The best Bosch 230 mm angle grinders, compared.
Top pick: Bosch GWS 2200 P 110 V Best value: Bosch GWS 22-230 J – About £115.81 for 2,200 W, soft start and an anti-vibration handle, 4.8 from 183 ratings. The 120 V cell is unverified. Updated October 2026.
A 230 mm angle grinder is a corded two-handed tool for a 230 mm disc. In the UK you use one to cut stone, concrete or metal with more reach than a 115 mm or 125 mm grinder. Expect 5.3 to 5.5 kg, an M14 spindle and a bore of about 22.2 mm. The disc must be marked for at least the no-load speed, often 6,500 rpm. The carton holds a guard, flanges, a nut, a spanner and a side handle, not a disc or a case. A 13 A socket wants 230 V and a BS 1363 plug. A site supply is 110 V. Do not swap those plugs. One switch limits the starting current and will not restart after a power cut. The other stops the motor when you let go and starts harder. Keep the guard on and run the tool unloaded for at least a minute. At work, PUWER 1998 and HSG17 cover the guard and training. Concrete dust needs extraction and respiratory protection. If the plate and the socket disagree, ask a competent person.

Question 1 of 2
Where will you plug it in?
The Bosch GWS 2200 P on this listing is the 110 V, 2,200 W site grinder for a 230 mm disc, listed at about £153.60, and the title is the only row here that states 110 V. The amazon.co.uk line is 5.0 from one review, and the only written text is the word Good, so that star is not a pattern you can lean on. The listing says the PROtection switch stops when you release it, and it names the GDE 230 FC-S as compatible rather than included. The carton is the grinder, an auxiliary handle, guard, two-hole spanner, backing flange, locking nut and cardboard, with no disc. The weight cell prints 1.62 kg, which conflicts with Bosch UK's 5.3 kg for order number 06018F4160, so you should not use 1.62 kg as the tool's mass. There is no no-load speed and no warranty months on this raw file. It belongs on a 110 V site supply, and it is the wrong tool for a UK 13 A socket.
Pros
Cons
Best for: You already have a 110 V site supply and you need a 230 mm Bosch that stops when you let go.
Less suitable: You have a household 13 A socket, or you want a review file you can actually read.
Specifications
Common questions
Is this the 110 V model?
Yes. The amazon.co.uk title states 110 V, a 230 mm disc and a 2,200 W motor.
Does the box include a disc?
No. The included items are the grinder, a cardboard box, auxiliary handle, guard, two-hole spanner, backing flange and locking nut.
What do reviewers say?
There is one written review, and the text is Good. The listing shows 5.0 from 1 review.
The Bosch GWS 22-230 J is the 2,200 W corded grinder in this amazon.co.uk set, listed at about £115.81 with 4.8 from 183 reviews, and reviewers describe cutting stone, concrete and paving with a soft start that does not trip a 16 A fuse. The spec table prints 120 V, and the sampled reviews do not confirm the plug, so you should read the rating plate before you treat it as a house-socket tool. The box is the grinder, an anti-vibration side handle, flange, locking nut, guard, two-hole spanner and a carton, with no disc. Reviewers call the head steady and mention three side-handle positions, and one says the guard can cover the disc when the tool is set down. The same file calls it heavy at about 5 kg, which matches the listed 5.3 kg, and one buyer received a dead unit, then a replacement with a scratch on the housing. Most of the long reviews are German, Spanish, Italian or Swedish, so the star line is an amazon.co.uk aggregate, not a British-only sample. In this comparison it is the best value when you want 2,200 W, soft start and restart protection at the lowest price here, and a poor match if you need 230 V already printed on the listing or a disc in the carton.
Pros
Cons
Best for: You want 2,200 W and soft start for a 230 mm disc, and you will check the rating plate against your socket.
Less suitable: You need 230 V already printed on the amazon.co.uk row, or a disc in the box.
Specifications
Common questions
Is the GWS 22-230 J cordless?
No. The amazon.co.uk listing gives the power source as AC/DC and the box is a corded carton kit with no battery.
Does it come with a cutting disc?
No. The scope is the grinder, an anti-vibration handle, flange, locking nut, guard, two-hole spanner and a carton. Reviews say the disc is bought separately.
What voltage does the listing state?
The spec table says 120 volts. The stored reviews do not include a UK review that confirms the plug, so the cell is left as printed.
The Bosch GWS 20-230 J is the 2,000 W, 230 V grinder in this set, listed at about £145.00 with 4.7 from 149 reviews, and reviewers describe cutting paving in one pass and granite over years with a soft start. The listing prints 6,500 rpm, a 5.3 kg weight and an aluminium housing, and the switch line is soft start plus restart protection. The box is the grinder, spanner, clamp flange, clamping nut, guard, auxiliary handle and cardboard, with no disc. A granite user reported carbon brushes at about half wear after three years, and another review mentions a GDE 230 FC-S dust guard that is not in the carton. The same file says the housing gets very hot after hours at full load, the guard screw can seize unless it is greased, and one unit failed after a single cut and was repaired. Long reviews are mostly not written in the UK, so the star line is the amazon.co.uk aggregate. In this comparison it is the top pick when you want soft start and restart protection on a listing that already says 230 V, and a weaker match if you wanted 2,200 W at the lower price or a disc included.
Pros
Cons
Best for: You want 230 V already printed, with soft start, for paving or metal on a 13 A supply.
Less suitable: You want the cheaper 2,200 W J model, or a switch that stops the moment you let go.

Common questions
Is the GWS 20-230 J cordless?
No. The listing says corded electric, 230 volts and 2,000 watts.
Does it include a disc?
No. The pack is the grinder, spanner, clamp flange, clamping nut, guard, auxiliary handle and cardboard.
What voltage is printed?
230 volts, with a no-load speed of 6,500 rpm and a listed weight of 5.3 kg.
The Bosch GWS 20-230 P is the 2,000 W grinder with a PROtection switch, listed at about £129.00, the same figure Bosch UK prints for order number 06018C1171, with 4.4 from 8 ratings and only three written reviews in the stored file. The listing says the switch turns off when you release it, and it does not state a voltage or a no-load speed. Bosch UK lists that order number at 230 V, 6,500 rpm and 5.5 kg. The carton holds the grinder, a standard auxiliary handle, guard, backing flange, locking nut, two-hole spanner and cardboard, and not a disc or a case. One UK line says it does the job, a French review calls it powerful, and that review notes it shipped from the UK, so the plug was a UK plug, which was a problem for a buyer in France. There is no repeated defect in those three texts, and eight ratings are too few to show how the motor lasts. The listed weight is 5.5 kg and the warranty cell says 24 months. It suits you if you want the motor to stop when you let go and you will confirm the plate yourself, and it is a weak choice if you wanted soft start or a voltage already printed on the page.
Pros
Cons
Best for: You want a 2,000 W tool that stops when you release the switch, and you will read the rating plate.
Less suitable: You want soft start on a 13 A fuse, or a review file large enough to judge wear.
Specifications
Common questions
Is the GWS 20-230 P cordless?
No. The listing power source is AC/DC and the pack is a corded tool in a cardboard box.
Does the box include a disc or a case?
No. You get the grinder, a standard auxiliary handle, guard, backing flange, locking nut, two-hole spanner and a cardboard box.
What mains voltage is printed?
This amazon listing does not state a voltage. It says AC/DC, 2,000 W and 5.5 kg. Bosch UK lists order number 06018C1171 at 230 V.
The Bosch GWS 22-230 P is the 2,200 W grinder with a PROtection switch, listed at about £156.07 with 4.3 from 26 reviews, and a UK verified review of 10 April 2023 says it cuts concrete easily and feels sturdy. That same review says there is no soft start and the tool kicks when you switch it on, and that the tool arrived as 230 V with a UK 3-pin plug. The spec table still prints 120 V, so the cell and the UK review disagree and you should trust the rating plate on the tool you receive. The box includes a vibration-control side handle, guard, flange, locking nut, two-hole spanner and a carton, and the UK reviewer wanted a case that is not there. Listed weight is 5.5 kg and the warranty cell says 24 months. French and Spanish buyers object to a British or American plug, which is a complaint from outside the UK rather than a fault in a BS 1363 plug. It is the one to consider when you want 2,200 W and a switch that stops as you let go, and you can accept a hard start.
Pros
Cons
Best for: You want 2,200 W that stops when you release the switch, and you can handle a hard start.
Less suitable: You want soft start on a 13 A circuit, or you are buying from the 120 V cell alone.
Specifications
Common questions
Is the GWS 22-230 P cordless?
No. The listing power source is AC/DC and the pack is a corded tool in a cardboard box.
Does it have soft start?
A UK review says there is no soft start and that the tool kicks when you switch it on. The listing itself only names the PROtection switch.
Why does the table say 120 V?
The spec table prints 120 volts. A UK verified review says the tool is 230 V with a UK 3-pin plug and that the 120 V line is wrong.
Five amazon.co.uk listings were scored from the stored pages, the review notes on file, and the Bosch UK pages for the matching order numbers. Shelf date 20 October 2026. This is not a laboratory cut. A star average is the listing line. Long reviews on the two J listings are mostly written outside the UK, so that average is kept and reduced. The highest score is the top pick. The lowest price with 2,200 W and soft start, on a different listing, is the best value, and the 120 V caveat stays in the text. One of each. The weights below sum to 100.
Amazon UK evidence
40%Star rating and review count on amazon.co.uk. One review, or a file of eight ratings, cannot fill this block. A large aggregate whose long texts are not British is kept and reduced.
Stated specification
30%Watts, a voltage that does not fight the title, a named switch, and a weight you can use. A 120 V cell that a UK review disputes, or a 1.62 kg cell that fights Bosch UK's 5.3 kg, is a deduction. This block does not invent a plug.
Review outcome
20%Notes that describe a real cut, a soft start, or a kick score higher than a file whose only text is Good.
Value
10%Shelf price in GBP against watts and the switch you can name. Used so best value can sit on a different listing from the top score. The lowest price does not win the top score as well when the voltage cell is unverified.
Read the rating plate and the switch family before you read a star line. A 230 mm disc, an M14 spindle and a bore of about 22.2 mm are the stable checks. UK mains and a 110 V site supply are different plugs. None of these five cartons includes a disc. A star line whose long texts are not from the UK is a listing aggregate, not a British sample.
A 230 mm angle grinder is a corded Bosch Professional tool for a 230 mm disc, not a 115 mm or 125 mm grinder. UK buyers use one to cut stone, concrete or metal with more reach than a small grinder, and they should expect a two-handed tool of about 5.3 to 5.5 kg. The spindle is M14. The bore is about 22.2 mm, and diamond discs are sold as 22.23 mm. No-load speed on the Bosch UK pages and on the J listings is 6,500 rpm. The disc must be marked for at least that speed.
The GWS 22-230 J and GWS 22-230 P tables print 120 V. A UK review of the P model says the tool is 230 V with a UK 3-pin plug. The sampled reviews of the J model do not confirm the plug. Read the plate.
The GWS 2200 P title states 110 V, for a site supply centre-tapped to about 55 V to earth. Changing the plug does not make it a household tool.
The guard stays on. Bosch asks for a no-load run of at least one minute. A grinding disc is not a cutting disc. None of these cartons includes either disc.
Disc and spindle come first. These tools are 230 mm, M14, with a bore of about 22.2 mm. No-load speed on the Bosch UK pages and on the J listings is 6,500 rpm, and the disc must be marked for at least that. Supply voltage is the check that stops a wrong plug. Read the rating plate. Bosch UK lists the GWS 20-230 P and the GWS 22-230 P at 230 V. The GWS 2200 P in this set is 110 V in the title, for a site supply of 102 to 117 V.
Power is 2,000 W on the GWS 20-230 pair and 2,200 W on the GWS 22-230 pair and on the 110 V GWS 2200 P. The extra 200 W does not change the disc size. It does sit next to a vibration-control side handle on the GWS 22-230 P and the GWS 22-230 J. The GWS 20-230 P ships a standard auxiliary handle. The GWS 20-230 J lists an auxiliary handle and does not name it as anti-vibration. What is not in the box matters as much as the watts.
Three typical situations, each with a recommendation from this comparison.
You want soft start on a listing that already prints 230 V. The Bosch GWS 20-230 J is the top pick at about £145.00, with 2,000 W, 6,500 rpm and 4.7 from 149 ratings. No disc is in the box. Housing heat and a seized guard screw show up in the reviews.
The Bosch GWS 2200 P is the 110 V listing at about £153.60, with a PROtection switch and 2,200 W. The only review text is Good. Do not read 1.62 kg as the tool weight. Bosch UK lists 5.3 kg for this order number. Do not run it from a 13 A socket.
The Bosch GWS 22-230 P is about £156.07, 2,200 W, with a vibration-control handle and 4.3 from 26 ratings. A UK review reports concrete cutting, a hard start and a UK 3-pin plug. The table still says 120 V, so read the plate.
The top pick is the Bosch GWS 20-230 J at about £145.00. The listing prints 230 V, 2,000 W, 6,500 rpm, soft start and restart protection, with 4.7 from 149 ratings. The best value is the Bosch GWS 22-230 J at about £115.81: 2,200 W, soft start, an anti-vibration handle and 4.8 from 183 ratings. Its spec table says 120 V, and the sampled reviews do not confirm the plug. The GWS 22-230 P is about £156.07, with a UK review of concrete cutting and a hard start, while the table still says 120 V. The GWS 20-230 P is about £129.00, with eight ratings and no voltage printed on the listing. Bosch UK lists that order number at 230 V. The GWS 2200 P is the 110 V title, about £153.60, with one review that says only Good, and an amazon weight of 1.62 kg that is not the tool weight. None of these scores is a laboratory test, and none of the cartons includes a disc.
Bosch GWS 22-230 J
About £115.81 for 2,200 W, soft start and an anti-vibration handle, 4.8 from 183 ratings. The 120 V cell is unverified.
