| Message: | General Introduction 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 then tricone bits, and have higher speed while the lower cutting action. Zuanlong supplies a variety of drag bits for many types of projects drilling needs, including 3 wings type bits for soft and medium formations, 4 wings, especially 4 wings chevron type for harder formations. Each of our bits is machined from a forging to exacting standards and then tipped with tungsten carbide. Mining grade tungsten carbide tips are brazed to the bits wing face for heavy duty bits. Then pin threads are CNC manufactured and wings surfaced hardening subsequently.PDC Drag Drill BitDiameter (mm)Height(mm)No of BladeNo of PDC CutterNo of NozzleNozzle Diameter(mm)9417041638~1211319542038~1213322063038~1215325063638~12Note: Customization are available url:http://www.zuanlongbits.com |
