Hasi umwobo dth gucukura inyundo bito
1.Ubuzima burebure bwimyitozo: ibikoresho bivanze, hamwe no gukoresha ubuzima buruta ibicuruzwa bisa;
2.Ubushobozi Bwinshi bwo Kuzuza: buto ya dril irwanya kwambara, kuburyo imyitozo ishobora guhora ikarishye bityo bikazamura cyane umuvuduko wa drllng.
3.Umuvuduko wo gucukura urahagaze: biti byarakuweho kandi biracibwa kugirango umenagure urutare.
4.Imikorere myiza: Bitike ya Diamond ifite imbaraga zo kurwanya kwambara, kurinda neza Diameter kandi birashobora gutuma amenyo yo gutema akoreshwa neza.
5.Ikoreshwa ryurwego runini: imyitozo irerekana ko biti ikwiranye nubutare bwa karubone, hekeste, chalk, urutare rwibumba, amabuye ya silt, amabuye yumucanga nibindi byoroshye kandi bikomeye (gucukura ibyiciro 9 byamabuye, gucukura amabuye akomeye), ugereranije hamwe na biti bisanzwe, cyane cyane gucukura muri 6-8 urwego rwibuye ingaruka ningirakamaro cyane.
