ʻO COP SHANK nā pihi kaomi kiʻekiʻe DTH drill bit

Pono:

1. ʻO ka lōʻihi o ka lawelawe ʻana o nā bits: ʻO nā mea hao, me ke ola lawelawe lōʻihi, ʻoi aku ka maikaʻi ma mua o nā huahana like i ka mākeke.
2. ʻO ka maikaʻi o ka hoʻoheheʻe ʻana kiʻekiʻe: ʻO nā pihi drill ke pale ʻia, i hiki ai i nā bits DTH ke hoʻomau i ka ʻoi, no laila e hoʻomaikaʻi nui ai i ka wikiwiki o ka wili.
3. Paʻa ka wikiwiki o ka wili ʻana: ʻOki ʻia nā ʻāpana drill a ʻoki ʻia e wāwahi i ka pōhaku.
4. Hana maikaʻi: ʻOi aku ka ikaika o ka lole JCDRILL bits, ka pale anawaena maikaʻi a hiki ke hoʻohana pono i nā niho ʻoki.
5. ʻO ka hoʻohana ʻana i kahi ākea ākea: Hōʻike ka hana i kūpono nā ʻāpana no ka pōhaku carbonate, ka limestone, ka paʻakai, ka pōhaku lepo, ka pōhaku lepo, ke one a me nā mea palupalu a paʻakikī ʻē aʻe (9-grade drill hiki o ka pōhaku, wili pōhaku paʻakikī), hoʻohālikelike ʻia me nā bits maʻamau, ʻoi aku ka wili ʻana i ka pōhaku papa 6-8 he koʻikoʻi ka hopena.

ʻO ka hoʻohana ʻana i ka hāmare DTH 

ʻEhā ʻano o ka hoʻolālā maka hope no nā ʻāpana DTH puʻe makani kiʻekiʻe: ʻano convex maka hope, ʻano mokulele maka hope, ʻano concave maka hope a me ke ʻano concave waena hohonu.Hoʻohana ka carbide sima i nā niho pōpō, nā niho puna a i ʻole ke ʻano hoʻohele niho i kaʻana like ʻia e nā niho pōpō a me nā niho puna.

Hoʻohana nui ʻia ka DTH drill bit i ka ʻimi geological, mine mine, conservancy wai a me hydropower, alaloa, alahaka, kūkulu etc.
