Best Angle Grinders in the UK (2026)

115mm for most people. It is the UK default disc size, so it is what every merchant stocks deepest and what the cheapest discs are cut for, and six of the seven picks below take it. 125mm gives you 5mm more radius, which is where depth of cut comes from, so it gets further into thick box section, slab and plate before you have to turn the work over. The DeWalt DCG407N-XJ at the top of this list is the 125mm option. If you cut sheet metal, angle, conduit, threaded rod and tile, stay at 115mm; if you regularly cut thick steel or masonry, the bigger disc earns its keep.

It is the voltage. Makita marks 110V site tools with /1 and 240V domestic tools with /2, which is why makitauk.com lists the same 720W 115mm grinder as both GA4530R/1 and GA4530R/2. UK building sites run 110V through a yellow transformer because it is far safer on a wet site, and a 110V tool simply will not run from a socket in your house without one. This matters on Amazon because both versions appear on the same search, at different prices, with the suffix as the only tell - the GA4530R/1 is one of the cheapest well-reviewed grinders on the whole UK shelf, and it is not ranked on this page because most people reading it cannot plug it in. DeWalt uses -LX for its 110V versions. Check the suffix before you buy.

It is the single feature most worth paying for, and it is not on most grinders at this end of the market. Without one the disc keeps spinning after you let go of the switch, which is when a lot of damage gets done - to a worktop, a cable, a leg - because the tool gets put down before it has stopped. An electric brake cuts that to a fraction of the coast-down time. Of the seven picks below, only the DeWalt DCG407N-XJ publishes one, and DeWalt also publishes a separate kick-back brake that fires when the tool jams. Makita's own manual for the DGA454 does not describe a brake for that model, which is why it is not credited with one here, though the newer DGA463 and DGA469 in Makita UK's current catalogue do publish one. None of the corded picks has a brake.

No, and this is the most expensive mistake in the category. Bosch Professional is the blue range - GWS, GSB, GBH codes - and runs its own 18V packs. Bosch Home & Garden is the green range - UniversalGrind, PWS, EasyImpact - and runs the 18V Power for All Alliance battery, which Bosch shares with other household and garden brands. A green pack does not fit a blue tool and a blue pack does not fit a green one. Both ranges are represented below: the corded GWS 7-115 is blue Professional and the cordless UniversalGrind 18V-75 is green Home & Garden. Amazon's listings blur the two constantly, so read the model name, not the picture.

A brushless one on a professional platform is. The two cordless picks at the top of this list are brushless tools on DeWalt 18V XR and Makita 18V LXT, and they are bought by people who cut steel for a living. A brushed cordless grinder is a different proposition: the Einhell Power X-Change and the Bosch green Home & Garden picks below are for short cuts, light dressing and getting somewhere a lead will not reach, not for standing in front of a job all afternoon. The honest comparison for sustained cutting is still a corded tool - it does not slow down as a pack drains and it never stops. Whatever you pick, remember every cordless grinder here is body only, so the real cost includes a pack and a charger unless you already own them.

Because it is a US-catalogue tool on a UK listing. Makita codes its UK and European 18V grinders DGA and its US ones XAG, so an XAG25Z advertised with a 4-1/2 inch or 5 inch disc is a grey import rather than UK stock. It is a real Makita and it will work, but it is sold without established UK warranty cover, so there is no straightforward route to a Makita UK service agent if the gearbox goes. That is why it is named in this guide and not ranked. The same check applies across the board: DeWalt uses -XJ and -GB for UK and European stock, and an unfamiliar suffix is worth ten seconds before you press buy.

They sell in real volume and some of them are rated well, so it would be dishonest to pretend they are not on the shelf. Four of them hold the bottom of the Amazon UK angle grinder listings - CHANTPOWER, DEKOPRO, Dong Cheng and KATSU - and one is ranked below, the CHANTPOWER, because it carries the most owner ratings of the four. What you give up is everything you would normally check: no manufacturer data sheet, no published power output or cutting depth, no UK service network, no registered warranty scheme, and in this case no published safety feature of any kind - no brake, no restart protection, no kickback cutoff. For a one-off job that is a reasonable trade. For a tool you reach for every week, the branded corded picks on this list cost very little more and publish what they are.

Black Friday falls on 27 November 2026 and is the deepest power-tool discounting of the year, followed by Boxing Day and the January sales. The next real window is the run-up to Easter on 28 March 2027, when the DIY and garden season opens and fencing, decking and paving jobs start, then the May bank holidays on 3 and 31 May and the August bank holiday on 30 August. Father's Day on 20 June 2027 moves a lot of mid-range tools. If you are buying through a business, the date that matters more is the tax year ending 5 April and what the Annual Investment Allowance lets you write off.
