Augers are used for loosening and conveying dry ground or rock. For drilling in dry ground, LEFFER offers a wide range for dry drilling variants for optimal processing of the subsoil: 

The number of cutting edges, the pitch of the auger helix and the type and number of teeth or bits vary depending on the soil conditions. For better guidance of the auger, the augers are additionally equipped with calibration bits. Wear strips reduce the abrasion on tooth holders and auger flights. We recommend our types BS and BS-1 for soft soil layers and BSF, BSFoP, BSP and BSP-2 for hard soil layers.
