Flights increase diameter gradually as a spiral and round shank chisels are placed along the borderline up to the cutting edge. So that rock formation can be ripped progressively with excellent results All augers have central pipe diameter and thickness together with flights pitch and thickness designed accordingly with XP rotary torque and gravel compressive strength. All flights thickness are provided with special wear protection HB 600/900.
They can be supplied with different type of Teeth and Round Shank Chisel accordingly with soil and rock hardness. Not only, their number and inclination are obtained trough a special software capable to guarantee high productivity.
