Worm Drive Circular Saw vs Direct Drive: Questions to Ask Yourself

What type of circular saw should you buy? It depends. Here are several factors that can influence your decision:

  • What are you using the saw for?
  • How much power do you need?
  • Are you a righty or a lefty?
  • How strong are you?
  • How much experience do you have?
  • What’s your budget?

Worm Drive

Advantages of a Worm Drive Circular Saw

The centerline of the motor on a worm drive saw is parallel to the plane of the saw blade, giving the saw a narrow profile that allows users to get into more confined spaces. The longer distance between the handle and the blade extends your reach while making a cut, which is helpful for crosscutting sheet goods.

A worm drive also has larger gear teeth with more load-carrying capacity than a direct drive, which provides more power but also adds weight. The average worm drive saw weighs in at about 13-14 lbs. A pro-grade worm-drive saw costs about $150 to $200.

Sidewinder circular saw

Advantages of a Direct Drive Circular Saw

The blade on a direct drive saw (often called a sidewinder) is next to the motor, creating a wider profile but shorter overall length. Because the handle is closer to the blade the reach is reduced, but this can provide more control for a less-experienced user. Direct drive saws are lighter (9-10 lbs.), making them ideal for less-demanding applications or a whole bunch of repetitive cutting. A pro-grade sidewinder costs between $125 and $150.

Left handed saw

Righty vs. Lefty Circular Saws

Whether a user is right or left-handed does not confine him or her to one type of circular saw, but consider this: The blade on a worm-drive saw is on the left side, so it’s easier for a right-handed operator to see the cutline. The blade is on the right side of a direct-dive, making it easier to see the cutline for a lefty.

Circular saw

Pro or DIYer

A direct-drive saw is lighter, more compact and easier to manage, making it ideal for DIY users, but a pro-grade sidewinder will still have plenty of power for most jobsite tasks.

Bottom Line About Worm Drive Circular Saws vs Direct Drive

One of the most important features of a saw is how it feels. When choosing a new tool, try it out whenever possible. Feeling comfortable and safe using a tool is more important than any spec sheet.
