# Best Cordless Drill 2026: 10 Ranked, and Why That 21V Is Really an 18V Source: https://www.ranked10.co.uk/home/best-cordless-drill Published: 2026-09-06 | Updated: 2026-09-12 | Prices checked on Amazon UK The biggest number on a cheap cordless drill is usually a fib. That "21V" or "20V" on the box is not the working voltage — it is the voltage of the battery for a split second, freshly charged and with nothing connected. A standard drill battery has five lithium-ion cells in series; each reads about 4.2 volts brimming (5 x 4.2 = 21) but settles to 3.6 volts in normal use (5 x 3.6 = 18). So a "21V" drill and an honest "18V" drill have the same battery. This is exactly why Bosch, Makita, DeWalt and Ryobi all label theirs 18V: it is the truthful, under-load figure. When a budget brand shouts 20V or 21V, it is quoting the flattering no-load number the others leave off. The torque figure deserves the same suspicion — "maximum torque" in newton metres has no single agreed test, so a drill can claim 45Nm and deliver far less against a real screw, and some listings even print the unit wrong. So we ranked ten of the best cordless drill options on Amazon in September 2026 on the things that actually decide the job — the battery's real capacity in amp-hours, whether the motor is brushless, honest torque and speed, whether a battery and charger are in the box, and how much proven evidence sits behind each — rather than the voltage on the label. ## The ranking ### 1. RYOBI 18V ONE+ Cordless Combi Drill Starter Kit with Battery and Charger - Price: £66.96 | Amazon rating: 4.7 from 7,188 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B07YT5HGH3?tag=ranked10-21 The safe home pick: an honest 18V, a complete kit and one of the deepest review pools anywhere, feeding a huge battery family. This is the cordless drill most homes should buy, and the reasons are the boring, important ones. It is an honest 18V combi drill — Ryobi does not dress it up as 20V — supplied as a complete starter kit with a battery, charger and bag, so you are drilling the moment it arrives. With more than seven thousand ratings at 4.7 stars, it is also one of the most proven tools on this page. The real argument for it is the ONE+ system. The same battery fits over three hundred Ryobi tools, from sanders to strimmers to inflators, so this drill is a doorway rather than a dead end. As a combi it adds a hammer setting for the occasional wall plug in masonry, and a two-speed gearbox for driving screws slowly and drilling quickly. For everyday DIY it has all the muscle you need without paying for professional overkill. It uses a brushed motor rather than brushless, so it is a touch less efficient than the Makita below, and the supplied battery is a starter capacity — fine for jobs around the house, but heavy users will want a second, larger pack. As a first drill that grows with you, though, nothing here beats it. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Honest 18V, sold as a full kit with battery and charger; ONE+ battery fits 300+ Ryobi tools — a real ecosystem; Combi with a hammer setting and two-speed gearbox; Hugely proven: 7,188 ratings at 4.7; Great value for a complete starter package Cons: Brushed motor, not brushless; Supplied battery is a starter capacity; Heavy users will want a second, larger battery ### 2. Makita DHP484Z 18V LXT Brushless Combi Drill (Body Only) - Price: £88.00 | Amazon rating: 4.7 from 2,472 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B01LYXFYLB?tag=ranked10-21 The step up in muscle: a brushless 18V pro-grade combi with the highest torque here — but supplied body only. If you want more power than a DIY drill, the DHP484Z is the pick. It is a professional-grade 18V LXT combi with a brushless motor, which squeezes more torque and more runtime from the same battery and lasts longer because there are no brushes to wear out. Its 54 newton-metre maximum is the highest on this page, and at 4.7 stars over 2,472 ratings it is deeply trusted by tradespeople and serious DIYers alike. Because it is brushless it stays cooler and more efficient under load, so it will drive big screws and bore larger holes without bogging down the way a budget drill does. The two-speed gearbox and hammer action cover everything from delicate driving to masonry, and the build quality is a clear step above the sub-£40 machines lower down. The catch is that it is sold body only — no battery or charger — so unless you already own Makita LXT batteries, the real cost is higher than the sticker. It is honest about being 18V, which is the point of this ranking, and if you are buying into the Makita system it is superb. First-time buyers who need a battery too should weigh the Ryobi kit above. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Brushless motor: more power, more runtime, longer life; Highest torque here at 54Nm; Honest 18V LXT, pro-grade build; Two-speed gearbox and hammer action; Deeply proven: 2,472 ratings at 4.7 Cons: Body only — no battery or charger included; Real cost is higher once you add an LXT battery; Overkill for occasional light jobs ### 3. Bosch Cordless Combi Drill EasyImpact 18V-40 (2 Batteries 2.0 Ah, Charger, Case) - Price: £80.00 | Amazon rating: 4.6 from 503 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0C1H4DNMN?tag=ranked10-21 The complete DIY package: honest 18V with two batteries, a charger and a case, from Bosch's home range. The EasyImpact 18V-40 is the drill to buy if you want everything in the box and no surprises. It is an honest 18V combi from Bosch's green home line, and it ships with two 2.0Ah batteries, a charger and a carry case — so one battery charges while the other works, and you never stop mid-job. At 4.6 stars it is well reviewed, and Bosch's green batteries power a wide range of home and garden tools. With a 40 newton-metre maximum and a 1,630 rpm top speed it has plenty for shelves, flat-pack, curtain poles and the odd masonry plug via its impact setting. The two-battery kit is the standout: many rivals at this price give you one small pack or none at all, so having a spare included is genuine everyday value. It is a brushed motor rather than brushless, so it is a little less efficient than the Makita, and its torque sits below the pro machines. But as a no-fuss, fully-equipped home drill from a trusted name, it is hard to fault. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Honest 18V, with two 2.0Ah batteries plus charger and case; A spare battery included — rare at this price; Impact setting for occasional masonry; Trusted Bosch green home ecosystem; 4.6 stars across 503 ratings Cons: Brushed motor, not brushless; Torque below the pro-grade options; Fewer reviews than the Ryobi or Makita ### 4. DEWALT 18V XR Li-Ion Cordless Combi Hammer Drill DCD776 (Body Only) - Price: £58.50 | Amazon rating: 4.6 from 415 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B00T7UCIYA?tag=ranked10-21 The cheapest way into DeWalt's 18V XR system: an honest, capable combi hammer drill — body only. The DCD776 is the affordable entry point to DeWalt's respected 18V XR platform. It is an honest 18V combi hammer drill with a 13mm chuck, a two-speed gearbox and a 42 newton-metre maximum, and it carries the build reputation that makes DeWalt a fixture on building sites. At 4.6 stars it is well liked, and buying into XR means access to a large family of professional tools on the same battery. As a combi it drills, drives and hammers into masonry, covering the full range of household jobs, and the yellow-and-black build shrugs off the knocks that kill cheaper drills. For someone who wants a tool that will last a decade rather than a season, it is a sound choice. Like the Makita, it is sold body only, so factor in an XR battery and charger if you do not already have them — that pushes the true cost up. It is genuinely 18V, not a dressed-up 20V, and that honesty is exactly what this ranking rewards. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Honest 18V XR, into a pro tool ecosystem; Combi hammer with 13mm chuck and two speeds; Tough, site-proven DeWalt build; Cheapest route into the XR platform; 4.6 stars across 415 ratings Cons: Body only — no battery or charger; True cost higher once you add an XR battery; Brushed motor, not brushless ### 5. Terratek 18V Cordless Drill Set Driver with Battery and 13-Piece Kit - Price: £24.99 | Amazon rating: 4.3 from 16,141 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B00I506718?tag=ranked10-21 The honest budget champion: cheap, hugely reviewed and truthfully labelled 18V — but genuinely light-duty. The Terratek is the budget drill that does not lie to you, and that alone earns its place. It is labelled a truthful 18V, not a flattering 20V, costs under twenty-five pounds, and comes with a battery and a 13-piece accessory kit. With more than sixteen thousand ratings it is the most reviewed tool on this entire page — a genuine best-seller for casual jobs. What you must be clear-eyed about is that it is light-duty. Its 18 newton-metre torque, 650 rpm top speed and small 1.3Ah battery are modest, so it is built for hanging pictures, assembling flat-pack and light screwdriving rather than drilling masonry or driving long coach screws. For that gentle use it is excellent value, and its enormous review count shows how many people it keeps happy. Ask more of it and it will struggle — this is not the drill for a decking project. But as an honest, cheap, do-the-basics tool, it is the best sub-£25 option here, and a refreshing contrast to the inflated-voltage machines below it that cost more and claim more. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Truthfully labelled 18V, not a dressed-up 20V; Under £25 with a battery and 13-piece kit; The most reviewed tool here: 16,141 ratings; Ideal for flat-pack, shelves and light screwdriving Cons: Light-duty: only 18Nm and 650 RPM; Small 1.3Ah battery, short runtime; Not for masonry or heavy driving; No brand tool ecosystem to grow into ### 6. DCA 20V Brushless Cordless Hammer Drill Set, 55Nm, with Accessory Kit - Price: £53.54 | Amazon rating: 4.3 from 79 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0FCXPTJL9?tag=ranked10-21 A lot of kit for the money and a real brushless motor — but the voltage is the usual 18V-in-disguise, and the spec sheet slips. The DCA is the best of the inflated-voltage drills, because underneath the marketing it has a genuinely useful feature: a brushless motor, which is rare at this price and gives better efficiency and life than the brushed budget machines. It arrives as a big set with batteries, a hammer function, a flexible shaft and a 19-piece bit kit, so it looks like tremendous value at around fifty pounds. But the label is the familiar trick. It is sold as "20V", which its own specification quietly qualifies as "20 Volts (DC)" — the no-load figure of what is, in working terms, an 18V pack. The torque claim wobbles too: the listing gives a 55Nm maximum but then records the figure as "55 Newton Millimetres", a unit a thousand times smaller and plainly a catalogue slip. Read the voltage as 18V and treat the torque as optimistic and you know what you are getting. The bigger caveat is evidence: at 79 ratings it is far less proven than the established brands above, so there is little long-term track record for the motor or batteries. We do not mark it down for being new — the brushless motor and generous kit are real — but at this price the risk is yours to weigh. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Genuinely brushless — rare at this price; Big set: batteries, hammer, flexible shaft, 19-piece bits; Around £50 for a lot of tool and accessories; Hammer function for masonry Cons: "20V" is the no-load figure of an 18V pack; Spec lists torque as "55 Newton Millimetres" — a catalogue error; Only 79 ratings — thinly proven; No established tool ecosystem ### 7. FADAKWALT 20V Cordless Drill with 2 Batteries, Charger and Case - Price: £37.99 | Amazon rating: 4.4 from 997 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0F8HTD2P2?tag=ranked10-21 A well-reviewed budget kit with two batteries — but the 20V is an 18V in disguise and the torque claim contradicts itself. The FADAKWALT is a popular budget kit that gets the basics right: two batteries so you can keep working, a charger, a case and a set of bits, all for under forty pounds. With nearly a thousand ratings at 4.4 stars it is the most proven of the sub-£40 drills here, and for light home use readers clearly get on with it. The numbers, though, follow the pattern this ranking exists to expose. It is sold as "20V", which the specification lists plainly as 20 volts — the flattering no-load reading of a standard 18V battery. And the torque claim contradicts itself on the same page: the headline maximum is 35Nm, but the specification's own torque field says 21Nm. The lower figure is the more honest one to plan around, and it marks this out as a light-duty tool. With 1,500 rpm and small 1.5Ah batteries it will handle flat-pack, shelves and light screwdriving happily, but it is not built for masonry or heavy work. As an honest-value package for gentle jobs — provided you read "20V" as 18V and "35Nm" as nearer 21 — it is a reasonable buy. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Two batteries, charger, case and bits under £40; Best-reviewed sub-£40 drill here: 997 ratings; Fine for flat-pack and light screwdriving; Spare battery keeps you working Cons: "20V" is the no-load figure of an 18V pack; Torque claim contradicts itself: 35Nm headline vs 21Nm in the spec; Small 1.5Ah batteries; light-duty only; Brushed motor; no tool ecosystem ### 8. DYJPOW 21V Brushless Cordless Drill Driver with 2 x 2.0Ah Batteries - Price: £38.39 | Amazon rating: 4.7 from 15 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0H8RN7GR2?tag=ranked10-21 Brushless and cheap with two batteries — but the 21V is the clearest 18V-in-disguise here, and the reviews are still very few. The DYJPOW pairs two things that rarely meet at this price: a brushless motor and two 2.0Ah batteries, for under forty pounds. On paper that is a strong budget package — brushless efficiency plus a spare pack — and its early reviewers rate it 4.7 stars. The headline, though, is the purest example of this ranking's point. "21V" is precisely the number you get by reading a fully-charged 18V battery with nothing plugged in: five cells at 4.2 volts. Under load it is an 18V drill like the honest ones above, just labelled with the flattering figure. Its 45Nm torque claim is respectable for the class, though, as ever, unstandardised. The real hesitation is evidence: with just 15 ratings there is almost no track record, so the brushless motor and batteries are unproven over time. In keeping with our approach we do not reject it for being new — the specification is genuinely good for the money — but a 4.7 average on 15 reviews is far less reassuring than the thousands behind the drills at the top. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Brushless motor and two 2.0Ah batteries under £40; Decent 45Nm torque claim for the class; Spare battery included; Strong early rating Cons: "21V" is exactly an 18V pack read unloaded; Only 15 ratings — almost no track record; A high average on a tiny sample is unreliable; No established tool ecosystem ### 9. 20V Cordless Drill Set with 40Nm Torque, 2 Batteries and Two-Speed - Price: £39.99 | Amazon rating: 4.2 from 31 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0GF646QP7?tag=ranked10-21 A generic budget kit whose spec sheet is a catalogue of the usual tells: 18V-in-disguise voltage and a nonsense amperage field. This unbranded 20V set is a typical budget offering: a two-speed drill with a 40Nm torque claim, batteries and a bit kit for around forty pounds. For occasional, light household jobs it will drive screws and drill pilot holes, and its 4.2-star average across 31 ratings suggests casual users are broadly satisfied. The specification, though, reads like a checklist of the things this ranking warns about. The "20V" is the no-load reading of an 18V pack. The amperage field says "16 Amps", a figure that means nothing sensible for a drill of this kind and looks like a mis-filled catalogue box. And the battery is a small 1.5Ah, so runtime is limited. Translate the voltage to 18V, ignore the stray amperage, and you have a modest light-duty drill. The evidence is thin at 31 ratings, so there is little to go on for reliability, and there is no brand ecosystem behind it. It is not a bad tool for gentle use, but for a similar price the honest, hugely-reviewed Terratek or the two-battery FADAKWALT are easier to trust. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Two-speed gearbox and two batteries; Around £40 with a bit kit; Adequate for light, occasional jobs; 40Nm claim is reasonable for the class Cons: "20V" is an 18V pack read unloaded; Spec lists a meaningless "16 Amps" amperage; Small 1.5Ah battery; limited runtime; Only 31 ratings and no ecosystem ### 10. Cordless Drill 21V with 18-Position Torque, 2 Batteries, 45Nm Max - Price: £24.99 | Amazon rating: 4.6 from 3 ratings - Buy on Amazon: https://www.amazon.co.uk/dp/B0GRG5WZV3?tag=ranked10-21 The cheapest and least proven here — the purest 21V-that-is-really-18V, closing the ranking on trust, not evidence. This unbranded 21V drill closes the ranking, and it is the clearest illustration of everything above it. At under twenty-five pounds it undercuts almost everything, comes with two batteries and an 18-position torque collar, and claims a 45Nm maximum — a lot of specification for very little money. But the "21V" is the textbook trick: the no-load voltage of an ordinary 18V battery, quoted because it sounds bigger. Nothing about the pack is different from the honest 18V drills at the top; only the label is. The 45Nm torque claim, like all the budget figures here, has no standard test behind it, so treat it as optimistic. What truly places it last is evidence. With just three ratings there is effectively no track record — far too little to judge how it performs or lasts. We do not reject a product for being new, but on a tool you want to trust with a wall plug or a heavy screw, three reviews is not enough to lean on, and the better-proven drills above are the safer spend. Everything on this page comes from the Amazon listing rather than our own testing. Pros: Very cheap at under £25; Two batteries and an 18-position torque collar; 45Nm claim for the money; Fine in principle for the lightest jobs Cons: "21V" is an 18V pack read unloaded; Only 3 ratings — effectively no track record; Unstandardised, optimistic torque claim; No brand or tool ecosystem ## Verdict Buy a cordless drill on its battery and its brand honesty, not its voltage sticker. An "18V" and a "21V" drill run the same five-cell pack; the number that changes your day is the amp-hours (how long it lasts) and whether the motor is brushless (more power and life from the same charge). For most homes the Ryobi ONE+ is the safe pick — an honest 18V, a complete kit and one of the deepest review pools anywhere, feeding a huge battery ecosystem. If you want more muscle, the brushless Makita DHP484Z is the step up; if you just need to hang shelves and build flat-pack, the honest little Terratek does it for under twenty-five pounds. And if a listing leads with 20V or 21V, translate it to 18V in your head and judge the rest on its merits. Everything here comes from the Amazon listings, not our own testing.
