The short spiral drill bit is widely used in rotary drilling construction, especially in the drilling of gravel, pebble, cohesive soil, and soft rock.

1. Gravel and pebble formations: The short spiral drill bit has strong crushing and soil removal capabilities, which allows it to effectively drill into and crush gravel and pebble formations. The debris and soil can then be expelled from the hole, facilitating drilling operations.

2. Cohesive soil formations: Due to its compact structure and excellent anti-adhesive properties, the short spiral drill bit is suitable for drilling in cohesive soil formations with high stickiness. It has good soil removal capabilities, making construction in these conditions less challenging.

3. Soft rock formations: The short spiral drill bit has high crushing and compressive capabilities, enabling it to penetrate soft rock formations and complete drilling operations by crushing the rock and removing the debris from the hole. This contributes to smooth construction processes.

Overall, the short spiral drill bit is a versatile tool in rotary drilling construction, offering capabilities such as crushing, soil removal, and penetration. It finds widespread application in various types of geological formations, allowing for efficient and effective drilling operations.
