Overview of Drag Bit

The step carbide insert drag bit is a fixed-cutter drag bit with a stepped blade profile, fitted with hard tungsten carbide inserts (TCI) instead of PDC cutters. It is designed for abrasion resistance and durability in soft to medium-hard, abrasive formations.

A drag bit is usually designed for soft formations such as sand, clay or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to log.

Drag bit are manufactured from forged high-quality alloy steel and hard alloy, plus state of art welding technology and multiple precision heat treatment to provide the highest penetration rate and longest lifespan at the roughest condition.

Three-wing bits tend to drill faster, whereas four-wing bits are longer-lasting, more durable, and drill a straighter hole.

 Features

• Stepped crown design: Multi-level cutting structure improves cuttings evacuation, reduces balling, and enhances drilling stability.
• Tungsten carbide inserts: High-strength tungsten carbide buttons or blades provide excellent abrasion resistance and impact resistance.
• Robust body construction: Heavy-duty steel body with reinforced wings for long service life in harsh drilling conditions.
• Optimized flow paths: Large water holes and flushing channels ensure efficient cooling and cleaning.

Application

Step carbide insert drag bits are mainly used for soft to medium-hard, abrasive formations in general drilling projects.

• Water well drillingShallow to medium wells in sand, clay, gravel, and unconsolidated formations.

• Geothermal well drillingSurface and medium-depth geothermal drilling in low-abrasion strata.

• Mining & exploration drillingProspecting, small-diameter drilling, and sampling in soft to medium rock.

• Construction & foundation engineeringMicro-piling, anchor bolts, foundation reinforcement, and civil engineering drilling.

• Horizontal directional drilling (HDD)Trenchless crossing for pipelines, cables, and utility installation.

• Shallow oil & gas surface holesTop-hole drilling in mudstone, shale, and soft sedimentary formations.

Suitable Formations

• Clay, silt, sand, and gravel layers
• Mudstone, shale, and argillaceous sandstone
• Soft to medium-hard limestone and dolomite
• Weakly consolidated and abrasive formations

Performance Advantages in Application

• High abrasion resistance in sandy and gravelly formations
• Good anti-balling performance in clay
• Stable drilling with low vibration
• Lower cost than PDC bits and longer life than steel drag bits
