Product Description

Product Description:

Overburden Casing System,  also named Eccentric Casing System, is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building, diamond harbour project.

Economy: Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole.

Working Principle:

When drilling, the reamer bit will rotate out to enlarge the hole which enough for the casing tube slide down behind the reamer. When reached required depth, the drill pipe will drill to the reverse direction and the reamer bit will retract, It is allowing the whole drilling system to pass through the casing.

Competitive Advantage:

• High grade tungsten carbide inserts

• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment

Different Shanks:



Different Faces Shapes:



Different Buttons Shapes:

A:When drilling starts working,reaming sleeve will open,borehole range will increase,which will casing shoe and casing tube.

B:When finish drilling in overburden layer,pay attention to reverse circulation,reaming sleeve circles up,eccentric drilling bit lifts out from the borehole.

C:The casing that can be left in the borehole to prevent borehole from collapsing while pulling out pipe and grouting concrete.

D:Regular drilling bits can be applied to drill the depth as required in the rock stratum.
