Circular saws are a great tool for cutting through a variety of materials quickly and easily. One feature of circular saws that often goes unnoticed is the two notches on the blade. These notches serve an important purpose and can help you get the most out of your saw.
The first notch is the arbor notch. This is a small indentation on the blade that is designed to fit onto the arbor of your circular saw. The arbor is the shaft that holds the blade in place and allows it to spin. The notch ensures that the blade is centered on the arbor and prevents it from wobbling as it spins. This is important for both safety and accuracy.
When installing a new blade on your saw, it’s important to make sure that the arbor notch lines up with the arbor. If it doesn’t fit snugly, the blade may wobble while in use, which can lead to an uneven cut or even a dangerous situation. Always double-check that the blade is seated properly before beginning your cut.
The second notch is the anti-kickback notch. This is a larger, more noticeable notch that is typically located on the back of the blade. Its purpose is to prevent the saw from kicking back during a cut. Kickback occurs when the blade catches on the material being cut and is suddenly thrown back towards the user. This can be extremely dangerous and can cause serious injury.
The anti-kickback notch helps prevent kickback by allowing a small amount of material to escape from the kerf (the cut made by the blade) as the cut is being made. This relieves some of the pressure on the blade and reduces the likelihood of it catching on the material.
It’s important to note that the anti-kickback notch is not a fail-safe mechanism. It’s still possible for kickback to occur, especially if the saw is not being used properly. Always make sure to follow the manufacturer’s instructions for your saw and use it safely and responsibly.
In addition to the two notches, circular saw blades may also have other features that can improve their performance. Some blades have laser guides that can help you make straighter cuts, while others have specialized teeth designed for cutting specific materials.
When selecting a circular saw blade, it’s important to choose one that is appropriate for the material you will be cutting. Using the wrong blade can lead to poor performance, uneven cuts, and even damage to your saw.
In conclusion, the two notches on a circular saw blade serve important purposes that can help you get the most out of your saw. The arbor notch ensures that the blade is properly centered on the arbor, while the anti-kickback notch helps prevent dangerous kickback. When using a circular saw, always make sure to use it safely and responsibly, and choose the right blade for the job.

Frequently Asked Questions about What Are The Two Notches On A Circular Saw?
What are the two notches on a circular saw for?
The two notches on a circular saw are used to guide the saw when making angled cuts. These notches, also known as bevel stops, help to ensure that the saw blade stays at the correct angle when making bevel cuts.
How do I use the notches on a circular saw?
To use the notches on a circular saw, first set the angle of the bevel using the saw’s bevel adjustment knob. Then, align the appropriate notch with the saw blade and secure the bevel stop in place. This will ensure that the saw blade stays at the correct angle when making your cut.
Can I make angled cuts without using the notches on a circular saw?
Yes, you can make angled cuts without using the notches on a circular saw, but it may be more difficult to get an accurate cut. Using the notches on the saw helps to ensure that the blade stays at the correct angle throughout the cut, resulting in a more precise and accurate cut.
