This W Spiral Hole Digger with hole/head diameter of 75 mm. Ideal for poles and piles hole digging, tree the poles support, fertilization, and tree planting. It can dig a hole with a diameter of 60 mm and in-depth of about 150 mm in one operation and 600 mm in-depth by repeating several times.  

Carbon steel S45C equivalent is used for spiral blades and vertical cutting blades, heat treatment quenching (increases strength and wear resistance), and tempering (increases elasticity). The "Pressing Plate" presses the soil tightly and holds it firmly. Two (double) spiral blades can dig into the soil and work more efficiently. Used two vertical cutting blades to scrape the wall surface of the hole, making it easy to pull up, especially for clay soil.
