A table saw is a powerful tool used by woodworkers to make straight cuts in various materials, such as wood, plastic, and metal. One important component of a table saw is the splitter. The splitter is a thin and vertical piece of metal or plastic that is positioned behind the saw blade.
The main function of a splitter is to prevent the wood from closing in and binding on the saw blade. When a board is cut on a table saw, it has a tendency to close in on the back of the saw blade as it is being cut. This can result in a dangerous kickback, where the piece of wood is thrown back towards the operator with great force.
The splitter prevents kickback from occurring by keeping the kerf (the width of the cut) open behind the blade. It acts as a barrier that helps to keep the wood on the correct sides of the blade, preventing it from binding. This not only improves safety but also ensures cleaner and more accurate cuts.
Some splitters are fixed in position, while others can be adjusted to match the width of the kerf. There are also variations of splitters that include additional features, such as anti-kickback pawls or riving knives. These added safety features further reduce the risk of kickback and improve the overall performance of the table saw.
In summary, a splitter on a table saw is a vital safety device that helps to prevent kickback and ensures cleaner and more accurate cuts. It is an essential component for any woodworker, and understanding its importance and function is crucial for working safely with a table saw.

What is a Splitter?
A splitter is an essential component of a table saw that helps improve safety and precision when cutting wood or other materials. It is typically a vertical piece of metal or plastic with sharp teeth that sits directly behind the saw blade.
The main purpose of a splitter is to prevent the wood from squeezing together and binding the blade during the cutting process, which can cause dangerous kickback. Kickback occurs when the wood is forcefully thrown back towards the operator, posing a serious risk of injury. The splitter helps keep the wood aligned and prevents it from twisting or closing on the blade.
In addition to its safety function, a splitter also helps in achieving accurate and clean cuts. By keeping the kerf, or the width of the cut, open, it ensures that the material being cut is evenly separated and avoids any pinching or burning. This results in a smoother finish and reduces the need for additional sanding or trimming.
There are different types of splitters available, such as riving knife splitters and anti-kickback pawls. A riving knife is a splitter that is attached directly to the blade mechanism and moves up and down with the blade.
