We have not used these products ourselves, so this guide does not claim any personal results. Instead it shows how to choose a thickness planer by looking at the features that shape shop use: cutterhead design, width capacity, dust handling and how easily you can set the depth. Use the table below to compare options, then check the maker details against your own projects and space before you decide.
A thickness planer shaves a board to a uniform thickness so both faces run parallel. Woodworkers use one to turn rough lumber into usable stock, to match boards for a tabletop, or to reclaim old timber. Portable benchtop units suit small shops, while larger stationary machines handle wider boards and heavier daily work. Think about the widest board you plan to cut, how often you plane, and where the machine will live. Power requirements, noise and weight matter too, as does the supply of replacement knives. Read the manual before you buy, since it describes the maker’s recommended passes and settings. Read each product page closely for what is included, such as a dust hood or extra blades.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Cutterhead | Straight knives and spiral heads leave different finishes and have different upkeep. | Check the type, blade count and how replacements are sold. |
| Width capacity | Boards wider than the bed cannot be planed whole. | Compare the maximum width and thickness with your usual lumber. |
| Depth adjustment | Easy, accurate settings save time and wasted wood. | Look for a clear scale, a smooth crank and a depth stop. |
| Dust collection | Planers produce a large volume of chips. | Check the port diameter and whether a hose or hood is included. |
| Bed and rollers | Support length keeps boards flat as they feed. | Consider extension tables and how the rollers grip the board. |
| Weight and power | Heavy units resist movement but are harder to carry. | Check the listed weight and the electrical needs for your shop. |
Setup and Care Tips
- Set the machine on a solid bench or stand and fasten it as the manual describes.
- Connect a dust hose or collector before the first cut.
- Take light passes rather than one deep cut to keep the finish clean.
- Feed boards with the grain direction the maker recommends.
- Clean the chips from the bed and rollers after each session and keep the tables free of residue.
Mistakes to Avoid
- Planing boards with embedded grit or metal, which dulls the knives.
- Taking deep cuts to save time.
- Ignoring the minimum board length in the manual.
- Buying a machine that is wider than your shop needs.
- Forgetting to leave room for support tables and dust gear.
FAQ
What is the difference between a planer and a jointer?
A planer makes the second face parallel to the first, while a jointer flattens a face or edge. Many woodworkers use both in sequence.
Do I need a dust collector?
A planer makes many chips quickly, so some form of collection helps keep the shop clean and the machine clear.
The Short Version
A good thickness planer matches your board width, offers a cutterhead you can maintain, adjusts depth clearly and connects to dust collection. Compare those features first, then the extras.
