Idayamitha yangaphandle yombhobho ongenamthungo oqengqelekayo ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-200mm. Ububanzi obungaphandle bombhobho wentsimbi ongenamthungo obandayo bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. Idayamitha yangaphandle yombhobho obhityileyo unokufikelela kwi-5mm kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm.

Umbhobho wentsimbi esetyenziswa ngokubanzi ingenamthungo yenziwe nge-10, 20, 30, 35, 45 kunye nezinye ezikumgangatho ophezulu we-carbon bonded steel 16Mn, 5MnV kunye nezinye intsimbi ephantsi yolwakhiwo lwentsimbi okanye i-40Cr, 30CrMnSi, 45Mn2, 40MnB kunye nezinye intsimbi edibeneyo ebandayo rolled.10, 20 kunye nezinye intsimbi ephantsi carbon umbhobho wokuvelisa ingenamthungo usetyenziswa ikakhulu kumbhobho wolwelo.45, 40Cr kunye nezinye intsimbi yekhabhoni ephakathi eyenziwe ngombhobho ongenamthungo ukuvelisa iindawo ezingoomatshini, ezinjengeemoto, iitrektara ezigxininisiweyo. Imibhobho yentsimbi eshushu ihanjiswa kwindawo eshushu eqengqelekayo okanye ephathwa ngobushushu.
