Product Description

Impregnated diamond bit: 

Impregnated bits can penetrate a broad range of formations from the softest to the hardest rocks. They are manufactured with very small, high quality synthetic diamonds mixed evenly through a tungsten carbide matrix. During drilling the matrix wears away evenly resulting in continuous exposure of new, sharp diamond points throughout the life of the bit.
All impregnated bits have T.C. and diamond gauge protection. The optimum diamond size, concentration and matrix composition varies according to the hardness and abrasiveness of the rock formations to be drilled.
 
Features: 

1: The impregnated diamond core bits features drilling speed and long service life 
2: The design of more cutting edges makes drilling progress smoother 
3: During the manufacturing process, the diamond is free erosion and fully utilized 
4: The impregnated diamond core drill bits are of various configurations and meet various needs of local conditions 
5: It offers the most widely-used bit matrices as well 
6: With various specifications, our series matrix range provide an easy selection and reliable foundation for your drilling needs 

Size: Our bits are available in all standard drilling sizes. Also, non-standard sized bits can be produced according to requirements from clients 

Matrix height: 6mm-8mm (most cost-effective), 8mm-10mm (long service life), 12mm-16mm (super service life) 

Bit Crown Profiles: "W" profile, "Flat" profile, "Semi-round" profile, "Cross" profile, "Gear profile" 

Waterways: Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems. 

Threads: Standard Q threads as well as thread types required by clients are available 

If you need any further information, please feel free to contact with us, we will be quite pleased to show all the details you asked for.
