QL series high-pressure down-the-hole drill bits
QL80 is a concave high-pressure down-the-hole drill bit. This bit shape is suitable for all rock formations, especially in medium-hard and uniform rock formations, with small blast hole deviation and good slag discharge effect.
QL80 drill bit introduction
The QL80 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.
QL80 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.
