PDC Bits

4-Wing Concave PDC Bit for Water Well & Mining Drilling

Our factory supplies high-performance 4-wing concave PDC bits designed for tough water well drilling and open-pit mining projects. Manufactured in-house, this PDC drill bit adopts a concave centered structure with four strengthened blades, delivering excellent centering performance, stable drilling trajectory and strong anti-jamming capability in complex stratums.
The 4-wing concave PDC bit is equipped with premium polycrystalline diamond compact cutters. It maintains fast penetration rate while improving bit stability when drilling clay, sandstone, limestone, weathered rock and mixed broken formations. The optimized water channel design ensures smooth cuttings removal, effectively reducing cutter abrasion and extending service life.
We tailor specifications according to client demands, including various diameters, thread types and PDC cutter models. This drilling tool gains wide recognition among drillers and drilling contractors across Africa, Russia, Southeast Asia and other emerging drilling markets.
Core Application Scenarios:
Water well drilling: Domestic water wells, agricultural irrigation wells, shallow geothermal boreholes.
Mining drilling: Exploration boreholes, blast hole drilling, mine ventilation holes.
Suitable for soft to medium-hard rock formations, mixed soil-rock strata.
Product Advantages:
  1. Four-blade concave design: Good self-centering, low deviation, stable drilling direction.
  2. Strengthened blade base: Resist impact and reduce blade cracking under complicated ground conditions.
  3. Rational fluid passage: Efficient rock chip discharge, prevent bit balling in sticky clay.
  4. Customizable connections: NC, REG, API standard threads to match most domestic and imported drilling rigs.
  5. Factory direct supply: Stable lead time, competitive factory price, support OEM & ODM for bulk importers.
