Here is an explanation of the differences between sidewinder and worm drive circular saws taken from an article in Fine Home Building magazine… www.finehomebuilding.com. (One of our favorite mags).
So just what is the difference between these two styles of saw?Let’s take a closer look.
Clearly these two saws look different and that difference is due to the position of the motor and gearing.
A sidewinder uses a motor with what’s technically called a spur-gear. By nature of this gear the motor must be in line with the spinning blade and this means the blade spins fast in the neighborhood of 6000 rpm. As you can see the motor position allows for a fairly compact lightweight saw.
A wormdrive motor is at the rear of the saw and its power is transferred to the blade with a pair of gears that are oriented at a 90 degree angle. This gear setup reduces the speed of the blade typically in the neighborhood of 4500 RPM but increases torque. Obviously this motor position leads to a longer saw but it’s also significantly heavier.
There are exceptions but by and large a sidewinder will have the blade on the right and a worm drive will have the blade on the left. Depending on whether you are righty or lefty this will affect sightlines and working habits. Let’s assume you’re a righty…
With a sidewinder the blade is on the right side and the weight of the tool is on the left. This design keeps the weight of the tool on the solid part of the board rather than the cutoff. The tradeoff is that it’s more difficult to see the cutline. Typically cuts are made on sawhorses or right on the stack of lumber.However the lightweight of a sidewinder makes it a good choice for working overhead. Some will also argue that the blade position helps ensure that both hands are kept a safe distance from the cut. In use the compact lightweight sidewinder is much easier to handle
With a wormdrive the blade is on the left side leaving the majority of the weight on the right. This design changes the way the blade is installed. It also makes it super easy to follow a cutline but can be dicey if you’re used to working on sawhorses. Many wormdrive users either cut right on the stack of lumber or take advantage of the tool’s weight by cutting boards in a handheld position. The extra length of the tool also makes it handy for gang cutting wide stacks of lumber or long sheet goods. Its shape also makes plunge cuts easier.
