Bosch PEX 300 AE

Best Overall
4.6 / 5
Power300W
Orbit Dia.2.5mm
Pad Size125mm
Speed12,000-24,000 OPM
Pros
  • Excellent dust extraction via microfilter
  • Variable speed control for different materials
  • Bosch build quality and 2-year warranty
Cons
  • Only 2.5mm orbit stroke
  • Not the most powerful at 300W

The Bosch PEX 300 AE is the benchmark for budget random orbital sanders. It features a 300W motor with variable speed control, allowing you to adjust from 12,000 to 24,000 orbits per minute. The 125mm pad is standard, and the microfilter dust box is one of the best in class, keeping your workspace cleaner than most competitors.

Owner reviews consistently praise its low vibration and comfortable grip, making it ideal for extended sanding sessions. While the 2.5mm orbit is smaller than some, it delivers a finer finish, which is perfect for paint preparation and fine woodworking. It is a reliable workhorse that justifies its place as the top pick.

Expert take: The PEX 300 AE offers the best balance of performance, dust control, and durability at this price point. It is the safest choice for anyone wanting a sander that will last.

Draper 450W Random Orbital Sander

Best Budget Power
4.2 / 5
Power450W
Orbit Dia.3.0mm
Pad Size125mm
Speed12,000-24,000 OPM
Pros
  • High 450W motor for aggressive sanding
  • 3.0mm orbit for faster material removal
  • Very affordable price point
Cons
  • Dust box is less effective than Bosch
  • Higher vibration levels reported

The Draper 450W is the power champion in the budget category. With a 450W motor and a 3.0mm orbit, it removes material faster than most sanders at this price. It is a great choice for stripping paint or rough sanding where speed is more important than a mirror finish.

Owner feedback highlights its raw power but notes that it is heavier and vibrates more than the Bosch. The dust collection via the included box is adequate but not exceptional. For DIYers on a tight budget who need to tackle heavy-duty jobs, the Draper offers unbeatable value for the power output.

Expert take: If you need to remove a lot of material quickly and don't mind a bit more vibration, the Draper 450W is the most powerful sander you can get for under £50.

Ryobi ROS300

Best for DIY Enthusiasts
4.3 / 5
Power300W
Orbit Dia.2.5mm
Pad Size125mm
Speed11,000-22,000 OPM
Pros
  • Good dust collection with microfilter
  • Comfortable rubberised grip
  • Part of the Ryobi One+ ecosystem
Cons
  • No variable speed control
  • Lower max OPM than competitors

The Ryobi ROS300 is a solid corded sander that fits perfectly into the Ryobi ecosystem. It features a 300W motor and a microfilter dust box that works well for general DIY. The rubberised grip is comfortable, and the sander is well-balanced for one-handed use.

Owner reviews are positive, with many appreciating the build quality and dust extraction. The main downside is the lack of variable speed, which limits its versatility on different materials. It is a straightforward, reliable sander for home users who already own Ryobi tools and want consistency in their workshop.

Expert take: A dependable choice for Ryobi fans. The lack of variable speed is a compromise, but the overall build and dust collection make it a strong contender.

Bosch PEX 220 A

Best Lightweight
4.4 / 5
Power220W
Orbit Dia.2.5mm
Pad Size125mm
Speed12,000-24,000 OPM
Pros
  • Very lightweight at 1.1kg
  • Low vibration for fatigue-free use
  • Bosch reliability and warranty
Cons
  • Only 220W motor, less powerful
  • Dust box is smaller than PEX 300

The Bosch PEX 220 A is the lightweight champion of the budget category. Weighing just 1.1kg, it is incredibly easy to manoeuvre and perfect for overhead work or long sanding sessions. It still features a variable speed dial and a 125mm pad, making it versatile for fine finishing.

Owner reviews are excellent for its comfort and low vibration, though some note it struggles with heavy material removal due to the lower 220W motor. It is best suited for fine sanding and paint preparation where a light touch is needed. For delicate work, this is the best choice under £50.

Expert take: If comfort and low fatigue are your priorities, the PEX 220 A is unbeatable. Just don't expect it to strip paint quickly.

Einhell TE-OS 18/130

Best Cordless
4.1 / 5
Power18V (Bare Tool)
Orbit Dia.2.5mm
Pad Size125mm
Speed6,000-22,000 OPM
Pros
  • Fully cordless convenience
  • Variable speed trigger
  • Part of Einhell Power X-Change family
Cons
  • Requires battery and charger (sold separately)
  • Less consistent power than corded models

The Einhell TE-OS 18/130 brings cordless freedom to the budget category. As a bare tool, it fits the Einhell Power X-Change ecosystem, meaning it shares batteries with other Einhell tools. It features a variable speed trigger and a 125mm pad, offering decent versatility for on-the-go sanding.

Owner reviews appreciate the convenience but note that battery life can be a limitation for larger projects. The power is adequate for light to medium sanding, but it won't match the consistent output of a corded sander. For quick touch-ups and jobs without a power socket, this is the best option under £50.

Expert take: A great entry point into cordless sanding for Einhell users. It is convenient but best kept for smaller tasks due to battery constraints.

What to check before buying a random orbital sander under £50

Power (Watts): For corded models, look for at least 250W for general DIY. 300W is the sweet spot for balance between power and control. Higher wattage like 450W is better for aggressive material removal but can be heavier.

Orbit diameter: A 2.5mm orbit is standard for fine finishing and produces a smoother surface. A 3.0mm orbit removes material faster but leaves a slightly coarser finish. Choose based on your primary use: fine sanding or stock removal.

Dust extraction: A good dust collection system is crucial for health and visibility. Look for models with a microfilter dust box or the ability to connect to a vacuum cleaner. The Bosch PEX 300 AE is the class leader here.

Variable speed: This feature allows you to adjust the OPM (orbits per minute) for different materials. Lower speeds for plastics and paint, higher speeds for wood. It adds versatility and is worth having.

Pad size: 125mm (5-inch) is the universal standard for random orbital sanders. It offers a good balance of coverage and control, and sandpaper is widely available and cheap.

Mistakes to avoid

Ignoring dust collection: A sander without good dust extraction will clog sandpaper quickly and create a messy, unhealthy workspace. Prioritise models with a microfilter box or vacuum port.

Buying too much power: A 450W sander sounds great, but it is heavier and vibrates more. For fine finishing, a 300W model with a smaller orbit is actually better. Match the tool to the job.

Forgetting the pad: Check that the pad is hook-and-loop (Velcro) compatible. Most are, but some very cheap models use a different system. Stick with 125mm hook-and-loop for ease of use.

Not checking the warranty: Budget tools can fail. A 2-year warranty from Bosch or Ryobi offers peace of mind. Avoid no-name brands with no warranty support.

FAQs

Can I use a random orbital sander for polishing?

Yes, but only with a foam polishing pad and appropriate compound. The random orbit action is safe for paint, but you need a variable speed sander set to a low speed.

What is the difference between a random orbital sander and a palm sander?

A random orbital sander moves in a random pattern, preventing swirl marks. A palm sander vibrates in a fixed pattern and can leave marks. Random orbital is better for a smooth finish.

Is a cordless random orbital sander under £50 any good?

Yes, but only for light to medium tasks. The Einhell TE-OS 18/130 is a good example, but you need to buy a battery separately. Corded models offer more consistent power for the same price.

What size sandpaper do I need for a 125mm pad?

You need 125mm hook-and-loop sanding discs. They are widely available in various grits from 40 (coarse) to 400 (fine). Always buy the correct size for your pad.

How do I reduce swirl marks from a random orbital sander?

Use a fine grit (180+) and ensure the sander has a random orbit. Work in overlapping passes and keep the sander flat. Avoid applying too much pressure.

Can I use a random orbital sander on metal?

Yes, with the correct sandpaper. Use aluminium oxide or zirconia discs for metal. The sander itself will handle it, but expect faster wear on the sandpaper.

What is the best grit for sanding wood before painting?

Start with 120 grit to remove imperfections, then finish with 180 or 220 grit for a smooth surface. Always sand in the direction of the grain for the final pass.

How long should a random orbital sander last?

A quality sander like the Bosch PEX 300 AE should last 5-10 years with regular DIY use. Budget models may last less, especially if used heavily. Proper maintenance helps.

Do I need a dust extractor for a random orbital sander?

Not necessarily. Many models come with a microfilter dust box that captures most dust. For heavy use, connecting to a vacuum is better, but the box is fine for DIY.

Can I change the pad on a random orbital sander?

Yes, most pads are replaceable. They are usually held on by a screw or adhesive. Check the manufacturer's instructions for your specific model before attempting replacement.

Our verdict

For the best all-round performance, the Bosch PEX 300 AE is the clear winner, offering superb dust extraction, variable speed, and proven reliability. If you are on a very tight budget and need raw power, the Draper 450W is a strong alternative for aggressive sanding tasks.
