When starting on a woodworking project, one of the most important tools that is an absolute necessity is a circular saw. There are a variety of types – and uses – for these circular saws which are appropriate for the material that is going to be cut. Whether it’s wood, ceramic tile, steel, or stonework (such as granite or marble) the right type of saw is a must in order to do the job right and not waste expensive materials. The most important aspect is to find the best circular saw for the money for handling the materials needed for the project.
How to use a Circular Saw
Everyone has been told a thousand times – measure twice and cut once. That’s the first thing the shop teacher says in Junior High School shop class. Take a look at some of the best tips on using a circular saw.
Positioning for Easy and Accurate Cut
Since there is no real “rule” stating which direction the circular saw is positioned when making various cuts, it’s generally determined by the space available and the user’s dominant hand. However, there is one helpful hint that will help in the long run – place the saw where motor is seated on the supported section of the material being cut so that the saw doesn’t fall away when the material is sliced. This allows for the shoe of the saw to be completely supported for the duration of the cut and the bulk of the weight lays on the supporting workbench or table.
Proper Support and Guidance is Essential
One very important rule is to make sure that before the rip cut or crosscut is made that the workbench, or table, is secure and stable. In addition, the metal guide must be properly attached to the base of the circular saw, however, if the rip or crosscut is larger, clamp a long board in place to use as a guide for the cut.

Types of Circular Saws
There are a wide variety of both hand-held and mounted circular saws that are for assorted materials. Some of the circular saws include the following:
- Abrasive Saw – also called a chop or cut-off type of power saw. It’s generally used to cut concrete, tile, and assorted metals.
- Biscuit Joiner Saw – also known as a plate joiner. It uses a smaller blade to cut the mouth (the oval-shaped hole) in the opposite edges of the material being cut.
- Carbide Saws – these are available in both vertical and horizontal models and are generally mounted on a spindle, or used as layer saws where multiple materials can be cut simultaneously.
- Cold Saw – this type is designed to cut metals with a heavy toothed blade that more efficiently transfers the heat produced by the cutting to the expelled chips. Generally, these are made with a tungsten carbide-tipped or high speed steel circular blade.
- Concrete saw – this type is also called a consaw, and is used to cut brick, tile, and various types of stone, marble, or granite. These generally use diamond saw blades for cutting this denser material, and because cutting these materials produces a lot of heat, the blades must be allowed to cool at regular intervals.
- Pendulum Saw – this type of saw is used predominantly for make cross cuts in the materials, and is fixed on a swinging arm that is often equipped with a weight for counterbalance.
- Pivot Saws – these are generally used for larger, heavier materials (such as heavier metals/steel) are cut
- Radial Arm Saws – these are circular saws which are attached on some type of horizontal arm and is often use for making longer cuts.
- Table or Panel Saw – this type of saw is mounted on a bench or platform.
A Preference of Corded or Cordless
There are many pros and cons for choosing a circular saw with either a power cord or one that is cordless and runs on batteries. Of course there is no substitute for quality and performance and for many people, it as personal choice. Take a look at some of the pros and cons:
|Runs as long as there is sufficient electricity.||When traditional power is not available, there must be a generator, or it does not work.||Perfect where there is no electrical power available.||The battery has to be charged for it to work.
Must have spare batteries handy when the battery dies.
|No batteries to recharge||Batteries must be recharged frequently.|
Both power cords and extension cords get in the way – which can be a safety hazard.
|There is no cord to untangle and that saves time.|
Also safer because there is no tripping on the cords.
|Unlimited amount of power.||Limited amount of power.|
|Cuts at a faster rate for longer periods.||Tends to slow down on extended cutting projects.|
|No batteries to replace.||Need to replace the batteries.|
|Generally comes with a 7¼” diameter blade which produces more cutting power because the larger blade moves faster.||Generally comes with a smaller blade at 6½’ diameter and has slightly less cutting power because the smaller blade doesn’t move as fast.|
|Not highly portable because they are tethered to an electrical outlet – thus less convenient.||More portability to jobs that are not near a power source – thus more convenient.|
|Tend to last longer than the cordless variety.||Doesn’t always have as long a life as the corded models.|
|More suited for harder materials such as granite, marble, or steel, but can still easily cut wood.||More suited for easier cutting projects such as wood.||Not as good on harder materials such as granite or marble.|
|More expensive||Less expensive|
The most important aspect is to make sure that the right type of corded or cordless circular saw – and blade – is used for the job!
- ALWAYS wear eye protection!
- Before turning it on, make sure that the lower blade guard moves smoothly when retracting and releasing.
- Check the teeth on the blade to ensure none of them are broken, chipped, rusted, dull, or damaged in any way and make sure to replace the blade if there is any damage. NEVER use the circular saw if the blade is damaged!
- Check the power cord to verify that there are no cracks or tears in the cord, and if it’s a battery-powered circular saw, confirm that the battery is completely charged.
There’s nothing worse than wasted time and material when saw is faulty and cuts are not done correctly. Most beginners feel quite comfortable using the more basic tools – a jigsaw, a drill, or a lathe; however, many are intimidated when the circular saw is introduced. There are some excellent circular saws available on the market that are perfect from the novice level to the seasoned professional, and are equipped with excellent safety features and are easy to use.
