Mhezi yeiyo yakamanikidza-kuchenesa inogadzirwa neyakaomesesa zvinhu, kazhinji HSS, ceramic kana ruby. Nekuti iyo pombi yemvura inogona kuburitsa yakanyanya kukwirira kumanikidza, iyo kamwene ichave iri nyore kupfeka, uye kana iko kamwene ikapfekwa, iyo kamwene inotarisanawo nesara. Saka isu Chinangwa chekushandisa zvakanyanya-kuomarara zvinhu kudzora kusakara kwemubhedha uye kuona kugadzikana kwemhino zvakanyanya.

Izvo zvakakosha zvinhu zveiyi mhere zvinowanzo gadzirwa ne420 simbi isina simbi. Mushure mekudziya kwepamusoro kwekudzima, pamusoro pekupfuura uye mamwe maitiro, iyo simbi yekumusoro inogona kusvika ≥55HRC, iyo inovandudza zvakanyanya kupfeka kuramba kwechinhu.
