There are four main types of end face designs used in high-pressure down-the-hole drills: convex end face, flat end face, concave end face and deep concave central end face. Cemented carbide is mostly used in the common tooth distribution mode of ball teeth, spring teeth or ball teeth and spring teeth. 1, the end face convex type: the drill bit is divided into single boss and double boss end face two forms, the latter is mainly used for larger diameter down-the-hole drill. The convex down-the-hole drill can maintain a high drilling speed when drilling into hard and hard abrasive rocks, but the straightness of the drilling is poor, so it is not suitable for rock drilling projects with high straightness requirements.
Demand Market and Maintenance of DTH Bits
2022-07-08
Where is the demand market and direction of DTH drill bits? With the continuous rise of fuel prices, the operating efficiency of construction machinery has become a very important indicator in engineering projects. The selection of high-efficiency rock drilling machinery requires the configuration of high-quality and efficient rock drilling tools. In order to improve the drilling efficiency of the drilling tool and the service life of the drill bit, the research and development team with a large number of instruments also made some adjustments to the structure of the medium and high pressure down-the-hole drill bit, such as some adjustments to the tooth structure of the column teeth on the end face of the drill bit.
Hot spot of the week! What are the major global mining events this week?

The main mining-related contents are as follows: first, by 2025, the energy efficiency of key products in iron and steel, petrochemical, non-ferrous metals and other industries should reach the international advanced level, and the energy consumption per unit added value of industries above scale will be reduced by 13.5 compared with 2020. Second, we should deeply tap the energy-saving potential of iron and steel, petrochemical, non-ferrous metals and other industries, promote the upgrading of technology and process in an orderly manner, promote the level of energy efficiency, and achieve steady improvement of industry energy efficiency. The third is to accelerate the innovation and upgrading of key materials such as high-performance magnet wire, rare earth permanent magnet, high magnetic induction and low loss cold-rolled silicon steel sheet. Fourth, in accordance with the principle of "gas-based reform" to promote industrial coal-fired natural gas substitution in an orderly manner.
Preparation method and process of drill bit

The cross drill bit has four drill bits arranged in a cross. Under the condition of rock drilling with large impact power, it is used to excavate fractured rock layers and rock layers with strong wear resistance. However, the cross drill bit has strong radial wear resistance, and when drilling rock, the gap of the drill bit is easy to block stones and the drilling efficiency is low. Then, let's learn about the preparation method and process of the lower drill bit together!
