Product Description

The 190mm DHD360-190 DTH drill bit is designed for deep water well drilling applications. Reinforced with embedded premium PDC cutters and equipped with a three-air-hole configuration, it delivers efficient cuttings evacuation, stable drilling performance, and extended service life in hard and abrasive rock formations.

Embedded PDC Cutters for Small-Diameter Precision Drilling

The DHD360-190 DTH drill bit combines premium dome tungsten carbide buttons with strategically embedded PDC cutters to create a durable hybrid drilling structure. The embedded PDC cutters strengthen the gauge area, reducing wear while maintaining consistent hole diameter throughout extended drilling operations.

Unlike conventional two-air-hole drill bits, the DHD360-190 features a three-air-hole configuration that improves compressed air distribution and accelerates cuttings removal. This enhanced airflow helps keep the drilling face clean, minimizes regrinding of rock fragments, and supports more efficient penetration during deep hole drilling.

Its concave face profile further improves drilling stability and hole straightness, making the DHD360-190 an excellent solution for water well drilling projects requiring high productivity and long service life.
