| 1. An indexable tool comprising:
a handle;
an indexable body rotationally coupled to the handle; and
a splined coupling arrangement for coupling the handle to the body, the splined coupling arrangement comprising a push button,
a splined cylinder arrangement mounted on the push button, a retainer received within the push button and a fastener passed
through a longitudinal bore of the retainer and threaded into a longitudinal hole formed in the push button for fixedly coupling
and preventing relative sliding movement of the push button, the splined cylinder arrangement and the retainer,
wherein a series of splines on the splined cylinder arrangement engage the handle and the body when the splined cylinder arrangement
is in a locked position thereby keeping the handle fixed relative to the body, and
wherein displacement of the push button causes displacement of the splined cylinder arrangement into an unlocked position
that causes a series of splines to disengage the handle and the body thereby allowing the handle to change a rotary position
relative to the body.
