Hana ʻia kā mākou mau ʻāpana pihi tapered i ka carbide kiʻekiʻe a hana ʻia e ka ʻenehana kaomi anu, hiki ke hoʻopili ʻia me ka paipu wili tapered no nā wili wāwae ea a i ʻole nā ​​wili pōhaku paʻa lima no ka wili ʻana i nā lua gula a me nā lanahu, nā lua pōhaku kinikini a me nā granite, nā hana pōhaku, nā tunnels, ka mālama wai, a pēlā aku.
Hoʻolālā maikaʻi ʻia me ka tungsten carbide a me ke kila skirt, ke alakaʻi ikaika a me ke komo ʻana no ka hoʻonui ʻana i ka huahana, ka pololei maikaʻi loa, a me ka maikaʻi o ka maʻemaʻe o ka lua e loaʻa ai ka hana wili kiʻekiʻe loa no ka mālama ʻana i ke kumukūʻai wahie.
Hiki iā mākou ke hoʻolālā a hana i ke anawaena, ka helu o nā pihi a me nā lua flush, ke ʻano o ka pihi, a me ke kūlou e like me ka laʻana a i ʻole ke kaha kiʻi a ka mea kūʻai aku. Hana ʻia kā mākou mau ʻāpana pihi me ka tungsten carbide a me ke kila kiʻekiʻe a ua mālama ʻia i ke anu e loaʻa ai no ka ʻeli ʻana i ka pōhaku paʻakikī me ka liʻiliʻi o ka nalowale ikehu ma ka hoʻoili ʻana i ka ikehu hopena ikaika i loko o ka pōhaku. Ke hoʻohālikelike ʻia me nā ʻāpana chisel tapered a me nā ʻāpana keʻa tapered, hāʻawi nā ʻāpana pihi i ka ʻenehana kiʻekiʻe, ka manawa ʻeli lōʻihi i hoʻokahi hele ʻana, a me ka pono ʻeli kiʻekiʻe. Ma muli o ke kaula, hiki ke hoʻokaʻawale ʻia nā ʻāpana pihi tapered i nā ʻano domed a me ballistic.
ʻO nā ʻāpana pihi tapered nā ʻāpana tapered kaulana loa me kahi ākea o ke anawaena poʻo i loaʻa mai 26mm a 48mm. Ma ke kaomi wela ʻana i nā pihi carbide ma ka ʻaoʻao o ka ʻāpana, hāʻawi nā ʻāpana pihi tapered i ka hana wili maikaʻi a me ke ola lawelawe maikaʻi loa.
