Product Description

Three cone drill bits have excellent drilling efficiency. Due to its unique cutting structure and working principle, it can quickly break rocks and improve drilling speed. At the same time, the wear resistance and high temperature resistance of the drill bit are also excellent, which can maintain stable performance under long-term and high load working conditions.

In addition, the three cone drill bit also has high drilling accuracy. Its precise cutting structure and stable drilling performance enable the drill bit to accurately control the diameter and shape of the wellbore, improving drilling quality.
