The present invention provides a burr 13 in the form of a generally cylindrical rod, the burr 13 having a proximal end 14 for mounting in a tool for rotating the burr and a distal cutting end 15, the burr having a cutting portion 17a, 17b defined by a portion of a surface of the burr which comprises a plurality of teeth 16, the cutting portion 17a, 17b including and extending from the distal end 15 back towards the proximal end 14, the burr being characterised in the cutting portion 17a, 17b comprising a cylindrical portion 17b of a first diameter and a distal end portion 17a having a second diameter greater than the first diameter. The burr 13 is particularly suited to the drilling of cylinder locks.
