Drag Bits: Acedrills supplies a variety of drag bits for many types of projects drilling needs, including 3-wing type bits for soft and medium formations, 4-wing, especially 4-wing 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 bit wing face for heavy duty bits. The pin threads are CNC manufactured and wings surfaces hardening subsequently.

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.
