6 Inch Hydraulic Pdc Drag Bit Drilling Carbon Steel With Long Bit Life
PDC drill bit is mainly used for drilling soft-medium formation, such as mud stone, limestone, shale, sandstone and granite etc. pdc drill bit used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water, road construction, bridge and building . pdc drill bit work under low drilling pressure, medium-low drive speed ,big drainage.
Long bit life: diamond compact cutter as the main cutting teeth, its service life is more than 10 times that of carbide, 4 ~ 5 times that of ordinary diamond bit;
High drilling efficiency: a large quantity of diamond exposing almost all (composite polycrystalline layer exposed), bit can remain sharp, thus greatly improve the penetration rate;
Low pressure and low speed drilling: bit by scratching, shear broken rock, the weight on bit only with diameter diamond impregnated bit drilling pressure by 1/3;
Good effect of gauge: our compact bit can be set with polycrystalline diamond gauge inside and outside, with high resistance to wear, gauge performance is good, can make more efficient use of cutting teeth;
Wide range of use: the practice proves that the bit is suitable for carbonate rock, limestone, chalk and clay rock, siltstone, sandstone, such as soft, medium hard (hereinafter of rock drill ability grade 9) formation drilling, compared with the average bit, 6-8 level of rock drilling, in particular, is especially significant effect;
Because of fast drilling rate and long service life, thus, fewer drilling, drilling cost is reduced greatly, has the cost performance.
PDC drill bit apply for rock formation
Medium hard (Rock, sandstone, limestone)
Very hard(Marble, flint,granite)
PDC concave drill bit
Concave three wings
Concave four wings
Specifications and models of non core diamond PDC bits:
Concave three-wings PDC drill bit is a drag type comprehensive drilling bit,mainly used in coal mine,water conservancy and hydropower,buliding construction and other industries.
