The tool 10 for finishing a hole (2, Figure 4) in a work piece (1, Figure 4) includes a neck portion 16 having an axial length and a first portion 14 and a second portion 18 disposed either side of the neck portion. The first and second portions have first and second inclined finishing portions, 22 and 26 respectively, inclined inwardly towards the neck portion in opposing directions. The tool is arranged such that it can be disposed within the hole and simultaneously rotated and moved in a circular path so as to finish an edge of the hole with one of the finishing portions. The inclined portions may include at least part of a frusto-conical finishing surface. The tool may also include helical swarf passageways (28, Figure 3). The tool may be a deburring tool and may be used for finishing a blind hole in addition. |
