# Best Orbital Sander 2026: 10 Models Ranked — and the Amp Figures That Don't Add Up Source: https://www.ranked10.co.uk/home/best-orbital-sanders Published: 2026-09-15 | Updated: 2026-09-16 | Prices checked on Amazon UK on 2026-09-15 Buying an orbital sander on its amperage figure is the quickest way to be misled. Bosch lists its 270 W PEX 300 AE with '270 Amps' and its 220 W PEX 220 A with '220 Amps'. At 230 V those motors draw about 1.2 A and 0.9 A, so the wattage has been copied into the wrong box — an error of roughly 230x. Where the number survives the arithmetic it is trustworthy: 3.26 A on the 750 W Bosch Professional, 1.17 A on the 280 W DEWALT at 240 V. Shop by watts and orbit diameter. Treat any amp figure that equals the wattage as decoration. We ranked ten of the best orbital sander models on Amazon on four things we could check from the listings themselves: wattage, pad and orbit size, corded or cordless, and whether the electrical figures agree with one another. Price and the size of the review sample settled the order where the numbers were close. ## The ranking ### 1. Bosch Professional GET 75-150 750 W Random Orbit Sander - Price: £385.56 | Amazon rating: 4.7 from 47 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/bosch-professional-get-75-150 - Buy on Amazon: https://www.amazon.co.uk/dp/B07R896RSK?tag=ranked10-21 It ranks first because its 3.26 A figure is exactly what 750 W at 230 V works out to, and it is the only orbital sander here with a 150 mm disc. The 750 W motor and the 3.26 A rating are the same number seen from two sides: 3.26 x 230 = 750. That is unusual on this list, where two Bosch models print their wattage in the amperage box. Bosch also claims up to 45% more material removal from the direct-driven pad, and the 150 mm disc covers more surface per pass than the 125 mm pads on the rest of the field. In practice this orbital sander is aimed at large flat panels — doors, worktops, tabletops. The palm rest and handle have an 18 cm gripping circumference, and the multi-hole pad accepts sheets with different hole patterns, which matters if you buy discs in bulk. Item weight is 3.15 kg and the manufacturer warranty is two years, against one year on the DEWALT. The catch is weight and price together. At 3.15 kg it is nearly twice the 1.7 kg Bosch PEX 300 AE and more than double the 1.63 kg DEWALT, so it is not a one-handed tool for overhead work or for reaching into a cabinet. At £385.56 it costs more than four times the DEWALT. If you sand a few shelves a year, this is not the tool you need. Pros: 3.26 A at 230 V backs up the 750 W badge exactly — the arithmetic agrees; 150 mm disc, the largest here; every other model uses 125 mm; Claims up to 45% higher removal rate from direct-driven pad rotation; 2-year manufacturer warranty, against 1 year on the DEWALT; 4.7 average from 47 ratings, 85% of them five-star Cons: 3.15 kg — the heaviest tool on this list by a wide margin; £385.56, roughly four times the price of the 280 W DEWALT; Only 47 ratings, a thin sample next to the 4,330 on the PEX 220 A; Corded only, with no battery option ### 2. DEWALT DWE6423-GB 280 W Random Orbit Sander, 125 mm - Price: £90.50 | Amazon rating: 4.5 from 651 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/dewalt-dwe6423-random-orbit-sander - Buy on Amazon: https://www.amazon.co.uk/dp/B01E3VFZ7E?tag=ranked10-21 Second because 1.17 A at 240 V lands within a watt of its 280 W badge, and 651 ratings make it the most tried corded model here. The listing says 280 W and 1.17 A at 240 V. Multiply and you get 280.8 W. This is a 125mm random orbit sander whose two electrical figures do not contradict each other, which cannot be said of the two Bosch PEX models further down this article. The practical case is the speed control. It is the only tool in the top ten with a verified variable range of 8,000 to 12,000 opm, so you can slow it for paint edges and open it up for bare timber. Dual-plane counter-balance and an overmoulded top grip are aimed at vibration, and the whole tool weighs 1.63 kg. The 125 mm hook-and-loop platen takes standard discs. However, two details are worth weighing. The warranty is one year, half the two years Bosch and DCA offer. And the spec table rates grit at '1' while the grit type reads 'Coarse' — the two fields on the same page disagree, which is the sort of thing this site exists to point out. If you only want to flatten a couple of boards, the 300 W DCA does it for a third of the price. Pros: 1.17 A at 240 V works out at 280.8 W, matching the 280 W badge; 651 ratings, the second-largest sample in this top ten; Variable speed from 8,000 to 12,000 opm; 125 mm hook-and-loop platen for quick disc changes; 1.63 kg, lighter than both corded Bosch models Cons: 1-year warranty, against 2 years on Bosch and DCA; Corded only, so a cable follows you round the work; Grit rating field says '1' while grit type says 'Coarse'; No orbit diameter published anywhere on the listing ### 3. Milwaukee M18 BOS125-0 18V Random Orbit Sander, Bare - Price: £89.59 | Amazon rating: 4.7 from 1,136 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/milwaukee-m18-bos125-0 - Buy on Amazon: https://www.amazon.co.uk/dp/B07GQ11768?tag=ranked10-21 Third on 1,136 ratings at 4.7 — the largest and highest-scoring sample here — with a 1.4 kg body and no amp figure to doubt. This is the random orbital sander with the strongest review base in the group: 1,136 ratings at 4.7, against 651 for the DEWALT and 142 for the DCA. Milwaukee does not inflate numbers here, and it does not publish many either. It is a bare unit. No battery, no charger, and no wattage or amperage anywhere on the listing, which means there is nothing to catch out and nothing to compare electrically with any corded model. What it does give you is 1.4 kg and the M18 platform, so a battery you already own may fit. Its best sellers rank of 20 in random-orbit sanders confirms steady demand rather than a novelty spike. That said, buy it only if you are already in the M18 system. A first-time buyer has to add a battery and charger to the £89.59 price, which quickly puts it past the corded DEWALT. The listed disc is 5 inches, which is 127 mm rounded down to 125 mm — fine, but check your discs match before ordering. Pros: 1,136 ratings at 4.7, the largest and highest-scoring sample here; 1.4 kg, light for an 18 V tool; Best sellers rank of 20 in random-orbit sanders; M18 platform means existing batteries and chargers fit; No inflated amp claim to decode Cons: Bare unit — battery and charger cost extra on top of £89.59; No wattage or amperage published, so no electrical comparison is possible; Bullet point says 1.41 kg, spec table says 1.4 kg; Disc described as 5 inches rather than the metric 125 mm ### 4. Einhell Professional 18V Brushless Random Orbital Sander, Bare - Price: £74.99 | Amazon rating: 4.7 from 641 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/einhell-cordless-orbital-sander-18v - Buy on Amazon: https://www.amazon.co.uk/dp/B0CV7R2YR8?tag=ranked10-21 Fourth because a brushless motor and 1.11 kg make it the lightest corded or cordless sander here, with a 3.2 mm orbit. This is the cordless orbital sander with the brushless motor, a 125 mm pad and a 3.2 mm orbit, and at 1.11 kg it is the lightest tool in the top ten. Weight matters more on a cordless tool than a corded one, because you are holding the whole sander plus a battery through every pass. In practice Einhell has built in dust collection — a collector with a pleated filter plus a port for an external extractor — and supplied three sheets in P60, P80 and P120 grit. Speed control is electronic, to adapt to the material at hand. The 18 V PXC battery system covers over 300 tools, which is the real argument for the platform rather than the sander itself. The catch is that it is a body-only sale. No battery, no charger, and no runtime figure published, so budget for both before comparing it with the £50.99 INGCO that includes them. The quoted 24,000 rpm is an orbit rate, not a disc rotation, and cannot be set against the DEWALT's 8,000 to 12,000 opm. Skip it if you do not already own PXC batteries. Pros: 1.11 kg — the lightest sander in this top ten; Brushless motor with electronic speed control; 125 mm pad and a 3.2 mm orbit; Dust collector, pleated filter and a port for an external extractor; One 18 V PXC battery fits over 300 Einhell tools Cons: Body only — battery and charger sold separately; No runtime figure published for any pack size; 24,000 rpm is an orbit rate and is not comparable with opm ratings elsewhere; Spare part availability listed at 1 year, the shortest in this article ### 5. Bosch PEX 300 AE 270 W Random Orbit Sander, 125 mm - Price: £79.56 | Amazon rating: 4.4 from 1,193 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/bosch-pex-300-ae - Buy on Amazon: https://www.amazon.co.uk/dp/B005GIU33U?tag=ranked10-21 Fifth because 1,193 ratings support a 270 W motor that genuinely draws about 1.17 A — and the page still prints '270 Amps'. 270 W at 230 V is 1.17 A. The listing instead says '270 Amps', which at 230 V would be 62,100 W. The wattage has been typed into the amperage box, an error of about 230x. The motor itself is fine; the number printed beside it is not. What you actually get is a 1.7 kg palm sander with a 125 mm disc, variable speed with the dial placed under the palm, and two pad hardnesses — medium-hard and soft — for flat and curved work. The dust box is integrated, so no extractor is needed for light jobs. Average rating is 4.4 from 1,193 ratings, the second-largest sample in the group. However, 4.4 is the joint-lowest score in this top ten, level with the £35.91 SORAKO, and only 67% of its ratings are five-star against 85% for the top pick. It is also 0.41 kg heavier than the 220 W PEX 220 A. If you want a Bosch at a lower price, the smaller one is the better buy; if you want more power, this is not the step up. Pros: 270 W motor, which is about 1.17 A at 230 V; 1,193 ratings, the second-largest sample in the group; Two pad hardnesses, medium-hard and soft; Variable speed dial placed under the palm; Integrated dust box, no separate extractor needed for light work Cons: Listed at '270 Amps' — the wattage in the wrong field, a 230x error; 4.4 average, level with the cheapest sander here; 1.7 kg, heavier than the 1.29 kg PEX 220 A; Only 67% of ratings are five-star, against 85% for the top pick ### 6. RYOBI 18V ONE+ 125 mm Random Orbit Sander, Bare - Price: £67.30 | Amazon rating: 4.7 from 834 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/ryobi-18v-random-orbit-sander - Buy on Amazon: https://www.amazon.co.uk/dp/B09VTG7H5G?tag=ranked10-21 Sixth because 834 ratings at 4.7 back a 2.5 mm orbit, the largest here, but its '5 Amps' cannot be checked against anything. Five amps at 18 V is 90 W. No wattage appears anywhere on the listing, so that figure stands alone and cannot be confirmed or contradicted. By contrast, every corded model here pairs an amp figure with a watt figure, which is why this one sits sixth rather than higher. On paper the rest is sensible. The 2.5 mm orbital motion is the largest orbit in this top ten, which suits fast stock removal rather than fine finishing. It weighs 1.2 kg and ships with three sheets in 80, 120 and 240 grit plus a dust bag. Spare parts are listed as available for five years, the longest commitment in the group. That said, it is a bare tool: no battery, no charger, no runtime. Worth noting too that the 20,000 rpm in the spec table is an orbit speed, so do not read it as disc rotation, and the grit rating field says 240.0 while the grit type says 'Medium'. If you are not already on the ONE+ platform, the corded DCA at £32.99 is a third of the money. Pros: 2.5 mm orbit, the largest in this top ten, for fast stock removal; 834 ratings at 4.7; 5-year spare part availability, the longest here; 1.2 kg, light for an 18 V tool; Three sheets supplied: 80, 120 and 240 grit Cons: Bare tool — battery and charger not included; Listed at 5 A with no wattage to check it against; No runtime quoted for any battery; Grit rating field reads 240.0 while grit type reads 'Medium' ### 7. Bosch PEX 220 A 220 W Random Orbit Sander, 125 mm - Price: £51.99 | Amazon rating: 4.5 from 4,330 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/bosch-pex-220-a - Buy on Amazon: https://www.amazon.co.uk/dp/B0002KHIN0?tag=ranked10-21 Seventh despite '220 Amps' on the page, because 4,330 ratings make it the most-reviewed orbital sander here and £51.99 is the second-lowest price. The same copy-paste fault appears on the cheaper Bosch: 220 W at 240 V is about 0.92 A, but the amperage box says '220 Amps', which would be 52,800 W. Even so, 4,330 people have rated it and 4.5 is a solid average on a sample that size — roughly 92 times the 47 ratings behind the top pick. The tool is a 1.29 kg palm sander with a 125 mm disc, a microfilter dust box and a rubber sanding pad, sold with three sheets in a carton. Its best sellers rank of 7 in random-orbit sanders is the highest position in this article, so it sells on price and familiarity as much as on specification. Meanwhile the limit is output: 220 W against 300 W from the DCA and 350 W from the SORAKO, both corded and both cheaper. The voltage field also reads 240 V where Bosch's other models read 230 V. Buy this for flat or curved panels and light finishing; do not buy it if you are stripping paint in bulk. Pros: 4,330 ratings at 4.5, the largest review sample in this article; £51.99, the second-lowest price here; 1.29 kg and a palm grip for one-handed work; Microfilter dust box included; Best sellers rank of 7 in random-orbit sanders Cons: Amperage field says '220 Amps' against a 220 W motor — a 240x error; 220 W, the weakest corded motor in the top ten; Voltage listed as 240 V while other Bosch models list 230 V; Grit type reads 'Coarse, Fine' and grit rating reads 60 — the fields overlap ### 8. DCA 300 W Random Orbital Sander, 125 mm, 10 Sheets - Price: £32.99 | Amazon rating: 4.7 from 142 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/dca-300w-random-orbital-sander - Buy on Amazon: https://www.amazon.co.uk/dp/B0FCRM7S2T?tag=ranked10-21 Eighth: a 300 W motor, six speeds and ten sheets for £32.99, but the listed 3 Amps would mean 690 W at 230 V. This is the cheapest corded tool here at £32.99, and the one to look at if you want an orbital sander for wood without spending £90. The motor is rated at 300 W with six speeds from 4,000 to 12,000 opm, and the box includes ten sheets across five grits. In practice the electrical figures do not hold together. Three amps at 230 V is 690 W, which is more than twice the 300 W badge on the same page. The error runs the opposite way to Bosch's: here the amp figure overstates the tool rather than understating it, and either way the amp box is the one to ignore. The rest of the package is straightforward — a 0.3 litre dust bag, hook-and-loop sheets, 1.31 kg, and a 2-year manufacturer warranty. Crucially, 142 ratings is the second-smallest sample in this article, so treat the 4.7 average with more caution than the DEWALT's 4.5 from 651. It is a good first sander and a poor last one: if you sand often or need a large pad, the 125 mm platen is the same as almost every rival and will not help you. Pros: £32.99 — the lowest price among the corded sanders here; 6 speeds from 4,000 to 12,000 opm; Ten sanding sheets supplied, 80 to 320 grit; 2-year manufacturer warranty; 1.31 kg with a 0.3 litre dust bag Cons: Listed at 3 Amps; at 230 V that is 690 W, more than double the 300 W badge; 142 ratings, a small sample; 0.3 litre dust bag fills quickly on long jobs; Grit rating field reads 240 while grit type reads 'Medium, Fine, Extra Fine' ### 9. SORAKO 350 W Random Orbital Sander, 125 mm, 16 Sheets - Price: £35.91 | Amazon rating: 4.4 from 186 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/sorako-350w-random-orbital-sander - Buy on Amazon: https://www.amazon.co.uk/dp/B0DM8ZN59Y?tag=ranked10-21 Ninth: the highest wattage under £40 and 16 sheets in the box, held back by the largest share of one-star ratings here. 350 W is the most power you can buy here for under £40, and the box carries 16 sheets in four grits. Against the DCA's 300 W and ten sheets, the SORAKO wins on both counts, for £2.92 more. Even so, it sits below the DCA on this list. The reason is the pattern of the ratings. Seven per cent of the ratings shown are one-star, the highest share in this top ten, and 76% are five-star against 79% for the DCA. The features are otherwise comparable: six speeds to 13,000 rpm, a soft rubber wrap, an eight-hole dust pad, a dust bag and a 32 mm extraction adapter. Note the small print in the description: the maker states it is not for grinding walls or lime. At 1.62 kg it is also the second-heaviest tool in this article, and heavier than the 220 W Bosch that undercuts it on price. For furniture repair and occasional stripping it is a fair punt; for a tool you expect to still be using in five years, look higher up. Pros: 350 W, the most power under £40 here; 16 sanding sheets supplied, 80 to 240 grit; 6 speeds up to 13,000 rpm; Dust bag plus a 32 mm dust collection adapter; £35.91, only £2.92 more than the 300 W DCA Cons: 7% of the ratings shown are one-star, the highest share in this top ten; 1.62 kg, the second-heaviest tool here; The description states it is not for grinding walls or lime; 76% five-star, below the 79% of the DCA ### 10. INGCO 20V Brushless Cordless Random Orbit Sander, 125 mm - Price: £50.99 | Amazon rating: 4.6 from 85 ratings - Full review: https://www.ranked10.co.uk/home/best-orbital-sanders/ingco-20v-random-orbit-sander - Buy on Amazon: https://www.amazon.co.uk/dp/B0DPHWDKPL?tag=ranked10-21 Tenth: at 800 g it is the lightest tool here and the only cordless one that arrives with a battery and charger, but 85 ratings is the smallest sample. This is the only cordless model in the top ten that includes a battery and a charger in the £50.99 price. The Einhell, Milwaukee and RYOBI are all body-only, so the like-for-like cost of those three is higher than their headline figures suggest. It also weighs 800 g, the lightest tool in this article by 310 g. The brushless motor runs 8,000 to 13,000 rpm through six speeds, driving a 125 mm pad, with a dust collection design built in and five sheets in the box. The 2.0 Ah battery belongs to the 20V P20S platform, so it fits other INGCO tools you may already own. The catch is the evidence. Eighty-five ratings is the thinnest sample here, roughly a thirteenth of the DEWALT's 651, and no runtime is quoted for the 2.0 Ah pack. At the same time, 8,000 to 13,000 rpm is a narrower band than the DCA offers for £18 less. Buy it for small jobs and low weight; do not buy it as your only sander. Pros: 800 g — the lightest tool in this top ten; Battery, charger and five sheets included at £50.99; Brushless motor with six speeds, 8,000 to 13,000 rpm; 2.0 Ah pack fits the wider INGCO 20V P20S platform; 125 mm pad with built-in dust collection Cons: 85 ratings, the smallest sample here; No runtime published for the 2.0 Ah battery; Six speeds spanning 5,000 rpm, a narrower band than the £32.99 DCA; Spare part availability not stated on the listing ## Verdict For most homes the 280 W DEWALT at £90.50 is the safest orbital sander to buy: 651 ratings, a 1.17 A draw that matches its 280 W badge at 240 V, and variable speed from 8,000 to 12,000 opm. If you want a cheap orbital sander for occasional work, the 300 W DCA at £32.99 includes ten sanding sheets and a 2-year warranty — though its 3 A claim would mean 690 W at 230 V. And if you sand large flat panels and can spend £385.56, the 750 W Bosch Professional has the only 150 mm disc here and an amp figure that agrees with its wattage.
