Structure Feature:
1. Standard API Thread
2. Top sup with cement carbide button (Alternative)
3. Internal parts are highly assembled to avoid interactive wear and the hammer's reliability is increased.
4. Piston case: Using superior alloy steel, even better reliability and longer life after heat treatment.
5. 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.

In order to increase the working life of the piston case when drilling every abrasive rock, the driver sub is designed to be made up of three pieces and only the wear-proof casing needs to be replaced timely.

Heat-treated piston and internal cylinder guiding systems are reasonably structured to achieve the highest efficiency and the largest impacting power. The penetration speed is 10%-30% faster than other products of the same type.

TND optimized structure design: Fewer air holes on the internal cylinder, highest stiffness of air slot.

The multiple threads are CNC machined to achieve high accuracy, making the bit easy and smooth to get assembled. Driver sub is heat treated to achieve better abrasiveness and longer life.
