    Self-Centering Stud-Driven Round Hole Punches

    Make accurate holes every time. Drill a pilot hole into your workpiece—the center of these punches fits inside the pilot hole to keep cuts aligned. The pilot hole should be slightly larger than the size of the stud. The die’s design splits the punched out plug in two for easy removal. All punches require a hydraulic driver. They are also known as knockout and chassis punches.
