Ku bijyanye no gucukura porogaramu, akamaro k'ubuziranenge no kuramba ntibishobora kuvugwa. Aha niho DTH (Down-The-Hole) imyitozo ikinirwa, itanga imikorere igezweho mubikorwa bitandukanye. Mu bakinnyi bakomeye muri uru rwego harimo Sunward, isosiyete izobereye mu gukora ibikoresho byo mu rwego rwo hejuru DTH drill bits yagenewe gukora neza, kuramba, n’umutekano. Reka dusuzume umurongo utangaje wa Sunward wibikoresho bya DTH hanyuma dusobanukirwe nimpamvu bahitamo kubanyamwuga.
Sunward yigaragaje nk'izina ryubahwa mu nganda zikoreshwa mu gucukura, yibanda ku gukora ibice nyabyo byujuje ubuziranenge bw'inganda. Kwiyemeza kuranga ubuziranenge byemeza ko ibicuruzwa byayo byose, harimo na DTH drill bits, byubatswe kugirango bihangane nibisabwa mugihe bitanga ibisubizo bihamye. Igeragezwa rikomeye nigikorwa cyo gukora kuri Sunward byemeza ko buri myitozo itanga uburambe bunoze bwo gucukura, amaherezo byongera umusaruro kubasezeranye nabakoresha.
Mubicuruzwa bigaragara muri kataloge ya Sunward harimo SWDE200B yo kugurisha, ikaba ifite ibikorwa bitangaje mubidukikije bitandukanye. Hamwe nigishushanyo cyacyo gikomeye kandi kiranga iterambere, iyi DTH drill bit ikwiranye neza nimishinga isaba igipimo cyinshi cyo kwinjira no kuramba bidasanzwe. Yaba ubucukuzi, ubwubatsi, cyangwa ubushakashatsi bwa geologiya, SWDE200B irashobora gukemura ibibazo bitoroshye byoroshye, bigatuma ihitamo ryizewe kubanyamwuga.
Ikindi kintu gitangaje cyiyongera kumurongo wa Sunward ni SWDE165Q yo kugurisha, yagenewe cyane cyane imashini nini nini nini. Iyi DTH drill bit ihuza imikorere nimbaraga, itanga imikorere idahwitse ndetse no mubutare bukomeye. Abakoresha barashobora kwizera SWDE165Q kugirango batange ibisubizo nyabyo mugihe bagabanya kwambara no kurira, bivuze kugabanya igihe cyo kugabanuka no kuzigama amafaranga mugihe kirekire.
Sunward itanga kandi byinshi SWDH102S, izwiho guhinduka no guhuza n'imiterere. Iyi myitozo ya DTH yakozwe kugirango ikore neza muburyo butandukanye bwubutaka hamwe nubutare. Igishushanyo cyacyo cyihariye cyorohereza gucukura neza hamwe no kunyeganyega gake, kuzamura ibikorwa byogukora neza no gukora neza. Muguhitamo SWDH102S, abayikoresha barashobora kungukirwa no kwizerwa no kuramba, bigatuma igikoresho cyingenzi kubakozi bose bakora.
Moderi ya SWDB200B hamwe na SWDB200 nibindi bintu byingenzi byerekanwe kumurongo wa DTH imyitozo ya Sunward. Ibice byombi byashizweho kugirango bitange imikorere myiza no kuramba, bifasha abakoresha kugera ku ntego zabo z'umushinga byoroshye. Hamwe nibintu bidasanzwe byongera umuvuduko wo gucukura no gukora neza, ibyo bits byateganijwe kugirango bikemure ibyifuzo bya kijyambere bigezweho.
Hanyuma, SWDF200 yo kugurisha iragaragara kubwubatsi bwizewe no gukora neza. Iyi myitozo ya DTH itunganijwe neza mubikorwa bitandukanye, byemeza ko abakoresha bashobora gukemura ibibazo byose byo gucukura bahuye nabyo. SWDF200 ya Sunward yakozwe kugirango itange ibisubizo byiza mubidukikije bisabwa, byerekana ubushake bwikigo cyo kuba indashyikirwa.
Mu gusoza, Sunward yihagararaho nk'umuyobozi mu isoko rya DTH imyitozo. Mugutanga ibicuruzwa bitandukanye, harimo SWDE200B, SWDE165Q, SWDH102S, SWDB200B, SWDB200, na SWDF200, isosiyete ikora ibyifuzo byinganda zitandukanye. Gushora imari muri DTH imyitozo ya Sunward bivuze guhitamo ubuziranenge, kuramba, no gukora, kwemeza ko ibikorwa byawe byo gucukura bikora neza kandi neza. Hamwe n’ubwitange bukomeye bwo guhanga udushya no kuba indashyikirwa, Sunward ikomeje gutanga ibisubizo byimbitse byo gucukura kubasezerana nabakora ku isi.
