How To Avoid Kickback On A Table Saw
Kickback is a common and dangerous problem that can occur while using a table saw. It happens when wood is forcefully thrown back towards the user, often at high speed. This can result in severe injury or even death. To prevent kickback and ensure your safety while using a table saw, it is important to follow some essential guidelines.
1. Use a Riving Knife: A riving knife is a safety device that can help prevent kickback. It is a thin metal blade positioned just behind the saw blade and runs parallel to it. The purpose of a riving knife is to prevent the wood from pinching the saw blade, which is a common cause of kickback. Always make sure the riving knife is properly installed and adjusted before starting any cuts.
2. Maintain Proper Blade Height: Setting the blade height correctly is crucial for preventing kickback. The blade should be set just above the top of the material being cut. If the blade is set too high, it increases the chance of kickback. On the other hand, if the blade is set too low, it can cause the material to bind and kick back. Take the time to adjust the blade height accurately for each specific cut.
3. Use a Blade Guard: A blade guard is another essential safety feature that can help prevent kickback. It is a transparent plastic cover that protects the user from contacting the spinning saw blade. Additionally, some blade guards also include anti-kickback pawls that grab the wood and prevent it from being thrown back. Always use a blade guard and make sure it is in good working condition.
4. Avoid Forceful Feeding: One of the main causes of kickback is forceful feeding of the material into the saw blade. Let the saw cut at its own pace and avoid pushing or pulling the wood forcefully. Use a gentle and steady feeding motion, allowing the blade to make the cut smoothly. If you encounter any resistance, stop the cut, assess the situation, and make the necessary adjustments before continuing.
5. Work with a Splitter: A splitter is similar to a riving knife but does not move up and down with the blade. It is a vertical metal strip that helps prevent the wood from binding and causing kickback. Some table saws come with integrated splitters, while others require a separate attachment. Regardless, using a splitter can greatly reduce the risk of kickback and increase your safety while using a table saw.
Remember, kickback can happen in an instant and can have serious consequences. Always prioritize safety and follow these guidelines to avoid kickback on a table saw. Stay alert, be aware of your surroundings, and never underestimate the importance of proper safety practices when working with power tools.
Understanding Kickback: Causes and Dangers
Kickback is a dangerous and potentially life-threatening occurrence that can happen when using a table saw. It refers to the sudden and violent upward movement of a piece of wood, propelled back towards the operator. This can cause severe injuries, including broken bones, lacerations, and even amputations.
Causes
There are several factors that can contribute to kickback on a table saw:
- Improper blade alignment: If the blade is not parallel to the rip fence, it can cause the wood to bind and kick back.
- Using a dull blade: A dull blade puts more strain on the motor and increases the likelihood of kickback.
- Incorrect feed rate: Feeding the wood too fast or unevenly can cause the blade to bind and kickback.
- Incorrect positioning of hands: Placing hands too close to the blade or over the path of the wood can result in serious injuries in case of kickback.
- Using a damaged or worn-out splitter: A splitter is a safety device that helps prevent kickback. If it is damaged or not properly aligned, kickback can occur.
Dangers
Kickback poses a significant risk to the operator and anyone in close proximity. The fast-moving piece of wood can cause serious injuries, such as:
- Lacerations: The wood can propel back at high speeds, causing deep cuts or even amputations.
- Fractures: The force of the kickback can result in broken bones, particularly in the hands, arms, and chest.
- Eye injuries: Flying debris from kickback can cause eye injuries or even blindness.
- Head and face injuries: The wood can strike the head or face, causing severe trauma and potential brain injuries.
It is crucial to be aware of the causes and dangers of kickback to prevent such accidents from happening. By practicing proper safety measures, maintaining the table saw and employing safe working techniques, you can greatly reduce the risk of kickback and ensure a safer woodworking experience.
Choosing the Right Blade and Fence
When it comes to avoiding kickback on a table saw, choosing the right blade and fence for your specific needs is crucial. These two factors play a significant role in ensuring the safety and accuracy of your cuts.
1. Blade Selection
First and foremost, you need to select the appropriate blade for the type of material you’ll be cutting. Different blades are designed for different purposes, such as ripping or cross-cutting, and they come in various styles and sizes.
For general woodworking tasks, a combination blade is a popular choice. These blades are typically designed to handle both ripping and cross-cutting tasks and offer a good balance between speed and smooth finish. However, if you frequently work with specific materials, such as hardwood or plywood, you may benefit from blades specifically designed for those materials.
It’s essential to ensure that the blade is sharp and in good condition. Dull blades can increase the risk of kickback and result in rough cuts. Regularly inspect your blade and replace it if there are any signs of wear or damage.
2. Fence Alignment
Another critical factor in preventing kickback is the alignment of the fence. The fence should be parallel to the blade and securely locked in place. This ensures that the workpiece will be guided along a straight path, reducing the chance of binding or kickback.
Check the alignment of your fence regularly using a square or a specialized alignment tool. Make any necessary adjustments to ensure that the fence is perfectly parallel to the blade. Additionally, ensure that the fence is secure and does not move during use.
Note: Some table saws come with a splitter or a riving knife attached to the blade guard. These are designed to prevent kickback by keeping the kerf open behind the blade. Make sure these safety features are properly installed and adjusted for maximum effectiveness.
By selecting the right blade and aligning the fence correctly, you can significantly reduce the risk of kickback on your table saw. Remember to always prioritize safety and take the time to make necessary adjustments before starting any cutting operation.
Proper Set-Up and Adjustment
Proper set-up and adjustment of your table saw is crucial for avoiding kickback and ensuring accurate cuts. Here are some key steps to follow:
1. Blade Alignment
Make sure that the saw blade is aligned parallel to the miter slots and fence. Use a combination square or a specialized blade alignment tool to adjust the blade if necessary. A misaligned blade can cause binding and kickback.
2. Fence Positioning
The fence should be properly positioned parallel to the blade. Use a measuring tape or a fence alignment tool to ensure that it is perfectly parallel. A misaligned fence can cause the workpiece to bind against the blade, leading to kickback.
3. Blade Height
The height of the blade should be set according to the type and thickness of the material being cut. The blade should be raised above the material by about 1/8 inch to minimize contact and reduce the chance of kickback.

2. Fence and Miter Gauge
- Make sure that the fence and miter gauge are properly aligned and securely locked in place before making any cuts.
- Ensure that the fence is parallel to the blade and that the miter gauge is at a 90-degree angle to the blade. This will help prevent the workpiece from binding and reduce the chances of kickback.
3. Push Stick or Push Block
- Always use a push stick or push block when making narrow or small cuts, as this will keep your hands a safe distance from the blade and reduce the risk of kickback.
- Make sure to maintain a firm grip on the push stick or push block and apply even pressure when feeding the material through the saw.
4. Positioning
- Position yourself to the side of the blade, not directly behind it. This will help protect you from flying debris in case of kickback.
- Stand with your feet shoulder-width apart and maintain a stable stance to ensure better control and balance while cutting.
5. Clean Workspace
- Ensure that your workspace is clean and free from clutter. This will help prevent any objects from interfering with the cutting process and causing kickback.
- Remove any loose materials or scraps from the table surface before starting your cuts.
