For a house socket and the long review sample

For a UK house socket, the top pick in this set is the 240 V GWS 7-115, B01D9QAG9G, at £67.55. Style, voltage field and scope line all say 240 V. The listing prints 720 W, 11,000 rpm and 1.9 kg, and it holds 4.6 from 1,378 ratings. No cutting disc is in the box. Reviewers say the anti-vibration handle in the photo arrived as a plain plastic one, and that the housing is too hot to hold after about 10 to 15 minutes, with a burning smell on more than one unit. If voltage is still open, use the Bosch Professional angle grinder buying guide.

When the job needs a slower disc

The best value row for a house socket, when the work is a flap wheel, a wire brush, polishing or porcelain, is the 230 V GWS 9-115 S, B07HMJGC89, at £77.00. It is 900 W and 1.66 kg, part 0601396171, with 4.6 from 205 ratings. Style and the voltage field both say 230 V, and the bullets say speed selection. The specification table does not print a revolutions range, so you are trusting that bullet. Reviewers say 900 W feels less torquey than a 1,200 W grinder it replaced. One unit burnt out after light work and overheated. No cutting disc is in the scope line. The 110 V twin, B07HM62K7B at £79.99, has the same speed-selection claim and only 4.4 from 22 ratings. Use that twin on a transformer. Use the 230 V row on a normal UK house supply.

If the Professional packs are already on the shelf

If Bosch Professional 18 V packs and a charger are already charged, the cordless default is the named GWS 18V-8, B0DQV9X3BX, at £89.44. It is 4.7 from 531 ratings, 800 W and 1.22 kg, part 06019N9000. Of 50 reviews read, 35 are from the United Kingdom. They describe short cuts such as nails. The style is without battery or charger. There is no quick-release nut, and the table does not print a disc diameter. Reviews disagree between 115 mm, 125 mm and a 100 mm import warning. When the bullets have to say a dial, step up to part 06019N4000, B0DQV82L7J, at £148.99. The bullets name a 6-speed dial, a quick-locking nut and a Vibration Control handle. Part 06019N4100, at £135.95, omits the dial. Pack against lead is the corded or cordless Bosch angle grinder page.

Rows that are easy to misread as the winner

The £65.00 GWS 7-115, B00CA0ZM7Y, is easy to read as the bargain next to the £67.55 240 V tool. Style is 110V and the scope says voltage 110 V, while the voltage field says 230 volts. Reviews mention a yellow industrial plug, smoke, a scorched cable and burn-out on some units. Skip it for a house socket. If you are matching a site transformer, read the 110V Bosch angle grinder page before you treat either field as settled. The GWX18V-11PS, B0G662PLHR, at £199.98, shows 4.9 from 13. The bullets name a paddle switch, kickback control and an intelligent brake, plus an L-BOXX, and they do not name a battery. None of the review bodies in the file is from the United Kingdom, and those reviews talk about X-LOCK discs the bullets do not print. No listing in this set states a cutting disc in the box.

Common questions

Which Bosch Professional grinder has the longest UK review sample?
The 240 V GWS 7-115, B01D9QAG9G, at £67.55, is 4.6 from 1,378 amazon.co.uk ratings. The file behind that line includes 50 UK reviews. The named GWS 18V-8 is next for UK volume inside its sample, with 35 UK reviews behind 4.7 from 531. Length of sample is why the 240 V row is the house-socket top pick, alongside a voltage line that agrees with itself.
Who is the 230 V GWS 9-115 S for?
It is for house-socket work that wants speed selection: flap wheels, wire brushes, polishing and porcelain. The listing is £77.00, 900 W, 1.66 kg, part 0601396171, and 4.6 from 205. Style and voltage both say 230 V. It is a weaker pick when you need the torque reviewers associate with a 1,200 W grinder, or when the lead has to be 110 V. The fixed 11,000 rpm GWS 7-115 is the simpler row if you never change speed.
Is the £65 GWS 7-115 the bargain?
The shelf is £2.55 under the 240 V GWS 7-115, and the star line is 4.2 from 238. The style says 110V and the scope says 110 V, while the voltage field says 230 volts. UK reviews describe a yellow plug and faults that include smoke and a scorched cable. For a 13 A socket, the £67.55 listing is the one whose three voltage lines match.
Which cordless body if I already own the packs?
The named GWS 18V-8 at £89.44, part 06019N9000, is the bare body with the larger UK review share in its sample. It suits short cuts, and it does not print a disc diameter. If you need a 6-speed dial in the bullets, use part 06019N4000 at £148.99. Neither price includes a battery. Part 06019N4100 looks similar and does not state the dial.
Does 4.9 from 13 make the GWX the winner?
It makes a short, high star line on a £199.98 body with a paddle, a brake claim and an L-BOXX. The file has no UK review body. Non-UK reviews are the source for X-LOCK, which the bullets do not name. No battery is in the included line. Use it when you already own click-on discs and Professional packs and you want those bullet features. It does not replace the 240 V sample as a default.
