Abstract
A one-piece lathe tool for boring with a cross-section of less than 10 mm, includes an essentially-cylindrical tool body intended to be inserted and held in a tool support which is traversed by at least one lubricant supply channel. One end of the tool body extends into a neck which terminates in a head that forms the active part of the tool. In order to ensure good lubrication, the neck is offset in relation to the axis of the tool body, while, at the end of the neck, the head is offset in relation to the axis. The head, together with the cutting edge thereof, falls within and is essentially tangent to the periphery of a cylindrical space corresponding to the extension of the tool body. A machining assembly including such a one-piece lathe tool and a tool support are also disclosed.

Lathe tool of the single piece type for boring with a cross-section less than 10 mm, comprising a substantially cylindrical tool body (2) provided to be engaged and held in a tool support (10) traversed by at least one lubricant supply channel, this tool body (2) being prolonged, at one end (3), by a neck (4) terminating in a head (5) comprising a cutting edge (6) and constituting the active portion of the tool (1), characterized by the fact that the neck (4) is eccentric relative to the axis of the tool body (2), whilst the head (5), at the end of this neck (4), being itself eccentric relative to this axis, said head (5), with its cutting edge (6), being inscribed in and substantially tangent to a periphery (8) of a cylindrical space (7) corresponding to the prolongation of said tool body (2).
Machining assembly comprising a lathe tool (1) of the single piece type for boring with a cross-section less than 10 mm and a tool support (10) comprising, at one forward end (11), a recess (12) suitable for the reception of the body (2) of the lathe tool (1), as well as gripping means (13) for holding this latter in said recess (12), this tool support (10) being also traversed by at least one lubricant supply channel (14), characterized by the fact that said channel (14) opens at the forward end (11) of the tool support (10) at the periphery of the recess (12) for reception of the tool body (2) which is prolonged by a neck (4) eccentric to the axis of this tool body and terminating in a head (5) comprising a cutting edge (6) constituting the active portion of the tool (1), this head (5) being itself eccentric to this axis, said head (5), with its cutting edge (6), being inscribed in and substantially tangent to the periphery (8) of a cylindrical space (7) corresponding to the prolongation of said tool body (2).
