What is a Riving Knife on a Table Saw?
A riving knife on a table saw is a safety device that is attached to the arbor of a table saw. It sits behind the blade and moves up and down with it, ensuring that there is always a small gap between the blade and the riving knife. The primary function of a riving knife is to prevent kickback — a common occurrence in table saw accidents where the workpiece is propelled backwards towards the operator at a high speed.
10 Uses of a Riving Knife on a Table Saw
1 . Increased Safety
The primary function of a riving knife is to reduce the risk of kickback while using a table saw. Kickback occurs when a piece of wood being cut gets caught on the blade and is thrown back towards the user at high speeds. This can be extremely dangerous and even fatal if proper safety measures are not in place. A riving knife helps prevent this by keeping the wood from getting caught on the blade and causing kickback.
2. Clearer Cut Lines
In addition to increasing safety, a riving knife also helps to create cleaner cut lines. It keeps the workpiece in place and prevents it from twisting or shifting while being cut. This results in more accurate cuts and less wasted material.
3. Reduces Splintering
Splintering can occur when a piece of wood is not properly supported while being cut, causing it to tear and create rough or jagged edges. A riving knife helps prevent this by keeping the workpiece in place and providing support throughout the cutting process.
4. Minimizes Tear-out
Similar to splintering, tear-out is when the wood fibers are pulled away from the surface of the workpiece as it is being cut. This can result in rough and uneven edges. A riving knife helps minimize tear-out by keeping the wood stable and preventing it from moving or shifting while being cut.
5. Can Be Used with Different Types of Blades
A riving knife can be used with a variety of blades, including standard blades, dado blades, and thin-kerf blades. This versatility allows for greater flexibility in the types of cuts that can be made on a table saw.
6. Easy to Install and Adjust
Most modern table saws come equipped with a riving knife and it is relatively easy to install and adjust as needed. This allows for quick and easy changes when switching between different types of cuts or blades.
7. Can Be Used with Different Angles
Riving knives can also be used at different angles, allowing for more specialized cuts such as bevels and miters. This expands the capabilities of a table saw and makes it a more versatile tool in any woodworking shop.
8. Can Be Interchanged with Splitters
In some cases, a riving knife can be interchanged with a splitter, which is a similar device used for the same purpose. This allows for even more customization and adaptability when using a table saw.
9. Helps Prevent Wood from Binding
Wood binding occurs when the workpiece gets stuck on the blade, often due to heat or pressure. This can be dangerous and can also result in damaged blades. A riving knife helps prevent wood binding by keeping the workpiece stable and reducing the amount of friction between it and the blade.
10. Required for Safety Compliance
In many countries, including the United States, having a waving knife on a table saw is a legal requirement for safety compliance. This ensures that all woodworkers are using the necessary safety precautions when operating a table saw, making it an essential component in any woodworking shop.
Conclusion
Now you know what is a riving knife on a table saw? This essential safety device is a crucial component that should never be overlooked when it comes to using a table saw. It plays a vital role in preventing kickback accidents, which can cause serious injuries.
