Claim:
A tool body for a rotatable cutting tool, the tool body comprising at least one recess for receiving a replaceable insert, the recess including first and second opposing walls; the body further including an isolating channel spaced from the recess to define an elastically deformable leaf therebetween, wherein the first wall of the recess is formed by the leaf; wherein the isolating channel is inclined at a first shallow angle to approach the recess in a direction away from an open end of the isolating channel; a leaf-bending element adjustable within the isolating channel for elastically bending the leaf from a relaxed position to a clamping position wherein the first wall clamps the insert against the second wall; the first wall being inclined at a second shallow angle relative to the second wall when the leaf is in the relaxed position wherein the first wall diverges from the second wall in a direction away from an open end of the recess.
