The invention discloses a tool bit for a pier rotating all-in-one machine. A blade mounting position is arranged on a blade mounting part at one end of a tool bar; a blade mounting slot with a triangular structure is formed between a first limiting bump and a second limiting bump on the tool bit mounting part; the blade is fixedly arranged between the first limiting bump and the second limiting bump through a blade fixing structure; and a cutting edge extends out from one side, away from the first limiting bump and the second limiting bump, of the blade mounting slot. The tool bit, with optimized design, for the pier rotating all-in-one machine is reasonable in structural structure; the blade and the blade mounting part are arranged, so that connecting firmness between the blade and the tool bar during use is guaranteed; the first limiting bump and the second limiting bump prevent the blade from shaking during use; the blade is made from a wear-resisting material, so that the service life of the tool bit is g
