Hollow Stem Auger Drilling Rods Drill Pipe Geological Drilling Tools High Bending Strength
Hollow Stem Auger Drill Rods Drill Pipe for Geological Drilling
Geological spiral drill pipe
Material:
The geological auger shaft is made of high quality geological special alloy steel pipe, and the drill pipe joint is made of high quality alloy structural steel.
Features:
1. The drill pipe has the characteristics of high bending strength and firm welding;
2. Features of high production efficiency and stable quality
3. The ultra-low spiral spiral blade design makes the geological auger drill rod have large torque, fast slag discharge, good drilling formation and difficult to drill.
