There is provided an improved scabbler bit wherein the bit is fixable to a piston of a scabbling machine through a male shank portion. The shank portion carries a circumferential groove for cooperation in the side wall of the piston to hold the shank firmly within the piston. There is also provided a scabbler bit wherein the shank portion is separate from the carrier. A novel design of a scabbler tip is also disclosed together with a novel arrangement of tips on the base of a tip carrier.
