Circular saws are a great tool for making precise cuts, and with the right technique, you can use them to cut perfect circles. In this blog post, we’ll show you how to do it. First, mark the center of the circle you want to cut on your workpiece. Then, set the blade height to where you want the circle’s edge to be. Clamp a piece of scrap wood to your table saw fence as a guide, and make your cut. It’s that easy! Happy circular sawing!
Cutting A Circle on a Table Saw
Once you get your circle marked, place a scrap piece of wood on the fence clamped to the side you will be using (so if you are cutting from left to right, clamp it on the left fence). Lower your blade so that it is just above where you want the circle to start. Next, make a mark on your workpiece where the blade is touching it, and remove the scrap from the fence. This will be where you begin cutting, but remember that as you cut more of the circle, you must always keep track of your position on any marks or lines that guide your cuts. Once you have clamped the scrap back into place, you are ready to cut. Read more here How to cut a rabbet joints on a table saw.
Slowly push the workpiece through the blade, making sure to hold it firmly against the fence. Keep your fingers away from the back end of the saw blade as you do this! If you want to make more than one cut like this, always wait for the blade to stop spinning (or lock it in place if your table saw has a safety feature that will do this automatically) between each pass. This is the only way to be absolutely sure that you won’t lose a finger!
A very important part of making perfect circles is to always know where you are on any marks or lines that guide your cuts. If the edge of your workpiece ends up slightly off of where it needs to be, you can always re-mark your cuts and try again. Just make sure that if you need to do this, the scrap wood is fully clamped back into place before you turn on the table saw!
Circular Saw Tips
Another important thing to remember when using a circular saw is not to force it through the wood. The blade will only cut as fast as it can safely go, so if you are having trouble with your cuts, try slowing down. If the blade stalls or binds during the middle of a cut, stop immediately! This can be very dangerous if you continue to force the saw through material that it cannot cut at the speed you are using, you risk picking up pieces of wood that could fly right into your face with enough force to cause damage.
Perfectly circular circles aren’t just for fun, they’re very useful in many ways. Some examples include cutting holes for door knobs and drawer pulls on kitchen cabinets and dressers, creating round openings in fences, making round dots on paper crafts like cards and scrapbooks…the list goes on! No matter what you’re making, don’t be afraid to try using a circular saw instead of other tools. If you have the proper safety equipment and follow all rules for their use, they are safe to use almost anywhere!
Circular Saw Guide
The blade on a circular saw is actually designed in a way that makes it easy to cut perfect circles. Not only does it have teeth that point in alternating directions, but these teeth also have a slight incline from one side of the blade to the other. This allows for smooth cuts even if your angles aren’t exactly perfect just compensate with your pressure when pushing through each pass. When cutting a circle, always position yourself so that when you begin cutting, the direction in which the top edge of your circle is facing will be downhill. This allows the saw to follow the natural path of the blade, so it does not have to fight against gravity as you are cutting. Plus, with this method, your cut will always go smoothly even if you need to take more than one pass!
Another helpful hint for making smooth cuts is to slow down. The tendency when using a circular saw is that you want to hurry up and get through the material as fast as possible. That’s just human nature! But with increased speed comes an increased risk for mistakes like splintering or chipping of wood edges or kickback (when the part where you grip the saw starts pulling towards the blade), both of which can be dangerous. If you make sure that your saw is always under control, you can avoid these problems by making your cuts slowly and deliberately. Just remember to never force the saw through any material! The blade will only cut as fast as it’s able to, so if you’re having trouble getting through something, the issue isn’t speeding it’s probably that the blade is not capable of cutting your material.

A final way to make safe circular circles with a circular saw is to know where you are on your lines or marks at all times. When cutting along an arc or curve, this can be difficult because you cannot always see the entire line from one angle (especially when using a small circular saw like a jigsaw). Fortunately, many of these tools come equipped with lasers that project a line onto the material so you’ll always know where to cut. Alternatively, if your saw does not have a laser guide or you are using a larger circular saw for this project, you can always use a chalk line to mark straight lines for your blade to follow.
In addition, don’t forget that the wood itself may be in your way. Although it would be helpful if these tools could cut through anything and everything including dirt and concrete, table saws only work on certain types of materials cutting into bricks or natural stone can damage either tool or both! So, make sure the area around where you wish to make a circle is clear before starting out. And finally, don’t let these tips intimidate you! Remember no matter what cutting project you use a circular saw for, you will always have the best chance of success when you take your time and follow these basic tips!
Safety Precaution
Using a circular saw requires a lot of pressure to press through the material. If you’re not careful, this increased force could cause injury! Always follow the basic safety instructions listed on any tool you use so that you can avoid cutting yourself or anyone else nearby. Even though they are relatively safe, always wear protective eyewear and gloves when using a circular saw to minimize your risk! Read more here How to cut groove in wood with a table saw.
Features
- Circular saw blades have alternating teeth that face up or down on either side, each of which is slightly inclined
- Blades only cut as fast as they are able to so cutting slowly helps you avoid dangerous problems
- Position yourself so the downhill slope of the cut material will not cause any issues; this means if you start at the top, your blade should come down towards you.
- Also, remember to keep more pressure applied on the blade when it’s coming down!
- Laser guides help guide your cutting project; alternatively, use a chalk line to mark out straight lines for your blade to follow instead. You can also use these with larger circular saws like jigsaws.
Conclusion
The saw blade should be set to the depth of your material. Place your circle on a scrap piece, and use that as an indicator for where you will need to cut. When cutting out the center, keep in mind that it is best to leave at least 1/8” around all sides so there are no sharp edges – this ensures that the hole can fit over any dowel or rod used as support when displaying or hanging it from a wall. It’s also important to remember not to push down too hard on the saw handle while making cuts because doing so could cause a kickback which is very dangerous!
