Kutenga seti yezvibodzwa zvinokubatsira kuchengetedza mari uye—sezvo zvichigara zviri mubhokisi—zvinoita kuti uchengetedzeke uye uzive zviri nyore. Zvisinei, kusiyana kudiki muchimiro nezvinhu zvinogona kukanganisa zvikuru mutengo nekushanda.
Tagadzira gwara riri nyore rekusarudza seti yedhiringi ine mamwe mazano. Sarudzo yedu yepamusoro, IRWIN's 29-Piece Cobalt Steel Drill Bit Set, inogona kubata chero basa rekudhiringidza - kunyanya simbi dzakaoma, apo zvidimbu zvekudhiringi zvakajairwa zvingakundikana.
Basa rekuboorera rakareruka, uye kunyange hazvo dhizaini yemugero wekutanga isina kuchinja kwemazana emakore, chimiro chemuromo chinogona kusiyana kuti chishande muzvinhu zvakasiyana.
Mhando dzinonyanya kuzivikanwa idzo dzinoita zvekumonera kana kuti mabhora akaomarara, ayo ari sarudzo yakanaka. Musiyano mudiki ibrad tip drill, iyo yakagadzirirwa kushandiswa nematanda uye ine muromo mutete, wakapinza unodzivirira kuti bhora risafambe (unozivikanwawo sekufamba). Zvidimbu zvemasonry zvinotevera maitiro akafanana neaya ekumonera, asi zvine muromo wakafara, wakatsetseka wekubata masimba makuru anobatanidzwa.
Kana yadarika inchi imwe chete mudhayamita, madhiri ekumonera anova asingashande. Chibooreso chacho chinova chakanyanya kurema uye chakakura. Danho rinotevera idhiri rekumonera, iro rakati sandara rine spikes kumativi ese uye nzvimbo yebrad pakati. Forstner nemaserrated bits anoshandiswawo (anoburitsa maburi akachena kupfuura maspade bits, asi anodhura zvakanyanya), makuru acho anonzi mahole saws. Panzvimbo pekuboora gomba nenzira yakajairika, aya anocheka denderedzwa rezvinhu. Chibooreso chikuru chinogona kucheka maburi masendimita akati wandei mudhayamita mukongiri kana mabhuroko esimbi.
Zvidimbu zvakawanda zvinogadzirwa nesimbi inokurumidza (HSS). Hazvidhuri, zviri nyore kugadzira mipendero yakapinza, uye zvinogara kwenguva refu. Zvinogona kuvandudzwa nenzira mbiri: nekuchinja maumbirwo esimbi kana kuiputira nezvimwe zvinhu. Cobalt ne chrome vanadium steels mienzaniso yesimbi dzekare. Dzinogona kuva dzakasimba uye dzisingapfeki, asi dzinodhura zvikuru.
Mapendi ekugadzira anodhura zvishoma nekuti ane matete akatetepa pamuviri weHSS. Tungsten carbide neblack oxide zvakakurumbira, pamwe chete netitanium netitanium nitride. Mapendi ekugadzira akaputirwa nedhaimani egirazi, ceramic uye masonry bits makuru.
Seti yezvidimbu gumi nezviviri zveHSS inofanira kunge yakafanana mune chero kit yepamba. Kana ukatyora imwe, kana kana uine zvaunoda kupfuura zvainogona, unogona kutenga imwe yakasiyana. Seti diki yezvidimbu zvemasonry ndeimwe nzira huru yekuzvigadzirira.
Kupfuura izvozvo, inyaya yekare yekuti une zvishandiso zvakakodzera pabasa racho. Kuedza kuita maekisesaizi asina kunaka kuti uite basa racho kunonetsa uye kunogona kukanganisa zvauri kuita. Hazvidhuri, saka zvakakodzera kushandisa mari mumhando chaiyo.
Unogona kutenga seti yemabhora akachipa nemari shoma, uye dzimwe nguva unozviitira wega, kunyange zvazvo kazhinji kacho zvichikurumidza kuomera. Hatikurudzire mabhora emhando yepamusoro-soro—kazhinji, haabatsiri zvachose. Mhando dzakasiyana-siyana dzemabhora emhando yepamusoro anowanikwa pamadhora gumi nemashanu kusvika makumi matatu nemashanu, kusanganisira mabhora makuru eSDS. Mutengo wecobalt wakakwira, uye mabhora makuru anogona kusvika pamadhora zana.
A. Kune vanhu vazhinji, pamwe kwete. Kazhinji, dzinoiswa pamadhigirii 118, izvo zvakanaka pamatanda, zvinhu zvakawanda zvinosanganiswa, uye simbi dzakapfava senge brass kana aruminiyamu. Kana uchichera zvinhu zvakaoma zvakanyanya senge cast iron kana stainless steel, kona ye135 degrees inokurudzirwa.
A. Zvinonetsa kushandisa nemaoko, asi kune mhando dzakasiyana dzezvishandiso zvekugaya kana zvekugera zvakasiyana zviripo. Madhiri eCarbide uye madhiri etitanium nitride (TiN) anoda dhiri redhaimani.
Zvatinoda: Sarudzo yakakura yehukuru hwakajairika mukaseti inotakurika. Pisa uye bvisa cobalt kuti igare kwenguva refu. Angle ye135-degree inopa kucheka kwesimbi kwakanaka. Bhutsu yerabha inodzivirira bhokisi.
Zvatinoda: Kukosha kukuru, chero bedzi uchinzwisisa zvipingamupinyi zveHSS bits. Inopa madhiraivha uye madhiraivha emabasa akawanda mumba, mugaraji nemubindu.
Zvatinoda: Kune zvidhinha zvishanu chete, asi zvinopa maburi makumi mashanu. Kuvhara kwetitanium kuti igare kwenguva refu. Dhizaini inozviisa pakati, kunyatsoita zvinhu nemazvo. Zvidhinha zvakati sandara pahunde zvinodzivirira chuck kuti isatsvedze.
