PDC Bit – 3‑blade Double‑row Cutters Drill Bit

This 3‑blade PDC bit is engineered for water well drilling, geological exploration and shallow‑mine drilling. Adopting a double‑row cutter layout, it significantly improves penetration rate and impact resistance, avoids abnormal cutter chipping, and performs well in mixed soft‑hard formations.

Available standard sizes: 76mm, 94mm, 98mm,120mm,133mm, 146mm,153mm165mm,171mm,180mm,190mm,200mm215.9mm,222mm,254mm etc. Standard connections include Z‑50 female thread and 2 3/8 REG thread. Custom thread service is available, supporting NC, IF, FH and other thread types to match various drill rods and drilling rigs.

Double‑row PDC cutters distribute drilling load evenly. It reduces bit bouncing while drilling in interbedded layers, mudstone and sandstone, and extends total service life.

Suitable Formations : Mudstone, shale, sandstone, weathered granite, soft‑to‑medium‑hard interbedded strata. Not recommended for highly abrasive flint and massive boulder formations.

Application Fields : Domestic water wells, agricultural irrigation wells, pilot holes for geological investigation, shallow mine drilling, shallow geothermal hole projects.

As a direct PDC bit manufacturer , we offer custom solutions for blade quantity, PDC cutter specifications, thread types and water‑course structures. OEM bulk orders are welcome for overseas wholesalers and drilling contractors.
