6' Tnd Down The Hole Hammers For Dhd360 Dimension(l*w*h): 140x17x20 Centimeter (Cm)

Our organization is dedicatedly engaged in the business of manufacturing and supplying an excellent quality spectrum of 6'' TND Down The Hole Hammers for DHD360 in Yichang, Hubei, China.
Hole Range: A,152-A,254
Work Pressure: 8-30 bar
Air consumption: 10bar - 8.7m3/min
18bar - 14.5m3/min
24bar - 25m3/min
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 hammer's reliablity 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 piston case, ensuring the safety of the driver sub splines and the retainer ring.

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

Heat treated piston and internal cylinder guiding system 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.
