Kugula zida zobowola kumakupulumutsirani ndalama ndipo-popeza nthawi zonse zimabwera mumtundu wina wa bokosi-zimakupatsani kusungirako kosavuta ndi kuzindikiritsa.
Taphatikiza chiwongolero 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 zopota zokhotakhota kapena zobowola movutikira, zomwe ndi zabwino mozungulira ponseponse.Kusintha pang'ono ndikobowola nsonga ya brad, yomwe idapangidwa kuti igwiritsidwe ntchito ndi matabwa ndipo imakhala ndi nsonga yopapatiza, yakuthwa yomwe imalepheretsa kubowola kusuntha (komwe kumadziwikanso kuti kuyenda) .. Mitsuko yamiyala imatsata njira yofananira yokhotakhota, koma imakhala ndi mphamvu yayikulu yogwira.
Kubowola komweko kudakhala kolemera kwambiri komanso kokulirapo. Chotsatira ndi kubowola zokumbira, komwe kumakhala kophwanyidwa ndi spikes mbali zonse ziwiri ndi nsonga yapakati. Forstner ndi serrated bits amagwiritsidwanso ntchito (zimapanga mabowo oyeretsa kuposa zokumbira, koma zotsika mtengo kwambiri), zomwe zimatchedwa hole macheka kukhala zazikulu kwambiri. awa amadula bwalo la zinthu.Zazikuluzikulu zimatha kudula mabowo mainchesi angapo m'mimba mwake mu konkire kapena midadada ya cinder.
Mabowo ambiri amapangidwa ndi zitsulo zothamanga kwambiri (HSS) .Ndizotsika mtengo, zosavuta kupanga zitsulo zakuthwa, komanso zimakhala zolimba kwambiri.Zikhoza kusinthidwa m'njira ziwiri: mwa kusintha kapangidwe kazitsulo kapena kuzikuta ndi zipangizo zina.Cobalt ndi chrome vanadium zitsulo ndi zitsanzo za zakale.Zitha kukhala zolimba kwambiri komanso zosavala, koma zimakhala zodula 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.
Ma bits khumi ndi awiri kapena angapo a HSS ayenera kukhala okhazikika pazida zilizonse zapakhomo. Mukathyola imodzi, kapena ngati muli ndi zosowa zapadera kuposa momwe mungathere, mutha kugula chosinthira china.
Kupitilira apo, ndimwambi wakale wonena za kukhala ndi zida zoyenera pantchitoyo.Kuyesa kuchita masewera olimbitsa thupi molakwika kuti ugwire ntchitoyo kumakhumudwitsa ndipo kumatha kuwononga zomwe mukuchita.Sizokwera mtengo, choncho nthawi zonse ndi bwino kuyika ndalama mumtundu woyenera.
Mutha kugula zobowola zotsika mtengo zandalama zingapo, ndipo nthawi zina muzichita nokha, ngakhale kuti nthawi zambiri zimakhala zopepuka mwachangu.
A. Kwa anthu ambiri, mwina ayi. Kawirikawiri, amayikidwa pa madigiri a 118, omwe ndi abwino kwa matabwa, zinthu zambiri zophatikizika, ndi zitsulo zofewa monga mkuwa kapena aluminiyamu. Ngati mukubowola zinthu zolimba kwambiri monga chitsulo chosapanga dzimbiri kapena chitsulo chosapanga dzimbiri, ma angle a 135 degree akulimbikitsidwa.
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.
