When working with saws, one of the biggest challenges that you may face is keeping the saw kerf from closing. A saw kerf is the space that is created when you cut through a piece of material with a saw. It is often wider than the saw blade, and if it closes up, it can cause problems with your cut. So, what do you use to keep the saw kerf from closing? Let’s take a look at some options.
Kerf Keepers
A kerf keeper is a small device that is designed to keep the kerf open as you cut. It is typically made of a thin piece of plastic or metal, and it fits into the saw kerf behind the blade. The kerf keeper keeps the kerf open by pushing against the sides of the cut as you saw. This prevents the material from closing in on the blade and binding it, which can cause the saw to stop or kick back.
Wedge Blocks
Another option for keeping the saw kerf from closing is to use wedge blocks. These are small blocks of wood or plastic that are placed into the kerf behind the blade. The wedge blocks keep the kerf open by applying pressure to the sides of the cut. They are especially useful when cutting thicker materials that have a tendency to close up around the blade.
File Cards
File cards are small brushes that are used to clean saw blades. However, they can also be used to keep the saw kerf from closing. To use a file card, simply run it through the kerf behind the blade as you saw. The bristles of the brush will help to keep the kerf open by pushing against the sides of the cut. This is a simple and inexpensive solution that can be especially helpful when working with thinner materials.
Conclusion
There are several different options for keeping the saw kerf from closing. Kerf keepers, wedge blocks, and file cards are all effective solutions that can help to prevent binding, kickback, and other issues when sawing. When choosing a method, consider the type of material you are cutting, the thickness of the material, and the type of saw blade you are using. With the right tools and techniques, you can achieve clean, precise cuts every time.
