Construction Machinery Tools Drilling Bucket Drilling Auger Bullet Teeth
An auger is a drilling device, or drill bit, that usually includes a rotating helical screw blade called a "flighting" to act as a screw conveyor to remove the drilled out material. The rotation of the blade causes the material to move out of the hole being drilled.
In construction, augers are used for special drilling rigs to dig holes for deep foundation piles. Another use is for piles forming a piling retaining wall, which can be constructed in the same way as foundation piles.
There is two types of conical Auger single and double cut auger,they are applicable for drilling in medium to strong rock (15~60MPa) with drilling Diameter Range: 600~3000mm,while double Cut Augers are recommended for bigger diameters uncased boreholes.
The conical augers have been designed for drilling in dry soil and in rock,it can be used for weak rock(<5Mpa).various teeth configurations are available for different soil conditions.The geometry of the teeth arrangement is optimized for reaching excellent cutting performance.
The diameter series of augers match with the casing tubes and other lengths and diameters can be supplied on request.
1. High quality material
2. Guaranteed welding process(full welding)
3. Optimized teeth angle
4. Specialized teeth arrangement
5. Movable pilot holder(easy to replace teeth)
6. Conical body (protect drilling buckets from getting stuck )
1. Very weak rock(<5Mpa).
2. Double cut auger is recommended in uncased bores or for bigger diameters and secant pile walls.
