Bosch angle grinder buying guide

Updated: October 2026

You open amazon.co.uk, filter for Bosch, and ten small angle grinders appear that look like one family. Some are blue, some are green, some show a battery in the photo and some show only the bare body. The shelf price runs from about £44 to £200, and 18 V on the title does not tell you whether your existing packs will fit. This Bosch angle grinder buying guide walks through the decisions in the order that matters on a UK listing. Match an ASIN on the main Bosch angle grinder comparison once the platform is settled.

Start with the socket or the battery you already own

Corded tools in this set plug into UK mains. The GWS 7-115 states 240 V, 720 W, and 11,000 rpm at about £67.55, with a guard and no disc. The GWS 9-115 S at about £77 adds speed selection on a 900 W, 230 V body. Neither is Bosch’s 110 V site order. Cordless rows are 18 V on two rails that do not share packs. Blue Professional batteries do not fit green POWER FOR ALL tools. Read Bosch blue or green angle grinder before you compare wattage. If you own neither rail, corded mains is the exit, and the UniversalGrind 750-115 at about £44 names three cutting discs.

What the amazon price includes

Only the UniversalGrind 750-115 states cutting discs in the box. The GWS 7-115 and GWS 9-115 S list a guard and spanners, so budget a disc rated for the printed speed. Cordless rows are mostly body-only: the GWS 18V-8, both 1,100 W blue bodies, and the UniversalGrind 18V-75 body. The green kit at about £155.15 names a 4.0 Ah battery and AL18V-20 charger. The PWS 18V-70 scope line is only a cardboard box. The GWX18V-11PS includes an L-BOXX and does not name a battery or X-LOCK.

Speed dial or one speed

A dial matters when the material changes mid-job. The GWS 9-115 S is the corded option at about £77. The six-speed body at about £148.99 advertises six steps, and Bosch’s UK page for model 06019N4000 matches a GWS 18V-11 S even though the amazon title omits that name. The GWS 18V-8 is a fixed-speed body for light cuts. The about £135.95 blue body adds a quick nut, but a UK review says it has no speed control despite S-style photos. The green corded UniversalGrind has no variable speed in a UK comment. A dial you never touch is wasted money.

Disc size before you chase power

Titles that state a size in this set are mostly 115 mm. The six-speed blue body is the 125 mm-class outlier when you cross-check a UK review title and Bosch’s order number, while the GWS 18V-8 listing still conflicts between 115 mm copy and a 125 mm review. Do not plan to fit a larger disc on a smaller guard because the M14 thread accepts it. The guard is the limit. That physics belongs on Bosch angle grinder 115 or 125. Decide diameter before you fall in love with a wattage number.

A short decision

Green POWER FOR ALL packs point to the UniversalGrind 18V-75 body or the 4.0 Ah kit. The PWS 18V-70 only makes sense if you accept a bare box. Blue Professional 18 V points to the GWS 18V-8 for light work, and to the six-speed or quick-nut rows when speed or disc changes matter more. With no Bosch battery, the GWS 7-115 is the large review file, the GWS 9-115 S is the dial, and the about £44 UniversalGrind is the row when discs in the box matter more than branding. A 4.9 line on thirteen reviews is not 1,378 reviews on the GWS 7-115.

Common questions

Do I buy corded or cordless first?

Choose corded if you have a reliable socket, long sessions, and no Bosch 18 V packs already. Choose cordless if you already own the matching blue or green rail and you accept body-only pricing plus your own discs. Mixed ownership, green mower packs and a blue drill, is common. It does not merge the rails.

Will my existing Bosch batteries fit?

Only if the colour and system match. Professional 18 V packs do not fit POWER FOR ALL green tools, and Gardena’s UK support states the mechanical coding differs. There is no official adapter in the alliance FAQ. Match the platform before the model name when the title only says 18 V.

Is the cheap green tool a false economy?

The UniversalGrind 750-115 at about £44 includes three cutting discs and suits light DIY cutting. It is not a Professional battery tool, and reviews say there is no variable speed. False economy appears when you buy green because it was cheap, then discover your blue packs never fit.

Which listings include a disc or a battery?

Discs stated: the UniversalGrind 750-115 only. Battery and charger stated: the green UniversalGrind 18V-75 kit with 4.0 Ah. Everything else in this set expects you to supply at least one of those items. A guard in the scope line is not the same as a wheel or a pack.

Is the £77 GWS 9-115 S a site 110 V tool?

No on this amazon capture: it lists 230 V. Bosch sells a separate 110 V order number for site transformers. Check the specification table and the plug on delivery if your site mandate is 110 V. These kept corded rows are domestic 230 V or 240 V tools.

When is six speeds worth more than the GWS 18V-8 body?

When you change material or finish often enough that a dial saves discs and time, and you already own Professional packs. For straight cuts and the largest review sample on a blue body, the GWS 18V-8 remains the simpler cordless row. The six-speed shelf price is about £148.99, and no battery is in the box.

What should I ignore in the horsepower field?

Treat marketing horsepower or vague power lines as secondary to stated wattage, voltage, disc size, box contents, and review themes about heat, guards, and battery drain. None of that replaces reading the scope line on the exact ASIN you add to basket.
