A cutting device (11) comprises a cutting head (14) of substantially circular cross-section, the cutting head having a main axis (X), and a distal cutting edge (23). The cutting edge has a first cutter. The cutting head (14) has a cutting portion (21) and a second cutter extending inwardly of the cutting portion. The second cutter (26) comprises a plurality of spaced cutting members (32) arranged in an array around the main axis. Each cutting member has a substantially planar cutting surface (32A) extending substantially parallel to, and offset from, the main axis.
