The invention discloses a boring tool used for machining a small-hole-diameter step type round hole inner cavity and provided with a replaceable tool head. The technical problems that when an inner hole inner cavity provided with a step is subjected to high-speed boring machining, the machining concentricity is prone to deviating, and the machining efficiency is low are solved. A tool rod (1) is provided with a barrel-shaped cavity (3), and a cavity opening (4) of the barrel-shaped cavity (3) is connected with a tool head seat (2). The boring tool is characterized in that the tool head seat (2) is provided with a tool head and tool rod connection thread (6) and an annular positioning step (9), and the tool head seat (2) and the tool head and tool rod connection thread (6) are connected into the cavity opening (4); the axis (10) of the annular positioning step (9) coincides with the axis (11) of the tool rod (1); and a tool blade (7) is fixed to the tool head seat (2) through a jackscrew (8). The machining efficiency and the machining quality are greatly improved.
