Planer Thicknessers
A thickness planer squares up rough timber and brings boards down to a consistent size for joinery, fitting and workshop prep without the usual faff.
If you're sick of twisted stock, proud edges and boards that never quite match up, this is the kit that sorts it. A good thicknesser saves time on repeat cuts, cleans up sawn timber properly, and gives you reliable sizes for doors, framing, cabinets and bench work. If you're setting up a small workshop or need a portable thicknesser for site jobs, pick the machine that matches the timber you actually run through it and get the job moving.
What Are Thickness Planers Used For?
- Bringing rough sawn timber down to a clean, repeatable thickness saves a lot of hand fettling when you are building frames, benches, shelving or joinery packs.
- Cleaning up reclaimed or stored timber helps chippies and workshop teams get rid of saw marks, slight cup and weathered faces before cutting to final size.
- Matching boards for cabinet runs, worktops and built-ins makes fitting easier, because you are not fighting different thicknesses across the same job.
- Prepping softwood and hardwood stock in a small workshop gives you straighter, more usable material for accurate machining, fixing and final assembly.
- Running repeat pieces through a portable thickness planer is handy on snagging and second fix work when bought-in timber needs trimming back to suit an existing opening or detail.
Choosing the Right Thickness Planer
Sorting the right one is simple: match it to the timber you run every week, not the one oversized board you might machine once.
1. Benchtop or Bigger Workshop Machine
If you are short on space or moving the machine between jobs, a benchtop thicknesser makes more sense. If you are feeding long lengths all day in a fixed workshop, go bigger and heavier so the machine stays planted and gives steadier results.
2. Width and Depth Capacity
Check the widest and thickest timber you actually use. Do not buy a machine that only just covers your usual stock, because rough timber can vary and you will soon get fed up turning work away or ripping boards down first.
3. Feed Rate and Finish
If you are batching out clean stock for visible joinery, look at feed quality and finish, not just headline power. A faster pass is fine for rough prep, but for final faces you want a machine that leaves less tearing and less sanding afterwards.
4. Dust Collection Matters More Than Most Think
Do not ignore extraction. Thicknessers throw out a serious volume of shavings, and if you do not manage it properly the machine clogs, the finish suffers and your workshop turns into a mess in no time.
Who Uses These on Site and in the Workshop?
- Chippies use thickness planers when they need timber at a true, repeatable size for first fix stud parts, second fix trim, built-in storage and bench joinery.
- Joiners and cabinet makers swear by a wood thicknesser for bringing rough stock to final dimension before cutting housings, lippings, doors and face frames.
- Shopfitters use a small planer thicknesser to tidy bought-in boards and get clean, matching material when fitting counters, display units and trims on tight timescales.
- Maintenance teams keep a bench top planer thicknesser in the workshop for repair work, packers, replacement sections and one-off timber jobs that do not justify sending material away.
- Serious DIY users and small workshop owners reach for a portable thicknesser when they want better results from sawn timber without taking up the space of a full floor-standing planer machine.
The Basics: Understanding Thickness Planers
A thickness planer does one main job: it takes timber that is already reasonably flat on one face and machines it down to a consistent thickness. That matters because accurate stock makes every job after it quicker.
1. It Cuts the Top Face to Match the Set Height
You wind the machine to the thickness you want, feed the board through, and the cutter head removes material from the top. The result is timber that comes out the far end at a controlled, repeatable size for cleaner fitting and assembly.
2. It Is Not the Same as Face Jointing
A thicknesser does not fully correct badly twisted timber on its own. It follows the board as it passes through, so the best results come when one face is already flat or at least prepared well enough to feed true.
3. Shallow Passes Usually Give Better Results
Taking too much off in one hit is where you get sniping, tear-out or extra strain on the machine. Steady passes keep the finish cleaner, the motor happier and the board easier to control.
Thicknesser Accessories That Save Time in the Workshop
A few sensible extras make a thickness planer cleaner to run, easier to support and cheaper to keep working.
1. Planer & Thicknesser Blades
Keep spare Planer & Thicknesser Blades to hand. Blunt blades leave ridges, tear grain and make the motor work harder, which is the sort of slow-burn problem that ruins a decent day in the workshop.
2. Dust Extractors & Vacuums
Hook it up to proper Dust Extractors & Vacuums. You will be grateful when chips are not piling up under the outfeed, clogging the hood or covering every other bench in the place.
3. Saw Stands
A solid set of Saw Stands helps support longer boards going in and out. That stops the timber dropping, dragging and marking, especially when you are working alone with door stock or long softwood lengths.
Choose the Right Thickness Planer for the Job
Use this as a quick guide before you pick a machine.
| Your Job | Thickness Planer Type | Key Features |
|---|---|---|
| Occasional workshop prep and light joinery | Portable benchtop thicknesser | Compact footprint, straightforward depth setting, easy storage and enough capacity for regular softwood and board stock. |
| Small workshop making cabinets, trims and furniture parts | Bench top planer thicknesser | Better consistency on repeat passes, decent width capacity and stable setup for regular use through the week. |
| Site fitting where timber often needs sizing to suit | Portable thickness planer | Easier to move, quicker to set up and suited to smaller quantities without taking over the van or workshop. |
| Long boards and frequent machining in a fixed space | Larger workshop thicknesser | More support, steadier feed, stronger build and less movement when running heavier or longer timber. |
| Cleaning rough sawn timber before final joinery work | Thicknesser with good extraction setup | Consistent cut depth, reliable feed and proper chip clearance to keep finish quality up and blockages down. |
Common Buying and Usage Mistakes
- Buying on maximum width alone is a common mistake. If the machine is too light or underpowered for the timber you actually use, you will end up with poor finish, slow progress and more frustration than it is worth.
- Trying to remove too much material in one pass usually ends in tear-out, sniping or a bogged-down motor. Take steady cuts and let the machine do the work properly.
- Using a thicknesser on badly twisted or filthy timber without checking it first is asking for trouble. Stones, grit and hidden fixings wreck blades fast, and badly distorted stock will not come out right just because it went through the machine.
- Skipping dust extraction is a false economy. Shavings build up quickly, the work area becomes a mess and the machine can start feeding poorly or blocking when you are halfway through a run.
- Ignoring blade condition costs you time every time. If the cutter is leaving ridges or tearing grain, sort the blades before blaming the timber or forcing another pass.
Benchtop Thicknesser vs Planer Thicknesser vs Handheld Planer
Benchtop Thicknesser
Best if you need consistent board thickness without giving up loads of workshop space. It is the practical choice for joinery prep, smaller workshops and repeat sizing, but it still needs reasonably flat stock to start with.
Planer Thicknesser
This is the more complete setup if you want to flatten one face and then thickness the board on the same machine. Better for serious timber prep, but larger, heavier and less suited to occasional site use.
Handheld Planer
A handheld planer is for trimming doors, easing edges and quick fitting work, not machining boards to a repeatable finished thickness. Useful on site, but it will not replace a proper thicknesser in the workshop.
Which One Makes Sense?
If your main issue is getting timber all the same size, buy a thickness planer. If you need full stock prep from rough timber, look at planer thicknessers. If you are only shaving a door or lipping, stick with handheld Planers.
Maintenance and Care
Keep the Bed and Rollers Clean
Brush off chips and resin after use so boards feed properly and do not pick up marks. Built-up waste on the bed or rollers is one of the quickest ways to spoil accuracy.
Watch Blade Condition
If cuts start looking furry, ridged or torn, inspect the blades straight away. Fresh blades protect the finish, reduce strain on the motor and stop you sanding away half the job afterwards.
Empty Extraction and Clear Chutes
Do not let shavings compact in the hood or outlet. A blocked extraction path affects cut quality and can cause feeding problems that look like machine faults when they are not.
Store It Dry and Covered
Keep your bench thicknesser somewhere dry to stop rust building on the table and height posts. A simple cover helps keep workshop dust and damp off the working parts.
Repair or Replace at the Right Time
Blades are normal wear items, but damaged feed parts, noisy bearings or poor adjustment are signs to sort the machine properly. If it will not hold settings or feed straight, fix it before it starts ruining timber.

Thickness Planer FAQs
What is the point of a thickness planer?
It brings timber down to a consistent thickness across the full board, which is what you need for decent joinery, fitting and repeat work. In plain terms, it saves you fighting mismatched stock and gives you cleaner, more accurate material to build with.
What's the difference between a thicknesser and a planer?
A thicknesser machines a board to an even thickness. A planer, especially a handheld one, is more about trimming, flattening edges or taking material off locally. A planer thicknesser combines both workshop jobs, but a standard thickness planer is mainly for sizing timber accurately.
What thickness can a benchtop thicknesser take?
It depends on the model, but most benchtop machines handle common joinery and workshop stock comfortably. Always check both the maximum board height and the minimum finished thickness, because that tells you whether it will cope with your usual softwood, hardwood or sheet-derived stock.
Can you thickness rough sawn timber?
Yes, but be sensible with it. Rough sawn timber can be thicknessed once it is clean and reasonably prepared, but badly twisted, dirty or nail-ridden boards are asking for poor finish and wrecked blades. Check it first and take shallow passes.
Do I need dust extraction for a thicknesser?
Yes, in practice you do. Thicknessers throw out a serious amount of chips and shavings, and without extraction the machine clogs, the finish can suffer and your workshop becomes a tip very quickly. Proper extraction is not a luxury on this sort of kit.
Will a portable thickness planer cope with hardwood?
Yes, most decent portable machines will handle hardwood, but you need sharp blades and sensible cut depth. Do not try to hog too much off in one pass or you will slow the feed, mark the timber and put unnecessary strain on the motor.
