• Optimized for Mining and Blasting: We have exported this TND-QL50N DTH hammer to many countries like Canada, South Africa, Australia, and Turkey. Widely recognized for its reliability and precision, the TND-QL50N DTH hammer is perfect for creating blasting holes and mining operations, where accuracy and speed are critical.

• Cost-Effective Solution: Benefit from reduced maintenance requirements and factory-direct pricing, ensuring a balance of quality and affordability for your projects.

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 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.

4.5''-5'' High Air Pressure DTH Hammer Working Performance:

10~30 bar (145-428 PSI) Working Pressure

Top Sub Pin Thread: 2 3/8'' API REG & 3 1/2'' API REG
