A tooth for attachment to the lip of a bucket of a working machine via an adaptor, having a cavity for receiving a portion of the adaptor, the cavity extending between first and second opposed outer working surfaces (12, 14) from an open end (104) to a bottom end (105); the cavity (103) delimited by an inner wall (102) having first and second facing inner walls (106, 107), and opposing side walls (108), interconnecting the first and second inner walls (106, 107). The cavity defines a back portion (BP) along the Y axis and between the plane spanned by the X and Z axes and the open end of the cavity, a front portion (FP) along the Y axis and between the plane spanned by the X and Z axes and the bottom end of the cavity; and a stepped portion (SP), interconnecting the back portion and the front portion. |
