DTH Casing drilling systems
DTH casingdrilling systems are the preferred method for drilling in difficult groundconditions. When casing and drilling occurs at the same time, the holecollapsing risk is minimized and you can work faster and with better results. Itcontains eccentric casing drilling systems, symmetric casing drilling systems.
DTH casingdrilling systems in a wide range of applications in difficult ground conditions,such as Geothermal well drilling, Water well drilling, Pipe roofing, Foundationwork and others.
Applicable DTH hammers: DHD3.5, DHD340,DHD350, DHD360, DHD380, COP34, COP44, COP54, COP64, COP84, SD4, SD5, SD6, SD8,QL40,QL50,QL60,QL80, Mission 40, Mission 50, Mission60, Mission 80, BR2, BR3,Mach33, etc.
Eccentric casing drilling systems
Eccentric is themost economical solutions because its ingenious reaming wing the bit isretrievable can be used at the next hole.
We are able tosupply Eccentric 90, Eccentric 114, Eccentric 140, Eccentric 165, Eccentric 190and Eccentric 240 and other sizes as your request.
Symmetric casing drilling systems
Symmetric is asystem comprised of an ingeniously simple concentric method of drilling throughoverburden with casing. Symmetric candrill straight holes at any angle and it more quickly and accurately than anyother method. It will save your drilling cost and time.
We are able tosupply Symmetric 114, Symmetric 127, Symmetric 140, Symmetric 146, Symmetric168, Symmetric 178, Symmetric 195, Symmetric 219, Symmetric 243, Symmetric 273 andother sizes as your request.
