A Complete Guide on the Best Sanders for Refinishing Furniture! (2018)

While sanding is not all too popular in the furniture refinishing business, it is still an essential technique that helps prevent unnecessary wastage while giving the furniture in question a fresh look.

The most recommended sander types are electric in nature, among which there are three prominent sub-types: orbital, belt, and random-orbit sanders. Armed with apt abrasives, you can smooth-sand any wooden surface just the way you want it.

Why A Sander for Refinishing Furniture

First off, a safety note… Sanding, much like its name suggests, can generate enormous amounts of dust. Though several modern models have dust collection bags or ports to help mitigate polluted residues, a dual cartridge respirator or a simple face mask can keep your lungs safe from harm.

Speed, strength, and power define belt sanders whose design includes a motor that fires up a rear drum that in turn rotates a belt. The fore drum turns freely to compensate. Flat board smoothing springs to mind for belt sanding techniques. This type is capable of smoothing narrow edges on these and other boards. You can also use it to remove old stains, finishes, varnishes, and paints. Its four standard sizes include 3x18, 3x21 (most popular), 3x24, and 4x24; all measured in inches. While it is difficult to control, in the right hands belt sanders can perform amazing heavy duty refinishing tasks.

Comparatively lighter and manageable are orbital sanders, which are easier to use with less fear of damage. Sharp-edge rounding and super-smooth wood sanding are ideal for this tool. You can also use it to knock down dry varnish and paint coats, not to forget sand off solidified wood putty. Also termed ‘quarter-sheet sanders’, they are designed with a pair of spring-loaded clamps that hold sandpaper against the device and spin or orbit in small circles; hence the name.

A hybrid combination of the two tool types mentioned above are random-orbit sanders, which look more like orbital sanders than their belt-wearing cousins. If you see a square sanding pad, it is an orbital sander, while a rounded pad is part of the random-orbit’s identity. The name gives away its purpose: the circular pad can move in random orbits, while a square one needs you to push it in a certain direction. From smooth-sanding tasks to stock removal, the one disadvantage with this tool type is that it cannot refinish wood faster than a belt sander, but it is leagues more versatile. The grip-designs are more intuitive, the diameter pads are a welcome 5 or 6 inches, and most models are compatible with sticker-like PSA (pressure sensitive adhesive) abrasives as well as Velcro discs.

Top 5 Best Sanders for Refinishing Furniture – Reviews

1. Bosch 1250DEVS 6-1/2-Amp 6-Inch Random Orbit Sander

Some of the niftiest features have gone into this interesting random orbit sander from Bosch.At 5.3 pounds, it is manageably heavy. At the turn of a switch, you can access Turbo Mode; resulting in speedier stock removals (it runs the machine at five times the regular setting). There is also Random Orbit Mode for attractive fine-swirl sanding.

Pad speed does not fluctuate, thanks to constant response circuitry. Not only does this feature stay active under heavy workloads but it also prevents overloading on the 1250DEVS’s internal mechanics.

You have the option of soft starting the device, meaning remarkably reduced torque levels upon start-up. Variable speed settings are then at your disposal so you can match a speed to the task at hand; some professional experience will be required to best understand how to use this particular feature.

The powerful 6½-amp motor is designed to improve the 1250DEVS’s lifespan while also promoting heavy duty sanding capabilities. To top it off, a vacuum port is present to mitigate dust accumulation during sanding. The brilliant integral pad dampening system takes care not to leave any distinct swirl marks on wood surfaces.

At 3.4 amps, the BoschOS50VC is one of the more powerful orbital sanders on the market. The ampere setting certainly grants you maximum sanding speeds and enhanced stock removal rate.

The micro-filter dust canister is translucent and comes equipped with integrated screen-off cap and paper filter. This improves on most such designs and helps keep dust accumulation to a minimum (even zero) while allowing you the chance to perform quick emptying of the can. Also included is a vacuum hose with airflow control.

This sander’s exquisite vibration control technology is worth detailing here. Unique to Bosch, this suspension system is designed to reduce vibrations to a bare minimum. This directly influences your comfort and handling abilities.

You can take excellent advantage of the variable speed dial, using which you can match speed and power to the task at hand to get the best possible performance out of the BoschOS50VC.​

Factors To Consider In Die Grinder Selection

We have already covered several key points concerning the three different types of sanders available today; scroll up to the introduction for more. We shall now confidently relegate ourselves to explaining how best you can shop for sanders, based on the furniture project at hand.

1. Belt Sanders

Use belt sanders for dressers and tables, especially if there is plenty of paint or varnish refinishing to be done, so the furniture piece can be reverted to its raw wood format. You might end up creating gouges in the surface of the wood or ‘brr’ marks – this is most common with DIY-ers. In these instances, you can indeed re-sand the surface, but a little practice can go a long way. You can also smooth out rough segments of trim or timber.

2. Orbital &Mouse Sanders

Mouse sanders can perform back and forth motions while the orbital kind goes round and round. Based on what sort of technique you plan to use, get the right sander to go. Use these for lightly varnished or medium-painted wood surfaces. Remember that the sanding grit moves in a circle, which means there is a possibility that the tool will leave behind rounded grooves or marks. A mouse or finishing sander will help eliminate this afterwards. Since the mouse sander performs straight motions, your technique can stay along with the grain of the wood instead of going against it.

3. Sanding Gloves

These can prove enormously useful; in fact they complement your sanding tools quite well. The hand-shaped grit can stick to the Velcro on the gloves and grant you improved traction. As a result, you can create some of the smoothest surfaces. Unlike holding actual sandpaper, this one will not slip away as easily. The 240 and 120 models from the ‘Sandi Hands’ brand are worth checking out for hard to access spots on your furniture. 240-320 light grit versions are ideal for distressing signs or painted surfaces. For ultra-smooth finishes, grab the higher grits starting at the 400 mark.

4. Why am I doing all this again?

The core aim of sanding is to help extend the lifespan of the furniture in question, meaning longer lasting paint and varnish jobs and lesser accumulation of grime, dirt, and whatnot. Since this will certainly inspire you to hang on to that furniture piece in lieu of turning it into firewood or recyclable material, we can safely say that you have plenty of cost-effective restyling options where refinishing is concerned.


We are indeed spoiled for choices and it took a while for us to decide which sander to recommend as our best in class. While professionals usually prefer belt sanders, the competition seems to have caught up to these aggressive little ‘sand monsters’. The best sander for refinishing furniture is: The BoschOS50VC. No-3 on our list, this orbital sander has won our respect and praise. Click here for more information on this.

Its Supreme Paper Clamping System is, in our opinion, deserving of awards. The 3.4 amp motor is more than ideal for several different kinds of sanding and refinishing tasks. At 6 pounds, it is also ideally weighted. Excellent dust collection and vibration-reduction designs complement the OS50VC’s clamping mechanism and hole punching plate. This is all in all a glorious sander for furniture refinishing.
