Battery-powered

This circular saw from Black+Decker doesn’t restrain you with a bulky power cord. Instead, it runs on a rechargeable battery pack to give you 20V of high torque motor power to tackle big jobs no matter where they are. It’s easy to adjust this circular saw to accommodate different cut depths, or for clean and precise angle cuts. You do need to purchase the battery packs separately.

Black+Decker 7-1/4-Inch Circular Saw

Good cutting power

This Black & Decker circular saw is also one of the lightest on the market, weighing in at just 7 pounds. This is particularly useful if you suffer from sore joints or expect to be using the saw on long jobs. The 13 amp motor offers enough power for most cutting jobs, and the laser guide is a useful feature for more precision cutting. A spindle lock allows for quick and easy blade changes. 

What to look for in a new circular saw 

Design

It’s easy to think that sheer power makes the best circular saw. In fact, it’s the smaller things, such as dust chutes, cord length, spindle locks, rip fences, and electric brakes, that make all the difference. A saw can cut at 6,200 RPM, but if it doesn’t include any of these features, it’s going to be a pain to use in the long run. These features enhance the durability and versatility of the tool in a profound way. An accessory as simple as an included carrying case makes the saw more portable, and therefore more useful.

Cutting features

The most important test we conducted was for handling efficiency. Our reviewers used each saw for several hours and compared their experiences to come up with a percentage score. Additionally, they looked at how deeply you can cut at 90- and 45-degree angles. They verified the bevel capacity, the wider the better, so you can cut to whatever degree you want. Positive bevel stops are also an important consideration since they allow you to quickly adjust the shoe for common angles.

How thick can a circular saw cut?

Circular saw blades range from about 6 1/4 inches to 10 1/2 inches in diameter. Generally speaking, the most common blade diameter is 7 1/4 inches, which can cut wood up to 2 inches thick. You can also cut materials up to 2 inches thick with a 6 1/2-inch blade, but 7 1/4 inches is still the most popular.

Still, less common, larger blades may come in handy if you work on projects that involve larger wood beams. Mayer mentioned the thick slabs needed for building tables and benches specifically.

Beyond size, there are other factors to consider as you choose the right blade for the job. Look for masonry blades when you need to cut brick or cinder block and tile-cutting blades for your flooring project. Also, you may need blades made of specialized, durable materials for certain projects. There are high-speed steel blades, which stay sharper longer than normal blades, as well as carbide-tipped blades that stay sharp even longer. Diamond tips can improve the quality of cuts on tiles.
