Symmetric Drilling Tools with Casing Tube
Retrievable Symmetric Drilling tools with casing tube
step-by-step:
1.
When the drilling starts, the central bit drives the ring bit
down the hole, meanwhile the casing shoe and casing tube follow
down together.
2.
When arriving at the bedrock, reversely rotate the tools and the
central bit is pulled out from the hole.
3.
During pouring the concretes through the casing tube, pull out
the casing tube with the ring bit synchrony.
Permanent Symmetric Drilling Tools with casing tube
step-by-step:
1.
When the drilling starts, the central bit drives the ring bit
down the hole, meanwhile the casing shoe and casing tube follow
down together.
2.
When arriving at the bedrock, reversely rotate the tools and the
central bit is pulled out while leaving the ring bit in the hole
bottom.
3.
Pour the concretes into the casing tube or move to the next
fieldwork process.

Symmetric/Centrex/Symmitrix Drilling System
Symmetric is a concentric drilling system with retrievable pilot
bits.
This system drills in any direction and in any type of ground
condition.
It is, in fact, the most flexible and efficient overburden system
on the market today.
The Symmetric components are made up of:
---A pilot bits with large internal flushing holes and external
flushing grooves
---Symmetrical ring bit (reamer) with internal bayonet
coupling
---Casing shoe for driving of casing.
The Pilot bits is attached to any common DTH hammer
shank.
