Mapepa ekucheka mapepa muindasitiri yekugadzira mapepa akapinza uye anogara kwenguva refu, uye mashizha anogona kugadzirwa zvinoenderana nezvinodiwa nevashandisi. Izvo zvinyorwa zvemhando iyi yezvimedu zvinonyanya kukwirira-kumhanya kwesimbi, uye kune marudzi maviri e-high-speed simbi blades uye yakakwirira-speed simbi inlaid. Yakapinza uye yakagadzikana, mhando yekucheka ndeyechokwadi uye yakatsetseka, inokodzera marudzi ese emapepa, kunyanya kucheka akasiyana-siyana epamusoro-giramu akavharwa mapepa, mablades anosarudza mamakisi akasiyana e-high-speed simbi (W3, W4, 6542, W18Cr4V, M2, M35, M42, SKH-9, SKH-51) maererano nenzira dzakasiyana dzekucheka uye zvigadzirwa zvekucheka kugadzira, kuomarara kunogona kusvika 67 HRC.Kuwedzera, kune zvimwe zvigadzirwa zvakakosha, isu tinogadzirawo zvakakosha tungsten carbide blades kana inlaid tungsten carbide blades. Kuita uku kunoita kuti hupenyu hwechishandiso huve hwakasimba, uye hupenyu hwetungsten carbide blades chigadzirwa huchakwira kakawanda pasi pemaitiro ese.
