A wood planer is a tool used in woodworking to create flat, smooth surfaces on wooden boards. It works by shaving off thin layers of wood, allowing you to adjust the thickness and remove imperfections. This tool is essential for preparing lumber for projects, ensuring that pieces fit together well and look professional. There are two main types of wood planers: hand planers and electric planers. Hand planers are manually operated and require physical effort, while electric planers are powered by electricity, making the job quicker and easier. Both types help woodworkers achieve the desired finish for their projects.
