Worm Drive Circular Saw vs Regular: Have You Got the Right One?

Written by | Updated On July 7, 2020

Are you confused between worm drive circular saw vs regular saw as both looks almost the same? Well, dig some more and you will find eye-opening differences between the two types.

Let alone the beginner, even a lot of professionals don’t know about them deeply and keep struggling with the wrong tool. If you are trying to cut heavy and thick boards with a regular circular saw, our condolences are with you.

So, don’t just take shots in the dark and know more about sidewinder vs. worm drive saw. Here, the following parameters will help you choose the right tool for the task.

  • Mechanical Difference
  • Power output
  • Maintenance
  • Handling
  • Weight
  • Preference
  • Cost

What is a Worm Drive on a Circular Saw?

Worm drive on a circular saw means that it has a motor connected to the blade by a worm gear. A worm gear consists of two parts where one is called worm screw and another is worm wheel.

As you can see one in the picture, this allows the motor of the circular saw to be placed just behind the blade parallelly.

So, why is it called a worm drive?

Worm Gear

It is called worm drive because of the meaning of the word ‘worm’. In a mechanical dictionary, it means something spiral and the screw-shaped top part has spiral linings.

That’s all about worm drive and a thorough discussion on worm drive saw vs. direct drive saw is the next item on the menu.

Worm Drive Circular Saw vs Regular Saw

The following criterion will give you a proper idea about the differences between a worm drive and a regular circular saw.

Mechanical Difference:

The first big and most important difference is in the mechanism of both types. A regular circular saw has a design where the motor is placed beside the blade. Or you can say they are perpendicular to each other, and the motor is directly connected to the blade. That is the reason it is called a direct-drive or sidewinder circular saw.

On the other hand, a worm drive saw has a mechanical design where the motor is right behind the blade. So, instead of connecting directly, the motor and the blade is connected by a worm gear.

Power output:

Because of the mechanical difference of those saw types, there is an output power difference. But first, you have to understand two things where one is RPM and another is Torque.

RPM means Rotations Per Minute and it resembles the blade’s rotating speed in this matter. Torque, however, means how smoothly a saw can cut large and thick pieces. Rotations can be limited but techniques can be applied to increase the torque of a device.

Now, let’s get back to the discussion we were having. The facts are that regular circular saw has average speed of 6000 RPM and worm drive saw provides around 4500 RPM. But the torque is higher in the worm drive because of the worm gear mechanism.

For powerful cutting, low RPM and high torque is the clear winner and worm drive can get serious industrial projects done. High RPM and low torque provided by a sidewinder saw are perfect for mid-range tasks and DIY projects.

As we are focusing on powerful and deep cutting capabilities, you should also know about miter saw. Reading circular saw vs. miter saw can help you get an idea about another useful tool.

Getting into Tight Spaces:

You know how one needs to improvise to make crafts and work in tight spaces. In many situations, you would wish if you had a tool to do the cut. A worm drive circular saw is perfect for this kind of task.

Why? Because the motor is placed parallelly right behind the blade. As a result, it is slimmer than the regular saw. Regular or sidewinder saw has the motor on the sides that makes it wider and requires more space to cut.

Maintenance:

Worm drive circular saw requires more maintenance work. The regular saw also needs some maintenance, but the other one requires more attention. You have to regularly lubricate its blade to keep cutting large boards smoothly.

Weight:

If you are looking for a lightweight circular saw, direct drive circular saw is the one, and it is approximately 2-5 pounds lighter than the worm drive saw.

Preference:

After talking to some carpenters, we saw some biasness in their tool preference. Where the East hails sidewinders, the people of the West and Midwest loves worm drive saw more.

But that is not a 100% correct statement because professionals don’t choose tools thinking which part of the country they are on. It is the task that matters the most.

However, biasness can be seen between the right-handed and the left-handed carpenters. Because of the blade and handle positioning, lefties prefer regular circular saw and vice-versa.

Cost:

The last parameter of the worm drive circular saw vs. regular debate is the price point. After doing market research, you will find that regular saw costs less than worm drive saw

Worm drive vs standard circular saw: Which is easier to use?

The pick is pretty obvious here, and it is the standard circular saw. Compact-size and lightweight features are the reasons behind it. Now, do you want to know about another type of circular saw that is even better? It is the best cordless circular saw and without the cords, you can cut plywood quickly and safely.

What are the advantages of a worm drive circular saw?

We have declared that direct-drive circular saw is easier to use but it should not lead you to take a decision. You should also take the advantages of a worm drive into account. First of all, it has the cutting capability unmatched by the other one.

You may find the extra weight as a disadvantage but it makes the saw more stable. So, you will get less kickbacks while cutting plywood or other material.

Regardless to say, worm drive circular saw is capable of reaching further and tight spaces, which is helpful for construction workers. Only getting the best worm drive circular saw can ensure all of those features.

What are the advantages of a direct-drive circular saw?

Apart from the lightweight and compact-size features, sidewinders are also preferred for its low cost and low maintenance. The higher RPM makes it perfect for cross cuts and crafting softer woods.

Conclusion

So, what do you think about worm drive circular saw vs. regular saw comparison? Are you considering powerful cutting capabilities? Or, budget and easy handling features? The choice is clear.

Get worm drive circular saw for heavier tasks and direct-drive circular saw for mid-range or smaller tasks. Whatever it is, please make sure that you stay safe by reading how to use a circular saw.
