SD8 DTH HAMMER
1.Heat treated piston and internal cylinder guiding system is 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.
2.Fine CNC machining tolerance and specifications coupled with
quality assembly lead to great reliability and performance.
3.Hammer front structure design: when pulling out the hammer,the last impact of the piston would fall on the step of piston case,ensuring the safety of the driver sub splines and the retainer ring.
4.Save Lubrication Oil
5.East operation and fix
6.Longer working life
