Best Circular Saw in 2021 – Reviews and Buyer’s Guide

Best Circular Saw

Circular saws will be your best friends once you discover all the handy things they can do. If you enjoy doing DIY projects at your home, this handheld power tool is a must. It can easily cut through wood’s grain or across it with its circular blade. DIYers will understand how a circular saw can make tasks like framing, woodworking, or even masonry plain-sailing. They come in a variety of styles and sizes, and the kind of teeth may differ too.

You can choose from different powered variants, but a corded circular saw is more powerful than a cordless one. A good home workshop requires a circular saw with speed and accuracy. Our comprehensive guide of the best circular saw will help you choose one that makes the cut and also tell you the things you should consider before making the purchase. But, if you are in a hurry then here are our top 3 recommendations.

Best Circular Saw With Good Blade And Smooth Cutting

1. Makita SP6000JI – Best Circular Saw

Makita SP6000J1 6-1/2 Inch Plunge Circular Saw Kit, with Stackable Tool Case and 55 Inch Guide Rail

Power: 12 Amp
Blade Size: 6½ inches
Blade Side: Right
Max RPM: 5,200
Max Cutting Depth: 2-3/16  inches

Circular saws either come with a guiding line of the rail or a laser. Despite the accuracy that laser guides offer while cutting, the good old rail-guided circular saw is still the best when it comes to high-level precision. The Makita SP6000JI circular saw has a 55-inch long guide rail which allows for accurate repeated cuts. It isn’t a tablesaw and has a long 7.9 feet cord; both features give it good portability despite it not being cordless.

The Makita SP6000JI has a 6½-inch plunge blade which means you can “plunge” the blade from any point in the material, unlike other circular saws where you have to begin cutting from the edge. The 12-Amp motor and magnesium components can handle all types of cutting tasks efficiently. You can get nice, clean cuts and its variable speed control dial is very helpful to change the blade’s speed.

2. SKILSAW SPT77WML-01 – Circular Saw with Power

Power: 15 Amp
Blade Size: 7¼ inches
Blade Side: Left
Max RPM: 5300
Max Cutting Depth: 2⅜ inches

The best feature about this circular saw is its worm-drive design. This allows you to have a better reach due to the increased distance between the handle and the blade. You can also make longer cuts more precisely because of this. This saw is an excellent choice if you use it for more extended periods of time because it is relatively lightweight at 11.5 pounds. This reduces fatigue during longer runtime. The SKILSAW SPT77WML-01 features cut-ready depth adjustment levels for quick adjustments for ¼ ply, ½ ply, ¾ ply, and 2x ply.

The Dual-Field 15-Amp motor is quite powerful and can easily handle cutting different materials. This motor doesn’t heat up much during operation. An anti-snag lower guard helps with smooth functioning with cut-off pieces. There is a maximum 53-degree bevel capacity with the option to lock it at the most-used level. Users have noticed that the gear oil is absent from the gear housing, so make sure you take that into account before buying this.

PROS (What we liked)
  • Only 11.6 pounds
  • Powerful 15-Amp motor
CONS (What we didn’t like)
  • No gear oil in the gear house

Factors To Consider Before Buying A Circular Saw

1. Style Or Design Of The Saw

The function of circular saws will differ depending on the style. They are either worm-drive or sidewinder style. The motor in a worm-drive saw is located behind the blade, which gives it higher torque than circular saws. They are better for high-power cutting tasks like knotty wood or pitch cuts. Sidewinder or direct drive saws have the motor to the side. This can act as a hindrance because of the side where the motor is being slightly heavier than the other one. But you get better overall control with a sidewinder. 

2. Corded Or Cordless 

It is evident that a cordless circular saw offers more portability. So, even if you have an outdoor project, They are also more lightweight than corded circular saws. Corded circular saws generate much higher cutting power than battery-powered models. But some battery-powered saws have brushless motors that provide enough cutting power to get DIY projects done. Additionally, they are not dependent on their battery life for running for a long time. Your choice should be swayed by the kind of projects you do more, whether you need mobility or not.

3. Blade Size 

The blade size of a circular saw is essentially its diameter in inches. The most common size in use is 7¼ inches, but models which aim for more portability have smaller blade sizes. The size of the blade matters because it influences the cutting depth through more robust materials. The larger the blade, the more cutting efficiency it has. Another thing that plays an important role when selecting a circular saw is the type of blade. Most circular saws have wood-cutting blades. But if you need to cut through metal or other thick materials, you would need a blade with higher TPI (Teeth Per Inch). 

4. Adjustment

When you are doing a DIY project, there will be times when you need to cut at angles (called bevelled cuts). This is why you have to consider all the adjustments that the circular saw will offer. Most models are able to tilt between 0 and 50 degrees with an option to lock into the level you use most often. This feature comes in handy, so make sure to check this out before finally buying a circular saw. 

5. Power

This corresponds to the motors that run cordless circular saws. If you are in for the portability of a cordless saw, then you would have to look out for a motor that is most efficient for your DIY tasks. The most common is a 15-Amp motor that is able to perform most cutting tasks comfortably. If you are on a budget, there are 10-Amp or 12-Amp models too. Know that these models will not be able to carry out heavyweight tasks.   

6. Speed

You must be wondering why the speed of the blade matters. The speed or the RPM (revolutions per minute) of the saw’s blade displays how fast you can cut through a material. Most blades have RPMs in the range of 5,200-5,500 revolutions per minute. This doesn’t refer to the blade’s ability to cut through a material; it is just an indication of how fast it will do the job.  

7. Safety Measures

A tool like a circular saw can be dangerous despite you having the experience and skill to use it. Most models come with safety measures that also help you to operate the saw efficiently. One of them is a brake stop which stops the blade once you pull your finger back from the trigger. A more advanced version of this is a guarded trigger which allows the trigger to work only when a safety button is pressed.

Circular Saws Specs Comparison

The important specs of a circular saw are the motor power, max RPM speed, the blade size, and max depth it can cut. You should also look for the blade side because it plays a major role depending on the place where you will use it.

Frequently Asked Questions

What’s the Difference Between a Miter Saw and a Circular Saw?

Despite both a miter and circular saw having the same end function– using a sharp blade to cut through lumber or other materials, they have different characteristics. Circular saws are designed to be small and handy. Miter saws are bulky and stationary but are more precise than circular saws.

Is it Possible to Cut Straight with a Circular Saw?

Don’t think that because they are called circular saws, they cut in circles. That just describes the round blades. The actual function of this tool is to cut straight lines. But if you err even slightly, you might end up having a crooked cut. But with time and practice, it isn’t very hard to keep your saw inline straight.

Can you Change the Blade of a Circular Saw?

Yes, it is very much possible to change them. The need to change your circular saw’s blade can be because of an old/damaged blade or that you have to cut through metal or other materials. Older saws had complex mechanisms, but newer models have reasonably straightforward ways to change blades.

What are must-have circular saw accessories?

I would recommend you to get a Circular Saw Blade Sharpener to keep your blades sharp and increase their life.

Conclusion

Circular Saw is indeed a need when it comes to cut the hardest of metal or wood to the easiest of plastic, and provide easy handling throughout the process. Make sure to take safety measures as any mistake can hurt you, deal with them with responsibility. We hope that this article would have helped you to find the best circular saw.
