Product Introduction:
PDC non coring drill bit is mainly used for water injection and drainage in coal mine geology, rotary drilling for underground gas drainage in coal mine and drilling for anchor net support in coal mine. Its service life is 10 to 30 times longer than that of a normal carbide drill.
PDC non coring drill bit is highly adaptable to drilling in complex rock formations, with good stability and hardness, strong wear resistance, blade strength and impact resistance, and high drilling efficiency. It is a super-hard geological diamond that can be directly connected to the drill pipe, ensuring high drilling verticality.

We are a leader in the manufacture and development of PDC bits. We provide the best quality PDC coring drills to the market. Our drill bits have been tested and verified by time, featuring wear resistance and fast drilling speeds. Different drill bits can be customized according to different rock formations, greatly shortening engineering time.
The geological drill bits have a 6-month warranty period. In case of abnormal scrap such as sheet falling, steel body cracking, or lamination of composite sheets, compensation is provided upon quality department confirmation.
