A circular saw has a round, toothed blade that cuts via rotary motion while rotating around an arbor and is supported by a metal plate above the cutting surface (shoe).
Traditional corded circular saws are powerful, but their cabled design restricts their reach and utility because they require a nearby electrical outlet.
However, since cordless circular saws are battery-powered, they are easily transportable and can be used virtually anywhere. Consequently, these are the best cordless circular saws to consider purchasing.
How to Use a Cordless Circular Saw
This cordless saw model is a valuable tool due to technological advancements and its brushless motors and powerful batteries, which allow you to operate a 7 14-inch blade (same as corded saws). It is cordless and comes with its power source, so it can be utilized wherever necessary.
To maximize the performance of a saw, adhere to the following operation and safety guidelines.
Choose the Appropriate Blade – Although different blade types (such as rip blades, general-purpose blades, and crosscut blades) are utilized to cut various materials. Therefore, selecting the proper blade type for your cordless circular saw will result in precise cuts.
Installation of the Blade: After selecting the correct blade, install it according to the manual’s instructions. Using a wrench, remove the 5/8-inch bolt that holds the blade is driving in place. Ensure that the edge is facing the correct direction, as many blades have an arrow printed on them to indicate the right rotation direction.
Calibrate the Depth and Bevel Angle: We are aware that circular saws feature depth and bevel angle gauges. All you need to do is calibrate them properly for perfect material/object cutting.
Wear Safety Equipment: Before operating the cordless circular saw, it is essential to wear safety equipment, such as safety glasses, hand gloves, perfectly fitting shoes, ear protection, etc.
Safety Measures – Nearly all cordless circular saws (except those with 4-and-a-half-inch blades) necessitate manual operation for safe operation – a handle with a knob-like grip and trigger on the front of the device. Thus, it enables optimal saw control that prevents fingers from entering the blade’s path. Also, before cutting, ensure that the retractable guard is in place.
Operating the Saw: Mark the line on the selected piece of wood using a market to ensure an accurate cut. Align the saw’s blade on the wood’s edge with the marked line. Adjust the blade, so it extends slightly below the depth of the wood piece. However, not too much, as it makes it difficult for the saw to cut through the material.
After positioning the saw, the cutting process can begin. Activate the saw and permit the blade to operate at maximum speed. Now, slowly and carefully pull the saw through the wood. Permit the blade to complete its task without rushing or forcing the saw. Upon completion of the cut, immediately release the trigger and wait for the blade to stop spinning.

What We Look For In The Best Cordless Circular Saws
Not too long ago, cordless circular saws had to be feathered compared to their corded counterparts. Today’s battery-powered options are vastly superior, and many brands’ flagship brushless models easily outperform 15-amp corded saws.
If cutting power is your top priority, you can expect to pay more for a saw. However, if you don’t mind taking your time, several excellent cordless options can help you complete the task for less money.
A misaligned arbor is not a factor in tracking; if this is the case, the saw should be returned. Occasionally, the handle design can encourage you to push to one side or the other, mainly when a saw’s front and rear handles are close together. Typically, you can quickly adjust to the design of the handle.
In some instances, the lip of a circular saw guard can catch. Even if the material is smooth on a standard cut, thin, miter, bevel, or compound cuts can reveal defects. Perform a series of test cuts on scrap material to determine if your guard catches on a specific type of cut so that you know when to lift it without dragging away from the cutline manually.
Dust and Chip Removal
Many of the best cordless circular saws have vacuum ports, which are superior at removing chips and dust than those without. The majority of our team, however, never uses a vacuum for regular cutting. We prefer a vacuum adapter that is either detachable or pivoting to direct the chips in the desired direction.
The majority of circular saws are effective at clearing dust and chips. The clearing deteriorates as RPMs decrease due to a slower top speed or bogging down. For effective clearing, search for models with at least 4500 RPM (5000 is preferable) and a brushless motor.
Handle comfort is a matter of personal preference, with hand size significantly determining what feels best. While rear handles are rarely problematic, our team prefers front handle designs that are not too thin, too close to the rear handle, or angled in an uncomfortable direction. Check to see if you can handle the saw in the store before taking it home. If you dislike the grip in the store, it is unlikely to improve as you cut.
Because you almost always cut on top of your material, the weight of your circular saw primarily comes into play when transporting it. Nonetheless, heavy saws can contribute to “stickier” cutting if the shoe is not sufficiently low friction. There is no reason to carry more weight than necessary, and it is possible to find a Pro-level saw that weighs less than 10 pounds with the battery.
Cost and Value
We place a premium on value and enjoy determining the best value for our budget. Start with what you know you’re willing to spend and work backward to establish your priorities. Here are the factors we consider when calculating value:
- Functional Design and characteristics
- Depth of compatible battery-powered equipment
- After-sales service and warranty
The distinction between 18V and 20V cordless circular saws is unclear. Many believe that 20V is more potent than 12V, but the voltages are identical.
More manufacturers are substituting 6-cell sets for 5-cell sets on 18V/20V max tools. These operate at a higher voltage. Marked 24V Max or 22V, their nominal voltage is 21.6V. They have the potential to produce more power or runtime with 20% more cells.
36V/40V Max batteries are a means of increasing power. Makita and Skil have two-battery systems combining 18V/20V maximum batteries in series to achieve a higher voltage. Makita also offers the 40V max XGT line, whereas Metabo HPT offers the 36V MultiVolt system.
This circular saw is powerful. Equipped with a 60V battery (it won’t work with 20V maximum batteries), it also has a long runtime, which you may need because this saw performs well on almost any task. The blade is located on the right, the same side as most corded saws, so you’ll feel right at home using it.
Yes, it is possible to cut the material without a table. However, most experts recommend using a table (to secure the material) when cutting with a circular saw. If you don’t have access to a table, connect the material in any other way to ensure a precise cut. For example, clamp it down, which is the standard method for cutting without a table. However, holding the material in one hand while operating the saw with the other is not advisable. As a result, you sustain injuries, and the material is improperly cut.
The number of cuts a cordless circular saw can make before needing to be recharged is typically used by manufacturers to rank them. However, it is somewhat difficult to calculate since different types of materials require other cuts, which need varying power levels. A typical cordless model can make 300 cuts without difficulty on a single charge.
Most people believe that circular saws can only be used to cut wood. However, this is untrue; it is an effective cutting tool for various materials, including plastic, melamine, stone, tile, concrete, drywall, tile bricks, metal, and particleboard. Remember to replace the blade when cutting different materials (per the material cutting requirements).
Manufacturers design circular saws with left-side blades and the motor and other weight on the right side of the saw. So, with this configuration, the stabilizing knob will be held with the right hand while the trigger handle will be held with the left. Thus, it provides maximum visibility and permits the user to obtain a vivid view of the cutline to make a flawless cut.
In conclusion, cordless circular saws are essential additions to your toolkit. As you can see, these saws have slightly different features, but they are all designed to make the perfect cut.
Consequently, using our purchasing guide, you should be able to select the best cordless circular saw for your needs from the models reviewed.
