NTW & HTW impregnated diamond core bits

We are a professional manufacturer of NTW & HTW impregnated diamond core bits . This series wireline coring bits covers NTW75.5, NTW76.5, NTW77.5, HTW95.6, HTW96.6 specifications. Adopting hot-pressed sintering craft with uniformly distributed synthetic diamond grains inside the metal matrix, it can continuously expose new sharp diamond cutting edges during drilling, delivering stable faster penetration rate on dense, abrasive hard rock formations.

Optimized to match full hydraulic core drilling rigs, the NTW HTW impregnated diamond core bit guarantees intact core recovery and consistent drilling performance. Widely deployed for water well drilling, geological coring, mineral resource exploration, mining engineering, foundation investigation and geotechnical survey projects. Custom matrix hardness, waterway layout and bit profile are available for different local rock conditions.
