Impregnated Diamond Bits

Impregnated diamond drill bits are usually made of diamond, steel, cemented carbide powder and polycrystalline diamond. Impregnated diamond bit is used to drilling in the hard rock and the diamond will break rock in micro cutting way.

Features

1. Impregnated diamond drill bits feature simple structure, high strength, high wear resistance and high impact ability.
2. Impregnated diamond bit is suitable for small borehole, which not restricted by borehole size.
3. In soft medium hard formation, it has advantage of high drilling speed, lots of cumulative process, long service life, stable work, good pore forming quality and adaptable ability to high speed (400 RPM).
