Description

SINODRILLS 3 Wings Air Flush Step Drag Bits

3 wings air flush step drag bits are one piece construction of alloy steel forged or cast with Tungsten Carbide cutting tips and gauge sides to ensure longer life. This step drag bits have 3 wings and 9 air flushing holes. Its wings distribute in the body of bit equably and the angle between each wing is 120 degree. Size of their 3 steps in the wing gradually becomes small, which can increase penetration ability and propulsive force. More flushing hole can improve capability of debris flushing .

Features of 3 Wings Air Flush Step Drag Bits

3 Wings Air Flush Step Drag Bits are expertly designed for optimized performance in soft to medium-hard unconsolidated formations, particularly where air is used as the flushing medium. Their construction emphasizes durability and efficient cutting action:

A solid one-piece body, meticulously heat-treated from 4140 alloy steel, ensures exceptional bit strength and durability for prolonged use in demanding drilling environments.
Precision CNC threaded machining guarantees proper and secure installation, facilitating reliable connection to the drill string and preventing operational issues.
The forgings are precisely milled, creating ideal seats for the carbide inserts, which ensures they are perfectly positioned and securely held to maximize cutting effectiveness.
Standard 5.5mm thick, select tungsten carbide inserts are incorporated, chosen for their superior wear resistance and capability to effectively penetrate diverse soft to medium-hard ground.
Hand-ground relief behind each carbide insert is a critical feature that ensures optimal air flow and chip evacuation, preventing material buildup and enhancing overall drilling performance, especially in sticky conditions.

3 Wings Air Flush Step Drag Bit Applications

3 Wings Air Flush Step Drag Bits are specifically designed for efficient drilling in soft to medium-hard unconsolidated formations, excelling where air is the primary flushing medium. Their ability to rapidly clear cuttings makes them highly effective in environments where traditional fluid flushing might be problematic or undesirable.

These specialized bits are frequently utilized in a variety of industries that benefit from their quick penetration and excellent chip removal capabilities in specific ground conditions. Their design ensures smooth operation and extended bit life, particularly when dealing with dry or sticky materials.

Mining: Ideal for blast hole drilling and exploration in coal, potash, and other soft mineral deposits where fast penetration and efficient dry cutting removal are crucial for productivity and avoiding contamination of the material.
Environmental: Used in environmental sampling, monitoring well installation, and remediation projects, especially in areas with soft soils, sand, or clay where air flushing helps maintain sample integrity and minimizes fluid-related issues.
Water Well Drilling: Highly effective for drilling water wells in formations like sand, clay, and gravel, where the air flush system efficiently removes cuttings and helps prevent bit balling in sticky ground, leading to faster progress.
Geothermal Drilling: Applied in geo exchange boreholes, particularly in softer geological strata where air flushing can provide an economical and efficient way to clear the hole while maintaining optimal drilling parameters.
Geotechnical Investigations: Employed for site investigations and shallow exploration in unconsolidated formations where precise hole cleaning and minimal disturbance are desired, often allowing for quicker completion of sampling.
