4‑Blade Curved PDC Bit

Our 4‑blade curved PDC bit is engineered for stable cutting performance under complex downhole conditions. Equipped with premium 1613, 1913 and 1916 super‑hard PDC composite cutters, this drill bit delivers outstanding abrasion resistance and impact toughness. The curved blade design optimizes rock breaking trajectory, reduces bit vibration, slows down cutter chipping, and extends overall service life during continuous drilling operations.

All thread connections can be fully customized according to project requirements, supporting mainstream specifications such as REG, NC, IF, FH, Z‑50, Z‑76 to match various drill rods and drilling rig equipment.

This 4‑blade curved PDC bit adapts to wide‑ranging formations: soft‑medium mudstone, shale, sandstone, limestone, and medium‑hard interbedded rock strata. It performs reliably in water well drilling, mineral exploration, surface mining, geothermal well projects and shallow oil‑gas prospecting.

Up to now, this PDC bit model has gained wide recognition from clients across Nigeria, Romania, Philippines, Germany, Peru and Kenya. Field feedback proves stable penetration rate and low failure rate even in tough mixed‑layer drilling environments. We support OEM & ODM customization including cutter layout, bit body material and thread parameters to satisfy diverse regional drilling demands.
