TND-3.5N DTH Hammer

TND-3.5N DTH Hammer Product Features:

Premium Materials & Precision Manufacturing: All our hammers are crafted from high-quality raw materials with advanced CNC machining and heat treatment for superior durability.

High Efficiency: Everyone wants high-efficiency hammers. Our TND-3.5N (without footvalve）DTH hammer is an optimized design that ensures high impact frequency and reduced compressed air consumption for faster, more efficient drilling.

Reliable & Stable Performance: Due to the TND-3.5N DTH hammer's optimized design. Fewer internal components minimize service needs while maintaining smooth, stable operation.

Long Service Life: All our hammers are patented and designed by us. The patented features and strict heat treatment of key internal components maximize tool longevity and reduce maintenance requirements.

Cost-Effective: Our TND-3.5N DTH hammer is quite cost-effective. The lower operational costs due to minimized air consumption and extended tool life make the TND-3.5N DTH hammer an ideal choice for demanding applications.

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.

3'' High Air Pressure DTH Hammer Working Performance:

10~20 bar (145-285 PSI) Working Pressure.

Top Sub Pin Thread: 2 3/8'' API REG.
