Iyo DTH bit ndicho chishandiso chekucheka dombo.Sinodrills DTH bit yakagadzirwa neyemhando yepamusoro alloy simbi inogadzirwa naTimken muUS Kunze kwezvo, zvese zvedu zveDTH zvishoma zviri kushandisa brand "Element Six" TC carbide inopa (mabhatani eTC) eBoart Longyear.Pamusoro pekugadzira tekinoroji inoita kuti DTH yedu diki ive nepamusoro uye yakavimbika mhando.
Yakasiyana dhizaini yechiso inoita kuti DTH bhiti ikwane kune akasiyana dombo mamiriro.
Flat face: Iyi dhizaini yepasirese, kunyanya kune yakaoma uye inoshungurudza dombo.Saka kazhinji, chiso chakafuratira chine hemi-spherical mabhatani dhizaini ndiyo inonyanya kufarirwa sarudzo.
Convex face: Yemhando yepamusoro dhizaini yekupfava kune yepakati yakaoma dombo kuumbwa iyo isinganyanye kushungurudza.Iyi dhizaini ine mwero wakanakisa wekupinda asi urombo mukutsauka kwegomba kana matombo akaomarara.
Concave face: Maumbirwo ematombo akaomarara ari pakati nepakati uye asinganyanyi kukwenya uye akatsemuka.Kunyanya kuchera gomba rakadzika, kutonga kwakanakisa pamusoro pekutsauka kwegomba.
