Abstract

A controllable percussion tool for drilling holes in the soil comprises a hollow cylindrical housing with a tapered front end, an anvil having a striking surface inside the housing and a boring surface outside the housing and a cylindrical nose portion with a slanted face, a reciprocally movable hammer in the housing, and guide fins positioned on the exterior of the rear end of the housing. The fins are movable between two positions which permit non-rotative movement through the soil and rotation of the housing as it moves through the soil. A control system for guiding the tool in a borehole includes an axial electromagnetic source for generating an axial alternating magnetic field. A sensing assembly includes pick up coils for sensing the magnetic field.
