Inshingano 40 50 60 munsi yumwobo urutare buto buto igiciro

Mu gucukura DTH, bito yo gucukura urutare ni ugukomeza shank, piston ya drill piston ikubita mu buryo butaziguye.Kubera ko piston ihuye neza na bito bito, imbaraga nke ziratakara.Ibi biha DTH gucukura hafi igipimo cyo kwinjira hatitawe kuburebure.
Ibara: Icyatsi, Ubururu cyangwa Bishingiye kubisabwa abakiriya
DTH bits ihujwe ninyundo zijyanye (mugucukura umwobo wa diameter no kugena ibice).Abakiriya barashobora guhitamo DTH bits zabo muburyo butandukanye, nko guhindura tungsten karbide yinjizamo umwirondoro (spherical, ballistic, nibindi), umwirondoro wo mumaso (isura igororotse, ihanamye, convex, nibindi), hamwe no gutobora umwobo.
