High Penetration Rate Core Drill Bit BW Diamond Casing Shoe Bit
Impregnated Rod Shoe Bit
BW Casing Shoe
The casing shoe bits (rod shoes bits) are designed to drill in
casings or rods in difficult over burden material to position the
rods or casing in the drilling hole. The interior is smooth and
sufficiently large enough to allow free passage of coring equipment
such as bits, reaming shells core barrels and drill rods. They are
manufactured to withstand difficult drilling conditions: for
example, unconsolidated overburdened or broken abrasive materials.
Impregnated Casing Shoes Bits
Impregnated casing shoe bits are recommended for very hard and
fractured formations. They can be manufactured in all series and
varying impregnation heights to suit your individual requirements.
Notice:
To select the right bit for the job, assess the speed and power of
your drill for the size and depths of the holes to be drilled and
assess ground conditions such as rock type/formation and down-hole
conditions.
Size:
ROSCHEN bits are available in all standard drilling sizes . Also,
non-standard sized bits can be produced according to requirements
from clients.
Crown Height:
ROSCHEN offers crown impreg depths of 9mm, 12mm, and 16mm .The
taller crown heights provide improved bit stability and reduced
vibrations, enhancing bit life and performance.
Waterways:
Various waterways are available for diamond impregnated bits.
Differing waterways allow for better flushing in various ground
conditions and drilling systems.
Matrix:
ROSCHEN impregnated bits matrices can be selected by our engineer
according to ground conditions at client's work site.
Threads:
standard Q threads as well as thread types required by clients are
available.
Size Available:
Q Series: BQ, NQ, HQ, PQ
