Using a Riving Knife or Splitter
One effective way to prevent kickback while using a circular saw is to use a riving knife or splitter. These safety devices are installed behind the saw blade and help to keep the workpiece from binding or pinching against the blade, reducing the likelihood of kickback.
A riving knife is a vertical projection that aligns with the saw blade and sits directly behind it. It moves up and down with the blade, ensuring that it is always in the correct position to prevent kickback. Some circular saws come with a built-in riving knife, while others may require you to purchase and install one separately.
A splitter, on the other hand, is a fixed, stationary projection that is slightly wider than the saw blade. It is positioned behind the blade and does not move up and down. Splitters are commonly found on table saws and can also be used on circular saws by attaching them to the saw’s guard. They help to prevent the workpiece from closing in on the back of the blade and causing kickback.
When using a circular saw with a riving knife or splitter, it’s important to make sure that the device is properly installed and adjusted. It should be positioned so that it sits slightly lower than the top of the teeth on the saw blade. This allows the device to effectively prevent kickback without interfering with the cutting action of the blade.
Always remember to keep the riving knife or splitter clean and free of any debris that may accumulate during use. This will ensure that it functions properly and reduces the risk of kickback. Additionally, make sure to follow the manufacturer’s instructions for installing and adjusting the riving knife or splitter to ensure optimal safety.
