Impregnated diamond Core Drill Bits BQ NQ HQ PQ Longer life for
mining exploration core drilling
Impregnated diamond Core Drill Bits BQ NQ HQ PQ Longlife for mining
FACE DISCHARGE WATERWAYS (FD)
Recommended for very soft and broken ground or swelling core
applications with Q®3 barrels. The face discharge ports offer
excellent flushing to prevent blockages in the waterway
channels by reducing pressure to the ID and redirect fluid to
the face of the bit. Also available in WIDE waterway
configurations.
Size:
Longlife diamond core bits are available in all standard
drilling sizes. Also, non-standard sized bits can be produced
according to requirements from clients.
Crown Height:
We could 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 flu
shing in various ground conditions and drilling systems.
Matrix:
The 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.
