In-Depth Reviews

πŸ† Best Overall

1. DeWalt DWE6423 Variable Speed Random Orbit Sander

β˜…β˜…β˜…β˜…β˜† 4.7/5

Β£135.02 Β· 280W motor Β· 8,000-12,000 OPM Β· 125mm (5") pad Β· 1.4kg Β· Variable speed dial Β· Hook-and-loop pad Β· Dust extraction

The DeWalt DWE6423 is the sander most people should buy. Its 280W motor delivers consistent power across the full speed range, and the variable speed dial lets you dial in exactly the right pace for the job - slow for fine finishing on delicate wood, faster for stripping paint or shaping edges.

The separate counterweight design keeps vibration noticeably lower than cheaper sanders, which matters when you're working on a project for hours. The hook-and-loop pad makes swapping grits a 5-second job, and the dust collection port fits standard shop vac hoses directly.

βœ… Pros

  • Powerful 280W motor handles everything from rough to fine sanding
  • Variable speed dial gives real control across different materials
  • Low vibration design - comfortable for extended use

❌ Cons

  • Dust bag is small - you'll want a shop vac connected
  • No hard case included

2. Makita BO5030 Random Orbit Sander 240V

β˜…β˜…β˜…β˜…β˜† 4.6/5

Β£88.99 Β· 300W motor Β· 12,000 OPM Β· 125mm (5") pad Β· 1.6kg Β· Constant speed control Β· Soft start Β· Dust bag included

The Makita BO5030 is built for people who sand all day. The 300W motor is genuinely more powerful than anything else in this class - it chews through material without slowing down, and the constant speed control means it doesn't sag when you lean into it.

The soft start feature is a real bonus: you can place the sander on the workpiece before pulling the trigger without the pad skating across the surface. It's not variable speed, but honestly, for most woodworking the full 12,000 OPM is what you want anyway.

This is a tool built for the long haul - Makita's build quality is evident in every part.

βœ… Pros

  • 300W motor is the most powerful in this comparison - doesn't bog down under pressure
  • Constant speed electronics maintain RPM under load
  • Soft start prevents gouging when you pull the trigger

❌ Cons

  • Heavier than DeWalt at 1.6kg
  • No variable speed - just on/off at full power

3. Bosch PEX 220 A Random Orbit Sander

β˜…β˜…β˜…β˜…β˜† 4.4/5

Β£51.99 Β· 220W motor Β· 24,000 OPM Β· 125mm (5") pad Β· 1.4kg Β· Microfilter dust box Β· Palm grip design

The Bosch PEX 220 A is proof you don't need to spend a fortune for a decent sander. At Β£51.99 you get a tool that handles 90% of DIY sanding jobs perfectly well. The microfilter dust box is a genuinely useful feature - it captures more fine dust than the basic bags on cheaper sanders, which means less floating particles in your workshop.

The compact palm-grip design makes it easy to use one-handed, especially for overhead or vertical work. Where it falls short is power - the 220W motor will struggle if you're trying to strip paint or sand dense hardwoods all day. But for furniture upcycling, paint prep, and light woodworking, it's more than adequate.

βœ… Pros

  • Genuinely good value at Β£51.99
  • Microfilter dust box collects more fine particles than basic bags
  • Compact and light - easy one-handed use overhead

❌ Cons

  • Less powerful than DeWalt and Makita - struggles on harder woods
  • No variable speed

4. Ryobi R18ROS-0 18V ONE+ Cordless Random Orbit Sander

β˜…β˜…β˜…β˜…β˜† 4.6/5

Β£67.30 Β· 18V cordless, body only Β· 20,000 OPM Β· 125mm (5") pad Β· 2.5mm orbit Β· Hook-and-loop pad Β· Dust bag included

The R18ROS-0 makes sense if you're already in the Ryobi ONE+ ecosystem - and given there are over 200 tools on that platform, plenty of people are. The freedom of cordless sanding is real: you can take it outside, up a ladder, or across the garage without hunting for an extension lead. It shares batteries with every other ONE+ tool you own, which is half the point of buying it.

Performance is solid for a cordless sander - the 20,000 OPM pad speed keeps pace with plenty of corded models on lighter work, and buyer feedback on Amazon UK is strong at 4.6 stars from more than 4,300 ratings. This listing is the body-only version, so budget for a battery and charger if you're not already in the system. The dust canister is basic but does the job for short sessions.

βœ… Pros

  • Runs on the same ONE+ batteries as 200+ Ryobi tools
  • High 20,000 OPM pad speed for a cordless sander
  • Rated 4.6/5 across 4,300+ Amazon UK ratings

❌ Cons

  • Body only - battery and charger cost extra
  • Less runtime than a corded sander for all-day work

5. DeWalt DWE6423K Variable Speed Random Orbit Sander Kit

β˜…β˜…β˜…β˜…β˜† 4.6/5

Β£219.25 Β· Same as DWE6423 + Kit box Β· 280W motor Β· 8,000-12,000 OPM Β· 125mm pad Β· Includes accessory kit

The DWE6423K is the same brilliant sander as the standard DWE6423 but comes in a proper kit box with some extras thrown in. If you're building your tool collection from scratch, the kit version makes sense - the case keeps the sander, discs, and accessories organised in your workshop or van. The included sanding discs are fine for getting started but you'll want to buy better quality ones for serious work. The Β£10 premium over the bare tool is reasonable for the storage alone.

βœ… Pros

  • Same excellent sander as the DWE6423
  • Kit box keeps everything organised
  • Includes sanding discs and accessory pack

❌ Cons

  • Β£10 more than the bare tool for the case and accessories
  • Sandpaper included is basic - you'll upgrade quickly

How to Choose a Random Orbital Sander

Power

Motor power is measured in watts for corded sanders. Anything under 200W is fine for light DIY - paint prep, sanding softwoods, small projects. For serious woodworking, look at 250W+. The Makita BO5030's 300W motor is the most powerful in this field and makes a real difference on hardwoods like oak and iroko.

Speed Control

Variable speed gives you control over how aggressive the sanding is. Lower speeds (around 6,000-8,000 OPM) are better for plastic, filler, and fine finishing. Higher speeds (12,000+ OPM) strip material faster. The DeWalt DWE6423's variable speed dial is the best implementation here - you can adjust on the fly without stopping.

Dust Collection

A sander without good dust collection fills your workshop with fine particles. Look for models with either a microfilter box (like the Bosch PEX 220 A) or a dust port that fits standard shop vac hoses. Most sanders include a basic dust bag but they fill fast - connecting a vacuum is always better.

Pad Size

125mm (5 inch) is the standard for random orbital sanders in the UK. It's the right balance of coverage and control. 150mm (6 inch) pads cover more area but are harder to manoeuvre in tight spots. Stick with 125mm unless you have a specific reason to go bigger.

Corded vs Cordless

Corded sanders give you unlimited runtime and consistent power - they're the right choice if you're working in a workshop with power nearby. Cordless (like the Ryobi R18ROS-0) is convenient for quick jobs, ladder work, or taking outside. But expect shorter runtime and less power than equivalent corded models.

Frequently Asked Questions

What's the difference between a random orbital sander and a regular orbital sander?
A random orbital sander spins and oscillates at the same time - the pad moves in a random pattern. This prevents swirl marks and gives a smoother finish. A regular orbital sander (or finishing sander) just vibrates in a fixed pattern, which can leave visible marks. For woodworking, always choose random orbital.
What grit sandpaper should I use for woodworking?
Start with 60-80 grit for rough shaping and material removal. Move to 120-150 grit for general sanding. Finish with 180-240 grit for a smooth surface ready for painting or varnishing. For fine furniture, you might go up to 320 grit. Always work through the grits in order - skipping grits leaves scratches that show through the finish.
Can I use a random orbital sander to remove paint?
Yes, with the right grit (60-80) a random orbital sander is effective for paint removal on flat surfaces. But be careful on lead paint - the fine dust is hazardous. Always wear a mask and connect dust extraction. For curved or detailed surfaces, a chemical stripper or heat gun might be better options.
Do I need variable speed on a random orbital sander?
Not essential, but useful. Variable speed lets you slow down for plastics, fillers, and fine finishing where high speed might melt or burn the surface. If you mainly sand wood, a single-speed sander at 10,000-12,000 OPM works fine. If you work with different materials, variable speed is worth the extra cost.
What's the best random orbital sander for a beginner?
The Bosch PEX 220 A at around Β£52 is the best starting point. It's affordable, lightweight, and good enough for most DIY projects. If you're sure woodworking will be a long-term hobby, skip straight to the DeWalt DWE6423 - it'll last for years and handle anything you throw at it.
Can random orbital sanders be used for wet sanding?
Most random orbital sanders are not designed for wet sanding. Water can get into the motor bearings and dust extraction system, causing damage and creating an electrical safety risk. If you need to wet sand, use a manual block or a dedicated wet/dry sander.

Final Verdict

After comparing 5 random orbital sanders across different price points and use cases, the DeWalt DWE6423 comes out on top for most people. It combines genuine power with useful variable speed control, low vibration, and solid build quality at a fair price.

If you're a professional or sand all day, the Makita BO5030's extra power and constant speed electronics make it worth the premium. For DIY users on a budget, the Bosch PEX 220 A does everything most people need for around Β£52.

And if you're already invested in the Ryobi ONE+ system, the R18ROS-0 is a convenient cordless option that shares your existing batteries. Whatever your budget, there's a sander here that will make your woodworking projects faster and the results smoother.
