How to order:
Casing Tube OD & ID + Reamer Bit Diameter + Minimal Casing Shoe ID + Hammer Shank Style
Working principle:
At clockwise condition, reamer bit expanded to bring the casing tube into hole. After finished, reamer bit closed anticlockwise and then can be lift up by the drilling machines. This casing drilling bit is especially suitable for diameter 114-273mm.
Application Range:
It is suitable for drilling water wells, geothermal wells, short micro piles ,medium mini-type grouting hole of building , dam and harbor project .
RFQ:
What is overburden fill?
Overburden Soil is a general, unprocessed, fill material that can contain a variety of different materials, depending on where it is sourced. Overburden Soil can contain sand, rocks, clay and stones, and will typically lack the organic material and nutrients found in topsoil.
What is odex drilling?
ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing. Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground. Rapid removal of cuttings.
