<p>A rotatable cutting tool has a shank portion for coupling to a tool driving device and a cutting portion in which are retained plural replaceable cutting inserts, each insert having at least one cutting edge. The shank portion includes a mounting face for removeably supporting an insert mounting disk having plural recesses at the periphery thereof for receiving the replaceable inserts. Each recess provides at least one seating surface for an insert, and includes opposing face portions between which an insert is releasably retained. The disk includes a central bore and radial grooves, at least one radial groove connecting the central bore and each insert receiving recess. The disk includes a concave central portion surrounding the central bore. A clamping means secures the disk to the shank and is used to elastically deform the concavity of the disk, whereby clamping forces are built and relaxed on all inserts placed in the disk concurrently by adjustment of the clamping means.</p> |
