A rip fence is a tool used in woodworking, specifically on a table saw, to guide the material being cut. It helps ensure straight, accurate cuts by providing a stable edge against which the wood can be positioned. The rip fence can be adjusted to accommodate different widths of cuts, making it versatile for various projects. Typically made of metal or sturdy plastic, the rip fence is mounted parallel to the saw blade. Proper alignment of the rip fence is crucial for safety and precision, as misalignment can lead to uneven cuts or accidents. Using a rip fence enhances the efficiency of cutting long pieces of wood, such as boards or sheets.
