PDC Drag Bit

PDC Drag Bit is a type of fixed-cutter drill bit designed for efficient drilling in soft to medium-hard formations. It features a stepped blade structure and high-performance Polycrystalline Diamond Compact (PDC) cutters, which shear and break rock effectively with stable drag cutting.

Key Features

Stepped Crown Design: The stepped blade profile improves cuttings removal, prevents bit balling in clay and sticky formations, and enhances cooling performance.
High-Wear Resistance PDC Cutters: Premium PDC inserts deliver high hardness, abrasion resistance and long service life.
Optimized Fluid Passages: Large water holes and smooth flow channels ensure efficient flushing and reduce clogging.
Multiple Blade Configurations: Available in 3-wing, 4-wing and 5-wing designs to suit different drilling conditions.
Strong Stability: Low vibration, smooth rotation and good directional control.

Applications

PDC drag bits are widely used in soft to medium-hard formations and various drilling projects, with typical applications including:

Water well drillingShallow to medium-depth water well construction in clay, sand, mudstone and unconsolidated strata.
Geothermal well drillingSuitable for surface and medium-depth geothermal drilling with low to medium formation hardness.
Mining exploration & core drillingUsed for prospecting, small-diameter drilling and sampling in soft to medium-hard rock layers.
Construction & foundation engineeringMicro-piling, anchor drilling, foundation pit reinforcement and civil engineering small-diameter drilling.
Oil & gas surface drillingApplied in shallow surface holes of oil and gas wells, especially in soft shale, mudstone and loose sedimentary formations.
Horizontal directional drilling (HDD)Used for trenchless pipeline crossing and underground cable laying in soft to medium formations.
