The 75-350mm Non Coring PDC Concave Drill Bit is a full-scale drilling tool engineered for high-efficiency penetration in soft to medium-hard rock formations. Featuring a concave geometry with 3, 4, or 5 wings/blades, this bit is crafted from a high-quality alloy steel body integrated with PDC (Polycrystalline Diamond Compact) cutters.
The non-coring design enables rapid hole creation without extracting a core sample, making it ideal for applications where core recovery is not required. Available in diameters ranging from 75mm to 350mm, with customizable thread types (male or female, API standard) and blade configurations, this bit offers exceptional wear resistance, impact toughness, and drilling efficiency. Its service life is 10 to 30 times longer than that of conventional carbide drill bits.
