Byakozwe kuri DIN 1897 yinganda zinganda (metric sizing), ifasha kwemeza ko imyitozo ya bits ku isi yose, ihuye nibisobanuro bimwe.
Zikoreshwa mu mashini nk'imyitozo ngororamubiri igendanwa, imashini zicukura, ibigo bitunganya imashini, ndetse n'umusarani. Imyitozo ya myitozo ije muburyo butandukanye n'uburebure.
Yubahiriza ibipimo bya NAS 907, bikoreshwa mu nganda zo mu kirere Bito birebire byimyitozo ngororamubiri, kugirango bikomere kandi byongerwe imbaraga Icyuma cyihuta cyane (HSS) kirimo cobalt ni ihuriro ryiza ryo gukomera no gukomera, kugirango ukoreshwe mu gucukura ukoresheje ibintu bikomeye Gold oxyde , igumana gukata amazi kandi ikarinda chip kubikoresho byo gusudira dogere 135 ya point point ya point point, nibyiza kubikoresho bikomeye, bikomeye
Ibiranga
Iyi myitozo ifite umwirondoro wubutaka, ubwoko bwiburyo bwo gukata N nuburyo bwiyongereye bwa silindrike. Nibikorwa byayo byinshi bya HSS hamwe na 135 ° byapimwe, igice cyambukiranya ubutaka cyoroshye gihuye na DIN 1412 C (kuva kuri 3.0 mm diameter).
Porogaramu
Kubisahani yoroheje, ibyuma nibyuma (bivanze kandi bidashimishije, imbaraga zigera kuri 800 N / mm²), icyuma gikozwe, icyuma cyoroshye, icyuma cyoroshye, icyuma kigufi cya aluminiyumu, umuringa, umuringa ukomeye, umuringa, gupfa, nibindi.
Ibyiza
By'umwihariko bikwiranye nintoki zifata intoki, tubikesha inama yo kwikorera wenyine, ituma gucukura neza neza bidakoreshejwe udakoresheje hagati.
Twibanze ku bushakashatsi, iterambere, umusaruro no kugurisha HSS twist drill bits. Dutanga ibyiciro bitandukanye bya HSS twist drill ibicuruzwa nibisobanuro kugirango twuzuze ibipimo bitandukanye, inzira zidasanzwe hamwe nibisabwa byihariye. Mu myaka 14 ishize, twiyubashye neza binyuze mu mbaraga zacu zidacogora. Ibicuruzwa byacu byoherezwa mu Burusiya, Amerika, Ubudage, Ubufaransa, Tayilande, Vietnam, Burezili, Uburasirazuba bwo hagati ndetse n'ibindi bihugu byinshi n'uturere, kandi dutanga ibicuruzwa byacu ku bicuruzwa ku isi hose.
