Product Information
Full details
The VEVOR Knockout Punch Set is an essential tool for electrical contractors and industrial technicians who require precise, burr-free holes in metal cabinets and switchgear. This 15-ton hydraulic kit streamlines the installation of conduits and fittings by providing significant power in a compact package. While it offers immense force for heavy-duty materials, users should note that the manual hydraulic operation requires deliberate setup and physical space for the cylinder to function effectively during large-scale projects.

FAQs
What is the maximum hole size this tool can punch?
The kit includes dies to create holes up to 4 inches in diameter.
Can I use this on stainless steel?
While it is designed for standard electrical cabinet metals, ensure the steel thickness is within the specified tolerances for 15-ton hydraulic tools.
How do I maintain the hydraulic pump?
Keep the unit clean, avoid storing it in wet environments, and periodically inspect the hydraulic seals for any signs of wear.
Is a pilot hole necessary?
Yes, a pilot hole is required to insert the draw stud before the punching process can begin.
What should I do if the cylinder leaks oil?
Stop operation immediately and inspect the seals; if they are damaged, they will need to be replaced by a professional to ensure safety.
Troubleshooting
Punch fails to penetrate the metal
Check if the hydraulic valve is fully closed and verify that the material thickness is within the tool's rated capacity.
Hydraulic handle feels loose or unresponsive
Ensure there is no air in the hydraulic system and check for leaks at the hose connection points.
Dies are difficult to thread onto the draw stud
Clean the threads on both the die and the stud with a wire brush to remove any metal shavings or debris.
Pros and Cons
Pros
- High 15-ton output for clean hole production
- Comprehensive 10-die set covers all standard electrical conduit sizes
- Compact and portable design for field use
- Reduces manual labor compared to hand-crank or drilling methods
Cons
- Requires manual hydraulic operation which can be labor intensive
- Heavy weight due to the solid steel construction
- Requires clear clearance behind the panel to fit the hydraulic ram
Setup, Compatibility & Care
To operate, first drill an appropriate pilot hole to accommodate the draw stud. Select the correct die size, thread the stud through the hydraulic cylinder, and secure the punch on the opposite side of the metal panel. Ensure the hydraulic valve is tightly closed before pumping the handle. For care, keep the hydraulic cylinder free of metal filings and grit, which can damage internal seals. Store all dies in the designated slots within the toolbox to prevent thread damage. Periodically check the hydraulic fluid levels and ensure the pump mechanism is operating smoothly.
