Abstract

Handle tool for boring which is essentially characterized by presenting frontally, according to standardized angular measurements, a trapezoidal section recess inclined disposed with respect to the axis of the support handle, whose recess has double exit at its ends and is intended to contain, with possibility of longitudinal displacement, to the hard metal insert of the case also provided with a trapezoidal section, with which it is transversally immovable in all directions, reaching, on the other hand, the depth of the recess up to approximately half of the body of the support, and with the peculiarity that such a recess is also affected, in all its depth, by a base of metal harder than that of the handle itself, while its internal flank contains the mouth of an oblong and oblong hollow with respect to its position, being the parallel walls of such a hole perpendicular to its bottom, while the wall opposite the opening ra is conical truncated downward, exceeding the depth of the hollow to the base of the container recess of the tool, and being the same intended to contain a wedge of exactly the same configuration but less than the depth of the hole, so that once the wedge is inserted in it and it is requested inwards by a screw that screws in its body with entry under the handle, the wall, also conical, resting in the mouth next to the recess, imprisons strongly the insert inside it immobilizing it in the longitudinal direction in conditions to carry out the machining of the case, being also provided the clamping wall of the wedge, for greater effectiveness of the fixation, of a flute perpendicular to the base of the recess, while the wall corresponding side of the insert where the reference flute is applied, is covered in each case by a layer of soft soldered material gives to the same facilitating the best grip of both elements.
