Planer
A planer is a woodworking power tool that shaves thin layers from the surface of lumber, leaving boards flat, smooth and consistent in thickness. Whether you are milling rough-sawn boards for a furniture build, fitting a door, or trimming trailer and truck-bed lumber, a planer delivers a level of accuracy that sanding and hand tools struggle to match.
What Does a Planer Do?
Planers remove material in controlled passes using rotating cutterheads fitted with sharp knives. The result is a uniform surface and, with the right machine, a precise final thickness. Smooth, dimensionally accurate stock matters for tight joinery, clean finishes and projects where parts must fit together exactly, from workshop cabinets to custom vehicle interiors, camper builds and boat trim.
Main Types of Planers
- Thickness planers (benchtop): Feed boards through the machine to reduce them to a uniform thickness. They are ideal for milling rough lumber or reclaimed wood and for matching board thicknesses across a project.
- Handheld planers: Portable and easy to control, these are suited to trimming doors, smoothing edges, chamfering and making quick on-site adjustments.
- Stationary and jointer-planer machines: Larger shop tools that handle heavy production work and wide stock.
What to Consider When Shopping
- Cutting capacity: Check maximum board width and depth of cut per pass so the tool matches the lumber you actually work with.
- Motor power: Hardwoods and wide boards demand more power to avoid bogging down and leaving ridges.
- Knife type and changeability: Reversible or easily replaceable blades keep the tool cutting cleanly and reduce downtime.
- Dust collection: Planers produce a lot of chips. Good dust ports keep the shop cleaner and improve visibility on the cut.
- Portability: Job-site users will want a lighter, compact tool, while shop owners may favor a heavier machine for stability and reduced vibration.
- Power source: Corded tools offer consistent power, while cordless options add convenience away from an outlet.

Getting the Best Results
For clean cuts, feed boards with the grain, take light passes rather than removing too much material at once, and keep knives sharp. Inspect lumber for nails, screws or grit before planing, especially with reclaimed wood, since hidden hardware can quickly damage blades. With proper setup and maintenance, a quality planer will serve for years and make every woodworking, repair or restoration project more precise.
