When only the best will do, our Premium AAA Grade Natural Diamond Surface Set Core Bit delivers unmatched performance in the world's hardest and most abrasive rock formations. Each diamond is hand-selected from AAA-grade (40/60 SPC) natural diamond stock and individually set in a multi-step crown profile, providing superior cutting ability and exceptional lifespan in quartzite, chert, taconite, and jasperite formations where synthetic diamond bits fail prematurely.
Multi-step crown profile provides progressive cutting action through ultra-hard formations
Superior performance in BST 14 hardness formations (quartzite, jasperite, chert, taconite)
Exceptional lifespan — outlasts synthetic diamond bits by 2-3x in highly abrasive rock types
Natural diamond thermal conductivity enhances heat dissipation during drilling
Available in BQ, NQ, HQ, PQ standard sizes with custom sizing available
Rigorous individual quality inspection for each bit
Applications
Ultra-hard rock formations (BST 14: quartzite, chert, jasperite, taconite)
Highly abrasive iron ore exploration and grade control drilling
Special exploration projects requiring maximum core recovery in difficult ground
Precambrian shield and crystalline basement drilling
Deep hole programs where bit life directly impacts project economics
