The Delta DPEC006136 Table Saw Riving Knife is a replacement safety component designed to support accurate cutting and improve operational safety on compatible table saws. It works by positioning directly behind the saw blade to keep the cut material separated, helping prevent the workpiece from pinching the blade or causing kickback during operation. This is used to maintain smooth cutting performance, support better material control, and enhance user safety while making rip cuts. Ideal for repair and routine maintenance, the riving knife is used to restore the original functionality of compatible table saws, contributing to reliable and consistent woodworking performance.
