Abstract
A boring tool is equipped with a radially adjustable clutter element, and a remotely-operated mechanism for adjusting the cutter element between its active and inactive positions. During movement of the tool into a hole in a work piece the adjustable cutter element is inactive; the cutting operation is performed by one or more non-adjustable cutter elements. When the tool holder reaches the limit of its penetration into the work piece the remote adjusting mechanism is operated to move the adjustable cutter element radially outwardly to an active cutting position. During return movement of the holder out of the work piece the adjustable cutter element performs a finish machining operation on the hole surface.
