DHD series high-pressure down-the-hole drill bit
DHD350 high-pressure down-the-hole drill bit is used in drilling engineering. The drill bit is made of high-quality steel and the best level of alloy steel as raw materials. It adopts a special heat treatment process and advanced cemented carbide inlay technology, so that the drill bit can perform well even on hard rock formations while saving energy.
DHD350 drill face characteristics
- Flat type
This flat head is 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.
- Convex
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.
- Concave type
This head 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.
DHD350 drill bit introduction
DHD350 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.
DHD350 drill bit technical parameters
DHD350 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.
