Description
Inquiry

STAROCKDRILL’S DTH hammers mainly be produced with shank type of DHD, QL, NUMA, COP, Mission, SD, BR, CIR,TD.40 MACH44 and STR series,

Diameter ranging from 2” to 8” for mining and quarrying, and 6” to 32” for water-well drilling, oil-well drilling and foundation and so on

Advantage:

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
