TND-SD6 DTH Hammer Product Features:

Large-Diameter & High Efficiency

TND-SD6 DTH Hammer is designed for 6-inch (152mm) boreholes, suitable for medium-hard to extremely hard rock (e.g., granite, basalt).
The TND-SD6 DTH Hammer has an impact energy transfer efficiency >90%, single blow energy up to 1,500-2,000 Joules, increasing ROP by 30%.

Low Air Consumption

Besides, the TND-SD6 hammer has an optimized airflow path that operates at 1.05-2.46 MPa with air consumption ≤24 m³/min, reducing compressor load.

Extended Service Life

Carburized alloy steel piston + piston case of the TND-SD6 DTH Hammer improves fatigue resistance by 50%;
TND-SD6 DTH Hammer's simple inner part structure design cuts replacement time by 40%.

All our TND Series Hammers have the following features:

TND® optimized structure design: Fewer air holes on internal cylinder, higher stiffness of air slot.
Standard API Thread.
Fine CNC machining tolerance and specifications coupled with quality assembly lead to great reliability and performance.
The piston case is made of superior alloy steel to provide the longest service life possible.
Heat-treated piston and internal cylinder guiding system is reasonably structured to achieve the highest efficiency and the largest impact power. The penetration speed is 10%-30% faster than other products of the same specification.
The multiple threads are CNC machined to achieve a higher level of accuracy, allowing ease of breakout and make-up of the Driver sub.
The Driver sub is heat-treated to maximize life and maximize drill bit life.
Hammer front structure design: when pulling out the hammer, the last impact of the piston would fall on the step of the piston case, ensuring the safety of the driver sub-splines and the retainer ring.

Top Sub for Customer's Choice:

↑★ Top sub with cement carbide button (Alternative).

TND-SD6 DTH Hammer

↑★ In order to increase the working life of the piston case when drilling very abrasive rocks. The Top sub is designed to be made up of three pieces of coupling,

and only the wear-proof casing needs to be replaced timely.

6'' High Air Pressure DTH Hammer Working Performance:

10~35 bar (145-507 PSI) Working Pressure.

Top Sub Pin Thread: 3 1/2'' API
