Difference Between Worm Drive and Sidewinder

When it comes to cut forest, there are two main ability tools used – the round saw and the sabre saw. Circular saws are used for almost 99 percent of the cutting on framing jobs. Sabre saws are used for notching, curve cutting, and making irregular holes. In terms of pattern, round saws come in ii types – worm drives and sidewinders (sometimes called spur gears).

What is Worm Drive?

Worm Drive (or Worm Gear) is a staggered shaft gear organisation in which a worm gear in the shaft has a screw type thread and the power is transferred from one shaft to some other, with each gear set at xc degrees. A worm gear combines features of both a conventional gear drive and a power screw. The shafts are perpendicular to each other and do not intersect each other. In a worm gear assembly, y’all can see a gear is continued to an input shaft and the gear is zilch only a screw. As the screw rotates, information technology turns the gear with which information technology has been meshed which in turn is connected to an output shaft. An electrical motor powers the worm which rotates against the worm cycle, providing high reduction ratios and correspondingly high torque.

What is Sidewinder?

A sidewinder round saw, as the name suggests, is a power tool with the motor mounted off to one side of the saw, which directly turns the shaft that turns it around. Also known as in-line round saws, sidewinders use motor that runs parallel to the blade which ways the blade spins much faster, typically around 6,000 rpm. The motor position makes it fairly compact and lightweight. For the most part, a sidewinder has a blade on the correct, as opposed to a worm bulldoze, where the blade is on the left. They are commonly used to cutting through masonry, wood, metal, and plastic for home improvement projects.

Departure between Worm Bulldoze and Sidewinder

Motor Placement

– Both the circular saws look very different and that divergence is generally considering of the position of the motor. A sidewinder uses a motor which is technically called a spur gear. The motor armature runs parallel to the bract and the motor is mounted to 1 side of the blade, which directly turns the shaft. On a worm drive, the motor sits backside the blade and the armature is placed perpendicular to the rotation of the blade.

Blade Orientation

– Perhaps for the most part, a sidewinder circular saw has a correct-side blade placement, merely many manufacturers today produce circular saws with a left-side blade placement. A worm bulldoze, on the other hand, has the blade to the left side. Then, depending on whether you lot’re left handed or right handed, it will by and large affect your sightline to the blade and how you’re going to use the tool.


 – A sidewinder is compact and lightweight, which makes it easier to handle, peculiarly when you’re working overhead. Also, the bract placement ensures that both hands are at a safe altitude from the cut. A worm drive has its motor mounted to the rear of the blade, which results in less speed but more than torque. Likewise, the blade is on the left hand side, which places the majority of the motor weight on the right, making it easier to follow the cut line, cheers to the improved sightline. However, worm drives are heavy and slower.

Summary of Worm Drive vs. Sidewinder

While worm drives, in regard to design, are used in a broad range of construction works, the sidewinders are lite and generally easier to handle, making a improve choice for fine work. A worm drive is heavy and slower, but it has better load conveying capacity. Information technology draws ability through the two gears that are gear up at 90 degrees. 1 downside to a worm bulldoze is that its gear railroad train requires oil which is an additional hassle. This is not the case with sidewinders; they don’t need oil. At the end of the twenty-four hour period, both are really good tools and no one style is improve than the other. It comes downwards to how you prefer to piece of work.

Are worm drive saws better?

A worm bulldoze circular saw combines features of both a conventional gear drive and a power screw and this gear assembly reduces the speed of the blade, typically in the range of around 4,500 rpm, but it really increases the torque. However, it’s a lot heavier than a sidewinder.

What are the advantages of a worm drive circular saw?

A worm drive has a blade on the left that ways the bulk of the motor weight is on the right which makes it easier to follow a cut line. Too, the load carrying capacity of a worm drive is amend than a sidewinder.

Do worm drive saws kick dorsum?

Worm drives offering gear reduction and increased torque, and the fact that they cannot plough backward, eliminates the kickback.

Why are there no worm drive saws in the UK?

Worm drive circular saws practice not comply with the European Health & Safety regulations, and so they are not very common in the Great britain.

What makes a worm drive saw ideal for framing?

The extra length of the worm bulldoze and the torque delivery make it ideal for cutting wide stacks of lumber and for framing or other major renovation works.
