How to Choose the Best Cordless Circular Saw: A Buying Guide
If you’re looking at buying a cordless circular saw, it is important to prioritize what is most important to you and evaluate the important characteristics and features of the tool. Here’s what you need to consider.
Circular Saw Features and Breakdown of Blades, Batteries & Power
Cordless circular saws come with a variety of features and accessories that help us get the job done safer and more efficiently.
Different models have different features (of course) and while some may be available on multiple types of cordless circular saws, what is the most important thing to look for on the tool is the kind of features that you’d like to see included with your saw.
Once you know what features you need, you can narrow down the search and focus only on those models that have these specific features included.
Below are some of the other features that come with cordless circular saws and some useful information about each of them.
- Handles: Choose a model with soft, non-slip handles for greater control.
- Adjustable Handle: Having a circular saw with an adjustable handle can be extremely advantageous, since not everyone has the same grip. With this capability, you can adjust the handle to different heights or angles for optimal user comfort.
- Blade Guard: The blade guard is the part that covers the blade when the circular saw is not in use and retracts smoothly to expose the blade during use. Look for a model with a notched blade guard. This type of blade guard enhances the user’s visibility and precision when cutting, allowing you to see the exact position of the blade’s teeth against whatever it is that you’re cutting.
- Dust Port/Dust Extraction: A circular saw’s dust port consists of an opening located at the rear right hand side of the blade guard. It allows the dust to get out of the way of the cut line. Some models have a tube hooked up or connected to it for added disposal of the dust.
- Foot Plate/Shoe: This feature steadies the saw against the work piece.
- Rip Guide: This is a metal guide that is designed to improve the accuracy of the saw. It’s particularly useful for those jobs that require a high degree of control and precision.
- Parallel Guide: This guide is similar to a rip guide and comes attached to the base plate. It comes as a standard on most circular saws. It allows you to make accurate cuts at a set distance from an edge.
- Depth Controls or Depth Adjustment: Depth controls allow for cutting of different work pieces featuring varying thicknesses.
- Adjustable Base Plate: An adjustable base plate tilts to a set angle, allowing you to easily make angled cuts. With this feature, you can set the saw at an angle of anywhere from zero to 45 degrees and also adjust the cutting depth.
- Bevel Capability/Bevel Adjustment: This feature enables the footplate to tilt in relation to the saw’s blade when making bevel cuts. With this feature, you’re able to make bevel cuts easily and more accurately. It allows for tool-less adjustment and comes with positive stops that also boost the efficiency of the circular saw itself.
- Electric Blade Brake: This is a safety feature that many circular saws have as a standard. It stops the blade automatically when the saw’s trigger is released. It achieves this by reversing the flow of electricity in the motor as soon as the trigger is released.
- Spindle/Shaft Lock: This feature immobilizes the shaft and the blade, which makes it much easier to change the saw blade.
- Laser Guide: This type of guide enables you to cut in the straightest line possible. The laser guide feature includes a laser that shines a small beam into the work piece surface for you to follow. Unfortunately, the beam typically doesn’t work in bright sunlight and may be obscured by dust and debris.
- Heavy-Duty Base: A heavy-duty base featuring cast metal and reinforced steel resists bending which may occur during use.
- Magnesium Housing: The lightweight magnesium housing provides maximum protection for the motor without adding weight and bulk to the tool itself.
- Wrench Storage: For circular saws that require wrench adjustments, wrench storage can be an extremely useful feature. These storage compartments hidden on the body provides a convenient storage solution for the saw wrenches.
- Site Lines: These are a type of guide marking, which makes measuring and cutting straight, much easier and more accurate for better results.
- Built-in Saw Hook: A hook through which you can hang your tool on can add convenience when it comes to storage and also help save space.
- Ball Bearing Motor: Ball bearing motors are more durable and typically last longer than those without them.
Blades and Such…
A cordless circular saw’s blade can be located on the left or right side of the motor, depending on the brand and model. Some manufacturers have models that offer both options.
Like corded circular saws, cordless units can be either a worm-drive or a sidewinder.
With a worm-drive saw, the blade is located on the left side of the motor. This design makes it easy for right-handed users to clearly see the blade when cutting. The downside of having the blade on the left side of the saw is that the weight of the tool is on the waste side of the cut, which leaves the unit unsupported and, therefore, unbalanced.
On a sidewinder saw, the blade is on the right side of the unit; while saw’s handle is set over the blade. Although the saw may feel unbalanced when the user holds the tool, its weight tends to be well balanced when the tool is in use.
Since the blade sits alongside the motor, the sidewinder saw’s design allows for a cutting tool that spins faster and is lighter. It is typically more maneuverable over a long day on the worksite compared to a worm-drive. This type of circular saw is also less expensive compared to warm-drive models.
The main advantage of a worm-drive circular saw is that it offers significantly more torque. Its motor is usually in line with the blade, which enables it to deliver enough torque to curve up wet lumber or even saw through concrete.
A worm-drive saw also allows the user to better resist kickback and steer the unit through long rips, since the handle is located further back from the blade. Because of this, a worm-drive model can be the best cordless circular saw for framing and major renovation jobs.
Generally, worm-drive saws are shorter and longer than sidewinder saws. They are also heftier and more expensive than sidewinders.
Blade Size or Capacity
The size of a cordless circular saw is indicated by the diameter of the blade that it can take. The work capacity is designated by the maximum depth of cut that a saw can make both at a 90-degree angle and at a 45-degree angle.
The longer the diameter of the blade, the higher the cutting capacity. But it’s worth noting that using the biggest blade every time you’re working is not always recommended due to safety reasons. When choosing a blade, look for the one with teeth that extend past the bottom of the cut.
You need to consider the piece that you’re cutting, rather than just the actual blade itself.
Typically, blades for cordless circular saws range between 5-1/2 and 6-3/4 inches, with the 6-inches blade being the most common.
The 6-inch blade is able to cut at least 1-3/4 inches deep at 90-degree angle and 1-1/2 inches deep at a 45 degree angle. Blades of 5-3/8 inches and larger can cut through 2-inch wood in a single pass at 90 degree; but, at a 45 degree angle, this blade would require two passes.
A blade of 5-1/2 inches can cut only 1-1/2-inch wood at a 90 degree angle. Any blade that is larger than 6 inches has the capacity to cut through 2-inch wood at a 45 degree angle in a single pass. But a smaller blade would have to make two swipes to completely cut the material.
The best cordless circular saw models with a 36V battery and 4,000RPM usually have a capacity to cut through 4×4 inches wood.
As well as blades for cutting wood, there are circular saw blades designed to cut other materials such as metal (aluminum, stainless steel, etc.), concrete and ceramic tile.
While blades for cutting wood can be re-sharpened after extended use, blades for cutting metal and other hard materials have to be completely replaced rather than being re-sharpened.
Another consideration to take into account when choosing blades for your cordless circular saw is the number of teeth and the material.
A blade with a large number of teeth cuts slower, but results in a smoother cut. Conversely, blades that use fewer teeth cut faster, but can cause splintering, particularly when cutting through softwoods.
Consider buying carbide-teethed saw blades. Carbide-tipped blades are much tougher, more durable and last longer than your typical, regular steel blades.
These blades also cut through wood and other materials more quickly.
Power and Weight
The power of a circular saw (or any other power tool for that matter) is determined by its voltage capacity. The voltage capacity of cordless circular saws ranges from 14.4 V for the lightweight models through to 18 V for the middleweight category and 36 V for the heavyweight (heavy-duty) high-end models.
Cordless circular saws with a high-voltage capacity require a heftier battery pack, which means they tend to be bulkier.
These higher-voltage models are quite heavy and can weigh up to 10 lbs., which is as heavy as corded models. Middleweight models weigh around 7-1/2 lbs. A significant advantage of having a higher voltage capacity is high RPM capacity, which translates to increased power and cutting speed.
The obvious downside of a cordless circular saw is that it runs on a battery that has to be recharged periodically in order to provide practical service.
When the battery runs down, there is no power to run the cutting tool. The batteries, therefore, must be continually recharged and will eventually wear out and need replacing. Which is why most people have 2 batteries charging while having one is use.
These battery packs are available in a plug-in version or a slide-in version. It is recommended to buy a back-up battery pack if the saw is going to be used for extended periods. Also, many models don’t come with batteries or a charger, and you may have to purchase them separately.
