingamaphawundi angu-5.1 kuphela.
Lapho uklama i-Bare-Tool 1/3-inch drill/umshayeli wesando, u-Bosch kufanele akhumbule “iphakheji elikhulu lezinto ezincane”.Le drill yesando engu-12V ene-chuck yokuzikhiya engu-3/8-intshi incane ngokwanele ukuthi ingavikelwa ebhandeni lamathuluzi (ithuluzi elingenalutho linesisindo esingaphansi kwamaphawundi angu-2), kodwa liqine ngokwanele ukuze lingene kukhonkolo namathayela.Inejubane eliphezulu elingu-1,300 RPM, ingakwazi ukukhiqiza amaphawundi angu-265 inch wetorque, futhi inezilungiselelo ze-clutch ezilungisekayo ezingu-20, okwenza lo mshayeli we-drill ongasindi asebenze ngezindlela ezihlukahlukene.Ngemva kokushintshela kumodi yesando, ingakwazi ukukhiqiza u-19,500 BPM, okukuvumela ukuthi ubhoboze amathayela, ukhonkolo nezitini ngamathuluzi alula.
Lokhu ukuthenga kwamathuluzi kuphela futhi kuhle uma usuvele ungumnikazi wenombolo encane yamabhethri e-Bosch 12V.Nokho, ungakwazi ukuthenga ibhethri engu-6.0Ah ngokuhlukana (iyatholakala lapha).
Ngokwesiko, izando zikagesi zinkulu futhi ziyasinda, okuzenza zibe umthwalo ebhokisini lakho lamathuluzi futhi zibe nzima, kodwa akunjalo ngesando esijikelezayo se-DEWALT DCH273B.Lesi sando esinzima sikagesi sinokubamba kwesibhamu okujwayelekile, ngakho sihlangene njengemishini eminingi enosayizi ophakathi.Ayinayo ibhethri futhi inesisindo esingamakhilogremu angu-5.4 kuphela, okulula.Kodwa-ke, ama-brushless motors asengakwazi ukunikeza isivinini esifika ku-4,600 BPM kanye nesivinini esiphezulu esingu-1,100 RPM.
Yize isivinini kanye ne-BPM kungewona amanani aphakeme kakhulu emakethe, lesi sando sikagesi sikhiqiza ama-joules angu-2.1 wamandla, sibhoboza i-drill yakho noma i-chisel endaweni ye-masonry ngokujulile njengemodeli enkulu.I-DEWALT DCH273B ine-SDS chuck, i-brushless motor, isibambo esiseceleni kanye nomkhawulo wokujula.Uma usuvele unamabhethri amaningana angu-20V MAX DEWALT ohlwini lwakho, ungathenga ama-hammer drill ngaphandle kwamabhethri, kodwa futhi ungawathenga ngamabhethri angu-3.0Ah.
Uma ungakaze usebenzise umshini wokubhoboza isando kagesi ngaphambilini, ungase ube nemibuzo mayelana nokubhola kukagesi nokuthi kusebenza kanjani.Ngezansi uzothola eminye yemibuzo ejwayelekile nezimpendulo zayo ukukusiza ukuthi ukhombe indlela efanele.
Ungasebenzisa isando sikagesi njengeshizolo, kodwa awukwazi ukusebenzisa i-drill kagesi.Isando esijikelezayo sinemodi engaphendukisi ibhithi uma sishaya, ngakho sifaneleka kakhulu ukushishizwa.
Yebo, nakuba zonke izimbobo zesando zisebenza njengezishayeli ze-drill bit kumaphrojekthi amaningi endlini, zingase zibe zinkulu kakhulu.
