Ma batire athu odulira amapangidwa ndi chitsulo cha tungsten cholimba kwambiri ndipo adapangidwa makamaka kuti adule molondola zidutswa za batire ya lithiamu ndi zolekanitsa. Masamba awo akuthwa, osawonongeka amapanga mabala osalala, opanda ma burr, amachotsa bwino ma burr ndi fumbi, ndikuwonetsetsa kuti batire ikugwira ntchito bwino. Chodulira chodulira chingagwiritsidwe ntchito ndi chogwirira zida chofananira kuti chiyike mosavuta komanso chigwire ntchito bwino, zomwe zimapangitsa kuti chigwiritsidwe ntchito kwambiri popanga mabatire a lithiamu.
