WK50 series down-the-hole drill bits

WK50 down-the-hole drill bit

WK50 is a convex type down-the-hole drill bit. This shape is 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 drilling speed is faster and the drill body wears less. The characteristic is that the tooth load is low, the wear is not serious, and the drilling speed is fast.

Advantages of WK50 DTH bit

Long bit life

The drill bit is made of alloy steel, which has a long service life and is higher than that of similar products. The wear ratio is more than 10-20 times that of similar products.

High drilling efficiency

The hard alloy used in the drill bit has high hardness, the drill teeth are resistant to wear, the drill bit can always remain sharp, and the gear feed speed is fast.

Wide range of use

Practice has proved that the drill bit is suitable for drilling in soft, medium-hard and hard formations, and the drilling effect is particularly significant.

WK50 DTH drill bit profile introduction

  • Button teeth

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

  • Bullet teeth

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

Technical parameters of WK50 down-the-hole drill bit

WK50 down-the-hole drill features introduction

WK50 down-the-hole drill bit uses high-quality steel and hard alloy as raw materials. After a special heat treatment process, the button drill bit is achieved by excavation of strong rock with strong hardness, and reduces energy loss during transmission. The tooth force is uniform and difficult. Lost teeth and teeth, so the impact energy is concentrated on the rock to achieve high efficiency driving.

WK50 down-the-hole drill bits are mainly used for geological prospecting, coal mines, water conservancy and hydropower, highways, railways, construction, etc.
