Bosch GEX 125-150 AVE
Best OverallPros
- Outstanding dust extraction with microfilter system
- Very low vibration for fatigue-free use
- Constant electronic speed control under load
Cons
- Hook and loop pad can wear over time
- Not the most powerful motor for heavy stock removal
The Bosch GEX 125-150 AVE is widely regarded as the best random orbital sander in its price range, primarily due to its advanced dust management. The integrated microfilter system captures fine dust directly at the source, keeping your workspace cleaner than most competitors. Owner reviews consistently highlight the effectiveness of the dust collection, even when sanding softer woods.
Performance is smooth and controlled, with a variable speed dial that allows precise adjustment from 12,000 to 22,000 orbits per minute. The 250 W motor is adequate for finishing and light stock removal. The soft-grip handle and low vibration levels make it comfortable for extended sanding sessions.
Makita BO5041
Best ValuePros
- Very affordable price point
- Larger 2.8 mm orbit for faster material removal
- Durable Makita build quality
Cons
- Dust extraction is not as effective as the Bosch
- Lower maximum speed compared to competitors
The Makita BO5041 is a solid, no-frills random orbital sander that offers excellent value for money. It features a larger 2.8 mm orbit, which allows it to remove material faster than many finer-orbit sanders. This makes it a good choice for DIYers who need to strip paint or smooth rough surfaces quickly.
Owner reviews praise its reliability and comfortable grip, though some note that the dust collection through the pad could be better. The 200 W motor is sufficient for most tasks, but the lower max speed of 12,000 opm means it is less suited for ultra-fine finishing work compared to the Bosch.
DeWalt DWE6423
Best for Aggressive SandingPros
- Powerful 300 W motor for heavy stock removal
- Dust-sealed switch for longer life
- Comfortable rubber overmold grip
Cons
- Heavier than many competitors
- Dust bag is small and needs frequent emptying
The DeWalt DWE6423 is built for power. With a 300 W motor, it is the most powerful sander on this list, making it ideal for aggressive sanding tasks like removing thick paint or leveling uneven wood. The 2.4 mm orbit provides a good balance between material removal and a fine finish.
User feedback highlights its robust construction and the effective dust-sealed switch, which prevents debris from entering the tool. However, the included dust bag is on the smaller side, and the tool is noticeably heavier at 1.6 kg, which may cause fatigue during long sessions.
Ryobi R18ROS-0
Best CordlessPros
- Full cordless freedom for remote work
- Compatible with the extensive Ryobi One+ battery system
- Variable speed trigger for easy control
Cons
- Battery and charger sold separately
- Smaller 2.0 mm orbit is less effective for heavy stock removal
The Ryobi R18ROS-0 is the best cordless option for users who already own Ryobi tools. It offers the convenience of no cord, making it perfect for sanding in tight spaces or working outdoors. The variable speed trigger gives you good control over the sanding speed, from 10,000 to 22,000 opm.
Owner reviews note that battery life is decent for finishing tasks, but the smaller 2.0 mm orbit means it is not ideal for aggressive material removal. The tool is lightweight and well-balanced, though the lack of a dust bag in the box is a minor inconvenience for some users.
Einhell TC-RO 1155 E
Best Entry LevelPros
- Very low price, ideal for beginners
- Large 3.0 mm orbit for fast material removal
- Lightweight and easy to handle
Cons
- Lower power motor struggles with hardwoods
- Dust collection is basic and not very effective
The Einhell TC-RO 1155 E is an entry-level sander designed for occasional DIY use. Its large 3.0 mm orbit allows for quick material removal on softwoods and painted surfaces. The 150 W motor is sufficient for light tasks, but it will bog down under heavy pressure on harder materials.
Owner reviews appreciate the value for money but note that the dust extraction is poor and the build quality feels less robust than premium brands. It is best suited for hobbyists who need a cheap tool for small projects and are not concerned with fine finishing.
What to check before buying a random orbital sander
Before making a purchase, consider the motor power. A higher wattage (over 250 W) is better for heavy stock removal, while lower power (around 150-200 W) is fine for finishing. The orbit diameter also matters: a 2.5 mm orbit offers a good balance, while a 3.0 mm orbit removes material faster but leaves a slightly coarser finish.
Dust extraction is critical for a clean workspace. Look for models with a microfilter system or a dust port that can connect to a vacuum. Also, check the ergonomics: a lightweight sander with a soft-grip handle reduces fatigue during extended use.
Mistakes to avoid when buying a random orbital sander
Do not choose a sander solely based on price. A very cheap model may have poor dust extraction and a weak motor that struggles with hardwoods. Avoid ignoring the orbit size: a small orbit (under 2.0 mm) is slow for material removal, while a large orbit (over 3.0 mm) may leave swirl marks.
Do not forget to check the pad size. Most sanders use 125 mm or 150 mm pads, and you need to ensure replacement discs are readily available. Also, avoid buying a cordless sander if you do not already own batteries from that brand, as the cost of a battery and charger can push the total price over budget.
FAQs
What is the best random orbital sander under £150?
The Bosch GEX 125-150 AVE is the best overall due to its excellent dust extraction and smooth variable speed control.
Is a cordless random orbital sander as good as a corded one?
Cordless sanders offer convenience but often have less power and shorter run times. For heavy use, a corded model is usually more reliable.
What orbit size is best for a random orbital sander?
A 2.5 mm orbit is a good all-rounder for both material removal and finishing. A 3.0 mm orbit is faster for stripping, while a 2.0 mm orbit is better for fine sanding.
Do I need a sander with variable speed?
Yes, variable speed allows you to adjust the sander for different materials. Lower speeds are better for plastics and paint, while higher speeds are for wood.
How important is dust extraction on a sander?
Very important. Good dust extraction keeps your workspace clean and extends the life of your sandpaper. Look for models with a microfilter or a vacuum port.
Can I use a random orbital sander for wet sanding?
No, random orbital sanders are not designed for wet sanding. Using them with water can damage the motor and create a safety hazard.
What is the difference between a random orbital sander and a finishing sander?
A random orbital sander moves in a random pattern to avoid swirl marks, making it better for fine finishes. A finishing sander moves in a fixed orbit and is less versatile.
How long should a random orbital sander last?
With proper maintenance, a quality sander from Bosch or Makita can last 5-10 years. Cheaper models may have a shorter lifespan.
Can I use a random orbital sander to remove paint?
Yes, but you will need a coarse grit sandpaper (40-60 grit) and a sander with a powerful motor. The DeWalt DWE6423 is a good choice for this task.
What safety gear should I use when sanding?
Always wear a dust mask or respirator, safety glasses, and hearing protection. Sanding produces fine dust that can be harmful if inhaled.
Our verdict
For most users, the Bosch GEX 125-150 AVE is the best random orbital sander under £150, offering superior dust extraction and smooth operation. If you are on a budget, the Makita BO5041 provides excellent value and reliable performance for general sanding tasks.
