Description
<span style="

One specialist maker of rock drilling tools/accessories, founded in 1958. The drill bit and drill rods are used for mining, quarrying, tunneling

steel body PDC bit for oil drilling tools

Use high-quality steel to make the base material of PDC bit,the surface of the blade weld high-performance wear-resistant materials.

General description of our PDC drill bits
