Mapepala odulira mapepala mumakampani opanga mapepala ndi akuthwa komanso olimba, ndipo masambawo amatha kupangidwa molingana ndi zomwe ogwiritsa ntchito amafuna. Zida zamtundu woterewu zimakhala ndi zitsulo zothamanga kwambiri, ndipo pali mitundu iwiri yazitsulo zothamanga kwambiri komanso zitsulo zothamanga kwambiri. lakuthwa ndi khola, khalidwe kudula ndi yolondola ndi yosalala, oyenera mitundu yonse ya pepala, makamaka kudula zosiyanasiyana mkulu-gramu TACHIMATA pepala, masamba kusankha makalasi osiyanasiyana a zitsulo mkulu-liwiro (W3, W4, 6542, W18Cr4V, M2, M35, M42, SKH-9, SKH-51) malinga ndi njira zosiyanasiyana zodulira ndi kudula kuti apange, kuuma kumatha kufika 67 HRC. Kuphatikiza apo, pazinthu zina zapadera, timapanganso masamba a tungsten carbide kapena masamba opangidwa ndi tungsten carbide. Izi zimapangitsa moyo wa chida kukhala cholimba, ndipo moyo wa tungsten carbide masamba mankhwala adzakhala kangapo apamwamba pansi ndondomeko wamba.
