Not PDC coring bits (PDC coring bits)

Three wing not PDC coring drill bit, diamond compact as the main cutting element, by scraping principle of shear rock broken, apply to soft - in hard formation drilling, and in overcoming incomplete stratum drilling has a better advantage. Not PDC coring bit by utilizing high abrasion resistance and high impact of PDC, has the advantages of high life, high aging, high cost performance.

Diamond compact bit coring bit not good stability, long service life, high drilling efficiency, low pressure drilling, at a moderate speed gauge effect is good, widely used and has the characteristics of superior cost-effective, can be widely used in geological exploration, coal mining, water conservancy and hydropower construction, highway, rail construction of rock drilling.

Our company can according to customer's requirements and geological conditions provide a wide range of conventional type diamond compact bit, to overcome the special strata dedicated diamond compact bit, etc.

Functional features

1, long bit life: is given priority to with diamond compact cutter, its service life is more than 10 times that of carbide, 4 ~ 5 times that of ordinary diamond bit;

2, high drilling efficiency: diamond with large amount of almost all (composite polycrystalline layer exposed), bit can remain sharp, thus greatly improve the penetration rate;

3, 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;

4, good effect of gauge: inside and outside our company compact bit can be set with polycrystalline diamond gauge, high resistance to wear, gauge performance is good, can make more efficient use of cutting teeth;

5, 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 drillability grade 9) formation drilling, compared with the average bit, 6-8 level of rock drilling, in particular, is especially significant effect;

6, because of fast drilling rate, long life, and thus fewer tripping, greatly reduce drilling cost, the superior price.

Specifications: #, 50 # 55, 60 #, # 65, # 75, # 85, # 94, # 113, # 133, # 153, # 173, # 173, # 200 models (three or more than four wings and wing wing)
