Owona mbhobho umbhobho ulungileyo wokugqibela kufuneka wenziwe ngezinto ezizodwa ezinganyangekiyo. Ngokubanzi, sisebenzisa i-HSS, i-ceramic, i-ruby okanye i-tungsten yentsimbi. Imilomo yezi zinto ibonakaliswa ngobulukhuni obuphezulu kakhulu kunye nokumelana nokunxiba okuphezulu. Umbhobho akukho lula ukunxitywa xa usebenza kwindawo enoxinzelelo ixesha elide.

Ngokubanzi, iithumbu azilungelanga iimeko zoxinzelelo oluphezulu. Ngenxa yeempawu zamathumbu, ukuhlala kwawo kwindawo zoxinzelelo oluphezulu kakhulu kunoko kunemibhobho elukhuni, kwaye iindleko zeethumbu ezinentsebenzo efanayo ziphezulu kunaleyo yemibhobho elukhuni. Impompo akufuneki ihanjiswe, ke sicebisa ukuba usebenzise ithumbu ezimbalwa kangangoko. Ngolwazi oluthe kratya malunga nemilomo yoxinzelelo oluphezulu, nceda ukhululeke ukunxibelelana nathi.
