Soft / Hard Formation Water Well Drilling Tools Wild Range Drag Drill Bit
Application
Drag bits have a wide range of drilling applications including environmental, exploration, geothermal, water well, road construction, and natural gas and oilfield drilling.
Drag Bits are the perfect solutions for soil, sand, sticky clay, and grouting drilling. They are designed for higher penetration rates in softer unconsolidated formations, provide lower costs per foot. Drag Bits are more aggressive than tricone bits, and have higher speed while lower cutting action.
Drag Bit Blades
Drag Bit Blades are replacement blades for replaceable step type drag bits.
