A rigid planer is a woodworking machine that is used to flatten and smooth the surface of wood. It consists of a rotating cutter head with multiple blades that remove thin layers of wood as the workpiece passes through. Rigid planers are typically used for larger pieces of wood, such as planks and boards, and can produce a very smooth and even finish.
Rigid planers are an essential tool for any woodworker, as they can greatly improve the quality and appearance of finished projects. They are also relatively easy to use, making them a good choice for both beginners and experienced woodworkers alike.
