TND-IR380 DTH Hammer

TND-IR380 DTH Hammer Product Features:

Our TND-IR380 DTH hammer has another name of DHD380 DTH hammer. It is suitable for 8-inch (203mm) or larger drill bits, ideal for deep and large-diameter boreholes. Normally TND-IR380 DTH hammer works efficiently under 20–30 bar pressure. All the hammer parts are made from high-strength alloy steel for excellent wear resistance and durability. The simple inner structure of TND-IR380 hammer is for easy disassembly and reassembly on site, reducing downtime for customers.

• High-Impact Performance: The TND-IR380 hammer is engineered for maximum energy transmission, delivering outstanding results in deep-hole drilling.

• Enhanced Wear Resistance: Built with premium-grade alloy steel, processed in heat treatment, it provides exceptional durability against abrasive rock formations.

• Superior Air Efficiency: Our TND-IR380 hammer has an optimized airflow design that ensures consistent and efficient operation, even in the most challenging drilling conditions.

• Wide Compatibility: Our TND-IR380 hammer is the same as the market DHD380 shank, so our TND-IR380 hammer can be matchable with a range of different diameters of DHD380 shank bits, offering flexibility for various drilling setups.

All Our TND Series Hammers have the following features:

1. TND® optimized structure design: Fewer air holes on internal cylinder, higher stiffness of air slot.

2. Standard API Thread.

3. Fine CNC machining tolerance and specifications coupled with quality assembly lead to great reliability and performance.

4. The piston case is made of superior alloy steel to provide the longest service life possible.

5. 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.

6. The multiple threads are CNC machined to achieve a higher level of accuracy, allowing ease of breakout and make-up of the Driver sub. 

7. The Driver sub is heat-treated to maximize life and maximize drill bit life.

8. 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.
