Ukuthenga isethi ye-drills kukugcina imali kwaye-ekubeni behlala beza kuhlobo oluthile lwebhokisi-kukunika ukugcinwa okulula kunye nokuchonga.Nangona kunjalo, ukungafani okubonakalayo okuncinci kwimilo kunye nezinto eziphathekayo kunokuba nefuthe elikhulu kwixabiso kunye nokusebenza.
Sidibanise isikhokelo esilula ekukhetheni isuntswana lokubhola kunye neengcebiso ezithile.Olona khetho lwethu luphezulu, i-IRWIN's 29-Piece Cobalt Steel Drill Bit Set, inokusingatha malunga nawo nawuphi na umsebenzi wokomba - ngakumbi iintsimbi ezinzima, apho amasuntswana edrill asemgangathweni angasilela. .
Umsebenzi we-drill ulula, kwaye ngelixa uyilo olusisiseko lwe-groove aluzange lutshintshe amakhulu eminyaka, i-tip shape inokwahluka ukuze isebenze kwizinto ezahlukeneyo.
Ezona ntlobo zixhaphakileyo zi-twist drills okanye i-rough drills, eziyindlela elungileyo yonke indawo.Ukwahluka okuncinci yi-brad tip drill, eyenzelwe ukusetyenziswa ngamaplanga kwaye inencam emxinwa, ebukhali ethintela i-drill ekuhambeni ( okwakwaziwa njengokuhamba).Amasuntswana okwakha alandela ipateni efanayo ukujija iidrili, kodwa abe nencam ebanzi, ethe tyaba yokuphatha amandla empembelelo ephezulu ebandakanyekayo.
Kanye ngaphezu kwe-intshi ububanzi, ukujijwa drills kuba engenakwenzeka.I-drill ngokwayo yaba nzima kakhulu kwaye bulky.Inyathelo elilandelayo yi-drill umhlakulo, nto leyo sicaba kunye izikhonkwane macala kunye nenqaku brad phakathi.Forstner kunye namasuntswana serrated zikwasetyenziswa (zivelisa imingxuma ecocekileyo kunemihlakulo, kodwa zibiza ngaphezulu), eyona inkulu ibizwa ngokuba ziisarha zomngxuma. Endaweni yokomba umngxuma ngendlela eqhelekileyo ezi zisike isangqa sezinto.Eyona inkulu inokusika imingxunya i-intshi ezininzi ububanzi kwikonkrithi okanye iibhloko zecinder.
Uninzi lwee-drill bits zenziwe ngentsimbi yesantya esiphezulu (HSS) .Akubizi, kulula ukuvelisa imiphetho yokusika ebukhali, kwaye ihlala ixesha elide.Inokuphuculwa ngeendlela ezimbini: ngokuguqula ukubunjwa kwentsimbi okanye ukuyigubungela ngezinye izinto. .I-Cobalt kunye ne-chrome vanadium steels yimizekelo yangaphambili.Zinokuba nzima kakhulu kwaye zinxibe, kodwa zibiza kakhulu.
Iingubo zokwaleka zifikeleleka ngakumbi ngenxa yokuba ziyimigangatho emincinci kumzimba we-HSS.I-tungsten carbide kunye ne-oxide emnyama zithandwa, njenge-titanium kunye ne-titanium nitride.I-diamond-coated drill bits yeglasi, i-ceramic kunye ne-masonry bits enkulu.
Iseti esisiseko yeshumi elinesibini okanye ngoko ke amasuntswana e-HSS kufuneka ibe semgangathweni kuyo nayiphi na ikhithi yasekhaya.Ukuba uyaphula, okanye ukuba uneemfuno ezithile ezingaphaya komda wayo, ungasoloko uthenga indawo eyahlukileyo. isiseko.
Ngaphaya koko, sisithethe esidala malunga nokuba nezixhobo ezifanelekileyo zomsebenzi.Ukuzama ukwenza umthambo ongafanelekanga ukwenza umsebenzi kuyakhathaza kwaye kungonakalisa into oyenzayo.Azibizi, ngoko kusoloko kufanelekile ukutyala imali kwishishini. uhlobo oluchanekileyo.
Ungathenga iiseti zoqeqesho ezinexabiso eliphantsi ngeerandi ezimbalwa, kwaye ngamanye amaxesha uzenze ngokwakho, nangona zikholisa ukuba buthuntu ngokukhawuleza.Asinakucebisa amasuntswana okwakha akumgangatho ophantsi-kaninzi, awanamsebenzi.Udidi oluphezulu lomgangatho ophezulu Iiseti ze-drill zenjongo jikelele ziyafumaneka kwi-15 yeedola ukuya kwi-35 yeedola, kubandakanya i-SDS enkulu ye-masonry bits.Ixabiso le-cobalt liphezulu, kwaye iiseti ezinkulu zinokufikelela kwi-100 yeedola.
A. Kubantu abaninzi, mhlawumbi akunjalo. Ngokuqhelekileyo, zibekwe kwii-degrees ze-118, ezilungele kakhulu iinkuni, izinto ezininzi ezidibeneyo, kunye neentsimbi ezithambileyo ezifana nobhedu okanye i-aluminium. , i-angle ye-135 degree iyacetyiswa.
A. Kubuqhinga kancinci ukusebenzisa ngesandla, kodwa kukho iindidi ngeendidi zezinto zokusila okanye iziloli ezahlukeneyo ezikhoyo.Ii-Carbide drills kunye ne-titanium nitride (TiN) drills zifuna umloli osekwe ngedayimani.
Into esiyithandayo: Uluhlu olubanzi lweesayizi eziqhelekileyo kwikhasethi yokukhupha i-cassette efanelekileyo.Ukushisa kunye nokugqoka i-cobalt enganyangekiyo kwinkonzo eyandisiweyo.I-angle ye-135-degree inikeza i-metal cutting esebenzayo.I-Rubber boot ikhusela ityala.
Esikuthandayo: Ixabiso elikhulu, nje ukuba uyayiqonda imida ye-HSS bits.Ibonelela ngeedrili kunye nabaqhubi bemisebenzi emininzi ejikeleze ikhaya, igaraji kunye negadi.
Esikuthandayo: Kukho amaqhekeza amahlanu kuphela okugaya, kodwa anikezela ubungakanani bemingxuma engama-50. I-Titanium yokwambathisa ukwenzela ukuqina.Uyilo lokuzibamba, ukuchaneka okuphezulu.Iiflethi kwi-shank zithintela i-chuck ekutyibilikeni.
