A cutting assembly suitable for use on a drillable drill bit is described. The cutting assembly comprises one or more cutting members comprising one or more pre-formed pockets and one or more cutters located with the pre-formed pockets. A detachment facilitating feature is located at the interface between the cutting members and the cutters. The cutters of the drill bit are therefore mechanically robust for normal drilling operations but also facilitate detachment during a subsequent drill out procedure of the drill bit. |
