coupling an impact portion of an attachment to a powered hammer, the powered hammer including a first handle, a second handle, and a set of actuators coupled to at least one of the first handle and the second handle;
positioning the rod between a first jaw of the attachment and a second jaw of the attachment;
activating a first motor via the set of actuators to move the first jaw toward the second jaw, such that the rod is clamped between the first and second jaws; and
activating a second motor via the set of actuators to drive an axial impact mechanism of the powered hammer to deliver repeated axial impacts to the impact portion of the attachment.
