The best angle grinders, compared.
Top pick: Bosch UniversalGrind 750-115 Best value: DCA ASM18-115 – About £29.99 for 860 W, 1.67 kg, six discs, two guards, and a pin spanner, at 4.3 from 74 reviews. Updated October 2026.
An angle grinder is a handheld power tool with the spindle at roughly a right angle to the motor. In the UK you buy one to cut metal, tile, or masonry, or to grind a weld. Small machines use an M14 spindle. Bores are commonly 22.2 mm or 22 mm. The usual classes are 115 mm (about 4.5 inch) and 125 mm (about 5 inch). A 230 mm body is a larger tool. Match the guard to the disc, and keep a spanner for wheel changes. A corded tool suits a socket. A battery kit suits a short cut away from one. A bare body only helps if you already own a compatible pack. No-load rpm is not the speed in the cut. UK mains are nominally 230 V, with a UK 3-pin plug and fuse. Unplug before a wheel change. Do not fit a toothed saw blade or a chainsaw disc. At work, PUWER 1998 still applies to abrasive wheels. Disc class, the lead, and the box are set out in the [angle grinder buying guide](/hub/tools/angle-grinder/sub/angle-grinder-buying-guide).

Question 1 of 2
Where will you cut?
The Bosch UniversalGrind 750-115, model 06033E2071, is about £44 with 4.7 from 111 amazon.co.uk reviews, the highest star line in this set. The included-components line names the grinder, three straight cutting discs, a side handle, a guard converter, and carton packaging, and the package weight is 2.66 kg. Wattage, no-load speed, and voltage are not printed in the technical block, so the 750 in the model name is not a watt figure you can quote from this listing. UK reviewers use the green DIY body for car work and tiling and call the price competitive with unbranded tools. The guard is fiddly, the instructions are weak, and there is no speed dial. One reviewer said it is not a mini tool despite the name. It suits a named-brand 115 mm cutter when the three discs matter more than a printed wattage.
Pros
Cons
Best for: A Bosch DIY 115 mm body when you want cutting discs in the carton and can accept missing watt and speed rows.
Less suitable: Matching a disc to a printed no-load speed, or anyone who wants a speed dial.
Specifications
Common questions
Are watts printed for the UniversalGrind 750-115?
No. The technical block has no wattage or no-load speed row. The model name in the included-components line is UniversalGrind 750-115.
What is in the box?
UniversalGrind 750-115, three straight cutting discs, a side handle, a guard converter, and carton packaging. Package weight is 2.66 kg.
Does it include a battery?
The batteries-included line says No. The power-source line says corded.
The Bosch Professional GWS 7-115 is a 720 W, 115 mm corded grinder at about £67.55, listed at 11,000 rpm, 240 V, and 1.9 kg, with a 176 mm grip in the bullets. Across 1,378 amazon.co.uk reviews the line is 4.6, the largest count in this set, and the 50 sampled review texts are marked United Kingdom. Reviewers use the narrow body in tight spaces and on stump, kerb, and paving cuts, and some report years of service including a brush change. The housing runs very hot after about 10 to 15 minutes, and more than one unit is described with a burning smell. The scope-of-supply bullet lists a guard, an auxiliary handle, flanges, and a two-hole spanner, and it does not list a disc. Reviewers also call the guard fiddly and the supplied handle a basic plastic one rather than the anti-vibration handle in pictures. It is the top pick here for a light named-brand 115 mm body, if you buy a disc separately and stop when the housing heats up.
Pros
Cons
Best for: Short cuts with a light 115 mm Bosch body when you already own discs.
Less suitable: Long unattended runs, or a first job that needs discs in the carton today.
Specifications
Common questions
Does the Bosch GWS 7-115 box include a disc?
No. The scope-of-supply bullet lists an auxiliary handle, backing flange, locking nut, protective guard, and a two-hole spanner. It does not list a disc.
What power and voltage are printed?
The technical lines say 720 W, 11,000 rpm, and 240 V. Item weight is 1.9 kg. Grip size in a bullet is 176 mm.
Is restart protection printed on this listing?
No. The captured bullets do not state restart protection, so that field stays open even if another Bosch page describes it.
The LiunxDromic UK3 is a 1,000 W, 125 mm corded grinder at about £44.64, listed at 12,000 rpm with a six-step claim from 2,000 to 12,000 rpm and an item weight of 1.91 kg. The star line is 4.5 from 32 reviews, and UK texts describe cuts through steel and thick paving slabs. A bullet kit lists cutting discs, grinding discs, a diamond blade, a flap disc, and a wood saw blade, while the included-components line says only the angle grinder. One UK reviewer said the sample arrived with a moulded UK plug, which the specification rows do not print. The wood saw blade needed a vice to remove in one review, and that blade is not approval to cut wood. Another reviewer reported the spindle lock seized on the first disc change, and a disc left the spindle when the tool was switched off during a kerb cut. Treat the 4.5 as a small sample with a serious disc-retention complaint, not as a reason to rank it above tools with hundreds of reviews.
Pros
Cons
Best for: Corded 125 mm metal or masonry only if you leave the wood blade in the bag and prove the spindle lock before the first cut.
Less suitable: Anyone who wants a large review sample, or a carton whose contents match a single included-components line.
Specifications
Common questions
What size disc does the LiunxDromic listing state?
The title states 125 mm. The technical speed line is 12,000 rpm and the wattage line is 1,000 W.
Does the box include a wood saw blade?
A bullet lists a wood saw blade and a diamond blade. The included-components line says only the angle grinder. A wood blade in the kit is not approval to cut wood.
Is a UK plug printed in the specification?
No voltage or plug standard is in the specification rows. One UK review says the sample had a moulded UK plug.
The DEWINNER DE-T1088 is an 850 W, 115 mm corded grinder at about £29.74, listed at 12,000 rpm, 240 V, and 2.61 kg. The star line is 4.3 from 716 reviews, the second-largest count in this set. UK reviewers cut roof tiles and box metal, and some praise the switch on a first mild-steel job. A bullet lists three grinding discs, two cutting discs, a flap disc, a spindle lock, and accidental-restart wording, while the included-components line says only Motor. More than one UK review says there was no spanner, or nothing to lock the spindle, so the disc would not come off. The handle felt too close to the disc for some buyers, and the guard had some play. It is a heavily reviewed budget 115 mm tool if the locking spanner is actually in your carton.
Pros
Cons
Best for: Occasional tile and box-metal cuts once you have confirmed a spanner is in the box.
Less suitable: A first disc change if the spindle will not lock.
Specifications
Common questions
What voltage is on the technical line?
240 volts. The title also says 220–240 V. Item weight is 2.61 kg and the wattage line is 850 W.
Does the bullet say the switch has restart prevention?
Yes. A bullet says accidental restart prevention. The included-components field, by contrast, says only Motor.
Why do reviews mention a spanner?
More than one UK review says there was no spanner, or nothing to lock, so the disc could not be changed. That is a review theme, not a count of every unit.
The C P CHANTPOWER CPAG590-UK is a 900 W, 115 mm corded grinder at about £30.54, with an item weight of 2.76 kg. The technical speed line says 11,000 rpm and a bullet says 12,000 rpm, so a disc maximum should clear the higher figure. The star line is 4.3 from 556 reviews. UK buyers use it on tile and, in one review, a long concrete trench, and some prefer the mains lead to owning a battery. A bullet lists two grinding wheels, two cutting wheels, a flap disc, a side handle, and a wrench, while the included-components field says only Adapter. The slide switch is the repeated complaint: hard in gloves, pressed at the back and then slid, and in some reviews it moves on its own or will not move. One reviewer called the guard useless, and supplied discs stuck so they had to be broken off. It is a widely reviewed cheap 115 mm kit if that switch action suits you.
Pros
Cons
Best for: Occasional 115 mm tile and metal near a socket, if you can work the slide switch.
Less suitable: Gloved work where a stiff slide switch gets in the way.
Specifications
Common questions
Which speed figure should you trust?
The technical line says 11,000 rpm and a bullet says 12,000 rpm. Both are listing text. Use the higher figure when you match a disc maximum speed.
How do UK reviewers describe the switch?
Several say the slide switch is hard. They press the back, then slide it. That is a review theme, not proof that every unit fails.
What wheels does the bullet list?
Two grinding wheels, two cutting wheels, one flap disc, a side handle, two carbon brushes, and a wrench. The included-components field says only Adapter.
The DCA ADSM06-125 is a 20 V brushless kit at about £56.98, listed at 630 W, 8,500 rpm, 125 mm, and about 2.37 kg with the battery fitted. The price includes one 4.0 Ah battery and a 2 A charger, and the listing says that charger takes about two hours. Across 87 amazon.co.uk reviews the line is 4.3. UK reviewers praise cordless metal cuts, the case, and the balance, and they put runtime near 20 to 30 minutes rather than a manual figure near 120 minutes. The box lists two cutting discs, four flap discs, two tool-free guards, and a side handle, and a bullet uses anti-restart wording. A first-time user called it a bit heavy, and there is no second battery. It suits short jobs away from a socket. It does not stand in for a corded grinder when the cut runs on.
Pros
Cons
Best for: Short cordless metal cuts when you do not already own a battery platform.
Less suitable: Long grinding beside a socket, or a job that needs a second pack.
Specifications
Common questions
Does this DCA price include a battery?
Yes. The listing includes one 4.0 Ah battery and a 2 A charger. It is not a bare body.
What disc size and speed are printed?
The title states 125 mm and 8,500 rpm. The wattage line is 630 W and the voltage line is 20 V.
Is restart protection stated?
A bullet uses the wording anti-restart protection. That is a listing claim, not a laboratory test.
The DCA ASM18-115 is an 860 W corded 115 mm grinder at about £29.99, listed at 11,800 rpm and 1.67 kg, with an M14 spindle and a 22.2 mm bore. Across 74 amazon.co.uk reviews the line is 4.3, and UK buyers describe cuts on porcelain, tiles, and deck joists rather than day-long site work. The included-components line lists two cutting discs, four flap discs, a grinding guard, a cutting guard, an auxiliary handle, and a pin spanner. Reviewers call the body light next to heavier 115 mm grinders, though the guard is awkward to fit and a novice reviewer called the supplied discs poor. Noise is loud enough that one reviewer advised earplugs, and the instructions could be clearer. No voltage row confirms a BS 1363 plug. It is the best value in this set when you want a light corded 115 mm kit beside a socket, once you have checked the guard and the included discs.
Pros
Cons
Best for: Light corded cuts on tile and small metal near a socket, when a pin spanner and two guards need to be in the box.
Less suitable: Long noisy sessions, or a buyer who needs a printed UK plug standard before ordering.
Specifications
Common questions
What disc size does this DCA listing state?
The title and bullets state 115 mm, with an M14 spindle and a 22.2 mm bore.
Are discs included at about £29.99?
The included-components line lists two cutting discs, four flap discs, two guards, an auxiliary handle, and a pin spanner.
Is it cordless?
The power-source line says corded electric. No battery is listed.
The POSENPRO PPAG1200/125 is a 1,200 W, 125 mm corded grinder at about £33.99, with 230 V on the technical line and a six-speed dial from 3,000 to 12,000 rpm. Item weight is 2.51 kg, while a bullet says 1.8 kg, so the two figures should not be collapsed into one. The star line is 4.2 from 160 reviews. UK reviewers cut steel trunking and a padlock, some chose it for the dial, and an early review called it smooth. The switch is the recurring fault: it died in under a minute, stuck on so the user unplugged it, or failed after about an hour, and one motor burnt out on polishing mops. The included-components line lists one grinding wheel, a handle, a spanner, and two carbon brushes. A guard is not in the comparison fields. Buy it only if you will unplug the moment the switch misbehaves.
Pros
Cons
Best for: Occasional 125 mm metal cuts near a socket, if you stop and unplug at the first switch fault.
Less suitable: Polishing with mops, or anyone who needs a switch that stays reliable.
Specifications
Common questions
What voltage does POSENPRO print?
The technical line says 230 volts AC. The title states a 125 mm disc and 1,200 W.
Is the speed fixed?
A bullet says a six-speed dial from 3,000 rpm to 12,000 rpm. The maximum rotational speed line is 12,000 rpm.
How many discs are in the included-components line?
That line lists one tool-free grinding wheel, plus a handle, a spanner, two carbon brushes, and a manual.
The DEKOPRO 115 mm grinder is the lowest price in this set at about £25.99, listed at 900 W, 12,000 rpm, and 2.44 kg, with 220 V on the technical line. The star line is 4.1 from 236 reviews. UK reviewers cut a steel gate post and motorcycle frames, and some use it for short mortar jobs and a wire wheel. The package lists a wheel guard, a cutting guard, one grinding wheel, a wrench, and a side handle, and a bullet claims power-off protection after a supply cut. The gear head gets hot on longer runs, the switch is described as difficult and intermittent, and the wheel lock does not always hold. The cable is short. A 220 V line is not a confirmed BS 1363 plug, so check the plug in the listing photos. It is the cheapest 115 mm corded body here, and the heat and the switch are the reasons to keep each job short.
Pros
Cons
Best for: Short, low-cost 115 mm cuts after you have checked the plug in the photos.
Less suitable: Sustained grinding, or a socket that needs a long lead.
Specifications
Common questions
What voltage does DEKOPRO print?
The technical line says 220 volts AC. UK mains are 230 V, so check the plug in the listing photos before you rely on it.
Is a restart feature stated?
A bullet says power-off protection so the tool does not start again after a supply cut. That wording is the listing claim.
What comes in the package bullet?
One grinder, one wheel guard, one grinding wheel, one cutting guard, one auxiliary handle, one wrench, and a manual.
The Kistrba ZGWL1640BDWTUK is an 18 V bare body at about £38.95, listed at 200 W, up to 10,000 rpm, and 1.53 kg, and the highlight calls it 5 inch, which this comparison treats as 125 mm. The title says no battery, and a bullet lists DeWalt 18 V and 20 V Max pack codes and tips 4.0 Ah or higher. It is not a DeWalt tool. The star line is 4.0 from 32 reviews. UK buyers who already owned those packs cut rebar, and one said a 4 Ah pack lasted better than a 2 Ah pack. The same sample includes a wobbling cutting disc, rough final-drive gearing that led to a return, and a trigger that starts the tool on a touch even though a bullet describes a paddle switch. A printed 200 W is far below the corded tools here, so it is not equivalent cutting power. Buy it only as a body for a pack you already own, and stop if the disc runs out of true.
Pros
Cons
Best for: Short cuts on a DeWalt pack you already own, preferably 4.0 Ah or higher as the seller tips.
Less suitable: A first cordless kit, or any job where the disc must run true.
Specifications
Common questions
Does the Kistrba price include a battery?
No. The title says no battery. A bullet lists DeWalt 18 V and 20 V Max pack codes and tips 4.0 Ah or higher. It is not a DeWalt tool.
What wattage and voltage are printed?
The technical lines say 200 W, 18 V, and 10,000 rpm. Item weight is 1.53 kg. The highlight calls it a 5 inch grinder.
Is a second switch action stated?
A bullet describes a paddle switch and power-off protection. A review says there is no double trigger and the tool starts when the main trigger is touched.
The YWNYT PPL26011301 is a 125 mm bare body at about £45.99, with bullets stating up to 8,500 rpm, an M14 spindle, and an item weight of 2.84 kg. No wattage or voltage row is printed, and the title says no battery while naming DeWalt 18 V and 20 V pack codes. It is not a DeWalt tool. The amazon.co.uk line is 3.0 from two reviews. The only saved review text is marked Reviewed in Germany, so it is not UK opinion and is not used as one. The included-components line says a cordless angle grinder with accessories, without listing a guard or a disc count. At about £45.99 it costs more than several complete corded grinders in this set and still needs a battery. Leave it unless you already own a listed pack and can return a body that has no usable UK review text.
Pros
Cons
Best for: Only a spare body if a listed pack is already on the shelf and you can return it.
Less suitable: Anyone choosing a first grinder from UK review text.
Specifications
Common questions
Is a battery included?
No. The title says no battery. A bullet names DeWalt 18 V and 20 V pack codes and says the tool does not include a battery.
What size and speed are printed?
Bullets state 125 mm, up to 8,500 rpm, and an M14 spindle. Item weight is 2.84 kg. No wattage row is printed.
Can the German review be used as a UK opinion?
No. The only review block is marked Reviewed in Germany. The star line is still the amazon.co.uk aggregate of 3.0 from 2.
The SnowVolt listing is a 125 mm brushless bare body at about £26.99, with a claim of up to 10,000 rpm, three speed settings, and an item weight of 1.2 kg. The title says no battery, and a bullet names DeWalt 20 V Max pack codes. It is not a DeWalt tool. The star line is 2.0 from one review, and that UK review says the rpm does not match the product page and that changing speed does not work. The box lists a handle, a wrench, a protective cover, and one grinding disc. There is no wattage row. A bullet also claims low-voltage and over-current cut-off, which this single review does not confirm. A body at about £26.99 only looks cheaper than a corded grinder near £30 if you already own a pack the seller names.
Pros
Cons
Best for: Only a returnable trial if you already own a DeWalt pack the seller lists.
Less suitable: A first grinder, or anyone without that battery.
Specifications
Common questions
Is a DeWalt battery in the box?
No. The title says no battery. A bullet names DeWalt 20 V Max pack codes and says the battery is not included. This is not a DeWalt product.
What disc and speeds are stated?
The title says 125 mm and brushless. Bullets say up to 10,000 rpm and three speed settings. Item weight is 1.2 kg.
How many reviews does the listing show?
The listing line is 2.0 from 1 review. That review says the speed change does not work.
Twelve amazon.co.uk listings were scored from the stored pages and the review notes already on file. Shelf date 20 October 2026. There is no laboratory test. Stars are the listing line.

15%GBP on 20 October 2026 against what you can use on day one. The dearest corded tool does not lose the top score when the review record is the strongest. The cheapest tool does not take best value if the switch and the plug line are weak.
Buy the disc class, the lead, and the box before you buy a star line. UK mains are nominally 230 V. A bare body is not a complete kit. A wood saw blade in a carton is not approval to cut wood. A UK review sample is not the same thing as a star line whose only saved text is from Germany.
An angle grinder is a handheld tool whose spindle sits at roughly a right angle to the motor. On the small classes here, discs are 115 mm (about 4.5 inch) or 125 mm (about 5 inch). A 230 mm grinder is a different tool. Small machines use an M14 spindle. Bores are printed as 22.2 mm or 22 mm, and a common bore is also given as 22.23 mm. Screwfix puts cutting depth at about 30 mm on 115 mm and about 38 mm on 125 mm, against about 70 mm on a 230 mm disc.
OPSS alert PSA5 says not to fit a toothed saw blade or a chainsaw disc. A wood blade listed in a bullet is not approval to cut wood. Screwfix does not recommend cutting wood with an angle grinder.
SnowVolt, Kistrba, and YWNYT name DeWalt pack codes and do not include a battery. None of them is a DeWalt tool. The only kit here with a battery and a charger is the DCA ADSM06-125.
DEKOPRO is the lowest shelf price, at about £25.99, with heat, an intermittent switch, and a 220 V line that does not confirm the plug. A stiff or failed switch is also the repeated theme on the CHANTPOWER and POSENPRO listings.
Small grinders in this set are 115 mm or 125 mm, on an M14 spindle. Bores are printed as 22.2 mm or 22 mm. Screwfix puts cutting depth at about 30 mm on 115 mm and about 38 mm on 125 mm, and about 70 mm on 230 mm. None of these listings is a 230 mm tool. A household watt band on that guide is about 500–900 W for 115 mm and about 700–1,200 W for regular small-scale 125 mm work. No-load rpm is not the speed in the cut.
Beside a socket, use a corded tool. Away from a socket, use a kit that includes a battery and a charger, or a bare body only if you already own a listed pack. Three bare bodies name DeWalt codes and are not DeWalt tools. Reviews of the DCA kit put runtime near 20–30 minutes. UK mains are nominally 230 V. Electrical Safety First says the tool or its charger needs a UK 3-pin plug and fuse. Printed voltages here are 230 V, 240 V, and 220 V, and no row confirms BS 1363.
Three typical situations, each with a recommendation from this comparison.
You already own 115 mm discs and you want a light corded body. The Bosch Professional GWS 7-115 is the top pick at about £67.55: 720 W, 1.9 kg, 240 V, and 4.6 from 1,378 reviews. No disc is in the box, and the housing runs hot after about 10–15 minutes.
You want guards, discs, and a pin spanner in the carton. The DCA ASM18-115 is best value at about £29.99: 860 W, 1.67 kg, six discs, and 4.3 from 74 reviews. The guard is fiddly, and a novice reviewer called the supplied discs poor.
You do not already own a battery platform. The DCA ADSM06-125 kit is about £56.98 with a 4.0 Ah battery, a 2 A charger, and 4.3 from 87 reviews. UK reviews put runtime near 20–30 minutes, not a manual claim near 120 minutes.
The top pick is the Bosch Professional GWS 7-115 at about £67.55: 720 W, 115 mm, 1.9 kg, 240 V, a guard and a two-hole spanner, and 4.6 from 1,378 reviews. No disc is in the box, and the housing runs hot after about 10–15 minutes. Best value is the DCA ASM18-115 at about £29.99, not the cheaper DEKOPRO. The DCA lists 860 W, 1.67 kg, six discs, two guards, and a pin spanner, at 4.3 from 74 reviews. Review themes are a fiddly guard and poor supplied discs, not a failed switch. DEWINNER has more reviews at a similar price and does not take best value, because more than one UK review says the locking spanner was missing. None of these scores is a laboratory test.
DCA ASM18-115
About £29.99 for 860 W, 1.67 kg, six discs, two guards, and a pin spanner, at 4.3 from 74 reviews.
