Invented in the late 1700s, the circular saw changed the game when it came to woodcutting and carpentry. Its rotating blade allowed workers to cut through wood more quickly compared to back and forth reciprocating saw blades. It also minimized the amount of space needed to operate a saw.
Today, the game has changed even further with compact and portable mini circular saws. Whether looking for a craft saw or a supplement to your carpenter’s toolkit, we’ve put together a list to help you find the best mini circular saw to take care of business.

How Does a Mini Circular Saw Work?
Many people love using circular saws but don’t have a clue how they work. Does this sound familiar to you? Well, you’re in luck because we’re going to reveal the secret of mini circular saw operation.
The mini circular saw operates a lot like a standard size worm drive saw. In fact, many mini circular saws use the worm drive to operate their blades. This is primarily because this type of drive is ideal for saws where the motor must be behind the blade, e.g., a compact, handheld tool.
Let’s take a step back.
There are three main components to a mini circular saw, the motor, the drive, and the blade. They are the same even for professional chainsaws. The motor transfers power to the drive, which then turns the blade. A worm drive uses a pair of gears oriented at a 90-degree angle to one another to transfer the power from the motor to the blade.
This is a great type of drive for creating a handheld circular saw or one with a left blade orientation. It also helps improved torque and makes the saw more durable, so it lasts longer when cutting through dense materials.
What To Consider Before You Buy
Naturally, you now want a mini circular saw that can you can use just like a standard circular saw, only without the weight and heft. This is easy enough to accomplish by picking out any compact or mini circular saw on the market.
Believe it or not, there are a lot of different features to keep an eye out for in your purchase.
All of the potential features listed below can be found in one or several different mini circular saws. You’ll want to select the ones that best meet your needs and enhance your use of these power tools.
Take a look for yourself!
- An adjustable cutting depth allows you to control how deeply the blade cuts through certain materials.
- An adjustable bevel allows you to cut materials at different angles up to 45 degrees.
- Cordless circular saws usually have a rechargeable battery.
- Laser guides allow you to cut a straighter line by following a thin line of light projected by a laser in the saw case.
- Higher amp circular saws have more power for faster cutting and cutting through dense materials.
- Two blade positioning allows you to set the blade outside of the guard for flush cuts or using sanding and abrasive blades.
Mini Circular Saw Blades
Great, you’ve found the best mini circular saw. But now, you have no idea how to use all these blades! Take a deep breath and relax. We’ll help explain the basics of different types of saw blades.
What the Tungsten Carbide Blade!?
Carbide tipped for increased strength and durability, these blades are great for wood, plastic, and composite materials. The carbide tip is attached onto the steel blade using a soldering technique known as brazing.
Also known as high-speed steel blades, these are made from a high-quality, strong steel, and have more teeth for cutting. Some have up to 60 large, sharply angled teeth. They’re great for cutting a variety of materials including:
- Thin Sheet Metal
These have very small teeth or no teeth at all and the edge is covered in a fine layer of diamond grit. As you may already know, diamonds are the hardest substance on Earth and make for excellent cutting tools. They are great for cutting through ceramic tile, stone tile, backer board, and cement.
But Wait, There’s More…
Mini Circular Saw Cordless
Imagine that you’re a carpenter working on-site without electricity. You need to make several small adjustments to a 2″ x 4″ before you can nail it into place. Thank goodness you have that cordless mini circular saw!
Or, you’re happily working on a carpentry project in one room and suddenly realize there are a few other small projects you can take care of while you have that compact circular saw out. You get up and take that cordless circular saw along without a second thought.
Isn’t that great?
These rechargeable battery powered saws are ideal for environments without easy access to a wall outlet. Cordless power tools have come a long way in the past several decades. These days, they are nearly as powerful and durable as a traditional corded power tool.
Because they use lithium-ion batteries. These batteries are lightweight, have a high energy density, and recharge easily with the help of LiPo-chargers. They also tend to provide a consistent flow of energy right up until the battery has drained.
If you’re frequently working on sites without power, don’t bring along Yamaha EF2000is generator for just one tool. Turn to a cordless mini circular saw to do the job.
You may not have realized it, but compact circular saws can still do a lot of damage if not used appropriately. After all, their blades are usually diamond or carbide tipped and spin at thousands of rotations per minute! Safety is best kept in mind when using one of these power tools.
What Do You Need To Know?
The first thing to do is use that circular saw in a clean and dry area. Ideally, you will be working in the garage, on a construction site, or in your craft room. The space should also be well-lit so that you can see what you’re doing.
Here are a few other tips:
- Wear safety glasses when operating the circular saw.
- Where a facemask or respirator, if you do a lot of cutting.
- Keep the hand and lower blade guard in place. Do not remove these!
- Don’t operate near pets or children.
- Keep your hands away from the blade while it’s spinning.
- Use sharp blades for cutting. Dull blades can break or catch.
- Keep all cords clear of the cutting area.
Of course, these are just a few of the more common safety steps to remember. Naturally, you’ll want to read through the instruction manual thoroughly before using any power tool.
Okay, you have purchased a circular saw and kept in the box for a couple of months until you finally found a project to use it on. Sadly, when you plug it in and press the power button, nothing happens. You’ve got a dud!
You reach out to the manufacturer, only to find that you’re past the return period or a money back guarantee. On top of that, they don’t offer a product warranty! Disappointed, your only option is to purchase another mini circular saw.
And just think, if you had taken the time to look for product warranty, you could get a replacement without having to pay for a new one.
Well, you can at least keep this from happening again.
Next time, check for a warranty from the manufacturer before purchase. Most mini circular saw companies offer a warranty length of between 1 to 5 years. These are usually limited warranties, meaning that the manufacturer will replace the product if it is defective in some way that causes it to break in the box or break during use.
Unfortunately, saw blades that come with your purchase are not always covered under warranty. If you buy the blades separately, these may have their own warranty you can rely on if found to be defective.
