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
