Odex Casing Drilling System 165 Pilot Bit Casing System for Geothermal 

Product Descrption 

Rock drilling tools factory KINGDRILLING professionally produce Ring wing bit concentric drilling systems by down the hole hammer which are designed to drill and case a hole simultaneously through unstable ground conditions.

A driver bit and a ring are assembled to a complete RING system bit which is suitable for 114-1067mm diameter casing tube.

KINGDRILLING provides rock drilling tools including civil engineering projects, tunneling, surface drilling, anchoring, foundation projects, and piling. This is true for all drilling methods such as top hammer, DTH and rotary drilling.

Working principle:

1. When drilling starts , the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly 
2. When the required depth is reached , rotation is reversed carefully, whereupon the reamer swings in , allowing the drill bit assembly to be pulled up through the casing. 
3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent. 
4. Drilling continues to the desired depth in the bedrock using a conventional drilling. 

Casing Overburden Drilling Tools with Ring Bits features: 
1. Hardening treatment of the surface:with longer operating life and excellent anti-wear properties 
2. Simple structure: greatly minimize the chances of structural failure, convenient operation 
3. superior performance:take care of both the drilling wear life.
