Symmetrix Overburdern Drilling System casing 114mm for DTH hammer DHD 3.5 with best price
 
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. 
This system is also the more efficient when it comes to drilling straight holes through bolders and other types of overburden.

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
With the industry-leading imported heat treatment technology, the hardness and toughness of the steel body are increased by 35%.
The alloy teeth adopt a professional over-pressure sintering process to greatly improve the strength of the alloy teeth.
The use of high-quality steel as the product steel body, life expectancy increased by 30%, the steel body does not break.
