Abstract

PURPOSE:To aim at reduction of labor and cost in a surface preparing operation by arranging a support base and a hammer drill in such a way that a pipe and a bit are coaxially opposed to each other, and making the support base and the hammer drill movable along the axial direction of the pipe. CONSTITUTION:In a supporting frame 1 are provided a support base 2 for supporting and fixing a pipe A and a hammer drill 4 for attaching a bit 3 used in surface preparation of the inside of the cylinder A. Thereat, in the bit 3, the tip of a circular shaft portion 32 leading to a shank 31 is formed into a bifurcated shape, and then, a spiral groove 34 is provided and tips 35 are fixed at the tip thereof. Further, a change mechanism is disposed in the hammer drill 4, and thereat, the rotation of a motor 36 is changed over, via a wire 37, into a hammer drill operation, which exerts the compound action of a drilling action and a hammering action by the effect of reciprocating motion onto the bit 3, and a hammer operation, which exerts only the reciprocating motion onto the bit 3. Therefore, it is possible to aim at reduction of cost in surface preparing operation.
