A rebate router cutter, also known as a rabbet cutter or rebate bit, is a cutting tool used in woodworking to create a groove or recess on the edge of a workpiece. The cutter has a flat cutting surface and a guide bearing that runs along the edge of the workpiece, creating a consistent and even cut.
Rebate router cutters come in a variety of sizes and shapes, with different depths and widths of cut. They can be used to create a variety of joints, such as rabbet joints and dado joints, as well as decorative edge profiles.
When using a rebate router cutter, it's important to take proper safety precautions, such as wearing eye and ear protection and using a secure surface to hold the workpiece. It's also important to use the proper technique to ensure that the cut is consistent and even along the entire length of the workpiece. Adjusting the depth of cut and taking multiple passes with the router can help achieve a clean and precise cut. A featherboard can also help keep the workpiece securely in place while cutting.
