Bosch PEX 220 A – Affordable Power Sander

Bosch PEX 220 A Random Orbit Sander
Best Sander under £50

The Bosch PEX 220 A is an excellent and affordable power sander. Perfect for decorating, woodwork and polishing jobs.

Aside from the low price, this model from Bosch has a good specification and the right details to justify the recommendation. The lightweight design and soft grip make it easy to use with one hand. And while no sander can be described as quiet, this model makes less noise than most.

Designed for working on wood, plaster, painted, varnished and polished surfaces it’s powerful enough to get the job done. And although you can’t connect a vacuum to this model, the removable dust box does a decent job.

As with all random orbital sanders, the sheets simply attach with a hook and loop fastening system and then you’re ready to go. Effective and easy to use, the Bosch PEX 220 A is a great choice for anyone who wants a decent sander for a decent price. 

SPECIFICATION: POWER: 220w | WEIGHT: 1.2kg | NOISE:77dB  | PAPER DIA: 125mm | ORBIT DIAMETER: 2.5mm | ORBITS/MINUTE: 12,000opm

Red Makita random orbital sander professional sander for serious DIY & Trade. Budget power sander for DIY
Best budget random orbital sander – Makita M9204

Makita M9204 Random Orbital Sander
Budget Sander with Good Dust Extraction

The Makita M9204 is highly rated by its owners. And it’s affordable. The Makita brand has a strong trade reputation for quality and durability. This sander is part of the MT range that’s designed to satisfy professional requirements without the price tag. 

If you’re looking for a robust and reliable sander and don’t require the features associated with a high-end professional device, then this model is a great choice. It has a couple of key benefits over the Bosch. 

More power means you can get the job done faster. And although there’s a dust collection system, this model can also be attached to a vacuum for low dust sanding. Small negatives are that the extra power does generate more noise and there’s no padding to reduce vibrations. 

Working in close proximity to anything generating above 80dB requires ear protection. Also, for your safety, the sanding disk has a brake. This means when you turn the sander off, the disk stops spinning quickly. At some point, you will be grateful for this safety feature.

If you want an affordable power sander that gives great results and is built to last – choose the Makita M9205. 

SPECIFICATION: POWER 240w | WEIGHT 1.2kg | NOISE 81dB/92dB  | PAPER DIA 125mm | ORBIT DIAMETER 2.8mm | ORBITS/MINUTE 12,000opm

Makita BO5031 Trade quality, professional workshop and site random orbital sander.
Best random orbital sander – Makita BO5031/2

Makita BO5031/2
Best Random Orbital Sander [heavy duty]

The Makita BO5031 is the best corded random orbital sander you can buy. Continual use and heavy-duty tasks are made possible by the high power output. Plus, with variable speed control, this sander is perfect for all woodworking applications and decorating jobs. 

This sander will make light work in removing multiple coats of paint from a staircase through to fine wood finishing on furniture & toys. Owners agree that the dust bag is reasonably effective, although attaching a vacuum is definitely the best solution for a dust-free working environment. 

The sanding discs are attached using a hook and loop abrasive pad. Over time the pad takes an incredible amount of punishment and is often the reason a sander fails. While it’s definitely worth looking after the pad on any sander, what’s interesting is that user experience shows Makita sanders have a good track record – the Makita hook & loop attachment works well over time.

Variable speed coupled with the correct grit paper on this random orbital sander will deliver the right results, every time. Most professionals have made the mistake of removing too much material, at some point. This can be difficult to remedy. It’s far better to start at a slow speed and then adjust up, if necessary.

Sanding is rarely a pleasant job, but with the Makita BO5031/2, you will get the job done quickly, effectively and have a professional finish to admire.

SPECIFICATION: POWER 300w | WEIGHT 1.3kg | NOISE 80dB/na  | PAPER DIA 125mm | ORBIT DIAMETER 2.8mm | ORBITS/MINUTE 4000 -12,000opm

ryobi r18ros random orbital sander cordless battery model with dust bag and soft top for vibration reduction

Ryobi R18ROS-0 18V ONE+
Budget Cordless Random Orbital Sander

This cordless sander is perfect for small to medium-sized tasks such as finishing and paint removal. 

All Ryobi tools work with an interchangeable ONE+ battery, which means you can use the same charger and batteries for multiple power tools – saving a small fortune. All battery tools offer convenience but particularly with a sander, not being tied with a cord is liberating!

Owners rate this power sander too. The padded top reduces vibrations and the dust collection is good. Plus, you can attach a vacuum to minimise dust further. 

In terms of battery choice, if you want a lighter unit go for a couple of small batteries (charge one while using the other) or alternatively go for a 5Ah battery which will give you around 50 minutes. 

Great for DIY, this sander is effective and easy to use – forget sanding by hand. 

SPECIFICATION: POWER 18v | WEIGHT 1.1kg | NOISE 95dB | PAPER DIA 125mm | ORBIT DIAMETER 2.5mm

Recommended & best buy cordless random orbital sander from Makita DBO180Z. UK
Best cordless random orbital sander – Makita DBO180Z

Makita DBO180Z
Best Cordless Random Orbital Sander

The best cordless random orbital sander is the Makita DBO180Z. There’s every reason to go cordless and this model from Makita is effective and has an excellent specification. Plus, it’s highly rated by owners. 

Are Cordless Sanders Good?

Sanders are not particularly power-hungry, so a decent-sized battery will hold its charge and give you plenty of time to get the job done. However, it’s the convenience and freedom of cutting the cord that justifies the extra cash. 

This sander is lighter than most corded models until you add the battery. Use smaller batteries if you’re after a lightweight sander (good if you’re using the device on a wall or upside down on a ceiling). Alternatively, a bigger battery will last longer.

In terms of controls, there are two push buttons. One to switch the device on and the second to adjust the speed. There are three settings – slow for polishing, medium for fine finishing and high for regular sanding. The dust bag, as with the majority of sanders is ok. But for efficient dust removal, plug in a vacuum. 

Cut the Cord

If you already have Makita batteries, buying this model is a no brainer. If you don’t currently have any cordless Makita tools, this is a great place to start. Yes, you’ll need to buy batteries in addition to the device but you’ll be choosing a great random orbital sander from an excellent brand. Plus, you will have interchangeable batteries for your next power tool purchase.

SPECIFICATION: POWER 18v | WEIGHT 1.4kg-1.7kg | NOISE 77dB  | PAPER DIA 125mm | ORBIT DIAMETER 2.8mm | ORBITS/MINUTE 7000/9000/11000opm

What Else Do I Need to Know?

How to Use a Random Orbital Sander

  1. Lighten up! Use your energy to keep the sander moving rather than applying pressure.
  2. Keep it flat. Avoid tilting the sander on any surface. Just keep it flat & keep it moving.
  3. Don’t skip sandpaper grades. Especially when working on wood, start with the appropriate grit and work through each grade (see below). You’ll get a better finish, quicker & use less sandpaper.
  4. Are imperfections not sanding out? It’s probable that the area in question is lower than the surrounding surface. Sand down the surrounding area to level off rather than attempt to press a particular spot.
  5. Try light pencil scribbles across the surface. This allows you to see where you’ve sanded and areas that you’ve missed.
  6. Protect Yourself. Use a dust mask and ear protectors.

Choosing the Right Grade sandpaper

A power sander can remove lots of material, quickly. Great, if this is what you want. However, if you’re looking for a fine finish it’s important to choose the right grit sandpaper…

  • Coarse 40/60/80 
  • Initial paint removal from timber
  • Pre-sanding of rough sawn beams or boards
  • Medium 100/120
  • Surface levelling of irregular wood (not veneer)
  • Car body paint
  • Undercoats
  • Filler
  • Fine 180/240
  • Final finishing prior to painting

The Bosch is affordable and great for occasional DIY. Ryobi has decent credentials for an entry-level cordless sander. However, if you have big plans, intend on using the sander for long durations or want additional control with variable speed go for either of the blue Makita sanders – they won’t let you down.
