How to Use a Circular Saw

January 23, 2021

There are a lot of circular saws out there and just as many different opinions on how to use them. They come in a variety of shapes, sizes, and the most common form they take is the tabletop version. Most reviews will give you an idea of how to use it based on their experience, but they will rarely tell you how to end up using it. These various reviews will look closely at the different uses of the saw and who they are best for.


The most common use for a circular saw is straight through cuts. Everything from woodwork to furniture to smaller tree limbs can be cut with a saw of this caliber. Because these cuts are so common, it is easy to simply look at the basic uses and conclude that they are perfect for straight-through work. This is not the case, however. If you read through these various reviews, it is best to understand why they aren’t the right choice for everything.

Safety Tips

Even though it may look simple, using power tools without the proper precautions can lead to serious injury. A power tool is potentially deadly when it isn’t used properly or when it is used improperly. Check the cord and plug-in connections as well as the blade holder and barrel spool before you begin any project. Make sure the saw is in good working order and clean the blades and cord frequently. These safety tips should prevent any injury from occurring.

Safety Tips

Perfect Alignment

Since a circular saw is primarily intended for straight cuts, perfect alignment is a must. You don’t want your saw to start or stop because of an imperfect angle or tilt. This can result in safety hazards and possible damage to your work area. Alignment should be precise as cut holes are usually shallow and accuracy is crucial.

Blade Inspections and Maintenance

Blades should be inspected on a regular basis to ensure the blades are free of dulling or damaged areas. This ensures the blade is always sharp and cutting correctly. Always inspect blades while the saw is still hot to ensure the blades are cool enough before attempting to cut. Dull blades quickly lose their cutting edge and may pose a safety hazard when attempting to make deeper cuts. Also, inspect the teeth on the blade as well. Most saws will indicate the tooth condition as either blunt slightly worn or slightly corroded.


Blades should be cleaned after each use to remove mineral build up, dirt and dust particles. Blade oil, which is typically sold separately from saws, can be used to extend the life of blades and prevent dulling and damage. Also inspect the motor and the spindle nuts on circular saws to ensure they are in proper alignment and functioning properly. If these parts are damaged or not functioning correctly, the machine may not work correctly and cause injury or death.

Power Source

Circular saws require electrical power to operate. Whether you are purchasing a saw already assembled or building one yourself, you should carefully examine the power source and ensure it is safe to use. The power cord should be made out of non-toxic material and attached to the appropriate location. Avoid using an old, broken power cord as this can pose a hazard and is also a potential fire hazard.


A circular saw can make use of a guide rail to help make fine, clean, smooth cuts. A guide rail allows you to angle the blade and apply pressure on the bit as you make each cut. However, a guide rail can become damaged if it is not installed properly and if it is not maintained properly. Professionals who assemble saws will place a small amount of lubricant along the guide rail to prevent friction and rust from causing damage. Properly installed guides can last for years.
