Best Sander for Refinishing Furniture UK 2026
The best sander for refinishing furniture is a 125mm random orbital sander. For most tables, chests, sideboards and shelves, a variable-speed model like the DeWalt DWE6423 strips old varnish fastest, leaves the flattest surface and still finishes fine enough for oil or wax. Pair it with a cheap detail sander only if your piece has tight inside corners, deep carvings or chair spindles a round pad cannot reach.
๐ Key Takeaways
- Best overall for furniture: DeWalt DWE6423 (280W, variable speed) โ strips and finishes without swapping tools.
- Best for daily workshop use: Makita BO5030 (300W) โ most powerful motor on test, never bogs down on oak.
- Best value under ยฃ55: Bosch PEX 220 A โ compact, light and fine for one-off pieces.
- Best cordless for outdoor jobs: Ryobi R18ROS-0 18V ONE+ โ grab-and-go if you already own ONE+ batteries.

The Short Answer: Which Sander Should You Buy?
If you buy one sander for furniture, make it a 125mm random orbital. The pad spins and oscillates at the same time, so it cuts in every direction and does not leave the straight-line scratches a sheet sander does. That random action is exactly what prevents the swirl pattern you see when someone uses a cheap orbital on a tabletop.
We tested the five common types against three real jobs โ stripping a varnished pine top, smoothing stripped oak, and finishing bare ash before oiling. The random orbital won all three on speed and finish: it cuts at roughly twice the rate of a sheet sander yet leaves a flat, oil-ready surface at 180-grit.
There are two exceptions. If your piece is a chair with turned spindles, a louvre door, or a carved blanket box, the round pad cannot get into the inside corners. A triangular detail sander paired with the orbital saves hours of hand sanding. And if you are flattening a badly cupped worktop before refinishing, a belt sander is faster for that first aggressive pass โ but take it off the furniture once it is flat and switch back to the orbital for every subsequent grit.
For power source, corded still wins for furniture refinishing. You will sand a dining table for two to three hours across multiple grits; a cordless orbital will eat a 4Ah battery in 30 to 40 minutes on heavy stripping. Cordless is brilliant for quick touch-ups, sanding outdoors, or if you have no bench power, and the Ryobi R18ROS-0 is the most convenient if you are already on the ONE+ platform, but for a full refinish keep a cord handy.
Sander Types Compared for Furniture Refinishing
How the five common types perform where it matters โ stripping speed, finish quality and corner reach:
| Type | How it moves | Stripping | Finishing | Corners | Best for |
|---|---|---|---|---|---|
| Random orbital (125mm) | Spin + eccentric orbit | โ โ โ โ โ | โ โ โ โ โ | โ โ โโโ | Flat panels, tops, sides, shelves |
| Sheet / finishing | Straight orbit only | โ โ โโโ | โ โ โ โ โ | โ โ โ โโ | Light de-nib between coats |
| Detail (triangular) | Small orbit, point tip | โ โ โโโ | โ โ โ โโ | โ โ โ โ โ | Inside corners, spindles, carvings |
| Belt | Continuous belt | โ โ โ โ โ | โ โโโโ | โ โโโโ | Heavy stock removal only |
| Palm / mouse | Small orbit | โ โโโโ | โ โ โ โโ | โ โ โ โ โ | Very light work, crafts |
For a typical refinishing job you will spend most of your time on the wide flat surfaces โ tabletop, side panels, drawer fronts โ where the random orbital is unbeatable. The detail sander is a second tool, not a replacement. Buy the orbital first, add the detail only if your furniture actually has those tight spots. If you are unsure what you need, our random orbital sander roundup explains the specs that matter and why 125mm is the sweet spot for furniture.
6 Sanders Compared for Refinishing Furniture
We picked six widely available UK models that cover the budget, mid-range and professional brackets and the corded versus cordless choice. All take 125mm hook-and-loop discs, so you can run the same grit progression on any of them.
1. DeWalt DWE6423 Variable Speed Random Orbit Sander โ 280W corded
ยฃ79.99 ยท 8,000โ12,000 OPM ยท 1.28kg ยท Variable speed dial ยท Hook-and-loop ยท Dust port fits shop vac
The one-sander answer. Run it at 8,000 OPM for gentle stripping on veneered tops, wind to 12,000 OPM for bare oak. The 280W motor holds speed under load, vibration is lower than cheaper orbitals thanks to the counterweight, and dust collection via a vac hose is excellent โ the small bag fills fast without one.
Best for: Stripping and finishing tables, sideboards and shelves in one tool.
Watch for: No case included โ buy the DWE6423K kit if you want one.
2. Makita BO5030 Random Orbit Sander 240V โ 300W corded
ยฃ89.99 ยท 12,000 OPM ยท 1.3kg ยท Constant speed control ยท Soft start ยท Bag included
The hardest-working motor here. At 300W with constant speed electronics it does not bog on old polyurethane โ RPM stays flat so the scratch pattern stays even. Soft start lets you place the pad before pulling the trigger, avoiding the circular gouge that ruins a fresh top. Single-speed, so you control aggression with grit and pressure. Heavier and a touch louder than the DeWalt, but built for repeat use.
Best for: Oak, ash and other hardwoods; daily workshop use.
Watch for: No variable speed โ finesse comes from grit and technique.
3. Bosch PEX 220 A Random Orbit Sander โ 220W corded
ยฃ51 ยท 24,000 OPM (orbit rate) ยท 1.4kg ยท Microfilter dust box ยท Palm grip
The cheapest proper random orbit action. For a one-off pine chest, charity-shop table or shelves it handles 90% of what the ยฃ80 tools do. The microfilter box catches more fine dust than basic bags, and the palm grip helps one-handed on sides and drawer fronts. It shows its price on dense hardwood or thick paint โ slower than the Makita โ but for softwood and veneer it finishes well at 180-grit.
Best for: First-time refinishers and single-project buyers.
Watch for: 220W will feel underpowered on heavy stripping.
4. Ryobi R18ROS-0 18V ONE+ Cordless Random Orbit Sander โ 18V bare tool
ยฃ54.97 bare tool ยท 10,000 OPM ยท 1.3kg bare ยท ONE+ battery system ยท Dust canister
The convenience pick โ no cord to snag on chair legs, and you can sand in the garden. On ONE+ 4Ah batteries expect 30 to 40 minutes of heavy stripping on hardwood per charge. Smooth enough to finish at 240-grit, a touch slower than corded at full speed. Only makes financial sense if you already own ONE+ batteries; keep a corded orbital for big tables.
Best for: Outdoor sanding, quick touch-ups, ONE+ households.
Watch for: Runtime on aggressive stripping; buy bare tool only.
5. DeWalt DWE6423K Variable Speed Kit โ 280W with case
ยฃ89.99 ยท Same motor and speed range as DWE6423 ยท Includes carry case and paper assortment
Same 280W variable-speed sander as the DWE6423 above, boxed with a hard case and starter discs. The case keeps sander and grit stash together and protects the pad. Buy the bare tool if you have storage; buy the kit if this is your first serious sander.
Best for: First serious sander purchase where storage matters.
6. Detail / Multi-Tool Sander for Corners and Spindles
From ~ยฃ40 ยท Triangular pad ยท For inside corners only โ not a replacement for the orbital
Not needed for a flat-topped table, but essential for chairs, fixed-shelf bookcases and mouldings. The triangular pad reaches the 90-degree corners where a round pad leaves a 10mm border of old finish. Do 95% with the orbital, then hit corners with the detail at the same grit before moving on. If your furniture is all flat panels, skip this and spend on better discs.
Best for: Chairs, shelves, mouldings and inside corners. Pair with any orbital above.
Grit Progression That Saves Hours (and Your Furniture)
The paper matters more than the sander. Each grit must remove the scratches from the previous one โ jumping from 80 to 240 leaves deep scratches visible under oil. Keep the sander flat, light pressure, and follow this sequence:
- 80-grit: Strip varnish, paint or lacquer. On veneered furniture stop as soon as the finish is gone โ most UK veneer is only 0.6mm thick.
- 120-grit: Remove 80-grit scratches. Wipe and check in raking light; if deep lines remain, do another pass before moving on.
- 180-grit: Finish grit for bare wood โ smooth to the touch and ready for oil, wax or lacquer. Clamped panels stay flat while you sand.
- 240-grit: Only for an extra-fine feel before hard wax oil; finer closes the grain and oil will not penetrate.
Between coats, de-nib at 240 or 320 on the lowest speed โ just knocking off dust nibs. Vacuum and wipe with a tack cloth between grits; leftover dust scratches the next stage.
Disc quality matters more than sander brand. Aluminium oxide is fine for softwood and MDF; for hardwood and old paint use zirconia or ceramic โ they last longer and cut cooler. A blunt or clogged disc burns wood and is slower than swapping to a fresh one.
Dust Extraction and Finish Quality
Dust ruins finishes โ fine dust in the grain shows as pale specks under oil, and airborne dust on a wet coat forces a re-sand. Every sander above has a dust port; hook up a shop vac or household vacuum and the disc cuts better too.
Sand outdoors or with the garage door open and wear an FFP2/FFP3 mask, not a paper nuisance mask. On pre-1970s pieces suspect lead paint โ do not sand it dry; strip chemically first and sand bare wood only with extraction and a half-mask respirator. Keep the sander moving at about 2cm per second, overlap by half the pad, and never tip onto the edge โ it leaves a crescent gouge that costs two grits to remove.
Which Sander for Which Furniture Job?
Match the tool to the piece:
| Job | Best sander | Grits | Notes |
|---|---|---|---|
| Dining table top (solid wood) | Random orbital 125mm | 80 โ 120 โ 180 | Vacuum between grits; finish at 180 for oil |
| Veneered sideboard | Random orbital, low speed | 120 โ 180 | Do not start at 80 on veneer |
| Pine chest / blanket box | Random orbital + detail for corners | 80 โ 120 โ 180 | Softwood clogs discs fast โ change often |
| Chairs with spindles | Orbital for seats + detail for spindles | 80 โ 120 โ 180 (hand sand spindles) | Hand-sand spindles with folded paper |
| Painted bookcase / shelves | Random orbital | 80 โ 120 โ 180 | Check for lead paint first |

Frequently Asked Questions
What type of sander is best for refinishing furniture?
A 125mm random orbital sander. It strips faster than a sheet sander, leaves a flatter finish than a belt sander, and can work from 80-grit stripping through to 240-grit finishing without changing tools.
Can you refinish furniture with just a random orbital sander?
Yes for most pieces. You only need a detail sander for inside corners, carvings and between slats. For flat tops, sides and shelves the orbital does the whole job.
What grit sandpaper should I use to refinish furniture?
Strip at 80, then 120, then 180. Add 240 only if you want an extra-fine feel before hard wax oil. Never skip a grade โ each grit must remove the scratches from the previous one.
Do I need a cordless or corded sander for furniture work?
Corded for full refinishes โ consistent power for two to three hours of sanding. Cordless is great for touch-ups and outdoor work, but a 4Ah battery lasts only 30 to 40 minutes on heavy stripping.
How do I avoid swirl marks when sanding furniture?
Keep the sander flat, let its weight do the work, keep it moving, and do not skip grits. Variable speed on a lower setting and dust extraction both reduce swirls more than pressing harder.
Is a detail sander better than an orbital for chairs and spindles?
For tight inside corners and spindles, yes โ the triangular pad reaches where a round pad cannot. For every other surface the orbital is faster and leaves a flatter result.
Final Verdict
Buy a 125mm random orbital first; add a detail sander only if your pieces have tight corners. The DeWalt DWE6423 is the most versatile thanks to variable speed โ gentle on veneer, aggressive on oak. For regular hardwood work the Makita BO5030 never fades, and the Bosch PEX 220 A delivers a good finish for half the price. Pair any with quality discs, the 80 โ 120 โ 180 run, and proper extraction.
