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.
Specifications
1. with face discharge holes
2. stable quality,full range of products
3. delivery timely
4. used for mining
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.
