PEARLDRILL has a comprehensive range of DTH drill bits to match all conceivable applications. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are deigned for specific applications for all rock types, hardness's and condition. Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.

The ball tooth:
It is mainly used for DTH drill bit edge teeth, suitable for very hard rocks with strong abrasivity.
Parabolic tooth:
It is mainly used in DTH drill bit side and middle teeth, suitable for rocks with medium and hard wear.
Warhead tooth:
It is mainly used in DTH drill bit middle teeth, suitable for abrasive medium hardness medium rocks. The soft rock can also be made edge teeth.
Sharp tooth:
Mainly used in DTH drill bit middle teeth, suitable for soft rocks with high drilling speed and low tooth fracture rate.
1.Due to the special internal structure of the DTH hammer designed according to the latest drilling theory, it can provide the maximum energy for the bit, with high drilling speed and low gas consumption.
2.Due to the use of high-quality alloy steel materials and advanced processing technology, the performance of DTH hammer is stable and its service life is long.
3.Because of the simple and reliable internal structure, the hammer is easy to disassemble, low failure rate and easy to maintain.
4.Due to the multi thread connection of chuck and hydraulic cylinder, it is easy to separate the drill from the hammer.
5.Interchangeable with DTH bit and drill pipe.Our company provides low pressure DTH Drill bits and off center DTH Drill bits.
We can make different specifications and different forms of alloy ball bit according to different needs of users.It is widely used in mining, tunnel excavation, underground plant excavation and other construction sites.It is an ideal substitute for the same type of ball bit abroad, with stable quality and high cost performance.
