A low-vibration DEWALT sander with strong value at its lowest price

Yes — the DEWALT DWE6423-GB 240V 125mm eccentric sander is worth buying if you want a mains-powered random-orbit sander with proper control, good dust handling, and a proven user rating of 4.6/5 from 625 reviews. At £104.32, it is currently at its all-time lowest price, which makes it far easier to justify than when bought at full RRP (£114.00).

First impressions

This is a straightforward, workmanlike DEWALT sander rather than a flashy one. The spec sheet tells you exactly what it is built for: a 280W motor, 8,000–12,000 opm, a 125mm hook-and-loop platen, and a variable speed dial. That combination suits fine finishing on softwood, hardwood, and painted surfaces where you want to avoid swirl marks and keep the pad moving cleanly across the grain.

The design details matter here. The dual plane counter-balance is there to reduce vibration, and that is one of the biggest differences between a decent sander and one that leaves your hands buzzing after half an hour. The overmould top and body grip should also help when you are working on cabinet parts, doors, or long sanding sessions on site or in a garage workshop.

How does it perform in use?

On paper, the 8,000–12,000 opm range gives enough flexibility to back off for delicate finishing or wind it up for faster stock removal. For a random-orbit sander, that is the right kind of spread: you are not using it to flatten rough-sawn timber in one pass, but to refine surfaces after planing, remove old finish, and prepare wood for oil, varnish, or paint.

The 125mm hook-and-loop platen is a practical size because discs are widely available and quick to swap. That is useful in a real workshop where you may move between 80-grit for initial clean-up, 120-grit for levelling, and finer grades for finishing. The hook-and-loop system should also keep discs seated securely, which helps reduce wasted paper and inconsistent sanding.

Dust control is another important point. The listing says it has direct compatibility with the AirLock system for secure connection to DEWALT dust extractors, with high dust-extraction efficiency. In practice, that matters because orbital sanding creates a lot of fine dust, especially on MDF, pine, and hardwoods like oak. Better extraction means less clogging, less airborne dust, and a cleaner finish.

Is the build quality good?

The features suggest a tool aimed at durability rather than gimmicks. A dust-sealed on/off switch is a sensible inclusion, because sanding dust is abrasive and can kill switches over time. DEWALT’s overmould grip and counter-balanced layout also point to a tool designed for regular use rather than occasional DIY.

That said, this is still a corded 240V machine, so it is not as convenient as a cordless sander for quick jobs or outdoor work away from power. You will need a lead, a socket, and ideally dust extraction to get the best from it. If you already run a mains workshop setup, that is not a drawback; if you want grab-and-go portability, it is.

Is it good value for money?

At £104.32, this DEWALT sits in a sensible middle ground. It is cheaper than the Bosch Rout POF 1400 ACE spindle lock at £238.99, though that is a different tool type, and pricier than the Makita DBO180Z at £79.99, which is a cordless sander with batteries and charger not included. The DEWALT’s value comes from the combination of corded power, low-vibration design, variable speed, and dust-extractor compatibility, not from being the cheapest option.

The key price point is that £104.32 is the all-time lowest recorded price, and the current price is 0.0% above average because the average is also £104.32. That means you are not paying a premium to buy now.

What should buyers watch out for?

The main limitation is simple: this is a single-option product with 1 variation available, so there is little flexibility on configuration. The other warning is that the listing data only shows 100+ bought last month and a sales rank of #7592 in category, which suggests it is not a mass-volume bestseller despite the strong rating.

Also, because it is a random-orbit sander, expectations need to be realistic. It is for finishing, levelling, and paint prep — not for aggressive timber removal or replacing a planer. Push too hard and you will still risk swirls or uneven results, especially on softer woods.

How does it compare to alternatives?

Against the Makita DBO180Z at £79.99, the DEWALT costs more, but you are comparing a corded 240V sander with a cordless unit that needs batteries and a charger separately. If you already own Makita 18V kit, the Makita may make more sense for portability. If you want consistent power and workshop use, the DEWALT is the stronger buy.

Compared with the Bosch Rout POF 1400 ACE at £238.99, the DEWALT is far cheaper, but again that Bosch is not the same machine category. The more relevant point is that DEWALT is offering a well-rated, dust-conscious finishing sander at a price that sits comfortably below premium tool territory.

Final assessment

This is a practical, well-specified sander with a strong review score, sensible ergonomics, and a price that is currently as low as it has ever been. If you do regular woodworking, furniture prep, or decorating work and already have a mains setup, the DWE6423-GB makes a lot of sense. If you need cordless portability or the absolute cheapest route into sanding, look elsewhere.
