Table saw kickback is a dangerous situation that can occur when using a table saw. It happens when the wood being cut gets caught on the back of the saw blade and is forcefully thrown back towards the operator. This can result in serious injury or even death if proper precautions are not taken.
There are several factors that can contribute to table saw kickback. One of the main causes is using the wrong blade for the type of material being cut. Using a blade that is not appropriate for the type of wood or other material being cut can cause the saw to bind and kickback. It is important to use the correct blade for the job to reduce the risk of kickback.
Another factor that can contribute to table saw kickback is improper feeding of the material. When feeding material into the saw, it is important to use a steady and consistent pressure. Pushing the material too fast or too slow can cause the saw to bind and kickback. It is important to maintain control of the material at all times and avoid any sudden movements that could lead to kickback.
Table saw kickback can also occur when the saw blade is not properly aligned or when the fence is not secure. If the blade is not aligned correctly, it can cause the material to bind and kickback. Additionally, if the fence is not securely locked in place, it can result in the material being cut to shift and cause kickback. It is important to regularly check that the blade is aligned and that the fence is secure to reduce the risk of kickback.
In conclusion, table saw kickback is a dangerous situation that can be avoided by taking proper precautions. Using the correct blade, feeding material correctly, and ensuring the blade and fence are properly aligned are all important factors in reducing the risk of kickback. By following these guidelines, you can work safely with a table saw and minimize the risk of injury.

What Causes Table Saw Kickback?
Table saw kickback is a dangerous and potentially injury-causing occurrence that can happen while using a table saw. It refers to the sudden and powerful movement of a workpiece that is being cut, which can be propelled directly back toward the operator. This can result in serious injuries and damage to the saw and workpiece.
There are several factors that can cause table saw kickback:
1. Incorrect fence placement: If the fence is not aligned properly, it can trap the workpiece against the blade. This can cause the workpiece to bind and possibly kickback.
2. Dull or improper blade: A blade that is not sharp or is not appropriate for the type of cut being performed can increase the risk of kickback. Dull blades are more likely to bind and can cause the workpiece to be thrown back at high speed.
3. Splitter or riving knife absence: These safety devices help prevent kickback by keeping the kerf open and preventing the workpiece from closing in on the blade. If a table saw does not have a splitter or riving knife, the risk of kickback is significantly increased.
4. Incorrect push stick or improper hand placement: Using the wrong type of push stick or not following proper hand placement techniques can contribute to kickback. It is important to use a push stick with sufficient length and keep hands at a safe distance from the blade.
5. Improper cutting technique: Cutting techniques that are too fast or uneven can increase the risk of kickback. It is important to maintain a steady and controlled feed rate, ensuring that the workpiece is properly supported and guided throughout the cut.
Overall, table saw kickback can occur due to a combination of factors. It is essential to be aware of these potential causes and take necessary precautions to reduce the risk of kickback. This includes using appropriate safety devices, following correct cutting techniques, and maintaining the saw and its accessories properly.
Preventing Table Saw Kickback
Table saw kickback is a dangerous and often frightening occurrence that can cause serious injury. It happens when the wood being cut gets caught by the blade and is forcefully thrown back towards the operator. Fortunately, there are several steps that can be taken to help prevent table saw kickback:
1. Use a Riving Knife
A riving knife is a safety device that helps prevent kickback by keeping the wood from pinching the blade. It is mounted just behind the blade and follows the blade’s height and angle adjustments. The riving knife should be properly secured and aligned with the blade to effectively prevent kickback.
2. Use a Splitter
A splitter is another safety device that can be used to prevent kickback. Similar to a riving knife, it helps to keep the wood from pinching the blade. However, unlike a riving knife, a splitter does not move with the blade’s height and angle adjustments. It is a fixed piece that is set in line with the blade and helps to prevent kickback.
Both a riving knife and a splitter serve the same purpose, but they have different designs and functionalities. Some table saws come with either a riving knife or a splitter, while others may have both as separate attachments.
3. Use a Featherboard
A featherboard is a device that applies pressure to the wood being cut, pushing it against the table’s fence and preventing it from lifting or shifting during the cutting process. This helps to reduce the likelihood of kickback. Featherboards can be clamped or attached to the table saw’s fence to ensure a secure hold on the wood.
4. Maintain Proper Blade Height and Angle
Using the correct blade height and angle is crucial for preventing kickback. When the blade is set too high or at an incorrect angle, it can increase the chances of the wood being caught and thrown back. Always follow the manufacturer’s instructions for setting up the blade correctly.
5. Avoid Using Dull Blades
Dull blades can increase the likelihood of kickback since they are more likely to bind or get stuck in the wood. Regularly inspect and replace blades to ensure they are sharp and in good working condition.
| Warning Signs of Kickback | Corrective Actions |
|---|---|
| The wood starts to lift during the cut | Apply downward pressure to keep the wood against the table and fence, or use a featherboard to provide additional support. |
| The wood starts to bind or gets stuck in the blade | Turn off the saw and wait for the blade to stop completely before gently removing the wood. Check for any abnormalities with the blade or wood that may have caused the binding. |
| The wood is forcefully thrown back at the operator | Step away from the table saw immediately to avoid injury. Examine the cause of the kickback and make necessary adjustments before continuing. |
Remember, table saw kickback can happen suddenly and unexpectedly. Always prioritize safety and follow proper operating procedures to minimize the risk of kickback and ensure a safe woodworking environment.
