There’s much debate about the similarities and differences between Circular saws and Skill Saws.
The Circular Saw vs. Skill Saw debate is similar to the rectangle and square adage. Essentially, every skill saw is a circular saw, but not all circular saws are skill saws.
A circular saw is a power tool that allows you to cut through material quickly. It can either be cordless or corded. There are two primary types of hand-held circular saws: The Sidewinder and Worm Drive
So, What’s a Circular Saw?
A Sidewinder circular saw utilizes a motor with a spur-gear. Because of how this gear is designed, the motor must always be in line with the spinning gear, thereby making the blade spin very fast.

A Worm Drive circular saw, on the other hand, has a motor located at the rear end of the saw. Additionally, it features a pair of gears oriented at a 90-degree angle that help to transfer power to the blade.
