1. Non-Blocking:Our S-series DTH hammers are proved to ensure extremely low rate of blocking during it works.
2. High Efficiency:The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
3. Longer Service Life:All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.
4. Excellent Cleaning Effect: This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.
Scope of application:
Mining, quarry, road building, well hole drilling, blasting, landslide prevention, dam reinforement, anchoring, geothermal, hydrology, etc.

To Chose the Right Products
When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration, remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life. our commonly hasthree basic bits head designs: Flat Face, Convex and Concave. These are designed for specific applications for all rock types, hardness’s and conditions:
Bit Face Shape Selection:
Center Drop Bit:
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressure. Maximum hole deviation control.
Concave Face
The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash and may reduce the load and wear on gauge buttons, but poor hole deviation control.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressure and good resistance to steel wash step gauge bit.
Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formation is applications with high air pressure. Good penetration rates and resistance to steel wash.
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
