Premium AAA Grade Natural Diamond Surface Set Core Bit for Ultra-Hard Abrasive Rock Formations BQ NQ HQ PQ

AAA Grade Natural Diamond Surface Set Core Bit

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.

Key Features

• AAA-grade (40/60 SPC) natural diamonds individually hand-set for optimal cutting exposure
• 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
