A reaming tool in the form of reamer shoe (10) is adapted for location in a wellbore and comprises a substantially tubular mandrel or body (12) having a central bore (14) located about an axis (15). A cap or nose (16) is coupled to a distal end portion of the body (12) via a connection (18). The nose (16) defines an eccentric offset portion or lobe (20) which extends to a greater axial extent than the remainder of the nose (16). A weighting arrangement is provided, the arrangement adapted to balance the mass of the nose about a central axis of the shoe. The distal surface of the nose (16) comprises a substantially concave central portion (17). The nose (16) further comprises a projection or dimple (19) on an opposing side of the nose (16) from the concave surface.
