The best DeWalt angle grinders, compared.
Top pick: DeWalt DCG406N-XJ – 125 mm bare body with a brake and clutch named, 4.7 from 534 ratings, at about £131.90. Best value: DeWalt DWE4036-GB – Corded 115 mm grinder at about £59.99, with both guards named, for work beside a 230 V socket. Updated October 2026.
An angle grinder spins a bonded abrasive disc so you can cut and grind metal, and sometimes masonry, when a hacksaw is too slow. A suitable tool shows the disc diameter on the rating plate, a guard that stays fitted, and a flange that keeps the disc on the spindle. Match the bore, the thickness and the maximum speed of the disc to that plate. Do not fit a larger disc than the guard is made for. A mains tool plugs into a UK 230 V socket. A battery body is a complete purchase only when you already own packs of a useful capacity, or you add them. A tool-only listing leaves the battery and the charger out of the box. On a construction site, use cordless tools or a 110 V centre-tapped supply. Isolate the tool before a disc change, keep the guard on, and wear eye protection to BS EN 166. At work, mounting abrasive wheels needs training under PUWER 1998, and HSG17 recommends a written record. A course certificate is not automatically competence.

Question 1 of 2
Where will you use it?
Across 534 amazon.co.uk ratings, the DCG406N-XJ holds 4.7 and UK reviewers describe a compact 125 mm brushless body for short jobs away from a cable. The listing states 9,000 rpm, an electronic brake that stops the wheel when the trigger is released, and an electronic clutch if the disc pinches or stalls. Reviewers who wear gloves often prefer the paddle they describe to a slide switch, and several mention a speed nut so they are not looking for a separate spanner. The included-components cell does not list a battery or a case, and people who tried a 2.0 Ah pack say it goes flat in minutes. One detailed review reports the motor cutting out after overheating and then needing a restart. Amazon's 3,600 W cell is not a usable power figure on an 18 V tool, so this body earns its place when you already own a 4 Ah or 5 Ah pack.
Pros
Cons
Best for: You already own DeWalt 18 V XR packs of 4 Ah or 5 Ah and want a 125 mm bare body with a brake named on the listing.
Less suitable: You need a battery and a case in the box, or you want a mains tool that stays on a socket for continuous cutting.
Specifications
Common questions
Does this listing include a battery?
The included-components cell does not list a battery. UK reviews call the DCG406N-XJ a bare unit and say a case is not included.
What disc size does the title state?
The title states 125 mm. The attribute table states a maximum rotational speed of 9000 rpm.
Which safety features are in the bullets?
The bullets name an electronic brake when the trigger is released, and an electronic clutch if the disc pinches or stalls.
The DCG407N-XJ is a 125 mm 18 V brushless tool-only body at about £107.50, with 4.7 from 78 amazon.co.uk ratings. UK reviewers say it runs on batteries from a DeWalt drill and feels light for DIY cutting, including one person who stripped a garden table. The item highlight states slide-switch operation, and the bullets name an electronic clutch without naming a brake, so you should not assume the stop-on-release behaviour of the DCG406. The dewalt.co.uk page title says paddle and mixes in a two-battery kit, so that page and the Amazon highlight are not the same claim. A longer UK review says that slide switch collects dust. The included-components row says no battery. One buyer's locking nut loosened after about two weeks until the disc would not stay on, and the tool was returned. Another unit arrived without the side handle, and one key in a box did not fit.
Pros
Cons
Best for: You already own DeWalt 18 V packs, you want the lower bare-body price, and a slide switch is the control you prefer.
Less suitable: You want a brake named on the listing, or you have no 18 V packs yet and would still be buying batteries.
Specifications
Common questions
Is a battery included?
The title says tool only. The included-components row says no.
What switch does the listing describe?
The item highlight says slide switch operation. The dewalt.co.uk page title says paddle, so the two pages do not agree.
Does the listing name a brake?
The bullets name an electronic clutch. They do not name a brake.
The DCG404N-XJ is the compact 125 mm 18 V brushless tool-only body, listed at about £188.05. Only 13 amazon.co.uk ratings sit behind the 4.6 line, and two of them are longer than a sentence, so the sample is thin beside the DCG406. The bullets name an electronic brake, an electronic clutch and electronic soft start. The box list includes a side handle, a clip-on grinding guard, a cutting guard and a hex wrench, and it does not include a battery. One detailed UK review calls the tool light and comfortable for small occasional DIY. The same reviewer reported about 10 minutes from a fully charged genuine pack during professional cutting, with two packs flat in under 20 minutes, and then went back to a mains grinder. The listing's first-available date is 6 May 2026. The compact body and the named soft start are real differences on the page, and they are not a measured runtime.
Pros
Cons
Best for: You already own 18 V packs and the compact body, with a brake and soft start named on the listing, is the reason you would pay more.
Less suitable: You want a large review sample, the lowest shelf price, or a runtime you can treat as measured.
Specifications
Common questions
Is a battery in the box?
The title says tool only. The listing says batteries are required and are not included.
What is listed in the box?
Side handle, clip-on grinding guard, cutting guard and hex wrench.
Which safety features are in the bullets?
Electronic brake, electronic clutch and electronic soft start.
The DWE4036-GB is the corded 750 W, 115 mm grinder in this set, listed at about £59.99 with 4.5 from 41 amazon.co.uk ratings. Reviewers describe a slim body that cut concrete roof tiles and helped take a caravan apart, and one found less vibration than their previous grinder. The bullets name a no-volt release, so the switch has to be reset after you plug in, plus a cutting guard and a grinding guard. You still unplug the tool before you change a disc. A 125 mm disc does not belong on this 115 mm spindle, and the manual's 11,800 rpm is the speed to match, rather than a marketing line of 1,800 rpm. One review says the outer flange loosened until the cutting disc left the spindle, and another says a guard broke. For work beside a UK socket, with 115 mm discs, it is the complete low-price listing here, and it is a poor fit as a 110 V site grinder.
Pros
Cons
Best for: You work beside a UK 230 V socket and 115 mm discs are enough for the cuts you actually make.
Less suitable: A construction site that should be on cordless tools or 110 V, or any job that needs a 125 mm disc.
Specifications
Common questions
Is this a cordless grinder?
No. The listing says corded electric, 750 W, and the title says 115 mm.
What guards does the listing name?
The bullets say it is supplied with cutting and grinding guards.
What does the switch bullet say?
It is a no-volt release switch. The tool should not restart just because it is plugged in. The switch has to be reset.
Four amazon.co.uk listings, captured on 19 October 2026, were scored from the stored pages. There is no laboratory test. Stars are the listing line, not a workshop trial. Each score uses four parts: listing stars out of 40, the review-sample band out of 20, category fit out of 22, and a price band out of 9. The highest total is the top pick. Among the rest, the strongest price-band score is best value. One of each. A bare-tool price is not the cost of batteries. The weights below are those four parts scaled so they sum to 100.
Listing stars
44%The amazon.co.uk star line, as a share of the score. A 4.7 line scores higher than a 4.5 line. Stars are not a workshop trial and they are not a durability test.
Review sample
22%How many people have rated the listing. 200 or more ratings take the full share. 50 to 199 take half of that share. 10 to 49 take a smaller share. A thin sample stays a thin sample.
Category fit
24%Each row is a DeWalt angle grinder in this set, so fit is flat. A named brake, clutch or guard does not add fit points. Those details stay in the table.
Price band
10%Shelf price on 19 October 2026. Under £70 takes the full price share. Under £120, under £160, and £160 and above step down. A bare cordless price is not the cost of batteries.
Buy the supply and the disc before you buy a star line. A 230 V workshop grinder is not a 110 V site tool. A bare 18 V body is not a complete purchase until you own a pack. None of these scores is a laboratory test.
An angle grinder cuts and grinds with a spinning abrasive disc. Buyers use one on metal, and sometimes on masonry. This set is one corded 115 mm tool and three bare 125 mm 18 V bodies. Judge a listing by the guard, a flange that stays tight, the switch, and a disc rated for the tool's speed. Shelf prices and stars are the amazon.co.uk listings captured on 19 October 2026. There is no laboratory test. Start with where you work. The DeWalt DWE4036-GB is a 230 V workshop tool, listed at 750 W.
An N suffix and the words tool only mean no battery and no charger. UK reviews say a 2.0 Ah pack goes flat in minutes. Plan on 4 Ah or 5 Ah before you treat the shelf price as the working price.
The 3,600 W figure on the DCG406 listing is not a usable power figure on an 18 V tool. The DCG406 manual states 800 W output and 9,000 rpm. Use the manual, not that cell.
The DWE4036-GB is 115 mm. A 125 mm disc does not belong on that spindle. Match the bore, the thickness and the maximum speed. The manual states 11,800 rpm, not the marketing line of 1,800 rpm.
UK mains are nominally 230 V, and a mains plug is BS 1363. The DWE4036-GB is that pattern: corded, 750 W, 115 mm, with a no-volt release. HSE guidance for construction sites asks for cordless tools or a 110 V centre-tapped supply. Do not call this 230 V grinder a 110 V site tool. The other three listings are bare 18 V bodies at 125 mm. They are a complete purchase only when you already own DeWalt 18 V packs, or you add a 4 Ah or 5 Ah pack and a charger.
Read the bullets on that ASIN, not a different kit page. The DCG406N-XJ names a brake and a clutch, and UK reviews describe a paddle. The DCG407N-XJ Amazon highlight says a slide switch, and its bullets name a clutch, not a brake. The DCG404N-XJ names a brake, a clutch and soft start, plus both guards and a hex wrench, and it does not name the switch. The DWE4036-GB names a no-volt release and both guards. A bare cordless price is the body only.
Three typical situations, each with a recommendation from this comparison.
You want a 125 mm bare body and a brake named on the listing. The DeWalt DCG406N-XJ is the top pick at about £131.90, with 4.7 from 534 ratings. The box does not list a battery. UK reviews say a 2.0 Ah pack goes flat in minutes, so plan on 4 Ah or 5 Ah.
You want a corded tool and 115 mm discs are enough. The DeWalt DWE4036-GB is best value at about £59.99, with a no-volt release and both guards named. It is 4.5 from 41 ratings. It is a 230 V workshop tool, not a 110 V site grinder.
You already own 18 V packs and a slide switch is the control you prefer. The DeWalt DCG407N-XJ is about £107.50, with 4.7 from 78 ratings. The bullets name a clutch. They do not name a brake. No battery is in the box.
The top pick is the DeWalt DCG406N-XJ at about £131.90. It is a 125 mm 18 V brushless bare body with a brake and a clutch named on the listing, and 4.7 from 534 amazon.co.uk ratings. The best value is the DeWalt DWE4036-GB at about £59.99, a corded 750 W 115 mm grinder with both guards named, if you work beside a 230 V socket. The DCG407N-XJ is the lower bare 125 mm price at about £107.50, with a slide switch and no brake named. The DCG404N-XJ names a brake, a clutch and soft start, at about £188.05, with 13 ratings. None of these scores is a laboratory test, and a bare cordless price is not the cost of batteries.
