This invention relates to honing tools, and par
ticularly to a new and novel honing tool of the
single stone type.
The present honing tool comprises a tubular
body having a rotatable rod therein provided
with a cam surface which engages the carrier for
the stone for moving the stone outwardly of the
axis of the body. As one means for rotating the
cam, an axially movable element is mounted
within the tube having engagement with the ro
tatable cam member for turning the member
when the element is moved axially. The axially
movable member is provided with a head which
engages an adjusting element of a honing ma

the carrier against the cylinder bore occurs on

prevents chatter because of the three-point con

may occur to the carrier at these points will be
