Product Description
The DHD380-275 DTH hammer bit features a concave face design with dome carbide buttons and DHD380 shank type. Engineered for water well drilling, PV micro pile, and solar energy hole drilling applications, it delivers superior drilling efficiency in medium hard to hard and abrasive rock formations.
Embedded Premium PDC Cutters for Maximum Wear Resistance
The DHD380-275 DTH drill bit is equipped with strategically embedded premium PDC cutters to provide superior wear resistance and long-lasting drilling performance in large-diameter boreholes. Positioned around the gauge area, the PDC cutters minimize edge wear, maintain hole diameter accuracy, and improve overall drilling stability throughout extended drilling operations.
Designed for demanding water well drilling, photovoltaic (PV) foundation construction, and deep foundation projects, this hybrid bit combines premium dome carbide buttons with embedded PDC cutters to achieve higher penetration efficiency and a longer service life. The reinforced cutting structure performs exceptionally well in abrasive and hard rock formations, helping reduce bit replacement frequency and overall drilling costs while ensuring reliable performance in continuous drilling applications.
Features
· Concave Face Design – All-around application rock drill bit face specifically for medium hard and homogeneous rock formations. Provides good hole deviation control and excellent flushing capacity.
· Dome/Hemispherical Carbide Buttons – Universal buttons for all rock formations, best suited to hardest and very abrasive rock formations.
· DHD380 Shank Type – Compatible with DHD380 series DTH hammers for reliable performance.
· Optimized Button Layout – 12 gauge buttons (φ18mm) & 8 face buttons (φ16mm) & 20 concave buttons (φ16mm) for balanced cutting action.
· Versatile Applications – Suitable for water well drilling, PV (Photovoltaic) micro pile, and solar energy hole drilling.
