Knockouts
Knockout Tools for Panel Work and Conduit Entry
Knockout tools are purpose-built devices used to punch clean holes in electrical panels, junction boxes, and enclosures for conduit entry, switches, and other hardware. These tools help create precise openings without cracking or deforming the surrounding metal, making them essential for electrical installers, panel builders, and maintenance technicians.
Galco offers a range of knockout solutions to match your application needs. Choose from heavy-duty industrial punch tools for frequent or high-volume panel work, versatile knockout drivers that adapt to standard punch sizes, and specialty punch tools for unique enclosure configurations and fitting challenges.
Knockout tools are typically used with a hammer or mallet to drive the punch through sheet metal, producing a smooth, round opening ready for conduit fittings or cable glands. Many knockout sets include adapters and dies that match common electrical box and enclosure sizes, simplifying repetitive work and improving productivity.

Frequently Asked Questions
What is the difference between industrial punch tools and knockout drivers?
Industrial punch tools are designed for repeated, heavy-duty use and are commonly used in panel shops and high-volume installations. Knockout drivers provide the driving force that pulls the punch through the metal and are often used with interchangeable punch and die sets.
How do knockout tools compare to drilling for conduit entry?
Knockout tools produce smoother, more consistent holes than drilling and reduce the risk of burrs, sharp edges, or enclosure deformation. This improves fit for conduit fittings and helps maintain electrical safety and professional finish standards.
What factors should be considered when selecting knockout tools?
Selection depends on panel material thickness, hole size requirements, frequency of use, and available working space. Choosing the correct punch size and driver ensures clean cuts, faster installation, and reduced wear on tools and enclosures.
