Multi-Layer Diamond Segment Core Bit with Progressive Diamond Exposure for Extended Bit Life BQ NQ HQ PQ

Multi-Layer Diamond Segment Core Bit

Revolutionize your drilling operations with our Multi-Layer Diamond Segment Core Bit, featuring innovative progressive diamond exposure technology. Fine-grade diamonds at the outer layer ensure fast initial penetration, while coarser-grade diamonds embedded at deeper layers are progressively exposed as the bit wears, maintaining peak cutting performance throughout the entire bit life with 50%+ longer service life compared to standard impregnated bits.

Key Features

• Proprietary multi-layer diamond distribution with fine-to-coarse progressive grit exposure
• Fine outer-layer diamonds (60/80 mesh) for rapid initial penetration
• Coarse inner-layer diamonds (30/40 mesh) for sustained aggressive cutting in mid-to-late life
• 50%+ longer bit life compared to conventional single-layer impregnated bits
• Consistent cutting performance maintained throughout entire wear life
• Reduced bit change frequency minimizes downtime and trip costs in deep holes
• Available in BQ, NQ, HQ, PQ standard sizes and custom specifications

Applications

• Long-distance continuous drilling programs
• Highly abrasive formation drilling where bit life is critical
• Deep hole exploration requiring minimal bit changes
• Variable rock condition drilling with mixed hardness formations
• Cost-sensitive exploration projects seeking lower per-meter drilling costs
