- Long battery life
- Handy rafter hook
- More expensive than other models
- Some may find the spindle lock is awkwardly positioned
Due to the direct drive system that powers the motor, the DeWalt DCS577X1 is not officially a ‘true’ worm drive saw. Neither the less, this does not stop it from delivering a massive 2400 watts of power. Furthermore, the inclusion of the brushless motor ensures this is a saw that will last you many years into the future.
The in-built dust blower maintains clear cutting visibility throughout cutting. Cutting depth is easy to adjust and the gauge is super visible. An electric brake to help stop the blade when needed. Blade sits to the left.

As with the above model, the Makita XSR01PT is not a true worm drive saw. Don’t let you put this off however, as this is still as a wonderfully powerful saw that can be used absolutely anywhere.
It features a special helical gear design that brings the gears together at a 45-degree angle rather than 90. Also, the motor is brushless, benefits of which include longer run times and reduced heat buildup.
Inbuilt speed change technology allows quick alterations to the torque and cutting speeds during a job. Cordless, so you aren’t restricted to where you can work. Slightly lighter than the worm drive saws featured on this list. Blade sits to the left.
53-degree bevel capacity with stops at 22.5, 45 and 53. Maximum cutting depth at 90 degrees of 2-9/16’’. Also included are two 36V LXT lithium-ion batteries. Priced marginally higher than worm drive saws. Doesn’t have a cut line dust blower.
The best way to describe the Makita XSR01PT is ‘efficient power’. This is a professional quality tool that knows exactly how much power you need at any given moment to make sure the task at hand is made no harder than it needs to be.
When deciding on a worm drive saw, there are several factors you must take into consideration. The following buyer’s guide will highlight each factor to ease your decision-making process.
Key Factors to Consider
The motor is the most vital component of a worm drive saw. A weak and unreliable motor is no good for anyone. These days, it’s pretty standard to get a 15 amp that delivers around 4,500 to 5400 RPM. If you find any that are less, you are likely going to get an unpowered model.
Pay attention to the saws cutting depth at both 90 and 45-degree angles. Ignoring this could leave you stuck when you need to cut certain materials.
It is important to check the bevel capacity as it will dictate the type of cut you’re able to get. A wider range will give you more freedom when cutting material at an angle. Also, preset bevel stops will make your life a lot easier.
As with any handheld tool, weight plays a big role in its usability. For quick jobs weight may not be an issue but for those large projects, every extra pound will be noticeable.
It may not seem important but an integrated dust blower does wonders for the cutters line of sight by making the cutting line perfectly visible throughout the entirety of the sawing process.
It’s worth paying attention to the cord length on each model. Although you can use an extension cord for a quick fix it is nice to have a cord out of the box that will be sufficient for all your projects.
We hope this is never needed but it is always nice to have some reassurance. Purchasing a worm drive saw is a big investment and not something you want to repeat every year. Most saws will come with anywhere from 1 to 3 years warranty included.
A word about cordless worm style saws
Cordless models are not true worm drive saws. But what exactly does that mean?
The reason comes down to the gearing system that drives the motor. Worm drive saws use worm gears whereas cordless models tend to use a direct drive system which is seen on sidewinder saws. Each come with their own benefits such as;
- Direct Drive – Load connected directly to the motor. Avoids gear backlash and friction loses, overall more efficient.
- Worm Drive – Can transfer motion in 90 degrees. Increased torque. Smooth and quiet.
Despite the difference, they still feature the same design and power traits associated with worm drive saws such as the left side blade positioning, motor positioned behind the blade, rear handle and improved torque. These can be just as good as corded the models.
If you do want to opt for a cordless circular saw for portability, then it’s highly recommended you invest in the latest models with a brushless motor.
Brushless tools have grown in popularity in recent years due to the added benefits they bring. These include:
- Adjusting their power output in accordance with the task at hand. So, if the saw detects more resistance, more power is produced to compensate.
- Increased motor longevity – as there is less stress on the motor
- Zero motor maintenance compared to brushed motors
Worm drive circular saw vs standard circular saw
We have already covered this in detail here. However, in short, the standout difference is the increased torque.
This is made possible by the positioning of the blade relative to the motor which requires the gearing system to sit at 90 degrees to the blade. The result is slightly reduced blade speeds, but much greater torque. It also means worm drive saws can use larger blades than circular saws. As you’d expect, with extra power comes added weight and a heftier price tag.
We also did a round-up of the best sidewinder circular saws which you can find here.
Wrapping it up
There you have it, the top 7 worm drive circular saws money can buy. You will have seen a variety of saws, each with their benefits and drawbacks with something to suit everyone. The ideal worm drive saw must pack plenty of torque while maintaining a lightweight and well-balanced design.
It wasn’t an easy decision, but our best pick goes to the Skilsaw SPT77WML-01. The Skilsaw ticks all the boxes you’d expect from a high-end power saw. From the dual copper winding system for improved longevity, full magnesium construction making it super light and easy to use and the ease cut ready depth system. This saw is sure not to disappoint!
