From thick boards to thin panel, a circular saw, with its spinning, toothed blade, makes it easy to cut through wood either with the grain or across it. These versatile power tools are a must for any DIYer who does a lot of woodwork, including framing a deck, furniture building, or even building a doghouse. There are both battery-powered and corded circular saws; battery-powered are more portable, but corded tend to have more power. Which you choose depends on your project and how often you plan to use it.

Here, the best circular saws on the market:

Best Overall: SKILSAW SPT67WL-01 Circular Saw

Skilsaw SPT67WL-01

Billed as one of the lightest Pro circular saws on the market, the SPT67WL-01 is only 8.6 pounds. While working on all-day projects, you will easily notice the difference a lightweight saw can make. A 10-foot power cord will extend your range without having to worry about running out of power with a battery.

The saw comes with a standard 7-1/4-inch blade that you can tilt up to 56 degrees for a beveled cut. The till locks at a 45-degree angle, which speeds up common cuts. If heat is a concern, the Dual-Field motor will allow the saw to continue running longer while staying cooler.

Best Budget: Skil 5180-01 Circular Saw

5180-01 Circular Saw

Conventional circular saws can quickly get up there in price if you're looking for the latest and greatest. For people with the occasional weekend or DIY project, most expensive saws won't be the right fit. The Skil 5180-01 is an excellent budget option since it will give you reliable cutting power and durability at an affordable price. At just 7.2 pounds, it is a couple pounds lighter than the other top picks. With the standard 7-1/4-inch blade, this saw will easily handle the typical 2x4s and plywood that most small projects rely on.

For the price, this saw is also a good match for dusty worksites. With the built in dust blower, you will be able to keep the cutting area clear of the small types of debris that can ruin the 14-amp motor.

Best Laser Guided: DEWALT DWE575SB Circular Saw

DWE575SB Circular Saw

A laser guide can give you a clear and visible reference point when making long cuts that need to be completely straight. The DEWALT DWE575SB comes with one of the best laser guides around. In combination with a durable stamped aluminum shoe that provides a smooth base, this saw can keep a cut straight through foot after foot after foot when cutting long pieces of plywood.

The saw also includes a power cord that is three times more durable than a standard cord. This will protect against accidental cord pullouts or damage. The integrated dust blower will also keep your sight line of the laser guide clear and free as you make long cuts.

If you often work with long boards, this is the saw to keep your cuts straight and true from beginning to end.

Best Lightweight: Rockwell RK3440K Versacut Circular Saw

RK3440K Versacut Circular Saw

Anyone looking for a highly versatile and ergonomic circular saw should look at the Rockwell RK3440K Versacut. Its streamlined design makes the Versacut easy to control with just one hand. Its 4-inch blade makes quick work of materials 1 inch or thicker.

For people looking for flexibility in a saw, the Versacut is designed to cut a wide variety of materials including woods, plastics, ceramic tiles, and even some metals like aluminum and sheet metal. At just 4 pounds, it is also one of the lightest options on the market. This makes it perfect for working around the home, yard, or professional jobsite where you need to cut many things in different locations in a single day.


Best Rail-Guided: Makita SP6000J1 Circular Saw

SP6000J1 Circular Saw

If you need the maximum degree of precision possible, the only thing for you to even consider is a rail guided circular saw. While laser guides are good for making accurate cuts, nothing can compare to the solid guiding line of the rail. The Makita SP6000J1 stands out among circular saws since it will give you this level of precision without being tied down like a tablesaw. With a 55-inch guide rail, this saw can also make long and repeated cuts while maintaining the same level of precision.

The 6-1/2-inch plunge blade and 12-amp motor are enough to handle most types of common cuts found on residential and commercial projects. If you think you will be cutting different types of material and thicknesses in one setting, the variable speed control dial will also help you match the speed of the blade to the material you're cutting.

Best Professional: SKILSAW SPT77WML-0 Circular Saw

SPT77WML-0 Circular Saw

Professionals often place more rigorous demands on their circular saws than the average DIYer, and so their tools need to stand up to the typical types of abuse jobsites can throw at them. For people wanting the absolute best in durability and cutting power, the SKILSAW SPT77WML-0 is the only option to consider. With the standard 7-1/4-inch cutting blade, it can cut up to 2-3/8-inch pieces of wood without flinching. The blade can also tilt up to 53 degrees with 0 and 45-degree locks.

One thing that sets this saw apart from other options is the magnesium-based construction. By avoiding the use of lighter metals and plastics, this saw's overall build will survive more abuse than cheaper options. SKILSAW's Cut-Ready system is also handy if you need to make quick and accurate cuts of various depths.

Best Cordless: Makita SH02R1 Cordless Circular Saw

SH02R1 Cordless Circular Saw

While corded circular saws undeniably win for the most power, there are times that portability is key. For those times, you’ll appreciate that not only does the Makita SH02R1 cut the cord, drawing power instead from the included 12-volt lithium-ion battery, but it still maintains a very impressive amount of power, delivering 1,500 rpm to slice quickly through plywood, MFD, pegboard, drywall, melamine, particleboard, and other lightweight materials. The saw itself weighs only 3.5 pounds, so it won’t weigh you down on the jobsite.

The 3-3/8-inch blade has a maximum cutting depth of 1 inch at 90 degrees, and 5/8-inch at 45 degrees. A tilting base lets you make bevel cuts from 0 to 45 degrees.

Best Compact: Genesis GCS445SE Compact Circular Saw

GCS445SE Compact Circular Saw

Not every sawing job calls for the maximum in size and muscle. A compact circular saw has many advantages over the standard size; it’s easier to maneuver a compact saw in a tight space, and typically, these saws are lighter in weight, making them easier on your hands when working for extended periods. The Genesis GCS445SE Compact Circular Saw is one of the most versatile compact saws available today. With a 4.0-amp motor rated for up to 3,500 rpm, it packs a powerful punch in a body that is half the weight of many larger circular saws; it’s just 4.7 pounds. Plus, it’s designed for one-handed use. But the features don’t stop there.

For messy projects, this saw has a built-in dust port and vacuum adapter to keep the cutting area free of debris. The dust collection system will work with a variety of standard vacuums and shop-vacs. The saw is also compatible with many cutting blades. The included tungsten carbide tipped blade is strong enough to cut through any 2x wooden board as well as similar materials, whether cutting straight, rip, or bevel. To use other kinds of blades, all you have to do is remove the existing blade and pop in the other.

Final Verdict

It doesn’t weigh too much, it’s very versatile, and its motor runs cool while putting out impressive power. That’s why the Skilsaw SPT67WL-01 (available at Walmart) wins our top spot as the best all-around circular saw. But if you need maximum portability, you’ll appreciate the battery-powered Makita SH02R1 (available at Amazon), which has enough oomph for most basic cutting tasks, and lets you work wherever you need to be.

What to Look for in a Circular Saw


Circular saws are available in either a worm-drive or sidewinder style. Worm-drive saws have the motor mounted behind the blade (which sits on the left) and usually offer excellent visibility for right-handed users. Sidewinder (also known as direct drive) saws have the motor mounted next to the blade (which is often on the right). While this can offer more control of the saw, it also can put the saw slightly off-balance, since the motor side will be heavier.

Corded or Cordless

Cordless circular saws offer freedom and flexibility to cut anything, anywhere—which is especially great for an outdoor job site. But cordless models also generally have more limited power and their runtime is limited by battery life. On the other hand, a corded saw will usually give you more cutting power and can run as long as it’s plugged into an electrical outlet.


Corded circular saws have motors rated in amps. A 15-amp motor is the standard for a circular saw capable of handling most DIY tasks. There are inexpensive 10-amp or 12-amp tools available, but those are generally only suited to lightweight tasks.

Cordless circular saws today have lithium-ion batteries, usually 18-volt. You’ll also find more powerful 20-volt models, however, which are a good choice if you use your saw for very lengthy work sessions, or deal with thick or heavy materials.

Blade Size

The most common size of blade for a circular saw is 7-1/4 inches. This is the best size for most DIYers, and can tackle materials more than 3 inches in thickness. But you’ll also find circular saws with 6-1/2-inch blades—these are for lightweight jobs—and 8-1/4-inch blades for more heavy-duty use. There are also circular saws with small blades, often around 4-1/2 inches, that are mostly used for cutting panel or other thin materials.
