A drill bit comprises a shank mem- ber (31), a bit body (32) provided with cut- ters (33) and flexible material (35) between the shank (31) and the bit body (32) al- lowing relative tilting movement therebe- tween to reduce adverse effects caused by vibration of the bit. In other embodiments, flexible material is provided between the bit body and the cutters. In further embod- iments, the flexible material may be pro- vided in a tiltable sub-assembly for incor- poration in a drill-string above the drill bit. An apparatus for simulating drilling condi- tions is also provided.

L'invention concerne un outil de forage comprenant une tige (31), un corps d'outil (32) muni de lames (33) ainsi qu'un matériau flexible (35) placé entre la tige (31) et le corps de l'outil (32), permettant un mouvement de basculement de ladite tige par rapport audit corps afin de réduire les effets indésirables résultant de la vibration de l'outil. Selon d'autres modes de réalisation, le matériau flexible peut être placé dans un sous-ensemble apte à basculer, destiné à être intégré dans une garniture de forage au -dessus de l'outil de forage. On décrit également un appareil destiné à simuler les conditions de forage.
