The best worx angle grinders, compared.
Top pick: Worx WX801.9 76 mm mini bare – Highest score in this comparison, 9.2 out of 10, from 729 amazon.co.uk reviews. Best value: Worx WX803.9 125 mm bare – Bare 125 mm body at about £81.41, with 4.5 from 736 ratings, if you already own 20 V packs. Updated October 2026.
A Worx angle grinder on amazon.co.uk is a Worx-branded hand-held grinder. This set is a 20 V cordless 125 mm tool, a 76 mm mini grinder, a 750 W corded 115 mm tool, or a hobby kit with a mini grinder. The decision is whether the battery is in the box. Judge a model by disc size, by a pack in the box or one you already own, by a named anti-kickback function, and by runtime you can believe. Do not rank on rpm. 19,000 rpm on a 76 mm disc is not more cutting power than 8,600 rpm on 125 mm. Size, power source and box contents are in the [Worx angle grinder buying guide](/hub/sanders/worx-angle-grinder/sub/worx-angle-grinder-buying-guide). The WX801.9 is a cordless 76 mm mini cutter at 19,000 rpm, sold bare, at a stated 1.1 kg.

Question 1 of 2
What are you cutting?
The Worx WX801.9 is a 76 mm mini cutter listed at £60.03, with 4.6 from 729 amazon.co.uk ratings and a no-load speed of 19,000 rpm. At 1.1 kg it is the lightest tool in this set, and the box includes two metal cutting discs, one diamond cutting disc and one roughing disc, all for the 76 mm size. Reviewers use it for light cutting, then report that it stalls or cuts out under heavy pressure, for example when grinding welds. That 19,000 rpm figure is the speed of a small disc, not extra cutting power compared with a 125 mm tool. Battery and charger are not included, and the listing does not name a side handle, anti-kickback or a warranty term. A 40 W power field on the listing is not a plausible motor rating, so it is not treated as the tool's power.
Pros
Cons
Best for: Someone cutting nails, bolts, thin tube or small tile in a tight spot.
Less suitable: Thick metal, weld grinding, or a job that needs a 115 mm or 125 mm disc.
Specifications
Common questions
Does the WX801.9 come with a battery and charger?
No. The listing says battery and charger are not included. It uses Worx 20 V PowerShare batteries.
What discs come in the box?
Two metal cutting discs, one diamond cutting disc and one roughing disc, all for the 76 mm size.
Can it grind thick metal?
Reviewers report it stalls or cuts out under heavy pressure, for example when grinding welds. It is a compact 76 mm tool for light cutting.
The Worx WX812 is a 125 mm cordless kit that arrives with a 4.0 Ah PowerShare battery and a charger, listed at £144.49 with 4.6 from 54 amazon.co.uk ratings. Reviewers describe strong cutting on the jobs they tried, and they say the electronic anti-kickback cut-out works when a disc jams. The listing names a brushless motor and a no-load speed of 8,500 rpm, so this is a full-size disc kit rather than a mini cutter. Reviewers also say the tool feels heavy once the 4.0 Ah pack is fitted, and the listing weight fields disagree (2.2 kg in a bullet, 4.46 kg as shipping weight), so no single weight is reliable. The included-components list shows no case, yet three reviewers mention one and one reports it broken on opening, which means you should check the current listing before you count on a case. Fifty-four ratings is a much smaller sample than the 736 on the bare WX803.9. The listing offers three years of cover if you register the tool online.
Pros
Cons
Best for: A first-time buyer who owns no Worx PowerShare battery and wants a 125 mm kit with a pack and charger.
Less suitable: Someone who already owns 20 V packs, or who wants a lighter mini cutter.
Specifications
Common questions
Does the WX812 come with a battery and charger?
Yes. The amazon.co.uk listing includes one 4.0 Ah battery and a charger. The battery is a Worx PowerShare 20 V pack, so it also fits other tools on that platform.
Does it have anti-kickback protection?
The listing names electronic anti-kickback, which shuts the tool down when a jam is detected. Reviewers say the cut-out works.
Does it include a carry case?
Unclear. The included-components list shows no case, but three reviewers mention one and one reports it broken on opening. Check the listing before you buy.
The Worx WX803.9 is a bare 125 mm 20 V grinder listed at £81.41, with 4.5 from 736 amazon.co.uk ratings, the largest review count in this set. It runs at 8,600 rpm, the listing weight is 2.07 kg, and the box includes an auxiliary handle, a cutting protector and a metal roughing disc. You still need a PowerShare battery and a charger, and UK reviewers say a smaller pack drains quickly under load. One reviewer recommends at least a 5.0 Ah battery, which is a single comment rather than a measured runtime. The amazon.co.uk listing does not name anti-kickback or a motor type, although Worx Europe's page describes this model as brushed and lists electronic anti-kickback. The listing also shows a 2,800 W power field, which is not a believable figure for a cordless tool, so that cell is not treated as power. The listing offers three years of cover if you register online.
Pros
Cons
Best for: An owner of Worx 20 V packs who wants a 125 mm body.
Less suitable: A buyer with no battery, or someone who wants anti-kickback written on the amazon.co.uk listing.
Specifications
Common questions
Does the WX803.9 include a battery or charger?
No. It is sold as a tool only. You need a Worx 20 V PowerShare battery and a compatible charger.
How long does a battery last on it?
The listing gives no runtime. Reviewers say a smaller pack drains quickly under load, and one recommends at least a 5.0 Ah battery.
Is anti-kickback listed?
The amazon.co.uk listing does not name anti-kickback or a motor type. Worx Europe's page describes this model as brushed and lists electronic anti-kickback.
The Worx MakerX WX990 is a two-tool hobby kit, not a full-size angle grinder: a brushless rotary tool and a 50 mm mini grinder share one hub, listed at £135.99 with 4.5 from 19 amazon.co.uk ratings. The kit includes a battery, a charger, a 35-piece accessory set and a storage case, and one reviewer puts the pack at 2.0 Ah. Reviewers say 38 mm discs fit with the supplied adapter, and they put the grinder speed in a band of about 14,000 to 24,000 rpm. They also say it is not suited to thick-metal grinding, and that replacement 50 mm discs are hard to find. Nineteen ratings is a small sample, and the listing ranks under Rotary Tools rather than Angle Grinders. If you need a 115 mm or 125 mm disc, this kit does not do that job.
Pros
Cons
Best for: Hobby detail work that needs a rotary tool and a tiny grinder together.
Less suitable: Steel, tile or any job that needs a 76 mm, 115 mm or 125 mm disc.
Specifications
Common questions
Is the WX990 a full-size angle grinder?
No. It is a rotary tool and a mini angle grinder on one hub. The grinder takes 50 mm discs, and 38 mm discs fit with the supplied adapter according to reviewers.
Are a battery and charger included?
Yes. The kit includes one lithium-ion battery and a charger. One reviewer puts the pack at 2.0 Ah.
Is it suited to thick metal?
Reviewers say it is not suited to thick-metal grinding, and replacement 50 mm discs are hard to source.
The Worx WX717 is a corded 750 W grinder for a 115 mm disc, listed at £60.36 with 4.0 from 22 amazon.co.uk ratings. It runs from a 230 V mains lead at 11,000 rpm, so there is no battery to buy, and the stated weight is 1.8 kg. The box lists an auxiliary handle, a metal grinding disc and an adjustable wrench, and the highlights name tool-free guard adjustment. The listing does not name anti-kickback, and it does not state the plug type or the cable length, so both have to be checked on the tool itself. Twenty-two ratings is a thin sample, and the review text held for this ASIN is not UK buyer comment, so the 4.0 stars are a count rather than a set of British jobs you can read. A 115 mm disc is a step down in size from the 125 mm cordless tools in this set. The listing states two years of cover, plus three if you register online, which is a different wording from the 2+1 years Worx UK publishes for a Worx-series tool registered within 30 days.
Pros
Cons
Best for: Work near a socket when you own no PowerShare pack and a 115 mm disc is enough.
Less suitable: Work away from a socket, or a buyer who wants anti-kickback written on the listing.
Specifications
Common questions
Does the WX717 need a battery?
No. It is a corded 230 V tool with a 750 W motor, so no battery or charger is needed.
Is the supplied disc a cutting disc?
No. One reviewer notes the disc in the box is a grinding disc, not a cutting disc. Protective equipment is not included.
What plug and cable length does it have?
The listing does not state the plug type or the cable length. One reviewer mentions about 2 m of cable. Check the photo and the box.
The figure beside each model is the amazon.co.uk star average scaled to 100. It is not a laboratory test. The top pick is the WX812 kit for a buyer with no Worx battery. The best value is the bare WX803.9 for someone who already owns 20 V packs. The weights below are the buying checks on this page. They sum to 100. Eight public sources sit under the page.
Disc class
30%A 125 mm tool (WX803.9, WX812) or a 115 mm tool (WX717) does steel and tile work. The 76 mm WX801.9 is for nails, screws, thin tube and tight spots. It is not a smaller version of a normal grinder.
Battery in the box
25%The WX803.9 and the WX801.9 are bare. Add a pack and a charger before comparing them with the WX812 kit. The WX717 needs no battery. The WX990 includes a pack and a charger.
Named safety features
20%The WX812 names electronic anti-kickback. The WX803.9 listing does not, although Worx Europe's page does. The WX717 names tool-free guard adjustment and does not name anti-kickback.
Runtime you can believe
15%UK reviewers describe a 2.0 Ah pack running flat quickly on the WX803.9. One says 5.0 Ah is the minimum. That is a comment, not a measured runtime. Do not rank these tools on rpm.
Review evidence
10%Read the count beside the stars. The WX803.9 is 4.5 from 736 and the WX801.9 is 4.6 from 729. The WX812 is 4.6 from 54. The WX717 is 4.0 from 22 and the WX990 is 4.5 from 19.
Start with the disc, then the box. A 125 mm or 115 mm tool does steel and tile. A 76 mm mini is for nails and thin tube. A bare price is not a kit price. Stored prices in this set run from about £60.03 to about £144.49 on amazon.co.uk.
A Worx angle grinder in this comparison is a Worx-branded hand-held grinder sold on amazon.co.uk. The five listings are not one tool. Two are cordless 125 mm grinders on the 20 V PowerShare platform: the WX803.9 is a bare body at 8,600 rpm, and the WX812 is a brushless kit at 8,500 rpm with a 4.0 Ah pack and a charger. The WX801.9 is a cordless 76 mm mini cutter at 19,000 rpm, sold bare, at a stated 1.1 kg. The WX717 is a corded 750 W, 115 mm grinder at 11,000 rpm and a stated 1.8 kg.
The WX803.9 at about £81.41 and the WX801.9 at about £60.03 do not include a battery or a charger. The WX812 at about £144.49 does. Add a pack and a charger before you treat the lower number as the cheaper finished tool.
UK reviewers describe a 2.0 Ah pack running flat quickly on the WX803.9, and one says 5.0 Ah is the minimum. That is a comment, not a measured runtime. The WX812 kit uses a 4.0 Ah pack. Budget a 4.0 Ah pack or a second pack.
The WX801.9 is 76 mm and 19,000 rpm. That speed is not extra cutting power. Reviewers say it stalls under heavy pressure, including welds. Do not use the free roughing disc to cut, and do not remove the guard to fit an oversize disc.
Disc size decides the job. The WX803.9 and the WX812 take 125 mm discs. The WX717 takes 115 mm. Those three are the steel and tile tools in this set. The WX801.9 takes 76 mm discs and is for nails, screws, thin tube and tight spots. The WX990 takes 50 mm discs on a hobby hub, and reviewers say replacement discs are hard to find. Then read the box. Kit means the WX812, with one 4.0 Ah PowerShare battery and a charger, or the WX990, with one battery and a charger.
The WX812 listing names electronic anti-kickback, and reviewers say the cut-out works. The WX803.9 listing is silent. Worx Europe's page lists electronic anti-kickback and describes the motor as brushed. The WX717 names tool-free guard adjustment and does not name anti-kickback. Keep the guard on. The disc's maximum rpm must be at least the tool's no-load speed. No listing here states a runtime, a vibration figure or a noise figure. A 2.0 Ah comment on the WX803.9 is not a lab result.
Three typical situations, each with a recommendation from this comparison.
You want a 125 mm body and you already have Worx PowerShare batteries and a charger. The WX803.9 is about £81.41, 8,600 rpm, with 4.5 from 736 ratings. The battery is not in the box, and reviewers say a smaller pack drains quickly under load.
You want a 125 mm grinder with a pack and a charger in the box. The WX812 kit is about £144.49, brushless, 8,500 rpm, with a 4.0 Ah pack and electronic anti-kickback, and 4.6 from 54 ratings. Reviewers say it feels heavy with that pack fitted. If you only work next to a socket, the corded WX717 is about £60.36.
You are cutting nails, bolts, thin tube or small tile in a tight spot. The WX801.9 is a 76 mm mini cutter at about £60.03, 19,000 rpm, about 1.1 kg, with 4.6 from 729 ratings. Stop when the metal gets thick. Battery and charger are not included.
If you own no Worx battery, the top pick is the WX812 kit at about £144.49. It is a 125 mm brushless tool with a 4.0 Ah PowerShare pack, a charger and electronic anti-kickback named on the listing, and 4.6 from 54 amazon.co.uk ratings. Reviewers say it feels heavy with the 4.0 Ah pack fitted, and 54 ratings is a smaller sample than the bare 125 mm tool. If you already own 20 V packs, the best value is the bare WX803.9 at about £81.41, with 4.5 from 736 ratings. Add a pack and a charger before you compare that price with the kit. The listing does not name anti-kickback. Worx Europe's page does.
