CASING O.D 114 mm Symmetrix Overburdern Drilling System with IR3.5 DTH hammer;Concentric system Symmetrix Casing
 
Description
 
The Prodrill symmetric drilling system is designed to drill and case a hole simultaneously through unstabled ground conditions. The driver bit incorporated with a satisficial ring or reusable ring makes a full face head design which significantly improves the penetration rate and hole straightness of drilling. The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus minimising the disruption of the surronding of the drill hole. 
 
The characteristic of high pressure series DTH hammer:
  Deliver maximum energy to drilling bits,which enables fast drilling speed and low air consumption due to the special inner structure of the DTH hammer series designed according to newest rock drilling theory .deliver smooth performance and long service life of the DTH hammer series due to the high quality tungsten carbides steel materials and the advanced processing technology.low problem rate and easy maintenance due to the simple,reliable and easy assemble  and disassemble inner structure of hammer.

Application Range: It is suitable for drilling water wells , geothermal wells , short mircopiles ,medium mini-type grouting hole of building , dam and harbour project . 
1. Ring bit and casing shoe assembly is welded to casing prior to drilling. Lock the assembly into pilot bit with hammer. The pilot bit’s upper shoulder engages the shoulder of the casing shoe. 
2. Hammer’s percussive energy is transferred through the pilot and ring bits, crushing rock . Part of impact energy advances casing. 
3. On completion of drilling and casing , the drill string with pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling . The ring bit stays in the hole , and can be recovered only if the casing is retrieved 
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
 
Advantages
Full face head desigh for faster penetration and straighter hole 
Less torque is required 
Can drilll in vertical, horizotal or any direction 
Minimize disruption to the drilled hole
