1.The high wear resistance of cutting tooth 2.Extend bit service life 3.Bit has good guidance

 Materials of Diamond PDC Core Bit for Mining Machinery 

1, Senior tungsten carbide do tire body, a molding cutting edge, hardness, not breached, impact resistant2, Article unique alloy welding method increase drill body wear resistance3, High quality full thickness clad sheet4, Expensive silver solder paste don't brazing and prevent damage to the compound piece of life.

Main features and functions of  Diamond PDC Core Bit for Mining Machinery 

1, bit long life: to diamond compact give priority to cutting tooth, its service life is hard alloy 10 times above, is common diamond bit of 4 ~ 5 times;2, high drilling efficiency: diamond exposed big (composite polycrystalline layer almost all exposed), bit can always stay sharp, thus greatly improve the penetration rate;3, low pressure, low speed drilling: bit to scart, shear to broken rock, the drill pressure just with diameter diamond impregnated bit drill pressure 1/3;4, gauge effect is good: my company compact bit inside and outside can Mosaic diamond polycrystalline gauge, wear resistance is strong, gauge performance is good, can make the cutting teeth get efficient utilization

Use Scope of    Diamond PDC Core Bit for Mining Machinery 

Practice proves that the diamond core bit is suitable for carbonate, limestone, chalk rock, clay rock, siltstone, sandstone and soft, medium hard (drillability 9 below the rank of rock) formation of drilling, with general bit compared, especially drilling 6-8 magnitude rock formation, the effect is particularly significant.

Advantages of    Diamond PDC Core Bit for Mining Machinery 

1.Quickly drill speed , long service life

2.Greatly reduced the cost of going down with less number of drilling 

3. has superior performance-to-price ratio
