<p>A turbine driven rotary cutting tool is adapted for replaceable mounting on a tool holder that is part of for example a manual tool or a low speed machine tool such as a lathe, milling machine of drill head. The cutting tool has a one piece unitary cutting bit for performing a cutting operation and at least one bearing for supporting rotation of the cutting bit. At least a first part of the bearing is fitted integrally to the cutting bit so that replacement of the cutting tool includes replacing the cutting bit and bearing as a set. The cutting tool may perform various machining operations such as, for example, milling, drilling, deburring, polishing and grinding operations.</p> |
