The best Makita 230 mm angle grinders, compared.
Top pick: Makita GA9050KX Best value: Makita GA9050R – About £78.52, the lowest shelf price, with 4.8 from 2,820 ratings. The title omits 230 mm and the speed row prints 5,000 rpm. Updated October 2026.
A 230 mm angle grinder is the deep-cut class. In the UK you buy one when a 115 mm or 125 mm disc cannot finish the cut, usually on paving or concrete. A rule of thumb is about 70 mm of depth, against about 30 mm on a 115 mm disc and about 38 mm on a 125 mm disc. Published depths in this class sit around 68 mm to 74 mm. The spindle is M14, the bore is 22.23 mm, and no-load speed is often 6,600 rpm. The disc must be marked for at least that speed. A domestic title is 240 V. A 110 V title needs a centre-tapped transformer. On site, use 110 V centre-tapped so voltage to earth stays at or below 55 V, or use a cordless body. Do not assume a UK plug from a photo. Keep the guard on, and unplug or remove the pack before a wheel change. If the title and the spec row disagree, ask a competent person.

Personal buying guide
Question 1 of 2
Where will you plug it in?
The GA9050KX is listed at about £128.29 as a 230 mm, 2,000 W corded Makita with a 230 V row and a synthetic case. The components line names two 230 mm wheels, a spanner, the case and a side handle, which is the clearest box in this set. The star line is 5.0 from three reviews, and the only written text is marked France, so it is not UK experience. That review calls the grinder powerful and precise, says a progressive start makes the weight manageable, and also calls it heavy. The bullets do not name a soft start or a no-load speed. The manufacturer page for this family is 6,600 rpm and 4.7 kg. At about £128.29 it costs more than the GA9020/2, which has 874 ratings, so the case and the two named wheels are the reason to pay the difference, not the star line.
Pros
Cons
Best for: You want the wheels and the case named in the components line, and you can accept a single non-UK review.
Less suitable: You want a large UK review sample, a printed speed row on the listing, or the lower GA9020/2 price.
Specifications
Common questions
Is the GA9050KX cordless?
No. The power source is corded electric, at 230 volts and 2,000 watts.
What is in the box?
The components line names two 230 mm wheels, a spanner, a synthetic case and a side handle.
Does the listing print a no-load speed?
No. The listing has no speed row. The manufacturer page for this family states 6,600 rpm. The horsepower row prints 2.68 horsepower.
The GA9050R is the lowest shelf price here at about £78.52, with 4.8 from 2,820 amazon.co.uk ratings. The title does not print 230 mm, and the written reviews in the file are marked Germany, Italy, Spain, France, Belgium or Poland, with none marked United Kingdom. Those non-UK texts praise cuts in granite, steel, brick and paving, and several mention a soft or delayed start, which the English bullets do not name. The amazon row prints 5,000 rpm, a horsepower line of 2 watts and a material of silica gel, while the English manual lists this model as 230 mm at 6,600 rpm, so those amazon cells are not the spec. One French review describes fitting a toothed blade to a stump, which is not an approved use. A German review expected a case and did not get one. The listing weight of 6.04 kg also fights the 4.7 kg manufacturer figure for this family. In this comparison it is the best value on shelf price if you use the manual figure and you do not treat the star line as UK experience.
Pros
Cons
Best for: You want the lowest shelf price and you will check the 230 mm, 6,600 rpm manual figure rather than the 5,000 rpm cell.
Less suitable: You need UK-marked reviews, a case in the box line, or a title that already says 230 mm.
Specifications
Common questions
Does the GA9050R title say 230 mm?
No. The title is Makita Angle Grinder GA9050R. The English manual lists this model as 230 mm at 6,600 rpm. The English bullets on the listing do not state the diameter.
What speed does the amazon row print?
5,000 rpm, next to 2,000 watts. The horsepower row prints 2 watts. That speed cell fights the manual figure of 6,600 rpm, so it is not the spec to use.
Are the written reviews from the United Kingdom?
No review in this file is marked United Kingdom. The star line is 4.8 from 2,820. That count is not a British sample of the plug, the disc or the case.
The GA9020/2 is the 240 V, 230 mm Makita in this set at about £107.99, and the amazon.co.uk line is 4.6 from 874 ratings. UK-marked reviews on file describe it cutting brick, concrete, paving slabs and a concrete step once a decent diamond disc is fitted. Reviewers call the build sturdy and the side grip stable, and several bought it to replace a Makita they had already worn out. The same UK texts say there is no soft start, so a hard start with a grinding disc is a handful, and the tool is heavy if you are not used to a 230 mm disc. More than one UK delivery arrived with a fitted Euro two-pin plug that the description did not mention, including a replacement. The box line names one disc, a side handle, a wheel guard and a spanner, but one UK review says the disc was not in the box. The spec row prints 220 V beside a 240 V title, so treat the title as the supply claim and still check the plug before you rely on a UK socket. In this comparison it is the top pick when you want a 240 V title and the only large UK-marked sample.
Pros
Cons
Best for: You are cutting paving or concrete near a domestic socket, and you will check the plug or have a competent person fit a UK plug.
Less suitable: You need a UK plug confirmed in the description, a soft start, or a 110 V site transformer.
Specifications
Common questions
Is the GA9020/2 cordless?
No. The listing gives the power source as electric, with a 220 V row and a 240 V title. No battery is in the box line.
Does the listing include a disc?
The included-components line says one disc, plus a side handle, wheel guard and spanner. One UK review says no blade arrived.
Does the listing say it has a soft start?
The bullets do not name a soft start. UK reviews say there is no soft start, and that a hard start is a handful with a grinding disc.
The GA9020RFK1 is listed at about £245.69 as a 230 mm, 2,200 W Makita in a case, with a 230 V row and no speed printed on the listing. The star line is 4.6 from only three reviews, and all three written texts are marked Germany, so they are not UK experience of the plug or the job. A Dutch bullet says soft start, which the plain GA9020/2 bullets do not. One German review says the machine and the case arrived, and that the two discs in the photo were not in the case, because the description did not say they were excluded. The manufacturer field prints EISAK while the brand line says Makita, so the carton may not match a clean Makita shop listing. The weight row says 4 kg, which is lighter than the 6 kg row on the GA9020/2 and lighter than the manufacturer range of 5.8–7.9 kg for a GA9020 without a cable, so 4 kg is not the settled mass. The manufacturer speed for this family is 6,600 rpm.
Pros
Cons
Best for: You specifically want the cased GA9020RFK1 suffix and you can accept a German review file.
Less suitable: You want UK-marked reviews, discs that match the photo, or a lower shelf price.
Specifications
Common questions
Is the GA9020RFK1 cordless?
No. The spec row is 230 volts and 2,200 watts, and the title is a cased corded grinder.
Does it come with a case?
Yes. The title says it is in a case, and a German review says the machine arrived with the case.
Are discs in the box?
The components line does not name discs. One German review says the two discs in the photo were not in the case, and the description did not say they were excluded.
The GA038GZ07 is a 40 V Max XGT brushless 230 mm body at about £319.90, and the title says the batteries and the charger are not included. The amazon.co.uk line is 4.3 from two ratings, with no written review text in the file, so there is no user account of runtime or of paving work. The bullets do name a paddle switch with lock-off, anti-restart, active feedback sensing, an electronic current limiter, a tool-less wheel cover and a spindle lock, plus a 6.5 mm maximum wheel thickness. An AWS chip, part 198900-7, is sold separately. Amazon’s weight row of 1 kg and size row of 10 × 10 × 10 mm fight a 230 mm body, so they are not the tool. The manufacturer with-battery range of 4.6–7.4 kg is the figure to use instead, and you still have to buy 40 V packs before it will run. Soft start is not in these listing bullets.
Pros
Cons
Best for: You already own 40 V XGT packs and want a 230 mm body without a lead.
Less suitable: You need a tool that runs from the box on a mains socket, or you are pricing this as a complete kit.
Specifications
Common questions
Does the GA038GZ07 include a battery?
No. The title says batteries and charger are not included, and the components line is the body only. You need 40 V XGT packs before it will run.
What safety features are in the bullets?
Paddle switch with lock-off, anti-restart, active feedback sensing, an electronic current limiter, and a tool-less wheel cover with spindle lock. Soft start is not in these listing bullets.
Can the amazon weight and size rows be used?
The rows print 1 kg and 10 × 10 × 10 mm. Those figures are not a 230 mm body. The manufacturer with-battery range is 4.6–7.4 kg.
The GA9050/1 is the only 110 V title in the set, at about £129.50, for a 230 mm Makita with 2,000 W on the item-type line and 6,600 rpm. The spec table prints 24 volts and 2 watts, which fights the title, so those two cells are not the supply. The star line is 3.9 from 11 reviews, and two of the five written texts are marked United Kingdom. A UK reviewer calls it a good work tool once the plug from the instructions is fitted, and another UK review says the bearings failed after two days. German and Spanish reviews also say it arrived without a plug. The label is 110 V, so it does not belong in a normal UK wall socket. The box line is the grinder itself: no disc and no case are named. The side grip can go on either side, and the gear housing can be set every 90 degrees.
Pros
Cons
Best for: You already have a 110 V centre-tapped site supply and a competent person to fit the plug.
Less suitable: You want a domestic 13 A socket, a disc in the box, or a larger UK review sample.
Specifications
Common questions
Is the GA9050/1 a 110 V tool?
The title and the item-type line say 110 V and 2,000 W. The spec table prints 24 volts and 2 watts, which fights the title. Use the title, and fit it to a centre-tapped 110 V supply.
Does it come with a disc or a case?
No. The included-components line is the grinder itself. A disc and a case are not named.
Does it arrive with a plug?
A UK review says to fit the plug from the instructions. German and Spanish reviews say it arrived without a plug. It is a 110 V tool, so it does not belong in a 13 A socket.
Six amazon.co.uk listings were scored from the stored pages, the review notes on file, and the manufacturer pages for the matching models. Shelf date 21 October 2026. This is not a laboratory cut. A star average is the listing line. A large count with no review marked United Kingdom is kept and reduced. The highest score is the top pick. The lowest shelf price among the other corded listings that still score 60 or above is the best value. One of each. The weights below sum to 100.
Amazon evidence
30%Star rating on amazon.co.uk, then a count bonus only when the written texts can be used. A sample of 200 or more with UK-marked reviews gets the full bonus. Fewer than 20 reviews loses points. A 5.0 from three reviews is not scored like a 4.6 from 874.
Listing fit
35%A 230 mm claim in the title, watts that match the suffix, a speed row that does not fight 6,600 rpm, a named handle or guard, and a box line that matches the photo. Rows that print 24 V, 2 W, 5,000 rpm, 1 kg or 10 mm do not earn fit points.
Review outcome
20%UK themes on paving, concrete or site work score higher than a single non-UK text. Missing discs, a Euro plug the description did not mention, and a bearing failure pull the block down. No written review means a low block.
Value
15%Shelf price in GBP against what the listing actually states. The lowest price does not win this block on its own when the title omits 230 mm or the review file is not marked United Kingdom. A body-only price does not include packs.
Read the title, the suffix and the box line before you read a star line. A 230 mm disc, an M14 spindle and a bore of 22.23 mm are the stable checks. A 240 V title, a 110 V title and a 40 V body are different supplies. A row that prints 5,000 rpm, 24 V, 2 W, 1 kg or 10 mm is not the tool. A star line with no UK-marked text is a listing aggregate, not a British sample.
A 230 mm angle grinder is the deep-cut class. You buy one in the UK when a smaller disc cannot finish the cut, usually paving or heavy grinding. A rule of thumb is about 70 mm of depth, against about 30 mm on a 115 mm disc and about 38 mm on a 125 mm disc. Published depths for the corded tools in this class are 68 mm and 74 mm, both at 6,600 rpm, with an M14 spindle and a 22.23 mm bore. A higher watt figure is not a deeper cut. The disc must be marked for at least the no-load speed.
A 115 mm or 125 mm grinder is a shallower cut. This category is the 230 mm class, with published depths around 68 mm to 74 mm. Do not buy the smaller body and treat it as this set.
Do not use 5,000 rpm, 24 V, 2 W, 1 kg or 10 mm as the tool. The manual figure for the 2,000 W family is 230 mm at 6,600 rpm. The 4 kg row on the cased 2,200 W listing fights the manufacturer range.
No stored row says BS 1363. A photo is not a UK plug. A toothed blade is not an approved attachment, including a stump blade described in one non-UK review. Keep the guard on.
Disc and spindle come first. This class is 230 mm, M14, with a bore of 22.23 mm, and the disc must be marked for at least 6,600 rpm where that is the stated speed. Supply is the check that stops a wrong plug. A 240 V title is the domestic claim. A 110 V title belongs on a centre-tapped transformer, not a 13 A socket. A 40 V listing here is a body only. No stored row says BS 1363. Do not swap those supplies.
What the components line names is the box. Guard, side handle, spanner, disc and case are either written there or they are not. Ignore the photo. One line names two 230 mm wheels and a synthetic case. One names a single disc, a guard, a side handle and a spanner. The 110 V line names the grinder itself. The cased 2,200 W title names a case, and a review says the pictured discs were not in it. The cordless title excludes the batteries and the charger. Keep the guard on.
Three typical situations, each with a recommendation from this comparison.
You want a 240 V title and UK-marked reviews on paving or concrete. The Makita GA9020/2 is the top pick at about £107.99, with 2,200 W, 6,600 rpm and 4.6 from 874 ratings. UK reviews also report a Euro plug, no soft start and one missing disc. Check the plug before you rely on a UK socket.
The Makita GA9050/1 is the only 110 V title, at about £129.50, with 2,000 W and 6,600 rpm. The spec table prints 24 V and 2 W. Drop that row. Reviews say it arrives without a plug, and one UK review reports a bearing failure after two days. Do not run it from a 13 A socket.
The Makita GA038GZ07 is a 40 V XGT 230 mm body at about £319.90, with a paddle, anti-restart and active feedback sensing. Batteries and charger are not included. The star line is 4.3 from two ratings and there is no written review. Amazon’s 1 kg row is not the tool. The manufacturer range with a battery is 4.6–7.4 kg.
The top pick is the Makita GA9020/2 at about £107.99. The title states 240 V and 230 mm, with 2,200 W and 6,600 rpm, and the amazon.co.uk line is 4.6 from 874 ratings. UK reviews describe paving and concrete, and also a Euro plug, no soft start and one missing disc. The best value is the Makita GA9050R at about £78.52, the lowest shelf price, with 4.8 from 2,820 ratings. The title omits 230 mm, no review is marked United Kingdom, and the listing speed row prints 5,000 rpm against a manual figure of 6,600 rpm. The GA9050KX is about £128.29, with two wheels and a case named, and 5.0 from three ratings, the only written text marked France. The GA9050/1 is the 110 V title at about £129.50, 3.9 from 11 ratings, with a spec row of 24 V and 2 W that is not the tool. The GA9020RFK1 is about £245.69 in a case, 4.6 from three ratings, all marked Germany, and the manufacturer field prints EISAK. The GA038GZ07 is a 40 V XGT body at about £319.90, 4.3 from two ratings and no review text, with no battery in the box. None of these scores is a laboratory test.
