Why Does My Table Saw Kickback
If you use a table saw regularly, you may have experienced the frustrating and potentially dangerous phenomenon known as kickback. Kickback occurs when a piece of wood being cut gets caught by the saw blade and is violently thrown back towards the operator. This can happen for several reasons, but one of the most common is improper technique.
When using a table saw, it is important to always use the appropriate feeding technique. This means keeping the wood firmly against the fence and using a push stick or push block to guide it through the blade. Failure to do so can result in the wood binding against the blade, causing kickback. It is also important to use a splitter or riving knife, which helps to prevent the wood from pinching the blade and causing kickback.
Another common cause of kickback is using a dull or improperly aligned blade. A dull blade can cause the wood to bind against the blade, increasing the risk of kickback. Similarly, if the blade is not properly aligned with the fence, it can cause the wood to shift during cutting and result in kickback. Regularly checking and maintaining your table saw blade can help prevent kickback.
Finally, kickback can also occur when trying to cut wood that is warped or has internal tension. These types of wood can shift during cutting, leading to kickback. It is important to inspect your wood before cutting and avoid using pieces that are warped or have visible defects. Taking the time to properly prepare your wood can help prevent kickback and ensure a safer cutting experience.
In conclusion, kickback is a common problem when using a table saw, but it can be prevented by using proper technique, maintaining your equipment, and thoroughly inspecting your wood before cutting. By following these guidelines, you can reduce the risk of kickback and ensure a safer working environment.

What is Table Saw Kickback?
Table saw kickback is a dangerous and potentially harmful occurrence that can happen while using a table saw. It refers to the sudden and forceful backward movement of a workpiece towards the operator. This happens when the workpiece gets caught or pinched between the blade and the fence, causing it to be propelled back with great force.
Kickback can occur for various reasons, including a misaligned or improperly installed blade, a dull blade, improper feeding technique, or when cutting a warped or twisted board. It can also occur if the workpiece is not properly supported or if the operator does not use a push stick or a feather board to keep the workpiece stable.
Kickback is a dangerous situation because it can cause serious injury or even death. The force of the kickback can launch the workpiece at a high speed, potentially hitting the operator or anyone else nearby. It can also cause the operator to lose control of the saw, leading to further accidents and injuries.
To prevent kickback, it is important to follow safety guidelines and precautions while using a table saw. This includes ensuring that the blade is properly aligned and installed, using a sharp blade, using a push stick or feather board to keep the workpiece stable, and properly supporting the workpiece during cutting. It is also important to use proper feeding techniques, such as feeding the workpiece smoothly and evenly through the blade.
By being aware of the risks of kickback and taking proper precautions, users can significantly reduce the chances of this dangerous occurrence happening while using a table saw.
Causes of Table Saw Kickback
Table saw kickback occurs when the workpiece binds against the blade and is thrown back towards the user at a high speed. This can be extremely dangerous and can cause serious injuries. Understanding the causes of table saw kickback is crucial for preventing accidents and ensuring a safe working environment.
1. Incorrect Saw Blade Alignment: One of the main causes of kickback is the misalignment of the saw blade. If the blade is not aligned parallel to the fence or miter gauge, it can lead to pinching and binding of the workpiece, resulting in kickback.
2. Blade Dullness: A dull blade can increase the chances of kickback as it requires more force to cut through the wood. This can cause the blade to get stuck in the workpiece, leading to kickback. Regularly sharpening and replacing the blade is essential to prevent this situation.
3. Improper Fence Usage: A fence is used to guide the workpiece during the cutting process. If the fence is not properly adjusted and parallel to the blade, it can cause the workpiece to bind against the blade and kick back. Always ensure that the fence is properly aligned before making any cuts.
4. Incorrect Riving Knife or Splitter Installation: A riving knife or splitter is a safety feature designed to prevent kickback by keeping the workpiece from closing in on the back of the blade. If these components are not properly installed or adjusted, the risk of kickback significantly increases.
5. Pushing the Workpiece Improperly: Applying uneven pressure or pushing the workpiece too quickly through the blade can cause it to bind and kick back. It is important to use a steady and controlled pushing motion to avoid kickback incidents.
6. Inadequate Material Support: Insufficient support for the workpiece can result in kickback. Lack of proper support can cause the workpiece to tip or fall off the table during cutting. Use additional support tools, such as roller stands or outfeed tables, to prevent kickback.
7. Wrong Blade Height: Setting the blade too high can increase the chances of kickback. When the blade extends above the workpiece, it creates a larger gap for the wood to bind, increasing the risk of kickback. Always adjust the blade height to be slightly higher than the material being cut.
By understanding and addressing these causes of table saw kickback, you can significantly reduce the risk of accidents and ensure a safer working environment. Always prioritize safety and take the necessary precautions when operating a table saw.
