The 8 Best Circular Saws

1. Rockwell RK3440K – Best for Cutting Capabilities

Rockwell RK3440K

The Rockwell RK3440K is portable and affordable. Although its 4 amp motor isn’t the strongest, it can still deliver speeds up to 3500 RPM.

You can adjust the depth of the cuts you make with a lever as well as change between the three blades the saw comes with in order to cut through various materials. Its lightweight design helps you maneuver and use it to cut veneers, particleboard, and plywood. It can also cut through tile, marble, cement, and even concrete.

As for the safety features, the Rockwell RK3440K comes with a lock-off safety switch, dust extraction to maintain visibility during operation, and a laser guide technology to deliver the most accurate and precise cuts.


  • Easy to handle
  • Equipped with a laser marker
  • Easy to transport and store
  • Stable to use on the bench or in place
  • Ready to use out of the box


  • Can’t make bevel cuts
  • Doesn’t cut very deep
  • The blade isn’t completely visible which makes it harder to hit your stop mark

Bottom Line:

For a high degree of versatility and flexibility on a relatively small and affordable circular saw, opt for the Rockwell RK3440K. However, you shouldn’t be expecting cuts that are too deep or bevel ones.

2. DeWalt DWE575SB – Best Corded Circular Saw

DeWalt DWE575SB

The DeWalt DWE575SB is among the lighter choices on the list and one of the highest quality tools. Its compact body packs a powerful 15 amp motor that can run it at a speed of 5300 RPM to cut through tough materials.

The DWE575SB comes with a 56-degree bevel with a stop at 0 degrees and 45 degrees to deliver maximum flexibility.

Although the dual-field motor performs well, it maintains a cool temperature throughout its operation. It’s also equipped with a 10” cord that makes it very portable.

Moreover, the DeWalt DWE575SB comes with a right-sided sidewinder, so this 7-1/4” circular saw provides you with great visibility along with the balance and comfortable grip.

The dust blower also fixes the common issue of sawdust gathering and blocking your line of sight.


  • Full control over the unit thanks to the True Grip handle
  • Equipped with a dust blower to increase accuracy


  • The flat design of the depth adjustment lever isn’t the most convenient

Bottom Line:

The DeWalt DWE575SB combines being powerful, convenient, and affordable. The only drawback is how bothersome the design of the depth adjustment is.

3. Skil 5280-01 – Best Budget Option

Skil 5280-01

With a 15 amp motor and a 5300 RPM operating speed, you’ll be able to cut through the toughest materials such as plywood, metal, or even masonry with its 7-1/4” blade.

The Skil 5280-01 comes with a laser guide that helps you make more accurate cuts, although it’s not visible outdoors. And since it’s indoor-oriented, this saw is a corded model with a reliable dust extraction system.

Finally, it’s a very affordable unit with a bunch of great features packed into its size that is about 2/3 smaller than counterparts.


  • Powerful motor and higher speed
  • Easy to work with for extended periods
  • Comes with a carrying bag for easier storage and portability

Its design allows you to operate it using only one hand while delivering reliable and strong cuts.

How to Pick a Circular Saw?

There are a couple of things that you should consider when you’re shopping for a circular saw, and they are as follows:

Blade Size

A rule of thumb is that the bigger the blade on your saw is, the more capable it would be of cutting through tougher materials.

Blade Adjustability

As you work on your projects, you’ll often have to apply adjustments to your blade in terms of angle and depth. That’s why you should make sure that your saw provides you with easy adjustment methods that don’t require special wrenches or tools.


Typically, a circular saw is a hand-held tool, so it shouldn’t be too heavy. That’s why you should look for a model that uses lightweight construction materials such as magnesium. An ideal combination would be a lightweight model that enables you to maneuver it while being strong enough to handle different materials.


Not only should your saw itself be durable, but so should the blade be. This is to enable the tool to handle the number of working hours you intend to use it for and survive your projects no matter how heavy-duty they are.


The tougher the material you’re going to cut is, the more powerful your saw should be. Although the difference between 14 amp and 15 amp doesn’t seem much, it can go a long way in cutting capability.

Ease of Use

Consider how easy your tool is to handle, how comfortable the grip is, how ergonomic the design is, and how maneuverable it is.

Cordless vs. Corded Circular

While a cordless saw is more maneuverable and portable than a corded one, it’ll limit you to a certain operation time as it would be run by batteries.

So if you’re looking for extended periods of run time, you should go for a corded model. On the other hand, if you’re more concerned with how easy the tool is to handle, go for a cordless saw.

Final Thoughts

Although the eight options I’ve listed are considered the best circular saws on the market, I’d still recommend a few over the others.

For one, if you’re looking for a great cordless saw, I’d highly recommend the Milwaukee M18 2630-20. But if that option seems a bit pricey, you should go for the Skil 5280-01 or the Black+Decker BDECS300C.

Finally, if you’re looking for something that combines affordability with performance and suits entry-level users, you should opt for the DeWalt DC390B.
