Abstract
A boring tool comprises a body having, at a free end thereof, two insert holders which are radially adjustable by displacement relative to a groove defined by two opposing boundary surfaces and accommodating two elongate guide lugs on the insert holders. The groove merges, at opposite, parallel edges, into first support surfaces, which are each inclined relative to the tool axis, in a preferred embodiment in a rearward-outward direction from the edge so as to form an acute-angled wedge-shaped portion of material between each of the first support surfaces and a respective groove-defining surface. The support surfaces are each adapted to cooperate with similar, second support surfaces on the holders, the other support surfaces are similarly inclined, more specifically relative to boundary surfaces of the guide lugs, at substantially the same acute angle as the angle between cooperating surfaces of the wedge-shaped portions of the tool body.
