QL50 series high-pressure down-the-hole drill bits

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

QL50 high wind pressure down-the-hole drill bit is of good quality and the material selection is very strict. It is made of alloy steel and high-quality alloy steel with advanced heat treatment to ensure good drilling performance and long service life. It is widely used by customers all over the world.

QL50 drill bit introduction

The QL50 down-the-hole drill bit uses high-quality steel and cemented carbide as raw materials. After a special heat treatment process, the button drill bit is achieved by excavating the hard rock of the button bit, and reduces the energy loss during the transmission process. 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.

QL50 down-the-hole drill bit features

Long bit life

The drill bit of this model has a long service life. The drill bit is made of cemented carbide. The wear ratio of this material is more than 10-20 times that of similar products, so the service life is greatly extended.

Wide range of use

It has a wide range of applications. Practice has proved that the bit is suitable for drilling in medium-hard formations such as carbonate rock, limestone, siltstone, and sandstone.

high working efficiency

The drilling efficiency of the drill bit is high, the hard alloy has high hardness and wear resistance, and the drill bit can always remain sharp, thus greatly improving the speed of the tooth.

Cost-effective

The drill bit is cost-effective. Because the drill bit has a fast drilling speed and long service life, the number of drilling times is small, and the drilling cost is greatly reduced.
