Manufacturing process:
1. Smooth welding technology, beautiful and firm.
2. Surface powder coating treatment, beautiful and rust proof.
3. Precise size control, high product consistency.
4. Through strict quality inspection, control the product quality.
Design concept:
1. High usability, the inner diameter of the connecting part is 20 mm, which is suitable for most electric tools on the market and has strong practicability.
2. It adopts double helix structure, which is quick to excavate and double efficiency.
3. Spiral conical drill point. The conical drill point can reduce the resistance and drill the soil more quickly. The spiral type can bring the soil out of the hole while drilling, without blocking the hole.
4. The spiral has many smooth chamfering to prevent users from injury and high safety.
5. The blade is made of manganese steel and welded with cemented carbide, which is more wear-resistant and longer service life.
