Product Description
The DHD360-203 DTH hammer bit features a concave face design with 24 dome carbide buttons and DHD360 shank. Engineered for water well, mining, and construction drilling, it delivers good hole deviation control and excellent flushing capacity in medium hard to hard and abrasive rock formations.
Embedded Premium PDC Cutters for Maximum Wear Resistance
The DHD360-203 DTH drill bit is engineered with embedded premium PDC cutters to enhance wear resistance and protect the gauge area during high-impact drilling operations. Working together with heavy-duty dome carbide buttons, the PDC cutters reduce gauge wear, maintain hole accuracy, and improve overall drilling stability in demanding ground conditions.
Designed for large-diameter mining blast holes and deep water well drilling, this hybrid cutting structure provides reliable penetration, excellent impact resistance, and an extended service life. The optimized cutter arrangement minimizes premature wear while maintaining consistent drilling efficiency in medium-hard to hard and abrasive rock formations.
Features
· Concave Face Design – All-around application bit face specifically for medium hard and homogeneous rock formations. Provides good hole deviation control and good flushing capacity.
· 24 Dome Carbide Buttons – 10 gauge buttons (φ19mm) + 8 face buttons (φ16mm) + 6 face buttons (φ18mm) for balanced cutting action and long service life.
