Why Blade on Chain Saw Snap in Half?

There are many reasons for the blade to snap on a chain saw. Here we will discuss all reasons why chainsaw blades snap in half.

Why Blade on Chain Saw Snap in Half?


One of the most common causes is too much heat. This can cause the blade to warp, which can eventually lead to breakage. Proper maintenance of your chain saw can also prevent the problem. It’s a good idea to keep the chain sharp and lubricated.

Cutting angle

Another factor that could contribute to chain saw blade snapping is its cutting angle. A saw’s angle will affect its efficiency. This is because saw file gullets are pointed. This angle makes the saw more difficult to cut. So, you may have to adjust the angle of your saw.

Lack of knowledge

Another possible cause is the lack of training and knowledge. Beginners are likely to mishandle their chainsaws, which can lead to chain breakage. Whether you are using a gas-powered chainsaw or an electric chainsaw, you should be familiar with all the common causes of chain breakage.


One of the most common reasons for snapping during use is a lack of proper maintenance. Using the correct amount of coolant reduces the possibility of overheating the saw. The wrong type of coolant can produce foam or not provide adequate cooling during the cut. The feed pressure is also another factor. This controls how fast the blade moves from one cut to the next.

How to avoid snapping?

There are a few things you can do to prevent a Chain Saw from snapping in half. First, release the brake on the chain before starting the saw. Also, fully engage the throttle while using an electric chain saw. This way, the blade and chain will draw the wood together. For corded electric saws, you must keep the throttle engaged throughout the cut. The next step is to remove the saw after cutting.

Ensure that the chain is properly tensioned. Ideally, the chain should be about half an inch loose on the guide bar, or snug enough to prevent the drive links from coming out of the nose of the bar. Too tight a chain can break, so it’s vital to check your tension before using your chainsaw.

Another important step is to sharpen the chainsaw. If the saw is cutting unevenly or pulling to one side, you may have a chainsaw problem. Make sure the top plates on each tooth on the chain are the same length. If they are not, file them down to match the shorter ones. Also, make sure the angle of each tooth is similar.

Conclusion: Why Blade on Chain Saw Snap in Half

When you use a chain saw, the most important part is the blade. The blade can snap for a variety of reasons. Understanding what causes it can help you avoid problems before they happen. If you know what to look for, you can fix a broken blade quickly and prevent it from happening again.
