The best mini angle grinders, compared.
Top pick: INGCO CAGLI76012 – Highest score in the set: 4.7 from 75 reviews, a stated 76 mm disc and one 2.0 Ah P20S battery, at about £55.99, with no penalty applied. Best value: TEENO TEENO-3608 – About £39.99 for two 2,000 mAh batteries and a stated 76 mm by 10 mm disc, 4.4 from 46 reviews, without the repeated dead-battery penalty. Updated October 2026.
A mini angle grinder is a cordless cut-off tool for a disc of about 75 mm or 76 mm. You buy one when a 115 mm guard will not reach a seized bolt, a short pipe, a tile notch, or light rust on a thin bracket. Check a stated disc diameter and bore, a guard that stays fitted, and a battery you can take off before a disc change. The disc label has to match the stated no-load speed. In this class the usual printed figure is about 19,500 rpm. A much higher printed speed needs a disc marked for that figure. Hand-held grinder accessories are capped at 80 m/s under BS EN IEC 62841-2-3. That limit is a standard, not a certificate for a kit. A toothed wood blade or a chainsaw disc does not belong on the spindle. Diameter, bore, speed, battery and the guard are set out in the [mini angle grinder buying guide](/hub/tools/mini-angle-grinder/sub/mini-angle-grinder-buying-guide).

Question 1 of 2
How many batteries do you want in the price?
The INGCO CAGLI76012 is a 20 V, 76 mm cutter listed at 19,500 rpm with an M6 spindle. UK reviews use it for small chassis and scrap-metal cuts rather than long grinding sessions. At about £55.99 the box holds one 2.0 Ah P20S battery, a charger, four metal cutting discs, two grinding discs, a wet diamond disc and a hex key. Across 75 amazon.co.uk reviews the line is 4.7, the strongest star pattern in this set, and buyers mention the battery indicator and a short job that felt easier than a full-size corded grinder. A reviewer who expected two batteries was told the kit has one, and the tool does not stand upright on that pack. It can stall under a heavy load, and one review describes the blade sticking on a cement flowerpot. The bullets claim about an hour to charge the 2.0 Ah pack. That claim was not timed for this comparison. It is the top pick when you can live with a single P20S battery and stay on light metal.
Pros
Cons
Best for: Short metal cuts in a tight space if you already use, or will stay with, INGCO P20S packs.
Less suitable: Continuous thick metal, a two-battery runtime, or a job that needs the tool to stand on its pack.
Specifications
Common questions
Does INGCO include a battery?
Yes. One 2.0 Ah battery and a charger. The bullets say P20S packs are shared with other INGCO tools.
What disc and spindle does the title state?
76 mm disc diameter and M6.
How many batteries are in the kit?
One. A UK reviewer had expected two and was told the kit has one.
TEENO’s TEENO-3608 is listed as a 16.8 V, 76 mm cutter at 19,500 rpm with a 10 mm bore, and the bullets limit it to domestic light cutting rather than continuous thick metal. At about £39.99 the title includes two 2,000 mAh batteries, a charger, six 76 mm cutting discs and a plastic carry case, though the included-components line only says 1. amazon.co.uk shows 4.4 from 46 reviews, and buyers mention light metal, rust removal and polishing, with the second pack so the work can continue. One review says the tool stopped before the first disc wore out, and another says spare parts are hard to find. The listing states 350 W and a weight of 1.83 kg. It is the best value in this set when you want two own-brand packs and a stated 76 mm by 10 mm disc. An early failure is already in the reviews, and the packs will not fit another brand.
Pros
Cons
Best for: Occasional DIY metal cuts if you want two batteries and a stated bore.
Less suitable: A shared battery platform, continuous thick section, or a job that needs a proven spare-part supply.
Specifications
Common questions
What disc does TEENO state?
76 mm diameter and a 10 mm bore, in the title and the bullets.
Are batteries included?
The title includes two 2000 mAh batteries and a charger.
What duty does the listing allow?
The bullets say domestic DIY and light cutting, and they say it is not for continuous cutting of thick metals.
The ConBlom ZN01581-UK is a 16.8 V brushed cutter listed at 28,000 rpm. UK reviews describe it as strong for the size on alloy and a coil spring, with enough charge for about ten bolts in a tight space. At about £42.99 the box lists two 2,000 mAh batteries, a charger, three metal cutting discs, a storage box and a wrench. The title says 76 mm, while the bullets also say grinding wheels of 75 mm by 10 mm. Across 150 amazon.co.uk reviews the average is 4.2. Several comments call that fair value, while others say the discs wear quickly and the tool cuts out after a period of cutting. Batteries that would not reach the stated 16.8 V come up more than once, and one case arrived smashed. The bullets say it is not for thick cast iron or concrete. Any disc you fit has to be marked for at least that 28,000 rpm claim. The speed was not measured for this comparison.
Pros
Cons
Best for: Short bolt and alloy cuts if you will only fit a disc marked for at least 28,000 rpm.
Less suitable: Thick cast iron, concrete, or a job that depends on the packs holding the stated 16.8 V.
Specifications
Common questions
What disc does the ConBlom listing state?
The title says 76 mm. The bullets say grinding wheels of 75 mm outer diameter and 10 mm thickness. Bore is given as that wheel size, not as a separate 22.23 mm grinder bore.
Does the price include batteries?
Yes. The bullets list two 2000 mAh batteries, a charger, three metal cutting discs and a storage box.
What speed does the listing claim?
28,000 rpm in the title and in the maximum rotational speed line. Match any disc to that figure. It was not measured for this comparison.
This Weytoll listing is the slow tool in the set: 7,000 rpm and 16.8 V at about £44.99. One reviewer preferred that speed to about 19,000 rpm for light panel and hobby cuts. The title states one 2,000 mAh battery, while several reviews describe two, and the listing does not state a disc diameter or a charger. amazon.co.uk shows 4.2 from 73 reviews, with praise for a neat kit in a box that the included-components line does not list. The same reviews say the batteries are tight to fit and remove, that some packs will not charge, and that an on/off switch fell off after a couple of uses. A blade holder was missing on arrival in one account, and the supplied gloves are called useless. At 1.82 kg it is not the lightest body here. Treat the 7,000 rpm figure as a listing claim you match to the disc. It was not measured for this comparison.
Pros
Cons
Best for: Light panel or hobby cuts if you want the lower stated speed and you check the box on arrival.
Less suitable: Anyone who needs a stated disc size, or a switch and charger the reviews already describe as unreliable.
Specifications
Common questions
What speed does this Weytoll listing state?
7,000 rpm in the title and in the maximum rotational speed line.
How many batteries does the title include?
The title says one 16.8 V 2000 mAh battery. Some UK reviews describe two batteries in the box.
Is the disc diameter stated?
No. The listing does not give a millimetre diameter or a bore.
Normodic’s 0HGPA is a bare 3 inch body at about £25.99 that claims Makita 18 V and 20 V packs such as BL1820, BL1830, BL1840, BL1850 and BL1860, and the price includes no battery and no charger. The bullets state 19,500 rpm, a guard, two 3 inch metal cutting blades, two grinding discs, goggles and gloves, and a maximum cutting depth of 20 mm. Only two reviews sit behind the 4.0 average. One says it is adequate for thin metal in a tight space, compares the feel to a basic Parkside cutter, and notes that it uses a pack you already own. A look inside the housing in that review describes brushes, not the brushless motor in the title, and the box has empty foam where batteries would sit. A review also describes an over-current cut-out if you push the cut. It is not a Makita tool, and two reviews cannot show whether those named packs stay reliable. At 1.3 kg the body is light. The real cost is the pack you supply, plus the contradicted motor claim.
Pros
Cons
Best for: A light trial only if you already own those packs and can return a brushed tool sold as brushless.
Less suitable: Anyone without a Makita 18 V pack, or anyone who needs a verified brushless cutter.
Specifications
Common questions
Does the price include a Makita battery?
No. The bullets say the pack does not include a battery or a charger.
Which batteries does the listing name?
Makita 18 V and 20 V examples printed in the bullets include BL1820, BL1830, BL1840, BL1850 and BL1860. That is a listing claim, not a Makita compatibility certificate.
Is it brushless?
The title says brushless. A UK review says the motor has brushes and no brushless controller.
The Rivlox GJ25903-2UK is the cheapest kit in the set at about £22.94: a 12 V brushed tool listed at 200 W, 19,500 rpm and 75 mm, with an M5 spindle and two 1,500 mAh batteries. The included line lists a charger, a wrench, five cutting discs and the grinder, at about 1 kg, and a case is not listed. Across 224 reviews the average is 3.6, the largest sample here, and buyers like the size for limited access and the low price. The same reviews say discs wear through on soft slate and only score a line, that the tool keeps stopping under load, and that battery life is poor. Early failure appears as a pack that will not charge, and one account says it stopped after three uses. The 1,500 mAh packs are smaller than the 2,000 mAh pairs elsewhere. It is a low-price compact cutter with a large review count, and the reviews do not treat it as reliable on masonry.
Pros
Cons
Best for: A cheap spare for occasional access cuts, if you have already read the cut-out pattern across 224 reviews.
Less suitable: Slate, tile, or any job where a dead pack in the first week is a problem.
Specifications
Common questions
What is in the Rivlox box?
The included-components line lists two 1.5 Ah batteries, a charger, five cutting discs, a wrench and the grinder. A case is not listed.
What spindle does the listing state?
A bullet says the spindle thread is M5. Disc diameter in the highlight is 75 mm.
What power does the listing state?
200 W, 12 V and 19,500 rpm.
Eborrkee’s 16.8 V listing claims 550 W and 19,500 rpm at about £29.99, with two rechargeable batteries, a charger, cutting discs and a suitcase. Capacity in amp-hours is not stated, and neither is the disc diameter. amazon.co.uk shows 3.5 from only three reviews, which is too small a sample to judge how long the tool lasts. Two short reviews call it compact for small areas and mention the two batteries and the case. One review says it arrived with open packets and only two blades. A bullet describes a wood cutting disc with hundreds of sharp teeth. A GOV.UK product safety alert warns against toothed saw blades on angle grinders, so that bullet is not a reason to buy. The listing also says it is not for cutting or polishing concrete. Three reviews and an unstated bore leave this as a kit you cannot judge for durability.
Pros
Cons
Best for: Only a buyer who will ignore the wood-disc bullet and still treat three reviews as too few.
Less suitable: Concrete, wood cutting, or any purchase that leans on a star average from three reviews.
Specifications
Common questions
How many reviews are on the listing?
3.5 from 3 reviews. That is too few to judge durability.
Are batteries included?
The included-components line lists two rechargeable batteries, a charger, discs and a suitcase. Capacity in Ah is not stated.
Does the listing mention a wood disc?
A bullet describes a wood cutting disc with hundreds of sharp teeth. Toothed blades on angle grinders are the subject of a UK safety alert. Do not treat that bullet as a recommendation.
JinsenTGG’s listing is about £30.98 with 288 reviews at 3.4, and the title says a 12 V brushless grinder with two 2,000 mAh batteries at 19,500 rpm. A bullet says brush motor, and UK reviews that opened or inspected the tool say it is not brushless. Cut-out every 5 to 10 seconds, or after about 20 seconds, is a repeated complaint, and reviews describe a stall on quarter-inch timber. One review says there is no way to charge. The listing does not confirm a charger, and packs are described as marked 16.8 V and 18 V rather than the title’s 12 V. A review says the manual’s spindle-lock button is missing and the spindle is an Allen bolt. Some buyers still report easy use and long battery life on tile removal. Disc diameter is not stated. The price looks like a two-battery kit until you set the brushless line against the reviews.
Pros
Cons
Best for: Only a buyer who already accepts a brushed own-pack cutter and can return it if it cuts out.
Less suitable: Anyone who chose it because the title says brushless, or who needs a continuous cut.
Specifications
Common questions
Is the JinsenTGG listing brushless?
The title says brushless. A bullet says brush motor. More than one UK review says it is not brushless.
What disc size is stated?
The listing does not state a diameter or a bore.
Are two batteries in the title?
Yes. Two 2000 mAh batteries. A charger is not confirmed on the listing.
The Geevorks E24188 is a 12 V, 75 mm cutter listed at 19,500 rpm and about £35.99, and the title includes a charger, two 2,000 mAh batteries and seven cutting discs. UK reviews call it handy for small bolt cuts and acceptable for light jobs, and some buyers describe it as fair value. The star line is 3.4 from 30 reviews. Supplied blades skate on a wall tile, runtime is described as about 5 to 10 minutes, and one or both batteries arrive dead in more than one account. A reviewer says the motor is not brushless, which the title never claimed. The listing does not state the bore, there is no case, and the listed weight is 1.73 kg. It is a closed own-pack kit for a short bolt, not a tile cutter.
Pros
Cons
Best for: A few small bolts, if both packs charge and you stay off tile.
Less suitable: Wall tile, heavy-duty cutting, or a job that needs more than a few minutes on one pack.
Specifications
Common questions
Does the Geevorks listing include a charger?
The title says it comes with a charger and two 2000 mAh batteries.
What disc size is stated?
75 mm in the title. Bore is not stated.
Is it described as brushless?
The title does not say brushless. A UK review says it is not a brushless motor.
This second Weytoll listing is about £28.99 and the weakest star line in the set, 2.7 from 13 reviews. The title says 21 V, two batteries and six discs, while the listing records the power source as AC/DC, states no voltage, and says the included components are no. A review says it is not 21 V. Battery life is poor in the comments: about four short tile cuts per charge, and it will not usefully cut 0.5 mm tile. One account says it was broken on first use. Bullets claim a spindle lock and a thickened baffle, and the weight is 1.24 kg, but the disc diameter is not stated. One short review says it is okay for small jobs, and a seller reply is noted. Thirteen reviews are enough to show voltage doubt and early failure, and they are not enough to rescue the listing.
Pros
Cons
Best for: Only after you have compared the 21 V title with the listing, which states no voltage.
Less suitable: Tile, a stated 21 V platform, or any job that cannot tolerate a first-use failure.
Specifications
Common questions
Does the listing say 21 V?
21 V is in the title only. The listing does not state a voltage, and the power source is recorded as AC/DC. A UK review says it is not 21 V.
What is included?
The included-components field says no. Bullets claim two 2000 mAh batteries and the title claims six discs.
What is the star rating?
2.7 from 13 reviews, the lowest star line in this set.
Ten amazon.co.uk listings were scored from the stored pages and the review notes already on file. Shelf date 21 October 2026. There is no laboratory test of rpm, noise, vibration or runtime. The highest score is the top pick. The value badge is the strongest sub-£40 kit that states a 76 mm disc and a 10 mm bore, includes two batteries, and does not carry the repeated dead-battery penalty. One of each. The weights below sum to 100.
Amazon stars
50%The listing star line is multiplied by 12 in the raw score, up to 60 points, then scaled into this weight. Stars are the amazon.co.uk line. They are not a workshop trial.
Review sample
20%A larger review count scores higher in the raw score, from 2 points under five reviews up to 15 points at 200 or more, then scaled. Two or three reviews cannot show durability.
Kit on the listing
20%A battery in the box, a second battery, a charger, a guard or baffle, and a case each add points in the raw score, then scaled. A missing line scores nothing for that part of the kit.
Listing checks
10%Points come off when a brushless title is described as brushed in UK reviews, when dead packs, cut-out or early failure repeat, when a review contradicts the title voltage, or when fewer than 10 reviews are on the listing.
Check the disc, the bore and the stated speed before the star line. Then check whether a battery and a charger are actually in the box. A brushless word in the title is not enough. None of these scores is a laboratory measurement.
A mini angle grinder here is a cordless cut-off tool for a disc of about 75 mm or 76 mm. You use it for a seized bolt, a short pipe, a tile notch or light rust where a 115 mm guard will not fit. Hire-shop “mini” often means a 115 mm tool. That is a different format, and so is a rotary multi-tool. Start with diameter and bore. 76 mm with a 10 mm hole is the usual size. A 115 mm disc uses a 22.23 mm bore, so the discs do not swap. In this set the stated sizes are 76 mm, 75 mm and a 3 inch body.
A hire-shop mini is often a 115 mm grinder with a 22.23 mm bore. This set is the 75 mm and 76 mm class. Those discs do not swap.
JinsenTGG’s title says brushless and a bullet says brush motor. UK reviews describe brushes. Normodic’s title says brushless and a review that opened the housing describes brushes. Neither is scored as brushless.
ConBlom states 28,000 rpm. Rim speed on 76 mm at that figure is about 111 m/s. The accessory cap in the grinder standard is 80 m/s. Match the disc label. That sum is not a certificate, and it is not a measured breach.
76 mm with a 10 mm hole is the usual size in this class. A 115 mm disc uses a 22.23 mm bore, so it will not fit these spindles. INGCO prints M6. Rivlox states M5. ConBlom and TEENO state a 10 mm hole, and ConBlom’s bullets also say 75 mm by 10 mm while the title says 76 mm. Geevorks and Rivlox state 75 mm. Normodic states 3 inch, which is 75 mm. Weytoll’s 7,000 rpm listing, JinsenTGG and the 21 V Weytoll do not state a diameter.
INGCO includes one 2.0 Ah P20S pack and a charger. Normodic claims Makita 18 V and 20 V packs and includes neither a battery nor a charger. The other kits are mostly closed 12 V, 16.8 V or title-only 21 V pairs of 1.5 Ah or 2.0 Ah. Eborrkee includes two batteries and does not state amp-hours. The 21 V Weytoll title is contradicted by a review, and the listing states no voltage. Reviewers describe minutes of cutting, or about ten bolts, not a shift.
Three typical situations, each with a recommendation from this comparison.
You need a short cut on a bolt, a stud or thin scrap where a 115 mm guard will not fit. The INGCO CAGLI76012 is the top pick at about £55.99: 76 mm, 19,500 rpm, one 2.0 Ah P20S battery, and 4.7 from 75 reviews. It can stall under a heavy load, and the kit is one battery.
You want a spare pack in the box and a stated bore. The TEENO TEENO-3608 is best value at about £39.99: 76 mm, a 10 mm bore, two 2,000 mAh batteries, and 4.4 from 46 reviews. One review reports failure before the first disc wore out. The bullets exclude continuous thick metal.
The Normodic 0HGPA is about £25.99 with no battery and no charger, and it claims Makita 18 V and 20 V packs. Only two reviews sit behind the 4.0 line. The title says brushless. A review that opened the housing describes brushes. Treat it as a light trial you can return, and compare it with a dealer 76 mm cutter before you rely on it.
The top pick is the INGCO CAGLI76012 at about £55.99: 20 V, 76 mm, 19,500 rpm, an M6 spindle, one 2.0 Ah P20S battery and a charger, with 4.7 from 75 reviews for short metal cuts. The best value is the TEENO TEENO-3608 at about £39.99, with a stated 76 mm disc, a 10 mm bore, two 2,000 mAh batteries and 4.4 from 46 reviews. It is the strongest sub-£40 kit in this set that states that disc and does not carry the repeated dead-battery penalty. The other listings are closed own-brand kits, a 7,000 rpm body, or a bare tool. None of these scores is a laboratory test.
