Iwo anogadzirwa kuDIN 1897 indasitiri zviyero (metric saizi), iyo inobatsira kuve nechokwadi chekuti mabhiti ekudhirowa pasirese, anoenderana neakatsanangurwa mamwe.
Iwo anoshandiswa mumichina yakadai semadhiri anotakurika anobatwa nemaoko, madhiri, machining nzvimbo, uye lathes. Drill bits inouya mumhando dzakasiyana uye kureba.
Inonamatira kumazinga eNAS 907, anoshandiswa muindasitiri yezvemuchadenga zvibooreso zvenguva pfupi, kuitira kusimba uye kuwedzera simba Simbi inomhanya kwazvo (HSS) ine cobalt musanganiswa wakanaka wekuoma nekuoma, kushandiswa pakuchera kuburikidza nezvinhu zvakaoma Gold oxide. , inochengeta mvura yekucheka uye inodzivirira chip kune mudziyo welding 135-degree split point angles, yakanaka kune yakaoma, yakaoma zvinhu.
Features
Ichi chibooreso chine chaiyo yepasi mbiri, yekurudyi yekucheka mhando N uye imwe pfupi pfupi cylindrical dhizaini. Iine yakakwirira-inoshanda HSS zvinhu uye 135 ° tapered chikamu, muchinjiko-pasi wakatsetseka pamusoro pekupedzisira unowirirana neDIN 1412 C (kubva pa3.0 mm dhayamita).
Applications
Pamahwendefa matete, simbi uye simbi yakakandwa (yakasanganiswa uye isina kusanganiswa, simba rinosvika 800 N/mm²), simbi yakaumbwa, simbi inogadzika, ductile iron, short-chip aruminiyamu alloys, mhangura, hard brass, bhuronzi, die castings, zvichingodaro.
Advantage
Kunyanya akakodzera kudhibhisa anobatwa nemaoko, nekuda kweiyo self-centering drill tip, iyo inogonesa kudhirowa kwakanyatso kutungamira pasina kushandiswa kwepakati punch.
Isu tanga takatarisana nekutsvaga, kusimudzira, kugadzira uye kutengesa kweHSS twist drill bits. Isu tinopa akasiyana siyana eHSS twist drill zvigadzirwa uye zvakatemwa kuti zvisangane neakasiyana mazinga, akakosha maitiro uye munhu akasarudzika zvinodiwa. Mukati memakore 14 apfuura, takazvivakira mukurumbira wakanaka kupfurikidza nenhamburiko dzedu dzakazara. Zvigadzirwa zvedu zvinotumirwa kuRussia, USA, Germany, France, Thailand, Vietnam, Brazil, Middle East nedzimwe nyika dzakawanda nematunhu, uye isu tinopa zvigadzirwa zvedu kumabhureki pasi rese.
