If you only work on tile occasionally, a cordless circular saw can be outfitted with a carbide blade that makes it easy to remove cracked and chipped grout efficiently.

Features of 18V Cordless Circular Saws
- Blade Position
- Saw Blades
- Power and Weight
- Speed and Control
- Extra Features
A circular saw can have a blade that is either on the left or the right of the motor, and some manufacturers offer models that have a blade on both sides. A cordless circular saw can either be a sidewinder or a worm-drive saw much like a corded circular saw.
Sidewinders have the handle sitting over the blade with the blade found on the right side of the saw. They are also unbalanced when you hold them as the weight is placed behind the blade when it is in use. They also spin faster and are more lightweight than a worm drive.
The handle sits behind the blade on a worm-drive saw with the blade sitting on the left side. This makes it easy to see for right-handed users which can leave the saw unsupported as the weight of the saw sits on the waste side of the cut. They are also longer and shorter than a sidewinder with more weight and power.
The diameter of the blade determines the size of a circular saw. The maximum depth of cut determines it work capacity, but it is a good rule of them that the larger the saw blade, the bigger it’s cutting capacity will be.
Blades will range from 5 1/2 inches to 6 3/4 inches with a 6-inch blade being the most common. You can cut through 2-inch material in one pass with a 5 3/8 inches or larger blade at 90 degrees, but will need to use two passes if you are cutting at a 45-degree angle.
Blades are also designed to cut different materials besides wood like stainless steel, metal, aluminum, and ceramic tile. Remember that you may need to resharpen blades that you use to cut wood while blades used to cut metal just need to be replaced.
The number of teeth on a blade will determine how fine a cut you can make. The higher the number of teeth, the finer the cut you will make and vice versa.
The 18 volt saw is in the middleweight of the power category. Cordless circular saws range from the lightweight category of 14.4 volts to the heavyweight category of 36 volts. Remember the higher the voltage of saw, the bigger battery pack you will need and the heavier the saw will become.
The battery can be one of the biggest disadvantages of a cordless saw depending on how fast the battery runs out. It is always a good idea to have batteries that are continually recharged, so you can switch them out as you work.
The faster your blade turns, the better control you will have over the cut. To determine the speed of the saw you are considering, look for the revolutions per minute (RPM).
There are always extra features to a saw that aren’t necessary, but are nice gadgets to have. Features like LED job lights can be very useful, as well as an ergonomic handle which can keep your arm from getting tired while you work.
Safety features are a little more necessary, though. It is always good to find a saw that has a safety feature that is built into the motor that will keep it from burning out the motor, cool down the motor with a fan, or use an advanced braking system to stop the motor and the blade if there is an emergency.
