    Compact Portable Lever-Operated Hole Punch Sets

    Image of Product. Front orientation. Hole Punches. Compact Portable Lever-Operated Hole Punch Sets.
    About half the size of a standard portable lever-operated punch, these punches can fit in your toolbox. The lever handle provides extra punching force to quickly punch through metal. The punches have an adjustable throat to reach varying depths from the edge of your material. Switch out the included punch and die to create holes of different sizes.
    Note: As your punch size increases, the thickness of steel these tools can cut decreases.

    Flared Hole

    Create flares around already-cut holes in sheet metal up to 3/16" thick to make the edges stronger and more rigid. Also known as dimple dies. Press a male and female die together using a hydraulic press. When you don’t have access to a hydraulic press or your material won’t fit in a press, bolt the dies together. For making multiple flares quickly, use a hydraulic knockout punch driver. Dies are made of hardened steel for strength and durability.

    Self-Centering Stud-Driven Hole Punch Sets

    Image of Product. Front orientation. Hole Punches. Self-Centering Stud-Driven Hole Punch Sets.
    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. Pilot holes should be slightly larger than the size of the stud. The die’s design splits the punched out plug in two for easy removal. Use these punches with any 8- or 11-ton hydraulic driver. They are also known as knockout and chassis punches.
