Abstract
A boring tool to produce wells from 0.40 to 1 m diameter to a depth of up to 5 m in soil of any composition for columns or piles, consists of a cylinder with a closed top which can slide axially on a splined or polygonal vertical drive shaft. Two hydraulic cylinders perform the axial movement. The bottom edge of the cylinder is armed with cutter picks or abrasive blocks. The tool is not limited to soft soil and can deal with rocky ground. Irregular ground structure cannot deflect the tool which is easily centered by a point at the drive shaft end. The core need not be broken up so that the advance rate is greater. Power cylinders can be used to move the cylinder axially on the drive shaft. A drill point at the forward end of the revolving drive shaft helps to centre the tool during penetration in the ground.
