How To Cut A Square Hole In Wood (3 Ultimate DIY Ideas)

How To Create A Square Hole In Wood?

Have you ever asked how to cut a square hole in wood, including a flat plywood piece? There are various approaches you may take to do this work, or to be more accurate, a few specific tools. The most common method is using a jigsaw; however, a manual saw and chisel are also practical to do this task.

Let’s take a look through these three DIY methods that are easiest, cleanest, and quickest for cutting a square hole in wood.

3 Techniques To Cut A Square Hole In Wood

Thankfully, drilling a square hole in wood is a relatively simple job that anybody with a basic understanding of carpentry and the appropriate equipment can learn quickly.

1. Using a jigsaw (most common)

A Jigsaw

A jigsaw is among the ideal tools for cutting a square hole into a wood piece. It is a portable power saw with a relatively narrow reciprocating blade that travels up and down at high-speed rates. 

Jigsaw puzzles are ideal for this and many other related tasks. Let’s look at how to cut a hole in the middle in wood using a jigsaw.

Step 1: Measure

The first challenge is to select the wood piece you’ll be drilling the square out of and make the necessary dimensions. You’ll need a measuring gauge or specific ruler, as well as a T-square, to construct a precise square. 

With this tool, you can construct a perfect square featuring 90-degree angles at each point. Mark the square’s outline on the piece of wood with chalk or pencil.

Step 2: Secure the wood

The following stage is to attach the wood to a flat surface. You may need two sawhorses since they will work better. 

Remember that you’re cutting a square out of the wood; thus, the primary cutting area beneath that square must remain free. For securing both ends of the wood to your sawhorses, use clamps or vises.

Step 3: Drill start square holes

Because you cannot make the initial cut with a jigsaw, you’ll need to cut several starting holes into the piece of wood. A jigsaw is used to see into the wood from its sides, never from above. 

Thus, for internal cuts, you’ll need first to cut holes in the board and then insert your jigsaw knife to start cutting. You’ll need a drill bit big enough to produce a hole big enough for the jigsaw knife to fit. 

Furthermore, it would be best to drip one of those in each of the square’s four corners. To build the corners, you’ll have to spin the jigsaw at about a 90-degree angle, which you cannot do without those beginning holes.

Step 4: Create the cut

All that has been left is to put the jigsaw blade inside, turn it on, and create the cut. Then, cut the square hole out of the piece of wood by following the boundaries you created in the first stage. 

Step 5: Sand down

If required, sand any rough edges that may have been left behind by the jigsaw with a power sander or sandpaper.

2. Using a manual saw

Manual Saws

If you do not have a jigsaw or any power saws, a manual hand saw seems to be another option for cutting a square into the wood. This method is a little more challenging, but it is achievable with enough practice. 

The most important thing to notice is to use a manual saw with a narrow blade. A foxtail saw, for example, would be far too comprehensive for this task. Aside from that, the procedure will be nearly identical to that of a jigsaw puzzle. 

It would be best if you first took your dimensions before securing the wood board to a surface. Then you’ll need to cut the starting holes inside the corners. Notice that they’re large enough to accommodate your hand saw’s whole blade.

If you’re using a manual saw, your beginning holes have to be much bigger than using a jigsaw. It is because you need enough space to move it up and down and the ability to start at each corner.

3. Using a chisel

A Chisel

Using a sledgehammer and a chisel to carve a perfect square out of wood is the next option. Now, keep in mind that this method is the most time-consuming technique, and it needs a great lot of precision and raw muscular force. 

The advantage of this approach is that it does not necessitate power tools or electric sources. Instead, a Red Bull will help you get through the work at hand. You may want to attach the wood piece to a worktable once you’ve taken your measurements. 

Also, you may need something to press against the bottom when pressing it from the top; thus, the wood must be held by an underlying surface; otherwise, it will fracture or split in directions you do not desire. 

After that, line up your chisel within the line on the wood created in the previous step, and strike it. Thanks to its weight, you can do this using a hammer, but a sledgehammer is probably more straightforward.

Strike the chisel forcefully enough to get it through the wood until all its four lines have been chiseled out or when the square is complete. In addition, you can rely on the instructions in this video to better understand how to cut a square hole in wood using a chisel.

Frequently Asked Questions

Here are some related questions we have collected while researching this field, which may benefit you.

1. How to make a perfect square hole in wood? 

Use The 320-Grit Sandpaper For Woodworking

Begin by sanding the entire square with sandpaper. Repeat this process a few times till you reach 320 grit. Your square hole will then be completely smooth.

2. Without a drill, how do you fix a hole in wood? 

If you don’t have access to a drill, you can fix a hole in the wood with a dowel, hand file, sandpaper, or jab saw. First, draw a circle surrounding the hole, then carefully file away any excess wood till the hole is the correct size. Then clean up the mess and continue working on the project. 

3. What is the best way to cut angled notches in wood?  

Drilling a 1/2-inch hole from the woodside is the most straightforward, fastest, and cleanest technique to cut angled notches. Next, the board must be cut using a table saw from its front to the hole. It has a flat, curved base and allows the operator to utilize any angle dependent on the slope of the saw.


Hopefully, after reading our tips on how to cut a square hole in wood before, you could now do it regardless of whether you’re a novice or a skilled woodworker. 

We focused on numerous variables when compiling the list, including cost-effectiveness, level of skill, and safety. So, whichever technique you select in this list, it will be safer to follow.
