Product Description

The DHD360-165 DTH hammer bit features a concave face design with 19 dome carbide buttons and DHD360 shank. Engineered for water well drilling applications, it delivers good hole deviation control and excellent flushing capacity in medium hard to hard rock formations.

Embedded PDC Cutters for Reliable Deep Hole Drilling

The DHD360-165 DTH drill bit is engineered with strategically embedded premium PDC cutters to improve gauge protection and drilling stability during deep hole operations. By reinforcing the gauge area with wear-resistant PDC cutters, the bit maintains consistent hole diameter while reducing edge wear in abrasive formations.

Combined with a concave face design and high-strength dome carbide buttons, this hybrid drilling structure delivers smooth penetration, excellent hole straightness, and dependable performance throughout extended drilling cycles. It is particularly well suited for water well drilling, geothermal wells, and foundation projects where drilling accuracy, durability, and long service life are essential.
