What is a riving knife and why is it important?
A riving knife is a safety feature on table saws designed to prevent kickback during cutting operations. It is a vertical blade that aligns with the saw blade and is positioned behind it. When making a cut, the riving knife allows the material being cut to separate without binding around the blade, which drastically reduces the chances of the material kicking back towards the operator.
In addition to enhancing safety, the riving knife also improves the quality of the cut by helping to keep the material straight and aligned. It maintains a consistent width between the blade and the back of the workpiece, promoting smoother cuts. Understanding its importance is crucial for using your Dewalt table saw properly and safely.
How do I know when to remove the riving knife?
You might need to remove the riving knife when performing certain specialized cuts that require unleashing the full potential of the saw, such as when using a dado blade setup or making bevel cuts where extra clearance is required. However, it is essential to consult your table saw’s instruction manual for specific guidance on these scenarios.
Before removing the riving knife, always ensure that your operations align with safety guidelines. Whenever feasible, it is best to keep the riving knife in place during normal straight cuts to take advantage of its protective properties, as it plays an essential role in preventing kickback.
What tools do I need to safely remove the riving knife?
To safely remove the riving knife from your Dewalt table saw, you generally just need a wrench or screwdriver, depending on the model of your saw. Most Dewalt table saws have a simple mechanism that allows for easy removal, often with just a thumb screw or knob that can be loosened by hand. Always refer to your specific model’s owner manual for precise instructions and necessary tools.
Additionally, it’s essential to have a clean and clear workspace when performing this task. Make sure the saw is unplugged from the power source to eliminate any risk of accidental start-up while removing the riving knife. This creates a safer environment where you can work with focus and care.
What are the steps to safely remove the riving knife?

Next, lower the blade to its lowest position, which will give you better access to the riving knife without interference. Check the saw for any mechanisms or screws that hold the riving knife in place.
Once you have identified the securing mechanism, loosen or remove it with the appropriate tool, such as a wrench or screwdriver. Carefully lift the riving knife away from its mount and store it safely in a designated location. Remember to review the procedure in your saw’s manual to ensure that you are not missing any important steps or safety recommendations.
Can I operate the table saw without a riving knife?
While you can technically operate a table saw without a riving knife, it is highly inadvisable due to the increased risk of kickback—which can lead to serious injuries. The riving knife is designed to act as a safeguard, and removing it compromises the saw’s functionality and safety features. If you must work without it for specific cuts, be extra cautious and employ additional safety measures.
If you decide to operate the saw without a riving knife, it’s crucial to have a full understanding of the workpiece you are handling and to maintain a hand’s distance away from the blade at all times.

Use a brush or compressed air to clear any obstructions you can see, ensuring nothing is blocking the knife’s disengagement.
If the riving knife remains stuck despite your efforts, refer back to your user manual or contact Dewalt’s customer service for troubleshooting advice. Avoid using excessive force, as this can damage both the knife and the saw. Remaining patient and seeking professional help can ensure your equipment stays in optimum condition while maintaining your safety.
