Application

The drilling Augers have been designed for srilling in dry soil and in rock. Various teeth type are avaliable for different soil condition. The geometry of the teeth arrangement is optimized for reaching excellent cutting performance. For large drilling diameters or for the use in uncased piles augers with double start head are recommended.

Feature

Conical Auger location by pilot,conical structure drilling into the rock.Straight Auger design as straight type, better for carry soil.Double cutter bearing unniform force,can avoid inclined hole, and easy to carry soil. Single cuttter is easy to dump spoil for cohensive soil.
