Why Is The Drill Bit of A Rotary Drilling Rig Designed in A Spiral Shape

Have you ever wondered why the imposing rotary drilling RIGS on construction sites always carry spiral drill bits? This is not merely a simple styling design; it conceals a great deal of engineering wisdom behind it. Now, let me reveal the mystery to you.

1. Efficient soil breaking: The spiral drill bit is like an "underground sharp blade". When drilling, it can quickly cut into the soil and sand, and break the rock and soil by the rotation of the spiral blades, which is much more efficient than ordinary drill bits.

2. Continuous excavation: The crushed construction waste rises along the spiral blades and is directly carried out of the ground, eliminating the need for frequent drill lifting and cleaning. This reduces construction time and enhances overall efficiency.

3. Stable drilling: The spiral structure enables the drill bit to be subjected to more uniform force when rotating, just like installing a "stabilizer" on the drill bit. Even in complex geological conditions, it can maintain vertical drilling and ensure construction accuracy.

4. Reduce resistance: Compared with flat drill bits, the spiral design reduces the contact area with the soil, lowers the friction during drilling, saves fuel and extends the service life of the drill bit.

5. Wide application: From soft soil to hard rock, different types of spiral drill bits can handle various geological conditions. By adjusting the shape, spacing of the blades and the configuration of the drill teeth, they can meet diverse construction requirements.

6. Protecting the hole wall: During the drilling process, the rotation of the helical blades can exert certain pressure on the hole wall, making the soil on the hole wall more compact, reducing the risk of collapse, and ensuring construction safety.

The spiral drill bit of the rotary drilling rig, through ingenious structural design, achieves multiple functions such as soil breaking, soil emergence, stability and high efficiency. It is not only a powerful assistant in engineering construction, but also a vivid embodiment of modern mechanical design wisdom.
