– The spiral blades and vertical cutting blades are made of carbon steel equivalent to S45C, and undergo heat treatment including hardening (increases strength and wear resistance) and tempering (increases elasticity).
– A hole approximately 15 cm deep can be dug in one operation. By repeating the process several times, a depth of approximately 60 cm can be achieved.
　*This depth is an estimate. It will vary depending on the soil type and other soil conditions.
– The “pressing plate” compresses the soil and holds it firmly.
– The “two (double) spiral blades” allow for digging into the soil, increasing work efficiency.
– The “two vertical cutting blades” scrape the walls of the hole, making it easier to pull up, especially in clayey soil.
– Excavating pilot holes for poles and stakes. – Setting up tree supports, fertilizing, and planting trees.
– Installing fences, railings, and nets.
– Hole diameter: 60mm.
