Cutting Enclosures: Rectangular Opening Tool?

[david90]

I have this box and I need to cut a rectangular opening to expose my led display. My question is there a tool to make a clean cut of the rectangular shape opening? I tried using a rotary but it is not a very smooth cut. Is there a way to do it using everyday tools?

I am not sure what a rotary is? I will assume it is an metal box.

You give no idea of the size of the hole, that can make a lot of difference. I have used nibblers to do this sort of job. IF the hole is large they can be pretty tedious. Also it requires a lot of file work to smooth it out.

A thin cutting disk on a dremal like tool (is this your rotary?) can do a very nice job if you have patience.

For larger holes, dill a start hole then use a fine toothed blade in a jig saw.

Yes, there are several tools that can be used to make a clean and precise rectangular opening in an enclosure. One option is to use a jigsaw with a fine-toothed blade. This tool allows for more control and precision compared to a rotary tool. Another option is to use a handheld router with a straight bit. This tool is commonly used for woodworking and can provide a clean and smooth cut. Alternatively, if you do not have access to power tools, you can use a hand saw and a file to carefully cut and shape the opening. Whichever tool you choose, it is important to take your time and make precise measurements before cutting to ensure a clean and accurate opening for your LED display.
