The best Bosch Professional angle grinders, compared.
Top pick: Bosch GWX18V-11PS Best value: Bosch GWS 9-115 S 230 V – The same 88 points from a smaller sample of 205 ratings. Speed selection on a 230 V listing that agrees with itself, 900 W, 1.66 kg, about £77.00. Updated October 2026.
An angle grinder is a handheld power tool that spins a bonded disc to cut or grind metal, masonry, paving and tile. A professional angle grinder in the small class is a corded lead or an 18 V body sold without a pack or a charger. In the UK you buy one for a house socket, for a site transformer, or because the packs are already on the shelf. You recognise a suitable listing by the disc it prints, by the guard and the nut in the box, and by a style line and a voltage field that name the same supply. A speed dial counts only when the bullets say so. A two-hole spanner, a quick-locking nut and a click-on spindle are different disc changes. No cutting disc belongs in the plan until the scope line names one. At work, the guard should stop an oversize wheel, and the speed must not exceed the mark on the wheel. Eye protection is discussed against BS EN 166. Use both hands, and keep the guard on.

Question 1 of 2
What supply will you use?
The GWX18V-11PS at about £199.98 is the paddle-switch body with an L-BOXX, part 06019N4400, and the bullets name kickback control and an intelligent brake. The star line is 4.9 from 13 amazon.co.uk ratings. The seven review bodies in the file are from Germany, France and Italy, with none from the United Kingdom, so the score is 65 after a six-point deduction. Those reviews call a click disc change practical and warn that the discs are X-LOCK, including a German note that older discs need an adapter. The bullets themselves do not print X-LOCK, so that fitting claim comes from non-UK reviews rather than the feature list. Included components are the tool and one L-BOXX, and the scope line adds a Vibration Control handle, a guard and a protective cover. No battery is named. The 4.4 kg figure is the item weight on the listing and is not split between the tool and the case. This listing is not order 0 601 9N4 200.
Pros
Cons
Best for: You already own compatible click-on discs and Bosch Professional packs, and you want the brake and paddle the bullets name.
Less suitable: A nut-type disc collection, a first battery kit, or a choice based only on 4.9 from 13 ratings.
Specifications
Common questions
Does the listing include a battery?
No. Included components are the GWX18V-11PS and one L-BOXX. The scope line adds a Vibration Control handle, a guard and a protective cover.
Why is the weight 4.4 kg?
That is the item weight on the listing. The file does not split tool weight from the case.
Do the bullets say X-LOCK?
No. They say kickback, an intelligent brake and a paddle switch. Non-UK reviews are the lines that say X-LOCK. This listing is not order 0 601 9N4 200.
The named GWS 18V-8, part 06019N9000, is the bare 18 V body at about £89.44 with 4.7 from 531 amazon.co.uk ratings. Of 50 reviews read, 35 are from the United Kingdom. They describe a lighter tool than an older Bosch 18 V grinder, enough for short cuts such as nails, and quiet enough that more than one reviewer mentions it. A latching switch was used for a bullnose on a porcelain slab. The style is without battery or charger, and the scope line is a flange, locking nut, two-hole spanner, auxiliary handle and guard 1 605 510 365. There is no quick-release nut. Reviewers say a small pack is eaten on longer work. The specification table does not print a disc diameter, and the reviews disagree between 115 mm, 125 mm and a warning about a 100 mm import. That price is the body only.
Pros
Cons
Best for: Short cuts when Bosch Professional 18 V packs and a charger are already on the shelf.
Less suitable: A first kit with no packs, or a job that needs 125 mm printed on the listing.
Specifications
Common questions
Does it come with a battery?
No. The style is without battery or charger. The scope line is flange, nut, spanner, auxiliary handle and guard.
What disc size is printed?
The specification table does not print a diameter. UK reviews mention 115 mm, 125 mm and, in one warning, a 100 mm import. The listing is not settled as either 115 mm or 125 mm.
Which batteries do reviewers name?
UK reviews say it suits people who already own Bosch 18 V packs. The listing does not name ProCORE or GBA in the bullets.
Part 06019N9004 is a bare 18 V body at about £89.99, listed at 800 W and 1.24 kg, with the same 4.7 from 531 as the GWS 18V-8 row. The amazon title does not print GWS 18V-8. The 50 reviews read in the file are a near-copy of that other listing, so they are weak evidence of a separate UK sample. The praise that does appear is the same light body for short cuts, quiet running, and a latching switch. There is no battery or charger, and no quick-release nut. The scope line uses protective guard 1 605 510 364, while the named GWS 18V-8 uses 1 605 510 365. Disc diameter is not in the table, and the copied reviews still disagree between 115 mm, 125 mm and a 100 mm import warning. The score is 81 after a six-point deduction for that copied review text.
Pros
Cons
Best for: You have already confirmed part 06019N9004 and you own Bosch Professional 18 V packs for short cuts.
Less suitable: Anyone treating the 531 ratings as a separate test of this guard, or anyone who needs 125 mm printed on the page.
Specifications
Common questions
Is the model name GWS 18V-8?
The amazon title does not say so. The model number is 06019N9004. The bullets and review text closely match the GWS 18V-8 listing.
Does it include a battery?
No. The style is without battery or charger.
How does the guard part differ?
This scope line uses protective guard 1 605 510 364. The GWS 18V-8 listing uses 1 605 510 365.
Part 06019N4000 is the cordless body whose bullets say a 6-speed dial, listed at about £148.99 with 4.7 from 176 amazon.co.uk ratings. The title says Small Angle Grinders and does not print GWS 18V-11, though UK review titles use GWS 18V-11 S and 125 mm. The scope line is a guard, a quick-locking nut, a flange and a Vibration Control handle, and the style is without battery or charger. Of 50 reviews read, seven are from the United Kingdom, and those titles praise power and balance. German reviews praise the dial and a fast disc change. One UK review puts extra batteries at about £50 to £80, which is that reviewer's range rather than a live pack price. A German review says a normal pack can cut out under load when it is not full, and prefers ProCORE. The horsepower field prints 1100 Horsepower, which is not a usable figure beside the 1,100 W bullet, and voltage is absent from the table. The 18V-11 manual states 3,000 to 9,000 rpm on the S and KickBack Control. That range is not in the amazon table.
Pros
Cons
Best for: You already own Bosch Professional packs, preferably ProCORE, and you want the dial the bullets name.
Less suitable: A first 18 V kit, or a buyer who assumes part 06019N4100 has the same dial because the photos look alike.
Specifications
Common questions
Does the amazon title say GWS 18V-11 S?
No. The title says Small Angle Grinders. UK review titles use GWS 18V-11 S and 125 mm. The model number is 06019N4000. The title does not print the disc diameter.
Is there a speed dial?
The bullets say easy 6-speed selection on a dial wheel. No revolutions range is printed. The 18V-11 manual states 3,000 to 9,000 rpm for the S.
Is a battery included?
No. The style is without battery or charger. The scope line is guard, quick-locking nut, flange and a Vibration Control handle.
The 240 V GWS 7-115 is the busy corded row in this set, at about £67.55 with 4.6 from 1,378 amazon.co.uk ratings, and the file holds 50 UK reviews. Reviewers use the 720 W, 11,000 rpm, 1.9 kg body on studs, plaster, brick and paving, and several mention a smooth start plus a guard that can sit on either side. One long-term user reports brushes only after about seven years. The scope line names an auxiliary handle, flange, locking nut, guard and a two-hole spanner, and it does not name a cutting disc. UK reviews say the photo's anti-vibration handle arrived as a plain plastic one, and that the lead is stiff and kinked out of the box. The housing is too hot to hold after about 10 to 15 minutes, and more than one unit produced a burning smell. A motor that stopped after light use, came back from repair as no fault found, and then failed again is in the file as well. It is the top pick because it ties on points with the 230 V GWS 9-115 S and has the larger review sample.
Pros
Cons
Best for: A UK house socket and short 115 mm jobs, when you want the longest review sample in this set.
Less suitable: Polishing or a wire brush that needs a slower speed, or a 110 V site lead.
Specifications
Common questions
Is a disc included?
No. The scope line names a handle, flange, locking nut, guard and two-hole spanner. UK reviews say there is no cutting disc.
Is this 110 V?
The style is 240V and the voltage field is 240 volts. The scope line also says voltage 240 V.
Does the listing state variable speed?
No. The specification table prints 11,000 rpm and does not mention a speed dial.
This is the GWS 18V-8 whose title states 125 mm and an L-BOXX, part 06019N9001, at about £131.06. The listing is 4.6 from 241 amazon.co.uk ratings, 800 W and 1.22 kg, and the style is an L-BOXX without battery or charger. Included components are the tool and the case, not a guard, a handle or a disc. Of 50 reviews read, two are from the United Kingdom, and both call it a useful kit that feels more versatile than an old corded grinder. A Netherlands review says a Gardena-Bosch universal 18 V pack does not fit and that Bosch Professional packs do. The listing itself does not print that warning. You are paying more than the bare GWS 18V-8 at about £89.44 for a printed 125 mm line and a case, still without a battery.
Pros
Cons
Best for: You want 125 mm printed on the amazon title and an L-BOXX, and you already own Bosch Professional 18 V packs.
Less suitable: A green or Gardena-style 18 V pack, or a buyer who thinks the case means the battery is inside it.
Specifications
Common questions
What disc size does the title state?
125 mm. The specification table does not add a separate diameter row.
Is a battery included?
No. The style is an L-BOXX without battery or charger. Included components are the GWS 18V-8 and an L-BOXX.
Will any Bosch 18 V pack fit?
A Netherlands review says a Gardena-Bosch universal 18 V pack does not, and that Bosch Professional packs do. The listing itself does not print that warning.
The 230 V GWS 9-115 S is the speed-selection house tool in this set, listed at about £77.00 with 4.6 from 205 amazon.co.uk ratings. Style and the voltage field both say 230 V, part 0601396171, at 900 W and 1.66 kg. UK reviewers use the dial for flap wheels, wire brushes, polishing and porcelain, and they describe a light, narrow body that stays comfortable upside down. Several mention a soft ramp-up and a guard that adjusts quickly and stays put. One review covers hours of repointing without a reported fault. The same file says 900 W feels less torquey than a 1,200 W grinder it replaced, and that one unit burnt out after light work and overheated. A thin concrete-slab cut wore a disc out, the next disc stuck, and that motor burnt out too. No cutting disc is in the scope line. It is best value because it matches the top score and the larger sample sits on the 240 V GWS 7-115.
Pros
Cons
Best for: House-socket work where a flap wheel, wire brush or porcelain wants a slower disc than a fixed 11,000 rpm GWS 7-115.
Less suitable: A 110 V transformer lead, or heavy cutting where you already know you want more than 900 W.
Specifications
Common questions
Does it have speed selection?
Yes. The bullets say speed selection. The specification table does not print a revolutions range.
What voltage is the style?
Style and voltage field both say 230 V. Part number 0601396171.
Is a disc in the box?
No disc is named. The scope line is flange, carton, guard, nut, auxiliary handle and two-hole spanners.
Part 06019N4100 is the 1,100 W bare body at about £135.95 whose bullets do not mention a speed dial, with 4.6 from 93 amazon.co.uk ratings. The title does not print GWS 18V-11. UK reviews call it powerful, comfortable and well made, and they say the anti-vibration handle is in the box. The scope line is a guard, a quick-locking nut, a flange and a Vibration Control handle, with no battery. A German review says the machine has no speed control while the photos and description look like the S model. Only 10 of 45 review bodies in the file are from the United Kingdom. The horsepower field prints 1100 Horsepower, and disc diameter and voltage are both absent from the table. At about £13 less than part 06019N4000, the saving is the dial you are not being promised. The 18V-11 manual states 9,000 rpm for the plain body. Do not give this listing a speed dial.
Pros
Cons
Best for: You want the quick nut and the damped handle, and you have checked that a dial is not in these bullets.
Less suitable: Flap wheels or polishing that need the 6-speed dial stated on part 06019N4000.
Specifications
Common questions
Does this listing state a speed dial?
No. The bullets do not mention a dial. A German review says there is no speed control and that the photos look like the S model.
What is the part number?
06019N4100. The amazon title does not print GWS 18V-11. UK reviews use that name. The 18V-11 manual states 9,000 rpm for the plain body.
Is a battery in the box?
No. The style is without battery or charger.
This GWS 9-115 S is the corded row where style and the voltage field both say 110 V, part 0601396161, at about £79.99. The listing is 900 W and 1.75 kg, with speed selection in the bullets and no revolutions figure printed. Only 22 amazon.co.uk ratings sit behind the 4.4 line, and the file holds five UK review texts. Those texts call it powerful and robust, and one reviewer finds the adjustable speed useful. The same small file says the box arrived ripped with the auxiliary handle missing. It also records two failures inside a year, the first after eight months and the replacement after two months. The included-components field says only x, while the scope line still names a flange, carton, guard, nut, auxiliary handle and spanners, and no disc. The 22-rating sample sits in the lowest sample band, which is why the score is 72.
Pros
Cons
Best for: A site transformer, when you want speed selection and both voltage fields already say 110 V.
Less suitable: A house socket, or a buyer who wants a large UK review sample before trusting a 110 V tool.
Specifications
Common questions
Is this the 110 V GWS 9-115 S?
Style is 110 V and the voltage field is 110 volts. Part number 0601396161. Both fields agree, unlike the cheaper GWS 7-115 listing.
Does it have speed selection?
The bullets say speed selection. No revolutions figure is printed.
What is in the included-components field?
That field says only x. The scope line still names flange, carton, guard, nut, auxiliary handle and spanners.
Across 238 amazon.co.uk ratings, the GWS 7-115 at about £65.00 holds 4.2, and the 30 UK reviews in the file are mostly from people who already expected a site tool. Style is 110V and the scope line says voltage 110 V, while the voltage field says 230 volts, so the listing does not tell you which socket it belongs on. Reviewers who ran it at work describe a slimmer body than an older green 240 V Bosch, and they used it on metal, stone and tile. Several were surprised by a yellow industrial plug and say a house socket needs a transformer. One review calls it a 110 V product that should not be sold for 240 V UK sockets. Fault notes include a motor that smoked on first plug-in, flames and a scorched cable after about half an hour, and a welder who wore the brushes out on two tools in a year. No cutting disc is in the scope line, and the side handle is not named there either. The score is 77 after an eight-point deduction for the voltage clash. Do not treat it as settled at 110 V or at 230 V.
Pros
Cons
Best for: You already have a 110 V site transformer and you will check the plug on the unit you receive before you treat either voltage field as settled.
Less suitable: A house 13 A socket, or any buy where the listing has to agree with itself before you plug it in.
Specifications
Common questions
Is it 110 V or 230 V?
The style is 110V and the scope line says voltage 110 V. The voltage field says 230 volts. UK reviews mention a yellow industrial plug and a transformer. The listing is not settled as either supply.
Is a disc included?
No disc is named in the scope line. The line lists a flange, a nut, a guard and two spanners.
Does the listing state a speed?
No. There is no revolutions field and no speed-selection bullet.
Ten amazon.co.uk listings were scored from the stored pages and the review notes already on file. Shelf date 19 October 2026. There is no laboratory test. Stars are the listing line, not a workshop trial. The four parts total 91 points before deductions: stars 40, sample size 20, fit 22 and price band 9. The weights below are those shares scaled to 100. Deductions sit outside the weights: minus 8 when the style and the voltage field disagree, minus 6 when the review text is a near-copy of another listing in this set, and minus 6 when the file has no United Kingdom review body. The highest total is the top pick. If two totals match, the larger amazon.co.uk review count takes it. Best value is the next-highest total. One of each. A bare-tool price is not the cost of batteries.
Stars
44%Points are (amazon rating / 5) times 40, rounded to the nearest whole number. A 4.9 line is 39 points, 4.7 is 38, 4.6 is 37, 4.4 is 35 and 4.2 is 34. The weight 44 is that 40-point part as a share of 100.
Review sample
22%200 or more ratings score 20. From 50 to 199 scores 10. From 10 to 49 scores 6. In this set, 176 and 93 ratings score 10, and 22 and 13 score 6. The weight 22 is that 20-point part as a share of 100.
Category fit
24%Each row scores 22 because each file is a Bosch Professional angle grinder in this set. Fit does not add points for a dial, a brake or a case. The weight 24 is that 22-point part as a share of 100.
Price band
10%Under £80 scores 9. Under £120 scores 7. Under £160 scores 5. £160 and above scores 4. The weight 10 is that 9-point part as a share of 100. A bare-tool price is not the cost of a battery.
Separate these bodies by supply, by the disc the page prints, and by the part number. A bare price is the tool only. A photograph is not a speed dial, and a star line is not a laboratory test.
A Bosch Professional angle grinder in this set is a small blue body, either a corded lead or an 18 V tool. No cordless listing includes a ProCORE or GBA pack or a charger. You already own those packs, or you want a 230 V or 240 V lead for a house socket, or a 110 V tool for a site transformer. There is no 230 mm grinder in this comparison. Shelf prices on 19 October 2026 run from about £65.00 to about £199.98.
No cordless listing includes a ProCORE or GBA pack or a charger. An L-BOXX is a case. It is not a battery. One UK review puts packs at about £50 to £80. That range is not the tool price.
Part 06019N4000 states a 6-speed dial. Part 06019N4100 does not, and a German review says the photos look like the S model. On a GWS 7-115, UK reviews say the photo's anti-vibration handle arrived as a plain plastic one.
The cheaper GWS 7-115 is style 110V while the voltage field says 230 volts. Leave it open. Non-UK reviews of the GWX say conventional discs need an adapter. The bullets on that listing do not print X-LOCK.
UK mains are nominally 230 V, and a house plug is BS 1363. In this set, 240 V and 230 V are the house-socket rows where the listing agrees with itself. 110 V is for a site transformer. HSE ranks battery tools first in harsh places, then 110 V centre-tapped. The IET describes about 55 V to earth as good practice, not a duty by itself. A yellow industrial plug in the reviews is a site plug, not a 13 A moulded plug.
Match the disc to the diameter the page prints. 115 mm is stated on the GWS 7-115 and the GWS 9-115 S. 125 mm is stated on one title only. Two 800 W tables omit it, and the reviews conflict. Do not fill those cells from a brand page or from a copied review. A quick-locking nut, a two-hole spanner and a click spindle are three different changes. The GWX bullets do not say X-LOCK. Non-UK reviews do. Read the part number against the bullets. 06019N4000 has the 6-speed dial. 06019N4100 does not.
Three typical situations, each with a recommendation from this comparison.
You want a 115 mm corded body on a 13 A socket. The 240 V GWS 7-115 is the top pick at about £67.55, with 720 W, 11,000 rpm and 4.6 from 1,378 ratings. Style, voltage and the scope line agree. No cutting disc is in the box. For a flap wheel or a wire brush, the 230 V GWS 9-115 S adds speed selection at about £77.00.
You already have a site transformer. The GWS 9-115 S at about £79.99 is the row where style and the voltage field both say 110 V, with speed selection, 900 W and 4.4 from 22 ratings. The cheaper GWS 7-115 at about £65.00 is style 110V while the voltage field says 230 volts. Leave that clash open and check the plug.
No cordless listing includes a pack or a charger. The bare GWS 18V-8 is about £89.44, 800 W and 1.22 kg, with 4.7 from 531 ratings, for short cuts. The diameter is not in the table. Part 06019N4000, about £148.99, is the body whose bullets state a 6-speed dial. Part 06019N4100 does not.
The top pick is the 240 V GWS 7-115 at about £67.55. It scores 88, the same as the 230 V GWS 9-115 S, and 1,378 amazon.co.uk ratings take the top pick over 205. Style, the voltage field and the scope line all say 240 V. It is 720 W, 11,000 rpm and 1.9 kg, with no cutting disc in the box. Best value is the 230 V GWS 9-115 S at about £77.00, also 88, when a flap wheel, wire brush or porcelain wants speed selection. The bare GWS 18V-8 at about £89.44 is the next score, and that price is the body only. None of these scores is a laboratory test.
Bosch GWS 9-115 S 230 V
The same 88 points from a smaller sample of 205 ratings. Speed selection on a 230 V listing that agrees with itself, 900 W, 1.66 kg, about £77.00.
