Punches & Knockout Punch Sets

Punches & Knockout Punch Sets help you mark, align, and create clean, accurate holes in metal, wood, and plastics with speed and control. From starting a precise drill point to driving out pins or cutting conduit-sized openings in electrical panels, these tools raise the quality of your fabrication and installation work while saving time.

General-purpose punch sets include:
- Center and automatic center punches for crisp starting marks that prevent drill bit wandering.
- Pin and drift punches for installing and removing roll pins, dowels, and bolts without damaging surrounding material.
- Nail sets for setting finish nails below the surface.
- Transfer punches for copying hole locations with exact alignment.

Knockout punch sets (often called chassis or electrical knockout punches) produce smooth, perfectly round holes in sheet metal and stainless where hole saws might chatter or leave burrs. Choose manual draw-stud systems for compact field work or hydraulic and battery-assisted drivers for frequent, larger-diameter holes. Common conduit sizes range from 1/2 in. to 4 in., with metric options available.

Key benefits include clean edges, consistent sizing, reduced distortion, and faster workflow—ideal for electricians, HVAC techs, mechanics, and metalworkers. Look for hardened alloy or S2 tool steel construction, clearly stamped sizes, knurled or cushioned grips, and organized storage cases. For knockout punches, check material capacity (steel gauge and stainless rating), slug-splitting designs for easy removal, and compatibility with standard draw stud sizes and ratchets or hydraulic rams.

Tips for best results:
- Mark centers before drilling; use light oil on draw studs and dies.
- Support workpieces, align punches squarely, and avoid exceeding rated thickness.
- Dress mushroomed punch heads and keep tips sharp for clean marks.
- Store punches in a roll or case to prevent damage and mix-ups.

Whether you need a compact punch kit for service calls or a hydraulic knockout set for shop production, the right selection will deliver precise holes, fewer rework steps, and a professional finish.
