Kugula zida zobowola kumakupulumutsirani ndalama ndipo-popeza nthawi zonse zimabwera mumtundu wina wa bokosi-zimakupatsani kusungirako kosavuta ndi kuzindikiritsa.
Taphatikiza chitsogozo chosavuta posankha chobowola chokhala ndi malingaliro ena. Chosankha chathu chachikulu, IRWIN's 29-Piece Cobalt Steel Drill Bit Set, imatha kugwira ntchito iliyonse yoboola - makamaka zitsulo zolimba, pomwe zobowola zokhazikika zimatha kulephera. .
Ntchito yobowola ndiyosavuta, ndipo ngakhale mapangidwe a groove sanasinthe kwa zaka mazana ambiri, mawonekedwe ake amatha kusiyanasiyana kuti akhale ogwira mtima pazinthu zosiyanasiyana.
Mitundu yodziwika kwambiri ndi zobowola zopindika kapena zobowola movutikira, zomwe ndi njira yabwino yozungulira.Kusintha pang'ono ndi kubowola nsonga ya brad, yomwe idapangidwa kuti igwiritsidwe ntchito ndi matabwa ndipo ili ndi nsonga yopapatiza, yakuthwa yomwe imalepheretsa kubowola kusuntha ( Zomwe zimatchedwanso kuyenda). Zidutswa za zomangamanga zimatsata njira yofanana ndi yokhotakhota, koma zimakhala ndi nsonga yotakata, yosalala kuti zithetse mphamvu zomwe zimakhudzidwa.
Kubowola komweko kunakhala kolemera kwambiri komanso kokulirapo. Chotsatira ndicho kubowola zokumbira, chomwe chimakhala chophwanyika ndi spikes mbali zonse ziwiri ndi nsonga ya brad pakati.Forstner ndi serrated bits. amagwiritsidwanso ntchito (amapanga mabowo oyeretsera kuposa timitengo, koma amawononga ndalama zambiri), lalikulu kwambiri limatchedwa macheka a dzenje. M'malo mobowola dzenje mwachizolowezi, izi zimadula zozungulira. Zazikuluzikulu zimatha kudula mabowo mainchesi angapo. m'mimba mwake mu konkriti kapena midadada ya cinder.
Mabowo ambiri amapangidwa ndi chitsulo chothamanga kwambiri (HSS) .Ndi yotsika mtengo, yosavuta kupanga m'mphepete mwa nthiti zakuthwa, ndipo imakhala yolimba kwambiri. Ikhoza kusinthidwa m'njira ziwiri: posintha kapangidwe kachitsulo kapena kuyika ndi zipangizo zina. .Cobalt ndi chrome vanadium zitsulo ndi zitsanzo zakale.Zitha kukhala zolimba kwambiri komanso zosavala, koma ndizokwera mtengo kwambiri.
Zovala zimakhala zotsika mtengo kwambiri chifukwa zimakhala zoonda kwambiri pa thupi la HSS.Tungsten carbide ndi black oxide ndizodziwika bwino, monga titaniyamu ndi titaniyamu nitride.Zovala za diamondi zobowola magalasi, ceramic ndi mabala akuluakulu a miyala.
Magawo oyambira khumi ndi awiri kapena kupitilira apo a HSS azikhala okhazikika pazida zilizonse zapakhomo. Mukathyola imodzi, kapena ngati muli ndi zosowa zapadera kuposa momwe mungakwaniritsire, mutha kugula chosinthira china. chachikulu.
Kupitirira apo, ndi mwambi wakale wonena za kukhala ndi zida zoyenera pa ntchitoyo.Kuyesa kuchita masewera olimbitsa thupi molakwika kuti ugwire ntchitoyo kumakhumudwitsa ndipo kungawononge zomwe mukuchita.Sizokwera mtengo, choncho nthawi zonse ndi bwino kuyika ndalama pa ntchitoyo. mtundu woyenera.
Mutha kugula zobowola zotsika mtengo ndi ndalama zochepa, ndipo nthawi zina muzichita nokha, ngakhale nthawi zambiri zimakhala zopepuka mwachangu. Ma seti obowola opangira zinthu ambiri amapezeka pa $ 15 mpaka $ 35, kuphatikiza ma bits akuluakulu a SDS. Mtengo wa cobalt ndi wokwera, ndipo ma seti akulu amatha kufika $100.
A. Kwa anthu ambiri, mwina ayi. Nthawi zambiri, amaikidwa pa madigiri 118, omwe ndi abwino kwa matabwa, zipangizo zambiri, ndi zitsulo zofewa monga mkuwa kapena aluminiyamu. , ngodya ya digirii 135 ndiyofunika.
A. Ndizovuta pang'ono kugwiritsa ntchito pamanja, koma pali mitundu yosiyanasiyana ya makina opukusira kapena zobowola zosiyana zomwe zilipo. Zobowola za Carbide ndi titanium nitride (TiN) zimafuna chomangira cha diamondi.
Zomwe timakonda: Kusankhidwa kwakukulu kwa kukula kofanana mu kaseti yabwino yokoka.Kutentha ndi kuvala cobalt yosagwira ntchito kwa moyo wautali wautumiki.Madigiri 135 amapereka zitsulo zodula bwino.Nsapato ya Rubber imateteza mlanduwo.
Zomwe timakonda: Phindu lalikulu, malinga ngati mukumvetsetsa zofooka za bits za HSS.Amapereka zobowola ndi madalaivala a ntchito zambiri zapakhomo, garaja ndi munda.
Zomwe timakonda: Pali mabowo asanu okha, koma amapereka kukula kwa dzenje 50. Titaniyamu yokutira kuti ikhale yokhazikika.Kudzipangira nokha, kulondola kwambiri.Flats pa shank imalepheretsa chuck kuti asatengeke.
Bob Beacham ndi mlembi wa BestReviews.BestReviews ndi kampani yowunikira zinthu yomwe ili ndi cholinga: kukuthandizani kuti muchepetse zisankho zanu zogula ndikukupulumutsirani nthawi ndi ndalama.BestReviews savomereza zinthu zaulere kuchokera kwa opanga ndipo amagwiritsa ntchito ndalama zake kugula chilichonse chomwe amawunika.
BestReviews amathera maola masauzande ambiri akufufuza, kusanthula ndi kuyesa zinthu kuti apangire zosankha zabwino kwambiri kwa ogula ambiri.BestReviews ndi othandizana nawo nyuzipepala angalandire ntchito ngati mutagula malonda kudzera mu umodzi mwa maulalo athu.
