Welcome to Wooke Rock Drilling Tools Co., Ltd
TND-IR340 DTH Hammer Product Features:
Precision Fit: TND-IR340 DTH hammer ensures tight alignment between the piston and driver sub, and also drill bit, minimizing energy loss and improving impact efficiency.
Wear-Resistant Material: Our hammers are made from high-strength alloy steel with heat treatment for durability and long service life.
Optimized design: The TND-IR340 DTH hammer with optimized airflow design facilitates efficient air transmission to maximize piston performance and drilling penetration rate. Besides, the modular structure allows for quick disassembly and replacement during servicing.
Reliable Thread Connection: Each of the TND IR340 DTH hammer threads is heat-treated, which provides a secure and stable connection between the driver sub and drill bit, reducing loosening during operation.
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 service 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).

↑★ 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.
4'' High Air Pressure DTH Hammer Working Performance:
10~25 bar (145-362 PSI) Working Pressure.
Top Sub Pin Thread: 2 3/8'' API REG.
