钻具特点：
筒体环切释放岩石围压；
截齿阶跃破碎兼研磨钻进 ;
小钻具取芯率高，大钻具分级配合破碎 ;
适用地层：回填层、中风化岩层，基岩层；
Features:
1.Cutting ring with staggered arrangement of round shank chisels
2.Chisel holders are welded to the base body. The round shank chisels can be easily replaced
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切割环形圈。
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.
