Alloy Steel Dth Drilling System , Outside Diameter 273mm DTH Drilling Tools

273mm Concentric Casing System with wings, working with 8inch DHD380 DTH Hammer
 
 

 
Application Range:

Applies to loose covered land surface,such as soil, clay, weathered rock strata,sand and so on.
Design Principles:

1) The locking kits of the spring pin were processed by the heat treatment,which strength the body and extend the service life.

2) Pin structure improved,solved the problem of wings dropped off which cause by spring pin.
Operation Procedure

1.When drilling starts,the wing system drives the casing shoe and casing tube down.

2.When the drilling in overburden formation is finished,revise the rotation and pull the drill rod,Hammer,wing system out from the casing tube.

3.Grouting or continues to next step

4.Using the normal drilling tools to drill and achieve to the desired depth.

 
Steel:
first class special alloy steel with high strength, heat resistance and wearable
Carbide
The best tungsten carbides from China are commonly applied.
Tungsten carbide from European is also available.
 
 

• 1. Drill in overburden unstable rock.
• 2. One step to drill and follow casing
• 3. Flexible to open or close.
