钻具特点：
1、筒体环切释放岩石围压；
2、牙轮钻齿滚压研磨钻进，钻齿损耗小 ;
3、小钻具取芯率高，大钻具分级配合破碎 ;
4、适用地层：中、微风层岩层，硬岩层，超硬基岩层；
Features:
1.Cutting ring with rock drilling bits helps release the internal stress of rock
2.When drill in the full fracture rock layer, crossing cutter makes it easy to carry soil
3.Kelly box: 130mm,150mm,200mm(optional)
4.Barrel adopts spiral wear-resistant strips for anti-attrition to prolong the service life
5.Many alloy teeth are used for higher drilling efficiency
6.Heightened design with high construction efficiency, reducing construction cost
钻斗描述：
1.筒钻用于在岩石或混凝土或钢筋混凝土中环切。
2.岩石或混凝土的中心核心通常用岩石螺旋钻粉碎。 取芯筒最重要的优点是它有助于将扭矩和挤压力集中在一小圈切割齿上。
Descriptions:
1.Core barrels are used to cut an annular ring in rock or concrete or reinforced concrete.
2.The center core of the rock or concrete is usually crushed with rock auger. The most important advantage of a core barrel is that it assists to concentrate the torque and crowd force on a small ring of cutting teeth.
