I-Drill Bits: Izici ezibalulekile zomkhiqizo wekhwalithi

Amabhithi we-Drill amathuluzi adingekayo ezinhlobonhlobo zezimboni, ezakhiwe ekusebenzeni ngokhuni. Baza ezinhlobonhlobo zosayizi nezinto zokwakha, kepha kunezici ezimbalwa ezibalulekile ezichaza ikhwalithi embi kakhulu.

Okokuqala, okubonakalayo kwe-drill bit kubalulekile. I-Speed-Speed ​​Speed ​​(HSS) iyinto evame kakhulu, njengoba ihlala isikhathi eside futhi ingasetshenziselwa izinhlelo ezahlukahlukene zokumba. Amabhithi we-cobalt wensimbi kanye ne-carbide-tarped dripery adume ngokuqina kwawo kanye nokuphika kokushisa.

Okwesibili, ukwakheka kwe-drill bit kubalulekile. I-Shape ne-angle yethiphu kungathinta ijubane lokumba nokunemba. Ithiphu ebukhali, ekhomba kahle ilungele ukumba ngokusebenzisa izinto ezithambile, kuyilapho i-flat-tight ephukile ingcono ngezinto ezinzima. I-angle yesiphu futhi ingahluka, ngama-angles abukhali ahlinzeka ngejubane lokushayela ngokushesha kepha ukunemba okungaphansi.

Okwesithathu, i-shank ye-drill bit kufanele ibe strdy futhi ihambisane nethuluzi lokumba. Amanye ama-drill bits anama-hixagonal shanks, anikezela ukubamba okunamandla futhi avikele ukushelela ngesikhathi sokumba. Abanye banama-shanks ayindilinga, ajwayelekile futhi asebenza kahle ezinhlelweni zokumba eziningi.

Ekugcineni, usayizi we-drill bit ubalulekile. Kufanele ihambisane nosayizi wembobo edingekayo kuphrojekthi. I-Drill Bits iza ebangeni lamasayizi, kusuka kuma-bits amancane obucwebe benza izingcezwana ezinkulu zokwakha.

Ngaphezu kwalezi zici ezibalulekile, kunezinye izici okufanele zicatshangelwe lapho ukhetha ukumba, njengohlobo lokushayela olusetshenziswa kanye nohlobo lwezinto ezibonakalayo ezibikiwe. Amanye ama-bits drill aklanyelwe ukusetshenziswa ngezinto ezithile, njenge-masonry noma insimbi.

Sekukonke, kufanelekile ukudonsa kwekhwalithi kusuka ezintweni ezihlala isikhathi eside, kube nethiphu eyenziwe kahle bese ujaha, futhi ube ngosayizi ofanele wohlelo lokumba okuhlosiwe. Ngalezi zici engqondweni, ochwepheshe kanye nama-hobbyists ngokufanayo bangakhetha i-drill bit efanelekile ngamaphrojekthi abo futhi bazuze imiphumela engcono kakhulu.
