DTH HAMMER BIT application scope:
Widely used in metallurgical, coal, chemical, building materials are not busy mines and water conservancy, hydropower, highway and railway defense construction projects, etc. Suitable for dry wind water mixing and shotgun-hole water gushing wet operation, reliable performance, is the ideal drilling hole and rock drilling equipment.
-PRODUCT PROFILE-
We have 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.

DTH HAMMER application scope:
When the impact stroke begins, piston and disc are in the upper position, air pressure passes through radial holes in the bonnet and seat into the upper chamber of the cylinder, push the piston down at high speed to impact the drill bit. When the piston goes to the spline keyway of the bushing is closed, Pressure in the lower cavity begins to rise, the center hole at the top of the piston leaves the valve rod, ventilate the upper chamber, drop in pressure end of work trip. When the piston hits the end of the bit, because of the upper and lower pressure difference, the valve disc reverses and the piston returns to the stroke repeatedly.

-DTH hammer bits benefits -
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.
-DTH hammer bits benefits -
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.
