Let us first resolve a misconception. People usually think that regular circular saws/direct drive saws and worm drive saws are two saws that are different. That is not true. In fact, a worm drive saw is a special type of direct-drive circular saw. So, what is special about it?

Here, you will have a very powerful motor attached to the rear of the worm gear. Driving through two gears, each set at 90 degrees, the spinning blade, and the worm drive motor produce a torque and blade speed of more than 4500 Rotations per Minute (RPM). Moreover, the saw is longer and bulkier than any direct-drive saw.

The Key Features Of Worm Drive Circular Saw

Features of worm drive circular saw

Every saw has the same job- cut-through material. But some are famous for special specifications. Here are three features of the Worm drive circular saw that made it well-known for accurate cuts.

  • More confined spaces– In the worm drive circular saw, the centreline of the motor is parallel to the plane of the saw blade with predominantly magnesium construction. Consequently, a narrow profile is produced. This will give you more confined space.
  • Best for cross-cutting sheet goods– The distance between the blade and the handle is long. As a result, your reach is extended while making a cut, helping to tack tight spaces during rip-cutting and cross-cutting in DIY projects, if you are a less experienced user who could use some maneuvering.
  • More load-carrying capacity– It has larger spur gear teeth giving it a more load-carrying capacity that gives you a higher torque that is useful during tougher jobs like cutting through knotty wood you need more control and more power.

Safe Handling Of Worm Drive Circular Saw

No matter where you work, if you are working with machines, you must learn how to properly use them and hold the blade right, whether you fall in the category of left-handed users or right-handed users. The same logic goes for Worm Drive Circular Saw. 

You can learn more about it in the user manual that comes with buying the specific models. Here, we will have a take into key features of Worm Drive Circular Saw that must be handled in a proper way.

Rear Motor

The speed is usually lower in comparison with the regular circular saw, so this will be a great choice for amateurs and newbies.

Using the Torque

When you are dealing with wood, torque is the most important factor to consider. If the torque is good, you will have a better output from the saw, and your performance will be seamless.

Long Saw

Moreover, most Worm Drives Saw have a simple design- having the blade in the front and the motor on the rear. It might give you an impression that the blade is longer than it is.

The Weight

It’s true, Worm Drive Circular Saw carries extra weight than its other circular saw counterparts. This gives the machine more strength and durability, but at the same time, it comes with a caution. 

You will have put more than average strength on the saw while operating. Otherwise, you might lose control of it and get hurt. If you are not physically strong enough, it is advised not to use these models.

How to Change the Oil in a Worm-Drive Circular Saw?

This oil, in turn, will get contaminated through use. The steps for changing the oils are given below;

  • Free run the saw for about three minutes. This will warm the oil.
  • Using a wrench, remove the spindle lock/oil filter.
  • Next, tip the saw on its side and pour out the oil into a container for recycling.
  • Refill the crankcase to the level specified with a funnel of ¼ inches or smaller.
  • Use the sight glass for checking and refilling easier.
