Product Description

PDC concave bit
 
Our matric body coal mine drill bit PDC drill bit for sandstone, which used to penetrating the degassing hole, drain hole, and grouting hole of coal mine. It has two types, one is steel body, and the other is matrix body. Matrix body is suitable for hard rock and the bits life span is two times than the steel body. Applicable rock formation: f<*0.  
Characteristics:
 
1.        Using PDC as the main cutting components;
2.        With the excellent wear ability and impact toughness of the PDC;
3.        High drilling speed;
4.        Improving the drilling efficiency and reduced labor intensity;
5.        The drilling efficiency of pillar model is slightly lower than concave bits, but the abrasion performance is stronger;
6.        For blade model, compared with the others, this one has a higher abrade ability and widely application;
7.        Widely used in various of different fields, mining, hydrology, subterranean, piling, water well drill and oil well drilling. It has high efficiency and strong wear resistance for drilling. 
8.        Applicable rock formation: f≤*0.
 Specification:
