An indexable tool includes a handle having a first prong formed with a first splined orifice and a second prong formed with a second splined orifice. An indexable body has a third splined orifice aligned with the first and second splined orifices. A splined coupling arrangement rotatably joins and selectively locks and unlocks the handle and the indexable body together. The coupling arrangement includes a push button, first and second adjacently disposed inserts, a retainer, a cap and a spring. In a locked position, the spring is biased to hold external splines of the first and second serrated inserts in common engagement with the first, second and third splined orifices to prevent relative rotation between the indexable body and the handle. In an unlocked position, the push button is pushed against the bias of the spring to move external splines of the first serrated insert into exclusive engagement with the third splined orifice of the indexable body, and to move the external splines of the second serrated insert into engagement with the splined orifice of the second prong enabling rotary adjustment of the indexable body relative to the handle and about the cylinder.
