To cut a square hole in wood using this method you’ll need to follow these steps:
Step 1: Measure and Mark the Hole
First, you’ll need to measure and mark the square hole. This can be done using a measuring tape, pencil, and framing square.
If possible use the backside of the piece of wood you’re working on to mark up your template. Make sure to mark clearly with thick lines and take some time making precise measurements to get the best results. This will help in avoiding mistakes and wasting time and effort correcting them later.
Step 2: Create and Drill the Pilot Hole
Once you’ve marked your hole, use a drill to make it in the center of the square. This will serve as the starting point for your jigsaw. The hole should be big enough to fit the blade through it without much resistance. Be careful and make sure not to drill the hole in a location that will cause you to go outside the marked line.
Step 3: Cut the Square Out
Not that you’ve paved the way for your jigsaw, it’s time to take it out and start cutting. Apply little pressure on the jigsaw by gently pushing it towards the hole. Once you have the start point established, slowly move the blade, carefully tracing your marked line.
Do not force the blade but exert just enough pressure to cut through the wood. Do not move too fast or you might get off track and ruin your work.
Make sure to cut to the inside of the line since if the square is a bit small, you may widen it using sandpaper, a file, or an oscillating tool. On the other hand, if you cut near the outside you risk the chance of the actual hole being too big for your intended purpose.
Cutting a square hole in the wood with a jigsaw is pretty simple and you shouldn’t encounter any issues if you follow the steps outlined. If there are some problems, it is most likely due to inadequate marking and inaccurate measurements.
If you make a mistake and go off course, do not try to overcorrect it instantly with the jigsaw. Instead, stop cutting and cautiously remove the tool, think and plan before you make any decisions.
Generally, by carefully re-aligning your cuts, you can fix most mistakes and get on track with your task. Even if not, cutting through with the jigsaw is a pretty quick process, so you can always start over with a new piece of wood.
Step 4: Clean Up Your Work
Now that you’ve cut the square out of your wood, clean it up with sandpaper or a file. You’ll need to smooth out the edges and remove any chipped-off wood fibers. This will ensure a clean finish for your work.
Start with low-grade sandpaper such as 100-grit sandpaper and make sure to apply the same amount of pressure all over for consistent results. Check if you’re fully satisfied with the size of the cut. Then, follow up with a 120- or 180-grit sandpaper if you wish for an even more refined look, but you won’t necessarily need it since 100-grit sandpaper is quite reliable and efficient in getting the job done. Just keep at it until you’re happy with the results.
How to Cut a Square Hole in Wood Without a Jigsaw
If you don’t have a jigsaw or simply do not wish to use one, there are several alternative tools and methods for this task. We’ll tell you 4 other ways of getting the job done and help you achieve a clean-looking square hole.
Using a Drill and Saw
This method requires a bit more effort but works just as fine. Start by using a drill to bore the pilot hole into the wood. Then switch over to a saw of your choice and cut out around the pilot hole. You may either use a hand saw or a circular saw, depending on your preference or what you have available.
When using a saw, you may have to reposition it several times so the saw’s teeth don’t pop out of the marked margin of the square hole. It is a bit of a time-consuming process, but it does eliminate the need for a jigsaw.
Using a Chisel
This technique or tool is recommended for smaller and more delicate pieces of wood projects. A chisel offers more control and allows for greater accuracy compared to a circular saw or jigsaw.
Start by cutting out the corners of the square hole. Set the chisel’s tip on a corner of the square you’ve drawn then tap a sledgehammer on the chisel to cut away at the wood. Tap continuously until the knife cuts through the entire thickness of the wood. Repeat the above procedure for each corner until you get a cutout.
Using a Router
Routers offer stability and ease of use for this task but again isn’t as fast as a jigsaw. Though perhaps It is the best alternative for cutting perfect square holes in wood since it can be set to cut exact depth and width. This process may seem a bit complicated and difficult for a beginner, but it isn’t nearly as hard as you’d expect.
To begin with, create a template with the template guide and router bits, then use the square dimensions to plan out the design. Add the same number of segments on each side of the template. Next, In one corner of the square on the wood sheet, drill a pilot hole to establish the starting point for your cut. Using the pilot hole, position the router fence correctly then use the router to cut out the square hole. Cutting one line and then repositioning and cutting the next is a quick and efficient way to get done with this task.

Using an Angle Grinder
An angle grinder is a highly powerful tool for cutting through layers of material with ease, but using this tool for woodworking is highly dangerous. We recommend you rather opt for a jigsaw, circular saw, or router than choose to use this tool. It has an exposed blade with no spring back guard and is used free-handed as it lacks a soleplate that could otherwise provide stability.
Use at your own risk!
Before you start using the angle grinder, replace the actual disk with the sawing disc that has fine teeth, make sure that the spin direction on both the blade and the machine is pointing in the same direction, and check that the blade is securely tightened.
Determine the required square hole area and mark it. Use a vise to secure the wood piece. Now, proceed with your cut. Start the angle grinder, once it’s spinning at the desired speed begin cutting along the markings by moving it on the drawn lines.
