Abstract

A drill bit (1) comprising a body which is rotatable, in use, about a body axis (18) for drilling, and a cutting element (10) comprising a superhard portion (4) with an end face (2) and a peripheral cutting face (5), the cutting element being secured to the drill body so as to be moveable in a direction of movement when the drill bit is rotates, the cutting element further being rotatable about a cutting element axis (7) thereof, the cutting element axis extending away from the end face of the superhard portion through the cutting element, and wherein the cutting element axis is tilted towards the direction of movement (A).
