The best cordless angle grinders, compared.
Top pick: Dong Cheng DCSM03-125 kit Best value: DCA ADSM06-125 125 mm kit – About £56.98 for a complete 125 mm brushless kit with one 4.0 Ah pack, a charger, discs, and a case. Reviewers report about 20–30 minutes from a full pack. Updated October 2026.
A cordless angle grinder spins a disc at a right angle to the body so you can cut or grind metal without a mains lead. The amazon.co.uk split is a 115 mm or 125 mm kit with a battery, a bare 18 V body for an XR pack you already own, or a 75 mm or 76 mm mini for thin material in a tight gap. Judge a tool by a guard that locks, a matching bore, and a pack that lasts more than one short cut. Do not rank on rpm. 19,500 rpm on a 76 mm disc is not more cutting power than 8,500 rpm on 125 mm. Disc class and kit versus bare are in the [cordless angle grinder buying guide](/hub/sanders/cordless-angle-grinder/sub/cordless-angle-grinder-buying-guide). On these amazon.co.uk listings the useful split is disc class, then whether a battery is in the box. The NANWEI, the Seesii and the SoarFly include two 4.0 Ah packs.

Personal buying guide
Question 1 of 2
Which batteries do you already own?
The Dong Cheng DCSM03-125 is a 20 V brushless 125 mm tool listed at 8,500 rpm and £62.99, with 4.9 stars from 40 amazon.co.uk reviews. Reviewers use it on fencing wire, padlocks and mower blades, and they praise the case, guard adjustment and accessories when those parts are actually in the box. The included-components line says only “Angle Grinder”, so a second battery and the discs are not confirmed, even though the bullets describe a 4,000 mAh pack. It has a single stated speed. A UK reviewer who expected variable speed says the tool does not have it. Power and spindle-lock buttons are fiddly with gloves, and the single pack is the limit once it is flat. One listing field still says corded, which conflicts with the cordless title, and 40 reviews is a small base for a 4.9 average.
Pros
Cons
Best for: Occasional 125 mm DIY if you accept a 40-review sample and check the box on arrival.
Less suitable: Buyers who need two confirmed batteries or a variable-speed control.
Specifications
Common questions
Is the Dong Cheng DCSM03-125 variable speed?
The listing states 8,500 rpm and does not list speed steps. A UK reviewer who expected variable speed says it does not have it.
Does the listing confirm two batteries?
The bullets describe a 4,000 mAh pack. The included-components line says only “Angle Grinder”. Reviews mention a case and sometimes a spare pack, so a second battery is not confirmed.
The Ryobi R18AG-0 is an 18 V ONE+ 115 mm bare body at £66.65, listed at 7,500 rpm, with 4.7 stars from 4,468 amazon.co.uk reviews and rank 1 in Angle Grinders on the stored amazon.co.uk listing. Reviewers who already own ONE+ packs use it to cut steel and to rake patio grout, and one grout job lasted about 30 minutes on a 5 Ah pack. Several describe it as lighter and smoother than an old mains grinder, and brushless is not stated. The bullets name a tool-less guard and a three-position side handle, and they do not name a clutch. A “4 Horsepower” line on the listing is not a usable spec. One reviewer could not unlock the disc and snapped the spanner. Battery and charger are excluded, and the review count is still the widest in this set. The 115 mm disc and the missing clutch line keep it level with the DeWalt on those two points.
Pros
Cons
Best for: A Ryobi ONE+ owner who already has 115 mm discs and a 4.0 Ah or 5.0 Ah pack.
Less suitable: A buyer who needs a 125 mm disc, a named clutch, or a first battery.
Specifications
Common questions
Does the Ryobi R18AG-0 include a battery?
No. The title says battery and charger excluded, and the bullets say bare unit. It is for Ryobi 18 V ONE+ packs you already own.
What disc size and speed does the listing state?
The highlight says 115 mm and 7,500 rpm, for cutting and grinding metal. Brushless is not stated. A horsepower field reading “4 Horsepower” is not treated as a real spec. One reviewer could not unlock the disc and snapped the spanner.
The DeWalt DCG407N-XJ is an 18 V XR brushless 125 mm body at £107.50, tool only, with 4.7 stars from 78 amazon.co.uk reviews. It is the top pick in this set when you already run DeWalt 18 V XR packs. Reviewers fit 4 Ah and 5 Ah packs from other DeWalt tools, and several praise the balance for cutting, including professional use in dust and weather. The bullets name an electronic clutch that reduces kickback if the disc pinches, plus mesh debris covers and a two-position side handle. A maximum rpm is absent from the technical table, so you cannot check a disc’s marked speed against a figure on this listing. One buyer received an Allen key instead of the pin wrench and could not change the disc. There is no battery or charger in the box, and the clutch line is a listing claim rather than a lab measurement.
Pros
Cons
Best for: A DeWalt 18 V XR owner who wants a 125 mm body and will match the disc to the speed in the manual.
Less suitable: A first grinder with no batteries, or a price comparison against a complete kit.
Specifications
Common questions
Does the DeWalt DCG407N-XJ include a battery?
No. The title says tool only and the included-components field says no. You need a DeWalt 18 V XR pack and charger. Reviewers report using packs from other DeWalt tools.
What safety feature does the listing name?
The bullets name an electronic clutch that reduces kickback if the disc pinches, plus mesh debris covers and a two-position side handle. A maximum rpm is not in the technical table. One reviewer received the wrong key and could not change the disc.
The TEENO TEENO-3608 is a 16.8 V 76 mm mini at £39.99 with two 2,000 mAh batteries, six 76 mm cutting discs and a case, scoring 4.4 from 46 amazon.co.uk reviews. The listing limits it to domestic light-duty cutting and says it is not the tool for continuous cutting of thick metal. Reviewers use it on tiles, thin metal, rust and a carpet trim, and they like the weight in a small space. Several say it lacks power for the cut they wanted, and the batteries feel weak. One tool stopped before the first disc was worn. A buyer could not see where to get a replacement pack. The bore is 10 mm, the stated speed is 19,500 rpm, and listed power is 350 W. The included-components field only says “1”, so the bullet list is the fuller source for the box.
Pros
Cons
Best for: Tiles, rust and thin metal in a cupboard or a tight corner.
Less suitable: Brackets, rebar, or any continuous cut in thick steel.
Specifications
Common questions
Can the TEENO mini cut thick steel?
The listing says it is for domestic light-duty cutting and is not recommended for continuous cutting of thick metal or intensive professional use. It takes 76 mm discs with a 10 mm bore.
What is included?
The bullets list the grinder, two 2,000 mAh batteries, a charger, six 76 mm cutting discs, a screwdriver, a wrench, a manual and a plastic case. The included-components field only says “1”, so the bullet list is the fuller source.
Across 87 amazon.co.uk reviews, rated 4.3, the DCA ADSM06-125 handles short metal cuts as a 125 mm brushless kit. At £56.98 the listing includes one 4.0 Ah battery, a 2 A charger, cutting and flap discs, and a plastic toolbox. Reviewers describe quick cuts, a handy case, and balance that is manageable for a brief job, often set against an older corded grinder. The stated speed is 8,500 rpm with a 22 mm (7/8 in) bore, so a disc has to be marked at or above that speed. Runtime is the complaint that recurs: reviewers report about 20–30 minutes from a full pack, against a manual claim of roughly 120 minutes. The charger takes about two hours, and one buyer found a spare grinder cheaper than a spare pack. It also felt heavy to a first-time user, and the anti-restart line is a listing statement rather than a measured result.
Pros
Cons
Best for: Short DIY metal cuts when you have no battery platform and want a complete 125 mm kit around £57.
Less suitable: All-day cutting on a single pack, or a DeWalt XR owner who only needs a body.
Specifications
Common questions
Does the DCA kit include a battery and a case?
Yes. The amazon.co.uk listing includes one 4.0 Ah battery, a 2 A charger, cutting and flap discs, and a plastic toolbox. It does not include a second battery.
What disc size does it take?
The listing states 125 mm wheels with a 22 mm (7/8 in) bore, and an M14 spindle in the included-components line. Use a disc marked at or above 8,500 rpm.
The Dong Cheng DCSM04-125 is a 20 V 125 mm kit at £67.99 with one 4.0 Ah battery, a 2 A charger, two guards, discs and a case, and 4.3 stars from 50 amazon.co.uk reviews. The bullets describe Dynamic Safety Control as a cutoff if the wheel binds, which remains a listing claim. One reviewer cut metal chair legs without the tool stalling, and praised the balance and the case. Battery life is the main complaint, and the kit includes a single pack. A buyer who had also seen a Wickes-badged version questioned the price difference. The listing states 9,000 rpm and a three-speed claim. The listed weight of 5.85 kg is far above the 2.3–2.6 kg bare bodies in this set, so treat it as an unverified listing figure. The UK titles that were read show no repeated dead-on-arrival cluster.
Pros
Cons
Best for: A 125 mm kit buyer who wants a named cutoff on the listing and will budget a second pack.
Less suitable: Someone who needs two batteries in the box, or a DeWalt owner who only needs a body.
Specifications
Common questions
What does DSC mean on this Dong Cheng listing?
The bullets describe Dynamic Safety Control as a system that detects wheel binding or kickback. That is a listing claim, not a lab result. The kit also lists a standard guard and an anti-splash guard.
How many batteries are in the box?
One 4.0 Ah battery and a 2 A charger. UK reviews praise the case and ask for a spare pack because runtime is the weak point.
The NANWEI NW-A8132 is a 20 V 125 mm brushless kit at £65.99 with two 4.0 Ah batteries and speeds of 5,000, 7,000 and 9,800 rpm, scoring 4.2 from 86 amazon.co.uk reviews. Reviewers liked the variable speed for small projects and tiling, and some kept the tool after expecting a throwaway. One buyer’s existing 5 Ah pack worked, though the brand of that pack is not confirmed. Genuine Makita batteries would not lock for a UK reviewer. The listing names Makita-style codes in one bullet and says in the next that the 20 V packs are only for NANWEI tools. The guard would not fit for one buyer because the instructions assumed a recess that was not there. Included cutting discs were called useless, and one case arrived broken. The two batteries are the useful part of the price.
Pros
Cons
Best for: Short 125 mm jobs on NANWEI’s own packs, with separate discs bought for steel.
Less suitable: A Makita-platform owner, or anyone planning to cut steel with the included discs.
Specifications
Common questions
Does the NANWEI kit work with Makita batteries?
Do not rely on it. One bullet lists Makita-style pack codes, and the next says the 20 V packs are only for NANWEI tools and are not compatible with Makita. A UK reviewer says genuine Makita packs would not lock.
What is in the box?
Two 4.0 Ah batteries, a charger, cutting and grinding discs, a side handle, a wrench, a manual and a storage case. One reviewer could not fit the guard, and another called the included cutting discs useless.
The Seesii AN03K is a 21 V brushless 4-1/2 inch kit at £79.99 with two 4.0 Ah batteries and speeds of 5,000, 7,500 and 10,000 rpm. Across 726 amazon.co.uk reviews it sits at 4.0 stars, the widest sample among the own-brand kits here. Reviewers finish a mortice-lock bolt and other small jobs when the pack is full, and some call the three speeds good value. Several buyers say the batteries flatten quickly. Reports include a pack that arrived damaged, a pack that would not charge, tools that stopped after a handful of uses, and a burning smell within seconds of a first start. A swivel was described as very loose, and a spindle lock stuck on during use. Two batteries shorten the wait between charges. They do not erase a 4.0 average or those early-failure reports, and kickback control is not stated.
Pros
Cons
Best for: Short 4-1/2 inch jobs when you want two packs in the box and can return a faulty unit.
Less suitable: Daily site work, or a buyer who wants a named clutch.
Specifications
Common questions
How many batteries does the Seesii kit include?
The listing includes two 4,000 mAh batteries, a charger and a carrying bag, plus cutting wheels, flap wheels and a wood-carving wheel.
Does it have more than one speed?
Yes. The listing states 5,000, 7,500 and 10,000 rpm. UK reviews also mention weak battery life and, in some cases, early failure.
The SoarFly KF2T0011EU-AG is a 115 mm kit at £86.99 with two 4.0 Ah batteries and claimed speeds of 5,000, 7,500 and 10,000 rpm, scoring 3.9 from 48 amazon.co.uk reviews. Reviewers call it lighter than a mains grinder for small DIY, and the two packs are the part they actually use. The bullets claim stall protection, an electronic brake, and about 60–80 minutes of heavy use. Those runtime and brake lines are manufacturer sentences, not timed UK tests. The technical wattage field incorrectly says 4,000 milliamp hours, and voltage is not stated. Plastics feel fragile to reviewers, one battery arrived damaged, the charger feels cheap, and the guard and manual were awkward. At £86.99 it costs more than several 125 mm kits in this set while keeping you on 115 mm discs.
Pros
Cons
Best for: Light 115 mm work when you specifically want two packs and will inspect the guard before use.
Less suitable: A buyer comparing the price with a cheaper 125 mm kit, or anyone reading the wattage field as motor power.
Specifications
Common questions
How long do the SoarFly batteries last?
The bullets claim about 60–80 minutes of heavy use and about two hours to charge. That is a manufacturer claim. UK reviews talk about the two packs being useful, not about a timed test. The technical wattage field incorrectly says 4,000 milliamp hours.
What disc size is it?
115 mm, with 4-1/2 inch wheels in the included-components line. The listing claims stall protection, an electronic brake and a two-step power lock. Reviews also mention a weak manual and fragile plastics.
The Rivlox 125 mm body at £28.49 is tool only and claims fit on named DeWalt packs, including DCB201, DCB203, DCB204, DCB205, DCB230 and DCB206. Across 33 amazon.co.uk reviews it scores 3.9. One buyer cut a bolt or drop-link on a 5 Ah pack, and another shaped a bathroom tile. A third returned the tool because an 18 V DeWalt pack did not fit, while a further review says a DeWalt pack did fit, so fit is unconfirmed. Reviewers also describe low torque on harder cuts, a stiff top switch, and the tool stopping under load in a way they read as overheating. The listing claims three speeds up to 9,000 rpm and a low-voltage cutoff. There is no charger in the box. At £28.49 the body is inexpensive only after the pack you own locks and stays locked.
Pros
Cons
Best for: A trial body you can return the same week if your XR pack will not lock.
Less suitable: Anyone who needs a guaranteed DeWalt fit, or a first kit with batteries included.
Specifications
Common questions
Will this Rivlox body take a DeWalt battery?
The listing names DCB201, DCB203, DCB204, DCB205, DCB230 and DCB206 and says the battery is not included. One UK reviewer returned it because their 18 V DeWalt pack did not fit. Another says a DeWalt pack fitted. Fit is not guaranteed.
Is a charger included?
No. Included components are the angle grinder only. You need a compatible pack and a charger you already own.
The Rivlox GJ25903-2UK is a 12 V brushed mini at £22.94 with two 1.5 Ah batteries, five cutting discs and a listed 75 mm wheel at 19,500 rpm. Across 224 amazon.co.uk reviews it scores 3.6. Buyers use it on a rusted bolt or padlock in a small gap, and a few short bolt cuts finished when they kept the pressure light. The disc slows if you lean on it, and one user reported about 10 minutes of wood sanding from a battery. Reviewers describe the tool as much smaller than the advert, and one buyer said it was the wrong choice for cutting slates. The spindle is M5, so a full-size 22 mm disc does not fit. A slide switch on this compact body can stay running if the tool is snatched, and kickback control is not stated. Treat 19,500 rpm as a small-disc figure, separate from the cutting power of a 125 mm grinder.
Pros
Cons
Best for: One rusted bolt or padlock where a full-size guard will not fit.
Less suitable: Brackets, rebar, slate, or any cut that needs sustained pressure.
Specifications
Common questions
Is this 12 V Rivlox a full-size angle grinder?
No. The highlight says 75 mm and the listing says a brushed 12 V motor with an M5 spindle. Reviews describe it as very small and say it slows if you press hard.
Are batteries included?
Yes. The listing includes two 1.5 Ah batteries, a charger and five cutting discs. A case is not stated.
The DEWINNER DE-3608-GUK-N is a 76 mm mini at £33.99 with two 16.8 V 2,000 mAh batteries, six discs and a listed 19,500 rpm. Only 11 amazon.co.uk reviews sit behind the 3.3 score, so each comment is a single report. Buyers used it on tiles, grout, wooden battens and rusty bolts in places a full-size body will not reach, and one liked an instant stop. The bullets say brushless, while a UK review says the motor is brushed, so that claim stays unconfirmed. The guard came loose after about 20 minutes and nearly caught a thumb, and a saw attachment shook. The bore is stated as 10 mm with a 76 mm disc, so a standard 22 mm wheel does not fit. Eleven reviews is too small a base to treat the rating as settled.
Pros
Cons
Best for: Light DIY in a gap a 115 mm guard cannot enter, after you check that the guard locks.
Less suitable: Thick steel, or anyone who wants a confirmed brushless motor and a larger review base.
Specifications
Common questions
Is the DEWINNER a full-size grinder?
No. The listing is a 76 mm tool with a 10 mm bore and two 16.8 V 2,000 mAh batteries. It is a mini kit, and the review count is only 11.
Is the motor brushless?
The bullets say brushless. A UK review says it is a brushed DC motor. Both lines are on the listing and in the reviews, so brushless is not confirmed.
Shelf prices, stars, and review counts are the amazon.co.uk figures stored for these twelve listings. The editorial score is a 0–100 figure from those stars, damped where the stored reviews describe short runtime, a guard that came loose, a pack that would not fit, or a listing that contradicts itself. It is not a laboratory test, and price does not set the score. We did not time a battery or measure vibration. A brushless line, a clutch name, or a “fits DeWalt” claim is kept only with the contradictory bullet or review where one exists.
Disc class
25%115 mm or 125 mm is the class for steel work. A 75 mm or 76 mm mini is for a tight space and thin material. The TEENO listing says it is not for continuous cutting of thick metal. A 125 mm disc does not go on a 115 mm guard.
Kit or bare body
25%A kit includes a pack. A bare DeWalt or Ryobi body is priced before the battery you already own. A “fits DeWalt” or “fits Makita” line is not scored as a fit when the listing or a UK review contradicts it.
Guard, clutch, and switch
20%A guard that locks is the first safety check. DeWalt names an electronic clutch. Dong Cheng DCSM04-125 names a DSC cutoff. Ryobi names a tool-less guard and does not name a clutch. A slide switch can stay running if the tool is snatched.
Runtime you can believe
15%Most kits here have one or two 4.0 Ah packs. DCA reviewers describe about 20–30 minutes against a longer manual claim. A second pack is budgeted in the judgement. A manufacturer runtime sentence is not treated as a timed result.
UK review evidence
15%Stars and review counts come from the amazon.co.uk listing. A high rpm on a 76 mm disc is not scored as more cutting power than a 125 mm tool. No vibration or noise figure is invented for a named model.
Start with disc class, then whether a battery is in the box, then whether the guard locks. Rpm on the title is a weak guide. A 75 mm mini at 19,500 rpm is not a stronger cutter than a 125 mm tool at 8,500 rpm. The twelve listings below are amazon.co.uk pages, with the prices and review counts stored for this comparison. A brushless line, a clutch name, and a “fits DeWalt” claim stay as listing sentences unless a UK review confirms them. If the guard will not lock, stop.
A cordless angle grinder drives a disc at a right angle to the body so you can cut or grind metal without a mains lead. On these amazon.co.uk listings the useful split is disc class, then whether a battery is in the box. Full-size kits here are the DCA, both Dong Cheng models, the Seesii, the NANWEI, and the SoarFly. Each includes a pack. The Seesii, the NANWEI, and the SoarFly include two 4.0 Ah packs. Bare bodies are the DeWalt DCG407N-XJ at 125 mm and the Ryobi R18AG-0 at 115 mm.
The DeWalt at about £107.50 and the Ryobi at about £66.65 are bodies only. The DCA at about £56.98 includes a 4.0 Ah pack, a charger, discs, and a case. A lower body price is not a cheaper finished kit.
The Rivlox 125 mm body names DeWalt pack codes, and one UK reviewer returned it because an 18 V DeWalt pack did not fit. NANWEI names Makita-style codes and also says the packs are only for NANWEI tools. A UK reviewer says genuine Makita batteries would not lock.
19,500 rpm on a 76 mm disc is not more cutting power than 8,500 rpm on 125 mm. A free cutting disc is not a grinding wheel. DCA reviewers describe about 20–30 minutes from one 4.0 Ah pack, against a longer manual claim. Budget a second pack.
115 mm or 125 mm does real steel work. In this set that is the DeWalt and the Rivlox 125 mm bodies, the Ryobi and the SoarFly at 115 mm, the Seesii 4-1/2 inch kit, and the 125 mm kits from DCA, Dong Cheng, and NANWEI. A 75 mm or 76 mm mini (Rivlox 12 V, DEWINNER, TEENO) is for a tight space and thin material. The TEENO listing says it is not for continuous cutting of thick metal. Do not fit a 125 mm disc on a 115 mm guard, and do not side-grind with a cutting disc.
If you have no batteries, a 125 mm kit around £57 to £80 is the honest price, not a bare body. The DCA includes one 4.0 Ah pack. Both Dong Cheng kits are sold as one-pack sets, though the DCSM03-125 components line only says “Angle Grinder”. Seesii, NANWEI, and SoarFly include two 4.0 Ah packs. The DeWalt DCG407N-XJ and the Ryobi R18AG-0 are bare. Reviewers fit existing XR and ONE+ packs, including 4.0 Ah and 5.0 Ah.
Three typical situations, each with a recommendation from this comparison.
You want a 125 mm kit around £57 to £80, not a bare-tool price. The DCA ADSM06-125 is the best value at about £56.98, with one 4.0 Ah pack, a charger, discs, and a case. Reviewers report about 20–30 minutes from a full pack, so a longer job needs a second battery.
You already have XR packs and want a 125 mm body. The DeWalt DCG407N-XJ is the top pick at about £107.50, tool only, with an electronic clutch named in the bullets. It is the wrong comparison if you still need a first battery and charger.
A full-size guard will not fit, and the metal is thin. The TEENO 76 mm mini at about £39.99 states a light-duty limit and includes two batteries and a case. Stop when the steel gets thick. A 19,500 rpm figure is not full-size cutting power.
The top pick is the DeWalt DCG407N-XJ, a 125 mm brushless body at about £107.50, if you already run DeWalt 18 V XR packs. The bullets name an electronic clutch, the listing shows 4.7 from 78 reviews, and the box has no battery. The best value is the DCA ADSM06-125 at about £56.98, a complete 125 mm kit with one 4.0 Ah pack, discs, and a case, with 4.3 from 87 reviews. Reviewers describe short metal cuts and about 20–30 minutes from a full pack. A Ryobi ONE+ owner is looking at the R18AG-0 body, not the DeWalt price. A 75 mm or 76 mm mini is for a bolt in a tight gap, and the TEENO listing rules out continuous cutting of thick metal.
DCA ADSM06-125 125 mm kit
About £56.98 for a complete 125 mm brushless kit with one 4.0 Ah pack, a charger, discs, and a case. Reviewers report about 20–30 minutes from a full pack.
