A drill bit assembly for drilling a hole through earth, the drill bit comprising: a bit body extending between a first end and a second end along a longitudinal axis of the bit body with a connecting arrangement positioned at the first end of the bit body for coupling the bit body to a rotating shaft for providing rotational torque to the bit body; a cutting head including a leading tip portion for cutting into earth and a trailing receiving portion for receiving the second end of the bit body in an internal cavity defined by the receiving portion to allow the cutting head to be removably coupled to the second end of the bit body; a retaining arrangement to retain the second end of the bit body in the receiving portion of the cutting tip.

Drill bit for boring earth and other hard materials

The present disclosure relates to coupler for connecting a drill pipe to a drill bit as well as methods for manufacturing the same. In particular, the present disclosure describes a coupler which includes a housing including a first connecting portion at a first end for connecting to a drill pipe, a base coupled to the housing and including a second connecting portion at a second end for connecting to a drill bit, and an intermediate component disposed between the base and the housing, wherein the coupler is configured for rotation about an axis during use, with the intermediate component allowing limited relative rotation between the housing and the base about the axis.

Drill coupler for mitigating torsional vibration

The present disclosure provides a cutting head adapted to removably couple to a bit body of a drill bit assembly. The cutting head includes a leading cutting tip for cutting into earth and a trailing receiving portion for receiving a second end of the bit body in an internal cavity defined by the trailing receiving portion to allow the cutting head to be removably coupled to the second end of the bit body.
