The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. The advantages of using Impregnated Core Bits over bits manufactured with other cutting media include：
1. Their multi-layered cutter arrangement results in better overall bit life than bits produced with other types of cutting media.
2. They are particularly well suited for drilling in hard, consolidated, and non-abrasive formations.
3. It has a wide range of applications.
4. A simple bit crown geometry that makes them less susceptible to in-hole damage than bits manufactured with other types of cutting media and such are more tolerant of changing or banded geological formations. https://www.speedmadedrill.com/d...pregnated-core-bits.html
