Medium/Low wind pressure DTH Drill bit,High wind pressure DTH Drill bit
Fast drilling and retrieval!High efficiency, low labor intensity of workers!
DTH HAMMER application scope:
When the impact stroke begins, piston and disc are in the upper position, air pressure passes through radial holes in the bonnet
and seat into the upper chamber of the cylinder, push the piston down at high speed to impact the drill bit. When the piston goes
to the spline keyway of the bushing is closed, Pressure in the lower cavity begins to rise, the center hole at the top of the
piston leaves the valve rod, ventilate the upper chamber, drop in pressure end of work trip. When the piston hits the end of the
and seat into the upper chamber of the cylinder, push the piston down at high speed to impact the drill bit. When the piston goes
to the spline keyway of the bushing is closed, Pressure in the lower cavity begins to rise, the center hole at the top of the
piston leaves the valve rod, ventilate the upper chamber, drop in pressure end of work trip. When the piston hits the end of the
bit, because of the upper and lower pressure difference, the valve disc reverses and the piston returns to the stroke repeatedly.

FAQ
1.The Quality of Drill bit?
We have many series of rock bits,quality grades and prices are different.We believe that the proper tools with higher cost-performance is the most impormant.For example,our top quality rock bits is not cost-effective for water well drilling,as the water well drilling machine can not drive the super rock bit to perform their best.but for very deep well drilling high quality grades rock bits is cost effective even its price is much higher.So it is better tell us as more as possible the details of projects,then we provide the proper solutions and offer,usually 2 or 3 solutions wil be provided for options.
2.Trade Assurance
Answers:we have joined the Trade Assurance on Alibaba to protect your payment to make sure that we deliver on time and manufacture quality products as required.
3.How to send inquiry?
It is better send us detailed specificaltions of products,it is better attaching some photos for better understanding.If you are not experienced on drilling fields,for example,many customers don't know IADC code,please feel free,jusst tell us the applications like oil/gas/geothermal/HDD/ware/mining,depth of well,average hardness of rocks,then we will advise suggestions and solutions.You can:-Send us inquiry from Alibaba.com platform.-Send email to us directly or talk on Skype or Whatsapp,salespersons are always waitting for service in working days,and all the inquiries can be replied within 10 hours.
