Can A Jigsaw Cut Square In Wood?
Yes, jigsaw can cut square in wood including square inlays and square holes. Yes, it’s challenging, but with enough practice, you can cut a square hole in wood with a jigsaw, like a piece of cake.
Jigsaw is the most popular woodworking tool for cutting square holes since it is not only efficient but also allows for a great amount of precision compared to other methods.
But first, you need to select the right blade type and technique you’re going to use for this entire process. Otherwise, there is a high possibility of making non-straight cuts.
With the right blade and technique, you can cut clean and sharp edges for your square hole making your woodworking project look professional and polished like a pro.
Jigsaw has a unique design compared to other power tools with a narrow, reciprocating blade, allowing it to make intricate cuts with ease.
Jigsaw can cut straight lines, curves, and even square holes, making it an invaluable tool in any woodworker’s arsenal.
I remember the first time I used to cut a square hole in wooden cabinet door after taking advice from professionals in my area, the result was near-perfect after a couple of practice sessions, and I genuinely felt proud.
Don’t worry! I’ll make you feel the same way. It is easy, especially with a tool like jigsaw.
When cutting a square hole with jigsaw make sure to pay close attention to the blade’s movement.
Generally, jigsaws have orbital settings that control the blade’s motion. Therefore, when cutting square holes, better to use a non-orbital or lo-orbital setting to gain a more precise cut.
Let’s have a look at the in-detail view about the type of blades suitable for cutting square holes.
Suitable Jigsaw Blade Types For Cutting Square Holes
Selecting the right jigsaw blade type is crucial for achieving the desired results when cutting square holes in wood.
Jigsaw blades are available in many different types, sizes, and materials. Each one of them is specially designed for various cutting applications.
Here’re some useful things to consider when selecting a jigsaw blade for cutting square hole in wood,
- Tooth count
- Blade material
- Blade width
- T-shank vs U-shank blades
Let’s discuss each of them in detail.
Tool Count
There’s a term called TPI in jigsaw blades. TPI means Teeth Per Inch. So, a blade with a high tooth count (high TPI) usually makes a smoother cut.
But a blade with lower teeth count delivers a faster but rough cut.
When cutting square holes in wood, select a blade with a medium to high TPI to achieve clean cuts.
Blade Material
High carbon steel (HCS) blades are flexible and excellent for cutting softer wood. For harder woods, choose high-speed steel (HSS) blades or bi-steel blades, which can provide high durability and heat resistance.
Therefore, select the blade material by looking at the hardness of the wood you’ve selected to make the square hole.
Blade Width
A narrow jigsaw blade is great for more precise cuts, especially when making tight turns in the corners of the square hole.
Wider blades are more stable than narrow blades when making straight cuts, but they may struggle to control at tight corners.
In a square hole, you need to turn the jigsaw blade 4 times with exact 90-degree angles completing 360 degrees overall. Therefore, in my opinion, narrow jigsaw blades are good to make square hole in wood.
T-shank vs U-shank
T-shank blades are modern and more useful since the installation is easy with no tools needed for many modern jigsaws. U-shank blades need a special tool for installation and are less common.
But U-shank blades can still use if compatible with your jigsaw when cutting a square hole.
For example, when I cut square holes in a plywood bookshelf, I used a 12 TPI T-shank HCS blade, which provided the perfect balance of smoothness and cutting speed.
As you can see, jigsaw is more than capable of cutting square holes in wood, thanks to its unique design and versatility.
By selecting the appropriate blade type and employing the correct techniques, you can achieve clean, professional-looking square holes for your woodworking projects.
Let’s see what are the key factors that you should consider before making a square hole in wood with a jigsaw.
Factors To Consider When Cutting A Square Hole In Wood With A Jigsaw
When cutting a square hole in wood using a jigsaw, several factors affect the quality and the ease of your cuts.
As per my experience, these factors can make all the difference when cutting a square hole.
Here’re the factors to consider when cutting a square hole in wood with a jigsaw,
- Wood type
- Wood thickness
- Blade selection
- Jigsaw speed adjustment
- Orbital action settings
Let’s have a look at each of the above factors in detail to make your square cut on wood easily with a jigsaw.
1. Wood Type
The type of the wood you’re working on is a crucial factor when cutting a square hole since that determines the ease and precision of your cuts.
Softwoods like pine and cedar are easier to cut with a jigsaw while hardwoods like oak and maple are challenging due to their high density.
Make sure to select a suitable blade type when dealing with different wood types to make smooth cuts without damaging or chipping the material.
2. Wood Thickness
The thickness of the wood plank you’re going to cut is important to consider when selecting jigsaw blades.
You need to make sure that the jigsaw blade you selected is able to reach the material entirely.
Consider the cutting capacity of your jigsaw and select the blade that can accommodate the wood’s thickness.
For example, when cutting thicker wood, you need to have a jigsaw blade with a slower cutting speed and more powerful jigsaw models.
3. Blade Selection
As I already mentioned earlier, you need to have a good understanding about T-shank blades, U-shank blades, tooth count of the blade, and the material considerations before making the cut.
T-shank and U-shank have different installation methods. T-shank blades are popular, and modern need no tool for the installation process, and compatible with almost all modern jigsaws.
But U-shank blades need a special tool for the installation and may not be compatible with all the modern jigsaws.
Therefore, select the blade type based on your jigsaw model reading the manufacturer’s guide.
Selecting the right blade tooth count (TPI) is essential to make smoother and more precise cuts.
As a general rule, go for higher TPI blades for smoother cuts and lower TPI blades for faster and rougher cuts.
High-carbon steel (HCS) blades work well for cutting square holes in softwoods while high-speed steel or bi-metal blades are great for hardwoods due to their high durability and heat resistance.
4. Jigsaw Speed Adjustment
Adjusting the cutting speed of your jigsaw is important to optimize the cutting performance based on the material.
Mostly, slower speeds of jigsaw are great for hardwoods and thicker materials, while faster speeds are suitable for cutting softwoods and thinner materials.
Many of the jigsaws have the facility to control the speed setting. You can fine-tune the cutting speed of jigsaw based on the type of wood you got.
5. Orbital Action Settings
Orbital action settings control the blade’s movement during cutting, affecting the cut’s speed and smoothness.
For cutting square hole in wood, it’s best to use a non-orbital or low orbital setting to ensure more precise cuts.
Be sure to consult your jigsaw manual for specific guidance on adjusting the orbital action for your particular model.
Understanding and considering these factors when cutting a square hole in wood with a jigsaw can lead to better results and a more enjoyable woodworking experience.
By selecting the right blade, adjusting the jigsaw’s speed and control settings, and taking the wood type and thickness into account, you’ll be well on your way to cutting perfect square holes in any wood.
Let’s see what tools you should use with a jigsaw when cutting a square hole in wood.
Tools For Cutting Square Hole In Wood
- Pencil or marking tool
- Measuring tape
- Framing square or straightedge
- Fine grit sandpaper
- Sanding blocks or oscillating tool

Enough chit-chats! Let’s head into the hot topic of discussing the procedure of cutting a square hole with a jigsaw correctly without messing things up.
How To Cut A Square Hole In Wood With A Jigsaw?
Cutting a square hole in wood is a challenging task, but with the right technique and some practice, you can achieve excellent results.
Here’re the steps you need to follow when cutting a square hole in wood with a jigsaw,
- Measure and mark the square hole area.
- Secure the wood.
- Create starter holes using a drill.
- Start cutting the market area.
- Smoothen the square cut by sanding.
Let’s have a look at each of the above steps in detail to cut square holes in any wood without making any mistakes.
1. Measure And Mark The Square Hole Area
First, you need to mark the square hole area before starting to make the cuts.
Take the measuring tape and carpenter’s square to get accurate measurements of the square you’re going to gut and mark with the pencil or marking tool.
Double-check the measurements you’ve taken before moving on to the next step since errors at this stage might lead to uneven cuts.
After taking the measurements, take the straight edge or carpenter’s square to mark the 90-degree angle of the square hole.
Check whether the lines are parallel with opposite lines and have a 90-degree angle in the corners.
Lines you marked with the pencil should be visible since you’ll have to guide the jigsaw along those lines to make straight cuts.
2. Secure The Wood
Next, you need to secure the wood to keep it steady without letting it make any individual movements during the cutting process.
To do that, you can use a sawhorse, table edges, or a workbench with clamps to hold the wood firmly in place.
Make sure the wood is stable and won’t shift during the cutting process.
Plus, make sure the area you’ll be cutting the square hole has adequate support underneath.
Having good support underneath helps prevent the jigsaw blade from binding or causing the wood to splinter when you cut.
3. Create Starter Holes Using A Drill
Before you start cutting the square hole in the wood with your jigsaw, you’ll need to create starter holes using a drill.
The starter hole is also known as the pilot hole.
Choose a drill bit slightly larger than your jigsaw blade’s width and make sure to drill the holes in each corner of the marked square hole.
Making a pilot hole before starting to cut the square hole in the wood allows the jigsaw blade to fit comfortably and ensures a clean starting point for your cuts.
When drilling the pilot holes, make sure they’re located inside the marked square hole, close to the corners but not too close to the edge.
This will help prevent the wood from splintering or cracking during the cutting process.
4. Start Cutting the Marked Area
Insert the jigsaw blade into one of the starter holes and begin cutting along the marked lines by keeping your hands steady.
Take the control of jigsaw with your hands without letting the machine move freely to make smooth and straight cuts with ease.
Make sure to follow the markings closely and keep a steady hand to ensure accurate cuts.
Don’t rush the process; take your time to achieve clean, precise lines to get a square hole as you want.
As you cut, sawdust can build up and make it difficult to see your markings. Plus, sawdust can cause skin irritations.
In order to remove sawdust from the surface, clean the area with a clean rag or use a proper dust collection pipe system to collect sawdust.
The collected sawdust can use to make fertilizer upon drying with a dryer.
This will help maintain visibility and ensure you’re staying on track with your markings.
5. Smoothen the Square Cut by Sanding
Once you’ve completed making square hole in wood, use sandpaper or a power sander to smooth the edges of the square hole.
Start with a coarse grit sandpaper and work your way up to a finer grit for a smooth finish.
Make sure to apply even pressure when sanding to even out the surrounding wood color and to avoid surrounding are damaging due to rough sanding.
This step will help eliminate any burrs or rough edges left behind by the jigsaw.
Now, focus closely on square hole, as these areas may have some burrs or rough edges that need extra attention.
Use a small, flat file or sandpaper wrapped around a flat object to carefully remove any imperfections and achieve a smooth finish.
This attention to detail will ensure your square hole looks professional and polished and super smooth.
By following these steps and incorporating the tips provided, you can successfully cut a square hole in wood with a jigsaw.
Congrats folks! Now you know how to cut a square hole in wood with a jigsaw perfectly following the correct procedure.
Practice makes perfect, so don’t be discouraged if your first attempt isn’t flawless. With time and experience, you’ll be able to create clean, accurate square holes in wood with ease.
