TND-340N DTH Hammer

TND-340N DTH Hammer Product Features:

As a specialized manufacturer and provider of Down-The-Hole (DTH) drilling tools, we are pleased to introduce our newest generation of TND-340N DTH hammer. This advanced hammer incorporates cutting-edge technology, utilizes superior alloy steel materials, and features a robust design engineered for exceptional durability.

Extensive testing, validated through thousands of operational cycles, confirms that our latest DTH hammer delivers significant performance advantages over conventional market offerings. Key benefits include:

Increased Drilling Speed: Achieves penetration rates approximately 15% higher than conventional DTH hammers.

Broad Operating Pressure Range: Functions reliably within an air pressure range of 0.6 to 3.5 MPa (6 to 35 Bar), providing operational flexibility.

Furthermore, we offer a comprehensive range of hammer types designed for seamless compatibility with all major DTH bit shank standards, including DHD, COP, QL, MISSION, and SD. This ensures optimal performance and interchangeability with existing equipment.

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 service 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.

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.
