Best Angle Grinder 2026: 10 Ranked, and the Wattage Claims That Fail

It takes the top spot on the strength of one number: 21,959 ratings at 4.7 stars, the largest sample in this guide by five times over. The price is £78.64, the motor draws 720 W from a 230 V supply, and the disc is 125mm — the size most buyers end up wanting for general cutting and grinding.

Worth noting, Bosch quotes a 176 mm gripping circumference and the bullet lists 1.9 kg, which is light for a corded tool. In practice that matters more than wattage on long grinding jobs. The flat gear head is shaped for tight spaces, restart protection stops the tool firing up again after a power cut, and the carton includes the auxiliary handle, backing flange, guard, locking nut and a two-hole spanner.

Two things to weigh first. The horsepower field simply repeats the wattage — 720 in both — and 720 hp is roughly 537 kW, so that figure is a copy, not a measurement. Meanwhile the spec table says 2 kg where the bullet says 1.9 kg. That said, this is a corded angle grinder only, with no speed selection, so it suits plug-in work — where it remains the best angle grinder in the list.

At £78.54 this is ten pence cheaper than the 720 W model above it and 180 W stronger, which makes it the best angle grinder on paper for mains work. The 900 W motor is the highest genuine wattage in this guide. It also sits 5th in Amazon's Angle Grinders category, against 293rd for the GWS 7-125.

Speed selection is the feature that separates it from its cheaper sibling: you can slow the disc for stainless or thin sheet instead of running flat out. The spec table lists 1.66 kg, lighter than the 2 kg on the GWS 7-125, and the grip is described as small for control. The disc is 115mm, not 125mm, which means it takes the smaller of the two common wheel sizes.

The catch is the sample size: 203 ratings at 4.6, against 21,959 for the model ranked first. The included components field reads only 'GWS 9-115 S 2', so the box contents are not spelled out. If you want a 125mm disc, or thousands of buyers behind the score, this is not the one.

4,440 ratings at 4.7 — ten times the sample of any other cordless model in this guide. The price is £67.45, the lowest of the battery tools, and the disc is 115mm. It runs at 7,500 RPM, which is well under the 11,000 RPM of the corded models, so expect slower cutting in hard metal.

The Ryobi 18V ONE+ battery is the reason to buy it. Crucially, the same pack runs the rest of the ONE+ range, so a household already on that system adds a bare tool and nothing else. There is also a tool-less wheel guard that adjusts without a spanner, a 3-position auxiliary handle and a rubber overmould on the grip.

However, three things need reading twice. The horsepower field says 4 hp, and an 18V pack cannot deliver the roughly 3 kW that implies. The bullets state plainly 'Bare unit - no batteries supplied', so budget for a battery and charger on top of £67.45. At 2.62 kg it is heavier than several corded grinders here.

This is the lightest tool in the list at 1.22 kg, and with 489 ratings at 4.7 it has the second-best cordless sample behind the Ryobi. The disc is 125mm, so it takes the larger wheel size on an 18V battery. At £89.44 it undercuts both 18V DEWALT models by a wide margin.

Bosch lists a full scope of supply — backing flange, locking nut, two-hole spanner, auxiliary handle and protective guard — which the DEWALT listings do not. The design brief is light cutting and grinding: the bullets promise fast cutting for light applications and more work per charge. There is no RPM figure anywhere in the table, so speed is the one number you cannot check.

The catch is in the power fields. Wattage reads 800 and horsepower reads 800: the same number in two different units, and only one can be right. In theory 800 W is plausible for an 18V tool; in practice 800 hp is about 597 kW, which is a small diesel locomotive. The style field also confirms 'Without battery/charger', so a pack and charger are extra.

At £136.47 this is the most expensive tool in the guide, and its spec table is the boldest: 3,600 W, 1,000 horsepower and 9,000 RPM. The motor is 18V XR brushless, the rating is 4.7 from 530 buyers, and the feature list — electronic brake, electronic clutch, mesh debris covers — is the strongest engineering story here.

Those three features are the reason to pay. The electronic brake stops the wheel when you release the trigger, the clutch cuts the kickback if the disc pinches, and mesh covers keep dust out of the motor. As a result the tool is aimed at people cutting regularly rather than occasionally. The two-position side handle and rubber overmould are comfort items on top of that.

Then there are the numbers. A 3,600 W brushless angle grinder cannot exist as described: a 13 A plug passes roughly 3,000 W, and that is mains current, not an 18V pack. The horsepower field says 1,000, which is about 746 kW. The dimensions read 3.37 m long, 1.25 m wide and 1.56 m high. Even so, on the features alone it would be a serious contender for best angle grinder here; on the specification table it is the least reliable.

This is the top-ranked angle grinder in its Amazon category — 1st in Angle Grinders and 4,008th in DIY & Tools overall. The price is £107.50, £29 less than the other 18V DEWALT here, and the score is 4.6 from 67 ratings. By contrast with the dearer model, it carries the same electronic clutch, mesh debris covers and rubber overmould.

The spec table lists 18 volts, 2.39 kg and nothing else on performance — no wattage and no RPM. That makes it the harder of the two DEWALTs to judge on paper. It is also 190 g heavier than the £136 model, despite costing less. What you are buying is the brushless XR platform and the kickback clutch.

The dimension line is the giveaway: 10L x 10W x 10H millimetres, the size of a thumbnail, on a 2.39 kg tool. That is a placeholder, not a measurement. The included components field reads simply 'No', and 67 ratings is a thin base for a 4.6.

Two statements in this listing contradict each other. The product title reads 'with Battery and Charger' and the style field says '+ Battery & Charger'. The very first bullet then describes 'the Einhell cordless angle grinder TC-AG 18 Li – Solo'. In Einhell's naming, Solo means the tool alone, with no battery in the box. At £74.99 you are risking a body-only purchase at a kit price.

On the tool itself the numbers are modest and consistent: 8,500 RPM, a 115mm disc, 18V, and membership of the Power X-Change family, so batteries you already own for other Einhell kit will fit. The first bullet claims it is the lightest angle grinder in its class. The score is 4.6 from 68 ratings.

The catch is what the table does not say. There is no wattage figure, no weight and no battery capacity anywhere in the spec sheet. Either way, read the box contents before ordering and price a Power X-Change battery and charger alongside. As a £74.99 cordless angle grinder with no confirmed battery, it cannot be the best angle grinder in this list.

722 ratings at 4.1 puts this in the top eight and at the bottom of it. What lifts it is the kit: two 4.0Ah batteries, a charger, five cutting wheels, two flap discs, a stone cutting disc, goggles and a tool bag, all for £76.99. The motor is 21V brushless and the head runs at 9,500 RPM on the top setting.

Three speed settings — 3,500, 6,500 and 9,500 RPM — cover light grinding through to heavy cutting, and a 180° adjustable handle lets you swing the body to suit the cut. In practice the second battery is the point: 800 W at 21 V works out at roughly 38 A, which no 4.0Ah pack holds for long on its own.

The reservation is the score. 4.1 is the lowest rating in this list, 13 of the 722 reviews are one star, and the whole kit weighs 4.03 kg, which is heavy for overhead work. Even so, if you want two batteries and a full disc set in one box, nothing else here includes two packs.

This is the cheapest angle grinder in the guide at £59.99 and, alongside the two Bosch mains models, one of only three that states a wattage the mains can actually deliver: 750 W. The disc is 115mm. The rating is 4.4 from just 40 ratings, the smallest sample in the whole list.

The switch is the interesting part. A no-volt release stops the tool restarting after a power cut, so you have to reset it deliberately before the disc spins. The spindle lock sits on top for maximum depth of cut, and DEWALT supplies both a cutting guard and a grinding guard. At 2.45 kg it is heavier than the 720 W Bosch despite the lower power.

That said, the score needs context. Seven of the 40 ratings are two stars or below, about one in six. There is no speed selection and no battery option. In short, as a budget angle grinder for occasional cutting it works on paper; as your only tool for daily work, the ratings do not support it.
