Product Description
Shaped Gear Profile Impregnated Core Drill Bits it's suitable for drilling hard dense formations with high penetration rate.

Impregnated  core bits are widely used in mineral exploration industry, site investigation, etc.
The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. The advantages of using impregnated diamond core bits over bits manufactured with other cutting media include:
An extremely wide range of application .
A simple crown geometry that makes them less susceptible to in-hole damage than bits produced with other types of cutting media and as such are more tolerant of changing or banded geological formations.
Their multi-layered cutter arrangement results in better overall bit life than bits produced with other types of cutting media. They are particularly well suited for drilling in hard, consolidated, non-abrasive formations.
 
Crown Height:
We could offers crown impreg depths of  9mm, 12mm, and 14mm .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:
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.
