異型多棱刻槽鉆桿是一種擁有護孔、泄壓、扶正、降溫的專(zhuān)利產(chǎn)品，適用于煤礦坑道鉆探本煤層瓦斯抽放，是為松軟煤層深孔鉆探而研發(fā)的。因此，它不同于普通鉆桿。異型多棱刻槽鉆桿制造過(guò)程中使用了專(zhuān)利技術(shù)，使其物理動(dòng)力學(xué)特性不同于市場(chǎng)上的常規產(chǎn)品。當異型多棱刻槽鉆桿在市場(chǎng)上獲得較大成功時(shí)，其它品牌一些產(chǎn)品也利用了異型多棱刻槽鉆桿的原理，這些產(chǎn)品大部分外觀(guān)與異型多棱刻槽鉆桿相似，但它們都沒(méi)有觸及到異型多棱刻槽鉆桿的核心設計結構。
