5‑Inch 5‑Blade Concave Standard PDC Bit

Our 5‑inch 5‑blade concave standard PDC bit is a versatile rock‑cutting tool engineered for stable penetration performance in medium‑hard formations. Equipped with Z‑50 female thread as standard connection, this concave‑face PDC design delivers excellent centering effect at the start of drilling, reduces bit wandering, and keeps smooth borehole quality during continuous drilling operations.

Standard available sizes cover 4 inch, 4.5 inch, 5 inch, 6 inch, 6.5 inch, 8 inch, 9 inch. Beyond the listed stock dimensions, we support full customization: custom thread types (replace Z‑50 female thread upon request) and any non‑standard bit diameter according to client’s drilling project parameters.

Applicable Formations

Best suited for soft to medium‑hard rock layers: clay, shale, mudstone, sandstone, limestone, weathered rock and mixed interbedded strata. Performs steadily in abrasive medium formations, less fit for extremely hard massive granite.

Working Conditions & Project Scenarios

Ideal for water well drilling, surface mineral exploration, geothermal shallow drilling, civil engineering foundation investigation, small‑scale open‑pit mining drilling. It matches well with medium‑sized portable drill rigs and truck‑mounted drill rigs. The concave structure helps clean cuttings efficiently, lowers bit wear in long‑shift field jobs.
