Choosing the best worm drive circular saw for your DIY or workshop project can be quite overwhelming due to the thousands of models flooding our shelves. There are many factors to consider when choosing any circular saw.
For instance, users must consider the motor size, bevel angle, user-friendliness, visibility of the cutting line and more.
It’s also important to know that each circular saw model is suitable for a particular task.
For example, a sidewinder saw can’t perform well on applications meant for worm-drive saws.
To make things easier for you, we have addressed some factors to consider when choosing the best worm drive circular saw and also reviewed the top ranked models.
What exactly is a worm drive circular saw?
These circular saws obtained their name from the worm or spiral gear that runs perpendicular to the blade shaft.
Worm-drive saws are ideal where more power and faster cutting are required.
That implies that they can cut through plywood and stud easily for an extended period of time. Its motor is usually parallel to the blade. This motor position ensures that enough torque is delivered to the blade during operation.
However, most worm-drive saws are heavy duty hence come with additional weight. If you don’t have the juice to hold them for a long period of time, you should consider lighter saws.

What should you look for in a worm drive circular saw?
Cutting Line Visibility
During operation, having a clear view of the cut line is very critical. Therefore, if you are right handed, you should go for a worm-drive saw as its blade is on the left side of the motor. A poorly designed saw will obstruct the cutting line with spindle locks, handles and guards.
The better the bevel capability, the easier it will be for you to make angled cuts. Therefore, for improved efficiency, go for tool-less adjustment and positive stops.
A magnesium housing is always the best as it protects the motor without adding extra weight to the tool.
This feature removes dust from the cut line hence you will always see where you are cutting. It also ensures that your working area is tidy.
Blade Changing System
The best worm drive circular saw offers a one-step blade change system (with or without a tool). This minimizes the downtime if blades are switched frequently.

Why Use a Worm Drive Saw: Are there any benefits of using worm-drive circular saws?
Yes, there are. First, worm-drive circular saws are ideal for projects in which lots of plywood have to be cut. These saws offer faster cutting and more power hence can cut through almost anything.
Secondly, their extra weight can act as a guiding mechanism when cutting – you can tilt the work and leave the rest to gravity. The handle is positioned behind the blade rather than beside it.
This provides a longer reach which is suitable for cutting plywood and offers a little margin of safety.

Worm Drive Saws vs Circular Saw Sidewinder
A worm-drive saw’s motor is located at the rear section of the saw. Its power is transferred to the blade via a spiral or worm gear positioned 90 degrees to the blade shaft. This reduces the overall rpm but increases torque. Also, this design makes it easier to attach longer blades to the system.
On the other hand, a sidewinder’s motor uses a spur gear which is line with the rotating blade. This means that sidewinders offer a higher rpm than worm-drives.
Also, a worm-drive has its blade on the left while a sidewinder has its blade on the right. This means that a huge percentage of the weight in a worm-drive is on the right while most of sidewinder’s weight is on the left.
Lastly, worm-drive saws are heavier than sidewinders.
