Sharaxaada Alaabta:
Xirmooyinka batoonka dunta ee Jcdrill waxaa lagu sameeyaa birta birta ah ee tayada sare leh iyo carbides tungsten.Iyada oo loo marayo daaweynta kulaylka, qalabkayaga qodista waa ku filan yihiin inay daboolaan baahida qodista dhagaxyada waxayna leeyihiin khasaaraha ugu yar ee tamarta marka la qodayo dhagaxyada.Ka sokow, waxaan u qaabayn karnaa qashin-qubka badhanka dunta ee habaysan iyadoo loo eegayo codsiga qodista kala duwan, iyo qashin-qubka caadadu waa kuwo lagu dabaqi karo dhagax jilicsan, dhagax dhexdhexaad ah iyo dhagax adag.
Dhagaxa Drill Thread Button Bits wuxuu ku habboon yahay R22, R25, R28, R32, R35, R38, T38, T45, T51, ST58, T60Waxay leedahay dun badan.Waxa si weyn loogu isticmaalaa dhagaxa adag (f=8 ~ 18) isticmaalka qodista
