Big Diameter 3 Parts Eccentric Casing Drilling System with Pilot Bit

Product Description

When drilling in soft and loose ground with scattered boulders, the soil and clay are caved in, which creates drilling difficulty to withdraw the DTH drilling equipment and lowers the drilling speed. To overcome this problem, KINGDRILLING Eccentric Type Overburden Casing Drilling System to enable drilling and lowering the casing simultaneously. This prevents the soil from collapsing into the drilled hole. The systems are designed to drill the hole diameters bigger than the casing diameter. When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole. If the bed-rock level is reached and further drilling is needed, you can simply change the bit to a conventional DTH bit.

MK5E Eccentric casing drilling system comprises guide device, lock pin, reamer, spring pin, pilot bit.

1. Application range
It is suitable for drilling water wells, geothermal wells, short micropiles, medium mini-type grounting hole of building, dam and harbour project.

2. Outstanding Advantage
Simple structure, easy operation, reliable quality, retrievable drilling tools and long service life.
 

 

Technical date

How to choose the suitable head face of the DTH drill bit?

1.  Concave:

Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.

1.  Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

1.  Flat:        

Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.

Product Application

It is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building , dam and harbour project.
