Best Worm Drive Saws – Powerful Yet Affordable Models

Worm drive saws share the market with the standard sidewinder circular saws. Though similar in construction and appearance, the two are made for different tasks. Sidewinders are there for light and quick works, while the worm drive models can be used for more serious projects.

To pick the appropriate worm drive saw, there are many things to take into consideration, such as build quality, motor quality, torque, maximum cut depth, bevel angle capacity, housing material, how easy it is to change out a worn blade, and many more.

Circular vs Worm Drive Saws

While many people use both circular and worm drive saws, the two types do have some major differences. Here’s a word or two about each of them.

Circular saws are great for when you need to cut up some plywood sheets or thinner wood panels. On the other hand, if you need more power, the worm drive saw is the way to go. Be careful, though, as these saws pack a significantly stronger punch than their circular cousins due to the much higher torque. As such, they can produce quite a bit of kickback on startup.

Aside from that, worm drive saws are not available in battery-powered versions as the power and torque requirements far exceed current battery technology.

Also, they tend to have more rugged housings to be able to handle the nature of the work they’re intended for. However, you can also find cheaper and less powerful worm drive saws in plastic housings. Owing to the fact that the housings are mostly made of metal, worm drive saws tend to be heavier and less maneuverable than the circular variety.

Worm drive saws have a greater reach, as the blade is positioned 4-5 inches in front of the housing. Also, it’s easier to track their progress along the board, thanks to that gap. As the handles are behind the blade, worm drive saws are safer to use than the sidewinders, without extensive safety gear like chaps.

Finally, worm drive saws tend to be more expensive due to the more powerful motor and the more complicated worm drive (vis-à-vis the direct-drive circular saws).

How a Worm Drive Saw Works

The motor of a worm drive saw is located behind the blade, instead of beside it (like on sidewinder saws). As such, manufacturers would be able to fit motors of greater power and torque. 

The power is transferred to the front through either a worm gear or spiral, which sit at a 90-degree angle to the blade. In the process, some of the rpm is lost but more torque is preserved.

Additionally, this type of mechanical power transmission allows worm drive saws to use bigger blades than circular saws.

Generally, worm drive saws are built with the blades on the left side, while sidewinders have the blades on the right. The left-side blade affords better visibility when cutting. Also, this design puts most of the weight on the right side so it’s easier for right-handed people to control.

Features to Consider in Worm Drive Saws

Dust Blower

A built-in dust blower is considered a convenient extra and many models don’t come with it, especially in the lower price tiers. However, it’s become sort of a standard among the premium models. Its main function is to remove the dust from your cutting line and keep the work area clean. This should let you work faster and have a better line of sight.

Blade Change Mechanism

The ability to change blades with little hassle is very important, especially if you intend to use your worm drive saw extensively. Basically, there are two types of blade-changing mechanisms used on worm drive saws nowadays – tool-free and tool-assisted.

Tool-free mechanisms are simple and easy to use. Typically, you will only need to press a button or two to release the old blade and click the new one into place.

On the flipside, some saws require the use of screwdrivers and wrenches to replace the blade. If you intend to use the saw every once in a while or for short and simple projects, this system might be ok for you.

However, if you plan on using it frequently, it is recommended to get a saw that allows tool-free blade change. Also, if you plan to work on heavy-duty projects, it may be better to have a model which requires tools to change the blade.

Bevel Capacity

Another thing to consider when shopping for a worm drive saw is the bevel capacity. All models offer the ability to cut at some bevel angle, but the best one will let you cut at greater angles.

Some models also come with bevel stops at commonly used angles. This feature can come in very handy as you can lock the saw into position and cut without worrying that you’ll mess up the cut.

Commonly, worm drive saws feature at least 45-degree bevel. Some models, however, can go over 50 degrees. Common bevel stops include 22.5 degrees, 45 degrees, and 51.5 degrees (for the ones with greater bevel capacity).

Motor Housing

When shopping for a worm drive saw, you should also take into consideration the robustness of the motor housing and its material. The housing is usually metal, though some of the most affordable models may have plastic housings, which are lighter but less sturdy and durable.

On the other hand, metal housings are stronger and can take more punishment. Magnesium offers the best weight-performance ratio as it’s lightweight and very sturdy. Aluminum is another popular housing material.

Maximum Cutting Depth

The maximum cutting depth is an important aspect of worm drive saws. It varies from model to model and mostly depends on the size of the blade and its positioning. Generally, you should choose a model according to the intended tasks.

However, the industry-standard maximum depth is around 2-3/8”. Smaller models might have shallower cutting depth. You can also find models with greater cutting depth.

Visibility of the Cutting Line

It is very important for a worm drive saw to give you a clear line of sight. However, some poorly designed models are not as good at it.

Models with poor line of sight are harder to use especially when you’re trying to cut in a straight line. They are also more prone to causing injuries.

Final Thoughts

Worm drive saws are there for tasks that are beyond the regular sidewinders. They offer greater cutting power, reach, and durability. However, they are more robust and require more strength to wield, especially at start-up.

Some of the main things to look for in a quality worm drive saw include a powerful motor and a sturdy and well-designed housing. Magnesium and aluminum housings are the best options. You’d want to avoid plastic ones.

Also, a well-made worm drive saw should feature good bevel capacity, clear line of sight, and easy maintenance. A built-in dust blower is nice to have but restricted to the high-end models.
