This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.

A cover assembly for use on a cut-off tool. The tool has a housing, a motor having a rotor, and an output shaft for fastening a cutting wheel. The shaft is connected to the rotor, so the output shaft turns about an axis aligned with the centerline of the rotor. The assembly includes a cover sized for receiving the cutting wheel. The cover has a collar sized for receiving a portion of the tool surrounding the output shaft. The collar is fastenable to the tool. The tool includes a foot having an elongated planar sole pivotally attached to the cover. The foot is pivotable with respect to the cover to adjust a distance that the cutting wheel extends from the sole. The cover includes a clamp for clamping the foot to the cover when the distance the cutting wheel extends from the sole corresponds to a desired maximum cutting depth.
