The best 9 inch angle grinders, compared.
Top pick: Hilka PTGA2000 Best value: Einhell TE-AG 230/2000 – About £68.99, soft start, tool-free guard, 4.0 from 2,536 reviews. No cutting disc in the box. Updated October 2026.
A 9 inch angle grinder is a 230 mm disc machine. In the UK both names mean the same class: a two-hand corded tool for deep cuts in masonry, slabs, kerbs and thick metal. You recognise a suitable machine by a stated 230 mm disc, a wheel whose marked speed is at least the tool's speed, a guard, a side handle and a spindle lock. Soft start matters because a motor around 2,000 W can snatch. Home sockets are nominally 230 V with a BS 1363 plug. Many sites use 110 V from a transformer, so the label has to match the supply. A model code that begins with 9 is a power class on some ranges, not a disc diameter. Retailer guides put a typical 230 mm depth near 65–70 mm, against about 30 mm for a 115 mm disc. Printed speeds are often 6,000 or 6,500 rpm, and the disc's marked rpm must be at least the grinder's speed. Label, plug and box contents are set out in the [9 inch angle grinder buying guide](/hub/tools/9-inch-angle-grinder/sub/9-inch-angle-grinder-buying-guide).

Question 1 of 2
Where is the work?
The Hilka PTGA2000 at about £54.95 sits between the DEKOPRO and the Einhell 2,000 W on price, with 2,000 W and 230 V on the listing and a 4.94 kg weight that is the lightest single 230 mm body in this set. The amazon.co.uk line shows 5.0 from only five reviews, so that score is not a settled rank you should weigh like the Einhell's 2,536. Speed, guard adjustment and box contents are largely unstated on the capture. The model line on the listing reads PTAG2000. UK reviewers who supplied a diamond blade describe cutting a concrete block wall and call the tool heavy but robust. It may suit you if you want a lighter corded 9 inch body for occasional block work and you accept buying discs and verifying features yourself.
Pros
Cons
Best for: You want a lighter, lower-cost 230 mm grinder for occasional block or slab cuts and you will choose discs yourself.
Less suitable: You want soft start, a large review sample, or a stated guard and speed line before you pay.
Specifications
Common questions
How many reviews are there?
The listing shows 5.0 from 5 reviews. The stored file contains three review texts, so the score is a small sample.
Does the listing state a no-load speed?
No. Wattage is 2,000 W and voltage is 230 V. Speed is not stated.
What did buyers say?
Reviewers cut a concrete block wall with a diamond blade they supplied, and one called it heavy but robust.
The Evolution R230DCT at about £119.95 is the top pick in this comparison when your job is masonry slabs, blocks or kerbs rather than freehand metal grinding. It is a wheeled 230 mm disc cutter, not a handheld angle grinder: the listing states 2,000 W, 6,000 rpm, a diamond masonry blade in the box and a 90 mm depth of cut, with a dust port and rubber cap. The amazon.co.uk line is 4.7 from 609 reviews. UK reviewers praise straight slab cuts; others say the guard does not swing like a grinder guard, the dust port did little even with a vacuum, and one measured depth nearer 3.5 inches than the title figure. At 7.1 kg it is heavier than the Hilka or Bosch handheld rows. It fits paving-heavy work; skip it if you need a side-handle grinder for metal fabrication.
Pros
Cons
Best for: You cut paving, blocks or kerbs regularly and want a dedicated 230 mm cutter with a blade in the box.
Less suitable: You need a side-handle grinder for metal, or you only have a few small cuts where hire is cheaper.
Specifications
Common questions
Is this a handheld angle grinder?
No. The title calls it a disc cutter, concrete saw and cut-off saw, with a wheeled skid plate. It uses a 230 mm blade.
What depth of cut does the listing state?
The title states a 90 mm cut. One reviewer measured nearer 3.5 inches on their machine.
Does it collect dust?
The listing includes a dust port with a rubber cap. One UK reviewer says the port did little even with an industrial vacuum.
The Einhell TE-AG 230 2,350 W at about £82.59 adds 350 W over the 2,000 W sibling, with soft start, a spindle lock, a quick-release guard clamp and a three-position anti-vibration handle at 6,500 rpm on the listing. The amazon.co.uk line is 4.3 from 73 reviews. The title suggests a disc, but several UK reviewers say none arrived; the stated included components are the grinder and a face spanner. More than one UK review reports the spindle-lock button breaking or falling out, which makes disc changes awkward or unsafe. At 6.4 kg it is heavier than the 2,000 W model. Choose it if you want the extra wattage and quick-release guard and you will check the box and lock on delivery; otherwise the larger-review 2,000 W Einhell is the calmer value bet.
Pros
Cons
Best for: You want more motor headroom than the 2,000 W Einhell and you will test the spindle lock and guard on arrival.
Less suitable: You need a trustworthy spindle lock out of the box, or you want the 2,536-review Einhell without lock complaints.
Specifications
Common questions
Does a disc come in the box?
The highlight mentions a disc. Several UK reviewers say no disc arrived. The stated included components are the grinder and a face spanner.
Is the spindle lock reliable in the reviews?
The title lists a spindle lock. More than one UK reviewer says the button broke or sprang out, so the disc could not be changed normally.
How is the guard adjusted?
Bullets say disc protection adjusts without tools. One reviewer found the quick-release clamp fiddly and said the nut must be tightened hard.
The Bosch GWS 22-230 P at about £156.07 is the expensive corded 230 mm row here, with 2,200 W, an anti-vibration auxiliary handle, and guard, flanges and a spanner in the box. The amazon.co.uk line is 4.3 from 26 reviews. The specification prints 120 V, while a UK reviewer reports a 230 V tool with a UK three-pin plug and calls the 120 V line wrong. Treat both lines as signals to check the label on delivery. The listing does not claim soft start, and a UK reviewer says the motor kicks when switched on. At 5.5 kg it is mid-weight for this set. It fits you if you want a Bosch Professional body for regular masonry or metal and you accept verifying voltage and a snatchier start than a soft-start Einhell or DEKOPRO.
Pros
Cons
Best for: You want a Bosch Professional 230 mm grinder for repeated site or workshop cuts and you will confirm voltage and plug on arrival.
Less suitable: You need soft start on a budget, or you only cut occasionally and can use a mid-price Einhell instead.
Specifications
Common questions
Is the voltage 120 V or 230 V?
The listing prints 120 V. A UK reviewer says the tool is 230 V with a UK 3-pin plug and that the 120 V line is wrong.
Does it have soft start?
The listing does not claim soft start. A UK reviewer says there is none and that the tool kicks when switched on.
What is in the box?
The listing includes the grinder, an anti-vibration handle, backing flange, locking nut, protective guard, two-hole spanner and a cardboard box. A case is not listed.
The JCB 21-AGTPK at about £90.50 puts a 115 mm grinder and a 2,000 W 230 mm grinder in one carton, with anti-vibration side handles and tool-free guards on the listing. That suits you if you want a small grinder for dressing work and a 9 inch machine for deeper masonry without buying two brands separately. The amazon.co.uk line is 4.1 from 26 reviews, so the sample is thin. UK buyers praise getting jobs done; others mention stiff switches, oil in the packaging, or cosmetic marks on arrival. The 8.04 kg figure is the whole pack, not a single tool. The printed 11,000 rpm is not split by machine. It is the wrong buy if you only need one 230 mm grinder or if you already own a 115 mm model.
Pros
Cons
Best for: You want both a 115 mm grinder and a 230 mm grinder in one delivery and you will use the smaller tool as well.
Less suitable: You only need a 9 inch grinder, or you already have a 115 mm machine you trust.
Specifications
Common questions
Is this only a 9 inch grinder?
No. The listing is a twin pack with a 115 mm grinder and a 230 mm grinder.
Does it have a two-stage trigger?
Yes. The title states a two-stage trigger and a tool-free adjustable guard.
What do UK reviews mention most?
Reviewers say the tools get the job done. Others report stiff switches, an oil leak in the box, or a set that arrived marked.
The Einhell TE-AG 230/2000 at about £68.99 is the best value pick among general 230 mm angle grinders here because the amazon.co.uk line is 4.0 from 2,536 reviews, far larger than the Bosch or JCB samples, and the listing states 2,000 W, 6,500 rpm, soft start, a spindle lock and a tool-free guard. The highlight is explicit: no cutting disc in the box, so you must budget for a diamond or abrasive wheel rated for at least the printed speed. UK reviews split between brick and slab work and first-use failures where the tool sparked and stopped in masonry dust. At 5.63 kg it is lighter than the 2,350 W Einhell sibling. It fits landscapers and householders who will buy the right disc separately and accept Einhell-grade durability rather than trade-brand prices.
Pros
Cons
Best for: You want a widely reviewed 230 mm grinder with soft start and you will supply a legal disc for your stone or metal.
Less suitable: You need a diamond blade in the carton on day one, or you want the wheeled Evolution cutter for long slab runs.
Specifications
Common questions
Does it include a cutting disc?
No. The item highlight says without a cutting disc.
Is the guard tool-free?
Yes. The bullets say the guard adjusts without tools, and the side handle mounts in three positions.
What failures show up in reviews?
Some UK reviewers say the tool sparked and stopped on the first masonry cut. Others report it cutting brick and slabs. It is not a quick-release disc system.
The DEKOPRO 230 mm grinder at about £45.89 is the entry price in this set, listed at 2,200 W and 6,500 rpm with soft start, a spindle lock, and a 230 mm grinding wheel in the box. The amazon.co.uk line is 3.9 from 45 reviews, so the file is smaller than the Einhell 2,000 W row. UK buyers who fit the side handle report long concrete sessions; one reviewer could not screw the handle in because the thread looked damaged or badly cut. At 6.14 kg it is heavier than the Hilka listing but still a handheld 230 mm shape. It suits occasional slab or block work when you want soft start and a wheel included without paying Bosch money, provided you inspect the handle threads on arrival.
Pros
Cons
Best for: You need a corded 230 mm grinder for occasional cuts and you want soft start plus a wheel in the box on a tight budget.
Less suitable: You want the largest UK review file, or a side handle you cannot afford to refit or return.
Specifications
Common questions
Does a grinding wheel come with it?
Yes. The listing says the box includes a 230 mm grinding wheel, a wheel guard, an auxiliary handle and a wrench.
Is the side handle straightforward to fit?
The listing says the handle mounts on the top, left or right. One UK reviewer could not screw it in because the thread was damaged or badly cut.
Is it cordless?
No. The specification says corded electric, 2,200 W. One review mentions a battery, which conflicts with that line.
Seven amazon.co.uk listings were scored from the stored pages and the UK review notes already on file. Shelf date 19 October 2026. There is no laboratory test. Stars are the listing line. A 5.0 from five reviews is not scored like a 4.7 from 609. The highest score is the top pick. Best value is the corded 230 mm angle grinder with soft start and a review count above 500. One of each. The weights below sum to 100.
Amazon evidence
30%Star rating on amazon.co.uk, then a heavy deduction when the count is below about 50 written UK reviews, and a lighter deduction below 200. A thin five-review line is not treated as a settled rank.
Listing fit for 230 mm work
35%Stated 230 mm or 9 inch class, wattage in the 2,000 W band, printed speed where present, guard and side handle, spindle lock, soft start when claimed, and a disc or blade note that matches the title.
Review outcome
20%UK themes that match masonry or metal use score higher than stiff switches, oil in the box, spindle-lock failures, or a side-handle thread that will not fit.
Value
15%Shelf price in GBP against what the listing actually states. The cheapest row loses this block when reviews report quality or safety complaints.
Buy the disc class and the voltage before you buy a star line. A 9 inch tool and a 230 mm tool are the same class. A model code that starts with 9 is not a disc diameter. A five-review line is not a settled rank, and a dust port is not workplace extraction.
A 9 inch angle grinder takes a 230 mm disc. UK shoppers use both names for the same class. It is a two-hand corded tool for deep cuts in masonry, slabs, kerbs and thick metal, not the usual tool for bolts or tiles. Judge a listing by a stated 230 mm disc, a disc rated for the grinder's speed, a guard, a side handle, a spindle lock, and a voltage that matches the socket. Soft start matters because a motor in the 2,000 W band can snatch.
Bosch GWS 9-115 is a 115 mm grinder. The 9 is a power class. Only a stated 230 mm or 9 inch disc belongs in this comparison.
The Bosch GWS 22-230 P listing prints 120 V. A UK reviewer reports 230 V and a UK 3-pin plug. Quote both. Check the label and the plug on delivery. Do not rewrite the listing.
The Hilka line is 5.0 from five reviews. That is not scored like 4.7 from 609 or 4.0 from 2,536. Speed and guard are largely unstated on that listing.
Only a stated 230 mm or 9 inch disc belongs here. A code that starts with 9 can still be a 115 mm grinder. Retailer guides put a typical 230 mm depth near 65–70 mm and a 115 mm depth near 30 mm. Those are guides, not a cut measured on your slab. There is no universal one-pass depth. The Evolution states 90 mm for its wheeled cutter only. Corded 230 mm tools kept in this set are 2,000–2,350 W. Printed speeds are 6,000 or 6,500 rpm.
Look for a guard, a side handle and a spindle lock in the listing, not in a guess. Soft start matters if a 2,000 W motor snatching on start worries you. The Bosch listing does not claim soft start, and a UK reviewer says there is none. The DEKOPRO and both Einhell listings do claim it. Several UK reviews of the 2,350 W Einhell say the spindle-lock button failed. Home use is 230 V with a BS 1363 plug. Sites often use 110 V from a transformer.
Three typical situations, each with a recommendation from this comparison.
You have a few thick slabs, you will buy a disc for that stone, and you want soft start on a corded 230 mm grinder. The Einhell TE-AG 230/2000 is the best value at about £68.99, with 4.0 from 2,536 reviews. No cutting disc is in the box. Some UK reviews report a first masonry cut that sparked and stopped.
You cut slabs, blocks or kerbs often and you want a wheeled 230 mm cutter with a diamond blade. The Evolution R230DCT is the top pick at about £119.95, with 4.7 from 609 reviews and a stated 90 mm depth. It is not a side-handle grinder. Reviews say the guard does not swing and the dust port is weak.
You want a Bosch Professional 230 mm body for repeated masonry or metal, and you will check the plug on arrival. The GWS 22-230 P is about £156.07, at 2,200 W, with 4.3 from 26 reviews. The listing prints 120 V. A UK review reports 230 V and a UK plug. Soft start is not stated, and a reviewer reports kick on start.
The top pick when the job is masonry slabs, blocks or kerbs is the Evolution R230DCT at about £119.95. It is a wheeled 230 mm disc cutter with a diamond blade, a stated 90 mm depth, and 4.7 from 609 reviews. It is not a side-handle grinder. The best value among general corded 230 mm grinders is the Einhell TE-AG 230/2000 at about £68.99, with soft start and 4.0 from 2,536 reviews, and no cutting disc in the box. The Bosch GWS 22-230 P is the highest shelf price, at about £156.07, and its listing prints 120 V against a UK review that reports 230 V. The Hilka line is 5.0 from five reviews, which is not a settled rank. None of these scores is a laboratory test.
Einhell TE-AG 230/2000
About £68.99, soft start, tool-free guard, 4.0 from 2,536 reviews. No cutting disc in the box.
