When to use: 

Wood Router is specially designed to cut thicker wooden sheets. So, working on a thick wooden sheet router can save you a lot of time and effort.

How to use router to make square hole in wood

the first step will be to make a square template. Make sure to be precise because the template will determine how clean the square will be, use a square dimension to construct a layout for this template. Add 0.35 inch to each line of the square template.

Before you start working, make sure there’s nothing that can distract you; distraction can lead to messy work.

Next, drill a hole on one of the corners and align the router with the square you are planning to cut. Now, it’s time to switch the router and let it cut along one of the lines. When it cuts one line, make sure to pause the router and rotate the wooden sheet to cut through another line.

Repeat this method to all of the lines to get a clean square hole.

Finishing touches:

After you have successfully cut a hole on your wood, it’s time to clean up the inner edges because a wood router will give you rounded edges to make the edges sharp; you will need the help of sandpapers. Take low grit sandpaper and start sanding the edges. Make sure not to be too hard while sanding, you may ruin the shape or size.
