Abantu abaningi bavame ukudideka lapho becabanga ukuthi bazoyithenga yini i-drill engu-18V noma engu-20V. Kwabaningi ukukhetha kuncike kuleyo ebonakala inamandla kakhulu. Vele i-20v Max izwakala sengathi inamandla amaningi kodwa iqiniso liwukuthi i-18v inamandla afanayo. Ukubheka ukufana nokwehluka okuhlukahlukene phakathi kwale mikhiqizo kungaba yisihluthulelo sokuqonda ukuthi uthola ini uma uthenga noma yimuphi wayo.
Iqiniso ngamabhethri angu-18v vs 20v:
Uma uhlukanisa noma yiliphi lala mabhethri amabili uzobona ukuthi aklanywe ngendlela efanayo. Womabili anamaseli ebhethri ngamanye ahlelwe eqenjini lama-5 axhunywe ngochungechunge. Iqembu ngalinye lamaseli ama-5 lixhunywe ngocingo ngendlela efanayo. Lokhu kwenziwa ukuqinisekisa ukuthi ibhethri linenani elikhulu kakhulu lamahora e-amp. Kwenziwa futhi ukuqinisekisa ukuthi ibhethri linomthamo omuhle ngokwehora lama-watt.
Ukubheka ngokujulile la maseli kwembula ukuthi ngalinye linezilinganiso ezimbili ezihlukene zama-voltage okungukuthi okujwayelekile kanye nokuphezulu. Iseli ngalinye ebhethrini le-18v noma le-20v linesilinganiso se-voltage esingu-3.6 volts okuhunyushwa kube ama-volts angu-18 okujwayelekile uma lihlanganiswa. Iseli ngalinye ebhethrini le-18v noma le-20v linesilinganiso esiphezulu sama-volts angu-4 okuhunyushwa kube ama-volts angu-20 aphezulu uma lihlanganiswa. Empeleni abakhiqizi bebhethri le-18v basebenzisa isilinganiso esiphezulu kuyilapho abakhiqizi bebhethri le-20v max besebenzisa isilinganiso esiphezulu. Lona umehluko omkhulu phakathi kwale mikhiqizo emibili.
Njengoba sesiphawulile okungenhla, kusobala ukuthi womabili la mabhethri akhiqiza amandla afanayo. Umehluko kuphela usekukhangisweni noma ekubhalweni kwawo maqondana nezilinganiso zamaseli. Omunye umehluko obalulekile ukuthi amabhethri angu-20v max avamile e-United States kanti amabhethri angu-18v athengiswa ngaphandle kwe-United States. Kodwa-ke, umuntu osebenzisa amabhethri angu-18v ngaphandle kwe-US uthola imiphumela efanayo nalowo osebenzisa ibhethri elingu-20v max ngaphakathi kwezwe.
Kubalulekile futhi ukuqaphela ukuthi kukhona amathuluzi aklanyelwe ukusebenza ngamabhethri angu-18v kuyilapho kukhona neqembu lamathuluzi aklanyelwe ukusebenza ngamabhethri angu-20v max. Lokhu kungaletha enye impikiswano kubantu abaningi abakhetha ukusebenzisa ithuluzi elingu-20v max ngoba lizwakala linamandla kakhulu. Ulwazi olungezansi luzokusiza ukhethe ithuluzi elifanele maqondana nokubhola.
I-drill engu-18v vs 20v - Yikuphi okufanele ukhethe?
Njengoba kushiwo ngenhla akukho mehluko wangempela phakathi kwezinhlobo ezimbili zamabhethri. Kodwa-ke, kungaba nomehluko omkhulu uma kukhulunywa ngemishini yokusebenzisa uhlobo ngalunye lwebhethri. Ukuze wenze ukukhetha okufanele, welulekwa ukuthi ubheke imininingwane elandelayo.
Izindleko zomshini wokubhoboza–Inani lemali okhokhiswayo nge-drill esebenzisa ibhethri le-18v lingahluka ezindleko ze-drill yebhethri le-20v max. Ungathengi i-drill ngoba nje ibonisa i-20v max kunalokho qhathanisa amanani ezinhlobo ezahlukene ze-drill emakethe bese unquma leyo ebonakala inikezwa ngentengo efanelekile. I-drill ye-18v eshibhile ingakunikeza ukusebenza okuhle kakhulu kuyilapho i-drill ye-20v max ebizayo ingase ingabi yinhle njengoba ungase ucabange.
Cabanga nge-torque -Kungakhathaliseki ukuthi ubhoboza kanjani, enye yezinto ezibaluleke kakhulu okufanele uzicabangele yi-torque ephezulu oyitholayo. Uma i-drill engu-18v inikeza i-torque ephezulu kufanele uyenze. Ngakolunye uhlangothi, uma i-drill engu-20v inikeza i-torque engcono kufanele uyikhethe kuneyomncintiswano wayo. Uma i-torque ye-drill iphakeme, imiphumela engcono uzothola lapho ubhoboza ezindaweni eziqinile.
Usayizi nesisindo –Usayizi nesisindo se-drill ethile kungenye into okudingeka uyicabangele ngaphambi kokuthenga. I-drill engu-20v esindayo ingabangela ubunzima obukhulu phakathi nephrojekthi. Akukhona nje ukuthi cishe uzokhathala ukuyibamba endaweni yayo, kodwa futhi uzokhathala njengoba usuka endaweni eyodwa uye kwenye. Kunconywa ukuthi ukhethe i-drill elula engu-18v ngoba kungenzeka inikeze imiphumela engcono. Uma kukhulunywa ngosayizi konke kuncike kulokho ozokusebenzisa i-drill yakho. Labo abasebenzisa ama-drill ezindaweni ezincane kungadingeka bathenge imikhiqizo emincane. Ngakolunye uhlangothi, abantu abasebenza ezindaweni ezinkulu bangaba nenkululeko yokukhetha i-drill yanoma yiluphi usayizi uma nje ihlangabezana nokulindelwe kwabo.
Ukusetshenziswa –Into eyodwa eyenza i-drill ibe yinhle kakhulu ukuthi isebenziseka kalula. Kulesi simo i-drill enhle ileyo enezinto ezifana nezinkomba zokukhanya nezaziso zomsindo. Lezi zinto zenza kube nokwenzeka ukuthi noma ubani ayisebenzise. Izibani ezinemibala ehlukene zinganikeza ulwazi mayelana nezilungiselelo zamanje namandla atholakalayo. Kuwukuhlakanipha ngawe ukukhetha i-drill engu-18v enalezi zici kunokukhetha i-drill engu-20v max ngaphandle kwazo.
Umkhiqizo ubalulekile –Ngaphambi kokuthi uthenge noma yikuphi, zinike isikhathi sokufunda ngemikhiqizo ehlukahlukene emakethe. Dala uhlu lwemikhiqizo ethembekile kakhulu phezulu. Sebenzisa lolu hlu ukuze uhlole imikhiqizo ehlukahlukene emakethe. Imikhiqizo efanaI-MakitafuthiI-Dewaltziphakathi kwezidumile kakhulu futhi ezidumile yingakho kufanele ukhethe amathuluzi azo kungakhathaliseki ukuthi i-voltage ikhombisa ukuthini.
Izesekeli –Ukuze wenze umsebenzi ube lula kufanele ukhethe izindlela zokuziqeqesha ezingasetshenziswa kanye nezesekeli ezahlukene. Lokhu kuzokwenza ukuthi uqede amaphrojekthi akho ngesikhathi esifushane nangokunemba okukhulu.
Ngamafuphi, amabhethri angu-18v vs 20v max
Njengoba usufundile akukho mehluko wangempela phakathi kwebhethri elingu-18v nelingu-20v ngaphandle kwemibandela yokumaketha nendawo yokusebenzisa. Kungakhathaliseki ukuthi uthenga elokuqala noma elokugcina, amandla okugcina owatholayo ekupheleni kwenqubo afana. Ukubheka ngokucophelela amathuluzi onentshisekelo yokuwathenga kuyindlela engcono kakhulu yokwenza isinqumo esifanele kunokuthembela ku-voltage ekhonjisiwe.
