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.
