TND-M30 DTH Hammer

TND-M30 DTH Hammer Product Features:

• Our TND-M30 DTH Hammer with heat-treated piston and internal cylinder is reasonably structured to achieve the highest efficiency and the largest impacting power. The penetration speed is 10%-32% faster than other products of the same type.

• TND-M30 hammer with optimized structure design: Fewer air holes on internal cylinder, higher stiffness of air slot.

• The top sub-threads are CNC machined to achieve high accuracy, making the TND-M30 DTH hammer easy and smooth to assemble. TND-M30 Driver sub is heat-treated to achieve better abrasiveness and longer life.

• The TND-M30 DTH Hammer top sub thread is a standard 2 3/8'' API REG Thread

• The TND-M30 DTH Hammer top sub can be customized with a cement carbide button (alternative).

• The TND-M30 DTH Hammer internal parts are tightly assembled to avoid inter-active wear, and the hammer's reliability is increased.

• The TND-M30 DTH Hammer piston case: Using superior alloy steel, even better reliability, and longer life after heat treatment.

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
