Mission40 series high-pressure down-the-hole drill bits

Mission series down-the-hole drill bits

Mission40 series convex drill bits are suitable for low-medium wind pressure drilling in soft-medium-hard rock formations. The steel body of the drill bit is not easy to corrode. The tooth load is low, the wear is not serious, and the drilling speed is fast.

Mission series drill bits are mainly used in geological prospecting, coal mines, water conservancy and hydropower, highways, railways, bridges, construction, etc.

Mission40 series drill bit alloy tooth profile selection

  • Button teeth

Application: DTH drill bit side teeth, suitable for abrasive and very hard rock.

  • Bullet teeth

Application: The middle tooth of the down-the-hole drill bit is suitable for rocks with medium abrasiveness and medium hardness. Edge teeth can also be used when the rock is relatively soft.

Advantages of Mission40 drill bit

Long bit life: the wear ratio of cemented carbide is more than 10-20 times that of similar products, so the life is greatly extended
Wide range of application: Practice has proved that this bit is suitable for drilling in carbonate, limestone, claystone, siltstone, sandstone and other medium-hard formations.
Long bit life: the wear ratio of cemented carbide is more than 10-20 times that of similar products, so the life is greatly extended
High cost performance: Because of the fast drilling speed and long life, the number of drilling times is small, the drilling cost is greatly reduced, and the price is superior.

Mission40 series drill bit technical parameters

Mission series drill product introduction

Mission series bit uses high-quality steel and cemented carbide as raw materials. After a special heat treatment process, the button bit is achieved by excavating the hard rock of the button bit, and reduces the energy loss during the transmission process. The teeth are uniformly stressed and not easy to fall off. Teeth and teeth, so the impact energy is concentrated on the rock to achieve high efficiency driving.
