Are worm gear saws better?
Advantages of a Worm Drive Circular Saw 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.
What are the disadvantages of worm gear drive?
The main disadvantage of worm drives is their low performance offered by these gearbox stages, which can be close to 15% due to the high friction and associated axial stresses.
Why is it called a worm drive saw?
The main difference between these two types of saw lies in the positioning of the motor relative to the blade and how the motor transfers its power to make the blade spin. Worm drive saws are the older type of saw and are so named because they incorporate a 'worm drive' to turn the blade.
Why are worm drive saws more expensive?
The extra metal required for the worm drive, however, significantly increases the weight of the saw. This can lead to fatigue in the hands and shoulders on long workdays. The worm drive saw is thus heavier, more powerful, and more expensive than a regular saw.
Do worm drive saws kick back?
Thought I might add my 2 cents: Kickbacks do happen even if we are careful to let the cut off end drop free. There are several elements that make a kickback not so dangerous with a wormdrive saw. 1. Make sure you are using a quality saw—like Skil, Bosch, Rigid.

How does a worm drive saw work?
In a worm drive saw, the motor transfers the power to the blade through a threaded worm drive down the shaft which turns the pair of gears oriented at 90-degree angle from each other. This causes the saw to spin in reduced rotational speed but with better torque. This torque provides the saw with enough cutting power.
Why is a worm drive saw called a worm drive saw?
A worm drive saw is named so, because it consists of a ‘worm drive’ which is an arrangement of gear. In this arrangement, a worm (which is a gear in the form of a screw) meshes with a worm gear (similar to a spur gear). This results in transmitting more torque and also leads to less spinning speed.
What is a worm drive saw?

What is a cordless sidewinder saw?
Corded direct drive (sidewinder) saws operate at higher blade speeds. Worm drive saws typically weigh more than sidewinders. Cordless sidewinder and rear-handle saws have surpassed corded worm drive saws in both speed and power (torque). No, we’re not kidding. For cordless tools, it is now a handle- and motor-orientation preference.
What makes a worm drive saw narrower?
That makes a worm-drive saw narrower but longer than a sidewinder saw. A spiral gear (the worm gear) turns another gear oriented at 90-degrees, which turns the blade. This increases the torque of the blade, making these saws very powerful.
Which is better, worm drive or blade left?
The narrower, longer, blade-left worm drive saws give right-handed users a better sightline. Of course, blade-right saws give left-handed users a better sightline. Keep in mind that a clear sightline happens with one-handed use. Using the non-dominant hand on the pommel handle can obscure the line. Rear Handle Worm Drive – Blade Left.
Why was the sidewinder saw developed?
Due to different design ideas or patent constraints or a combination of both , the direct drive saw (sidewinder) was later developed featuring the motor next to the blade. This made the saw wider, but also shorter and lighter, than a worm drive saw. It also provided more control for the less experienced user.
When was the worm drive saw invented?
Skilsaw developed the first worm drive saw in the mid-1920s. The motor sat behind the blade, making the tool relatively long and narrow. Worm drive saws still carry this design today. The centerline of the motor sits in-line with the handles, parallel to the plane of the saw blade. A narrow foot lets users—like remodelers, for instance—get into more confined spaces. The longer distance between the handle and the blade also extends a user’s reach while making a cut, which is helpful for jobs such as framing a roof.
Do sidewinders weigh less?
Well, oops, we gave it away already. Sidewinder saw s typically weigh less, so you can more easily hold and maneuver them for unusual cuts. While the heftier tools might dissuade some tradesmen, you can use the weight to your advantage for longer cuts or quick crosscuts in a downward direction. Of course, the other advantage you get with direct-drive sidewinders has to do with blade options. Small brushless 6-1/2″ circular saws make cutting regular sheet goods and framing material super-easy.
