Abstract

A rotary cutting tool for enlarging existing holes has a shank/body portion 30 for rotation relative to a workpiece and a cutter 34 secured releasably and non-rotationally relative to that end portion of the shank which, in use, is remote from the tool holder. The cutter can be made of relatively expensive material such as high speed steel or tungsten carbide and the shank of cheaper material such as structural steel, thus reducing manufacturing costs. The shank may be significantly smaller in cross-section than the diameter of hole produced by the cutter, reducing friction between shank and hole and enhancing coolant flow rates. The shank may have clip cleaving flutes 33 as well as the cutter, and also coolant flow passages 36-39. <IMAGE>
