what does a planer do

A planer is a tool used in woodworking to smooth, flatten, and shape wooden surfaces. It is used to level the flat surfaces of a board to a consistent thickness. A planer typically consists of a feeding mechanism from which wood is fed through the cutting blades that are adjusted depending on the desired depth or finish of the surface being planed. Common features found on most planers include blade stops for safety, adjustable feed rollers, dust collection ports, and cutter head locks. Planers should only be used to mill a board to a uniform thickness from rough-cut lumber, and they can also be used to reduce the thickness of already surfaced boards for a specific woodworking project. Planers are also a useful woodworking tool when it comes to creating a flat surface from a glue-up. Using a planer offers a number of advantages, making it an invaluable tool for any home craftsman or woodworker.
