Product Description

The DHD380-203 DTH drill bit features a heavy-duty cutting structure that integrates premium tungsten carbide buttons with strategically embedded PDC cutters. The embedded PDC cutters are positioned around the gauge area to minimize wear, preserve hole diameter, and improve drilling consistency during long drilling cycles.

Designed with a concave face profile and durable dome carbide buttons, this drill bit provides efficient rock breaking, smooth cuttings evacuation, and reliable hole straightness. The heavy-duty DHD380 shank ensures stable hammer connection and efficient energy transfer, making it ideal for demanding deep water well drilling and other large-diameter rock drilling projects.
