Best Worx angle grinder

Updated: October 2026

The best Worx angle grinder in this set depends on whether a 20 V PowerShare battery is already on your shelf. If it is not, the WX812 kit is the top pick, because the listing includes a 4.0 Ah pack, a charger, a brushless motor and electronic anti-kickback. If you already own packs, the bare WX803.9 is the best value, and the kit’s extra money is mostly a battery you would buy twice. Shelf prices on 16 October 2026 were about £144.49 for the kit and about £81.41 for the body. Neither tool was lab-tested. A qualifying purchase can earn a commission at no extra cost to you. The full table is on the [Worx angle grinder comparison](/hub/sanders/worx-angle-grinder).

Top pick if you own no Worx battery

The top pick is the Worx WX812, ASIN B07ZHNCM2R, a 125 mm cordless kit at about £144.49 with 4.6 from 54 ratings. The listing names a brushless motor, 8,500 rpm, and electronic anti-kickback that shuts the tool down when a jam is detected. Reviewers say the cut-out works. The box contents that matter for a first kit are the 4.0 Ah battery and the charger, plus an auxiliary handle, a metal grinding disc, a wheel guard and a spanner. That grinding disc is for grinding. Cutting still needs a cutting disc of the right diameter and speed. Fifty-four ratings is a short record next to the bare tool. Weight is messy: a bullet says 2.2 kg and the shipping field says 4.46 kg, so neither figure is the tool in your hand. Reviewers say it feels heavy once the 4.0 Ah pack is on.

Who should skip the WX812

Skip the WX812 if you already own Worx 20 V PowerShare packs and a charger. You would pay about £144.49 for a platform you have. The bare WX803.9 at about £81.41 is the same 125 mm class of work. Skip it if the job is a protruding screw, a nail or a thin offcut. The 76 mm WX801.9 at about £60.03 is built for that. Reviewers flag the kit as heavy with the 4.0 Ah pack, and a case is not on the included-components list even though three reviewers mention one. The corded WX717 at about £60.36 suits a bench next to a socket, which the cordless and corded comparison covers. The MakerX WX990 at about £135.99 is a rotary tool and a 50 mm grinder, not a rival top pick. Disc class, if you are still unsure, is the buying guide.

Best value if you own PowerShare packs

The best value is the Worx WX803.9, ASIN B07R8Z3LFJ, at about £81.41 with 4.5 from 736 ratings. It is a 125 mm body at 8,600 rpm, listed at 2.07 kg, sold as tool only. It does not include a battery or a charger. If your packs are 4.0 Ah, the body is the cheaper way into a full-size disc. If the only pack is 2.0 Ah, UK reviewers say it drains quickly under load. One reviewer says 5.0 Ah is the minimum. That is one comment, not a runtime. Worx Europe’s page lists electronic anti-kickback and a brushed motor. The amazon.co.uk listing does not. Ignore the 2,800 W field. Adding a pack and a charger can close the gap to the kit, which is why the PowerShare battery page exists.

Why 736 ratings do not beat a named safety feature

The WX803.9 has 736 ratings at 4.5. The WX812 has 54 ratings at 4.6. A larger count is better evidence that buyers received a working 125 mm body. It is not evidence that the listing names the same features. Only the WX812 listing, in this pair, states a brushless motor and electronic anti-kickback. The bare tool’s listing is silent on both. Worx Europe attributes anti-kickback to the WX803.9, and that claim stays on the manufacturer page until the UK listing says the same thing. Best, here, means the kit when you own no battery, and the body when you do.

Common questions

Which Worx angle grinder is the top pick?
The WX812 kit is the top pick if you do not already own a Worx PowerShare battery. It is about £144.49, with a 4.0 Ah pack, a charger, a named brushless motor and electronic anti-kickback, and 4.6 from 54 ratings. It is a 125 mm tool. It is not the pick if you only need a 76 mm cutter.
Which is the best value?
The WX803.9 body is the best value at about £81.41 if you already own PowerShare packs and a charger. It has 4.5 from 736 ratings, a 125 mm disc and 8,600 rpm. The value disappears if you still have to buy a 4.0 Ah pack and a charger and you end up near the kit price with fewer features named on the UK listing.
Who should skip the WX803.9?
Skip the bare body if you own no battery and no charger. You cannot compare about £81.41 with about £144.49 until those parts are in the basket. Also skip it if you need anti-kickback written on the amazon.co.uk listing itself. Worx Europe names that feature. The UK listing used here does not.
Why is the WX812 the top pick with only 54 ratings?
The 54 ratings are a limit, not a hidden strength. The kit is the top pick because the listing includes a 4.0 Ah battery and charger and names a brushless motor and electronic anti-kickback. The WX803.9’s 736 ratings are stronger proof of broad satisfaction with a bare 125 mm body. They do not put a pack in the box.
Does the WX803.9 have anti-kickback?
The amazon.co.uk listing does not say so. Worx Europe’s WX803.9 page lists electronic anti-kickback and describes a brushed motor. Use the UK listing for what you can confirm at checkout, and the manufacturer page only as the manufacturer’s claim. Reviewers of the WX812, not of this body, are the ones who say a cut-out works.
