DHD340 series high-pressure down-the-hole drill bits

DHD series high-pressure down-the-hole drill bit

DHD340 high-pressure down-the-hole drill bit is a convex type drill bit, which is mainly used for geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.

DHD340 drill face characteristics

  • Convex Face

This shape is suitable for drilling soft-medium hard rock formations with low-medium wind pressure, and 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.

DHD340 drill bit alloy tooth profile selection

  • 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.

  • Button teeth

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

DHD340 drill bit introduction

DHD340 down-the-hole drill bits use high-quality steel and best-level alloy steel as raw materials, use special heat treatment technology and advanced cemented carbide inlay technology, so that the drill bit can perform well even on hard rock formations, and at the same time Can save energy.

DHD340 drill bit technical parameters

DHD340 DTH drill bit features advantages

Long bit life

This type of down-the-hole drill is made of alloy steel material, and its quality is effectively guaranteed. Its service life is long, and it is higher than similar products, and its durability is better.

High drilling efficiency

This type of drill uses impact and shear to break rocks. The drill teeth are wear-resistant, so that the drill bit can always remain sharp, thus greatly improving the speed of the tooth.

Good compliance effect

The drill bit of this model has strong wear resistance and excellent gauge performance, which can make the cutting teeth efficiently used.

Wide range of use

The drill bit is suitable for drilling in soft, medium-hard and hard formations. Compared with ordinary drill bits, especially for drilling 6-8 rock formations, the effect is particularly significant.

DHD series products are widely used in water well drilling and hard rock formation protection. In the past 20 years, we have exported this drill bit to many countries, and the feedback is good.
