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 maximize 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.
