Umbhobho wesicoci soxinzelelo oluphezulu wenziwe ngezinto eziqinisa ubulukhuni, ngokubanzi i-HSS, i-ceramic okanye i-ruby. Ngenxa yokuba impompo yamanzi inokuvelisa uxinzelelo oluphezulu kakhulu, umlomo uya kuba lula kakhulu ukunxitywa, kwaye nje ukuba umlomo usemde, umlomo uya kujongana nezinto ezilahlwayo. Ke thina Injongo yokusebenzisa izinto ezomeleleyo kukunciphisa ukubola kwemilomo kwaye siqinisekise ngokuqina kombhobho omkhulu.

Izinto ezingundoqo zalo mbhobho ngokubanzi zenziwe ngentsimbi engenasici engama-420. Emva kokucima ubushushu obuphezulu, ukucinywa komhlaba kunye nezinye iinkqubo, isiseko semilomo sinokufikelela kwi-H55HRC, ephucula kakhulu ukuxhathisa kwezinto.
