Mission series down-the-hole drill bits

HM5C series flat-type drill bits are suitable for drilling very hard rock formations and corrosive rock formations under high wind pressure. The drilling speed is faster and the drill body wears less.

HM5C 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 HM5C 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.

HM5C series drill bit technical parameters

Drill product introduction

This drill 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.
