Circular saws are popular power tools used in woodcutting. They are versatile, efficient, and easy to use. However, they can also be dangerous if not used properly. One of the most common accidents that can happen when using a circular saw is kickback. Kickback is when the saw blade suddenly jerks back towards the user, often causing injury or damage to the workpiece. In this article, we will explore why circular saws kickback and how to prevent it.
What is Kickback?
Kickback occurs when the saw blade catches on the wood, pinches it, and then suddenly jerks back towards the user. The force of the kickback can be strong enough to cause serious injury, such as cuts, bruises, or broken bones. Kickback can also cause damage to the workpiece or the saw itself.
Why Do Circular Saws Kickback?
There are several reasons why circular saws kickback. Understanding these reasons can help you prevent kickback and use the saw safely.
1. Dull or Damaged Blade
A dull or damaged blade is more likely to catch on the wood and cause kickback. A blade that is not sharp enough can also cause the user to apply too much force, which can lead to kickback. Check your blade regularly for dullness, chips, or cracks. Replace the blade if necessary.
2. Improper Blade Depth
If the blade depth is not set correctly, it can cause kickback. The blade should be set so that it only cuts through the wood, not into the table or workbench. If the blade is too deep, it can catch on the wood and cause kickback.
3. Wrong Blade Type
Using the wrong blade for the job can also cause kickback. Blades that are too wide or too narrow for the material being cut can catch on the wood and cause kickback. Make sure you use the correct blade for the job.
4. Poor Technique
Poor technique is another common cause of kickback. For example, if you force the saw through the wood too quickly or twist the saw while cutting, it can cause kickback. Always use proper technique when using a circular saw.
How to Prevent Kickback?
Now that you know why circular saws kickback, here are some tips on how to prevent it.
1. Use a Sharp Blade
Make sure your blade is sharp and in good condition. Dull or damaged blades are more likely to cause kickback.
2. Set Blade Depth Correctly
Set the blade depth correctly so that it only cuts through the wood, not into the table or workbench.
3. Use the Correct Blade
Use the correct blade for the job. Blades that are too wide or too narrow for the material being cut can cause kickback.
4. Use Proper Technique
Always use proper technique when using a circular saw. Do not force the saw through the wood too quickly or twist the saw while cutting.
5. Use a Riving Knife
A riving knife is a safety feature that helps prevent kickback. It is a small, vertical blade that sits behind the saw blade and prevents the workpiece from pinching the blade. If your saw does not have a riving knife, consider installing one.
Conclusion
Kickback is a common accident that can happen when using a circular saw. Understanding why circular saws kickback and how to prevent it can help you use the saw safely. Always use proper technique, use a sharp blade, set the blade depth correctly, use the correct blade for the job, and consider using a riving knife. Stay safe and happy sawing!
