Ubwa mbere uhindagurika, gukomera no gukomera birasa nkibishobora guhinduranya, ariko bibaho kumpande zinyuranye zumurongo usobanura kwinjiza ibintu byerekana no gukata ibikoresho bikomeye, cyane cyane kubijyanye no gushyiramo karbide. Kwinjiza gukomeye bitanga imbaraga zo kwambara kugirango zongere imikorere nubuzima bwibikoresho ahantu hashyushye kuruta uko byoroheje byinjiza, nyamara gushiramo bigoye birashobora kwihanganira ingaruka hamwe nihungabana kugirango ugere ku kigero kinini cyibiryo na DOC.

Kuri porogaramu iyo ari yo yose yatanzwe, hari uburyo bwiza bwo gukomera no gukomera - kandi abakora ibikoresho bakoze cyane bashiraho amahame ya metallurgjiya kandi batanga ibikoresho bitandukanye bishobora guhuza ibyifuzo bitandukanye byabakora ibice.

Gukomera byerekana kwihanganira kwambara, bisobanura mubushobozi bwigikoresho cyo guhangana nubushyuhe mugihe cyo gutema ibyuma. Igipimo cya Rockwell Igipimo gipima ubukana bwa karubide ya tungsten, nubwo bimwe mubisobanuro bihindura indangagaciro za HRA kubipimo bisanzwe bya HRC bikoreshwa mugupima ubukana bwibyuma nibindi bivangwa. Ubushyuhe bwo guhangana nubukomezi bugira uruhare runini mugukata ibikoresho no guhitamo.
