DTH hammer bits/tricone bit/PDC bits PDC buttons

Product applications:

SDB Diamond Hammer Bit Inserts Series is a proprietary product of our company. The products have replaced the traditional tungsten carbide inserts, usually applying to roller bits, air hammers and DTH (down-the-hole) bits and so on, especially in hard and complicated layer drilling.

Product Advantages:

1.We adopt the most advanced technical formula and synthetical technique from home and abroad. Using the hyperfine diamond powder as raw materials, the diamond layer can reach 2-3mm.The sintering technology that can form stable D-D combinations between the molecules has greatly improved the durability and toughness, and prolong the service life of PDCs.

2.We adopt special technique in the combination of diamond and kentanium that make the WC dissolve into the diamond under high temperature and high pressure so as to ensure the impact resistance.

3.We use a special binding material between the diamond and kentanium to eliminate the heat stress of the junction.

PDC theory

PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that’s made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one.

Specifications

We also can design PDC according to customer requirements.

Service 

Guilin Star Diamond can supply all kinds of PDC cutter. PDC cutters can be widely used in the fiel

ds of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway.
