The invention discloses a shiftable rough boring tool with bidirectional machining capability. The shiftable rough boring tool with the bidirectional machining capability comprises a boring tool body, an adjusting push rod, at least one pendulum boring tool rod and at least one boring tool blade, wherein the boring tool body is a circular rod; an inner hole is formed in an end surface of one end of the boring tool body and leads to the end part of the other end of the boring tool body along a central axis; the adjusting push rod is arranged in the inner hole of the boring tool body in a matched manner, can move along the axis direction in the inner hole and can be fixed; middle sections of the pendulum boring tool rods are pivotally connected to a peripheral wall of the boring tool body; one end of each pendulum boring tool rod is hinged to the front end of the adjusting push rod; a blade mounting part is arranged at the other end of each pendulum boring tool rod; and each boring tool blade is fixed in the blade mounting part at the other end of the corresponding pendulum boring tool rod. By the structure of the shiftable rough boring tool, a machining function under multiple working conditions including different hole depths, apertures and hole patterns can be fulfilled in a boring process.
