<p>A tool holder having a head with four pockets, each for supporting an indexable insert. Each insert is mounted on the head such that it can be indexed to reposition a plurality of cutting edges on the insert. The head has a shank rotatably mounted in a body supported on a machine, such as a lathe. A handle connected to the shank is used to replace an insert in a cutting position with another insert merely by rotating the head and without repositioning the body.</p> |
