The best 230mm metal cutting discs, compared.
Top pick: HAUTMEC 230 x 2.0 mm, pack of 10 Best value: Bosch PRO metal 230 x 3 mm – Best value for one bonded steel disc with a review count above 1,000, at £2.41, 4.6 from 1,253. Not marked stainless. Reviews often mention fast wear. Updated October 2026.
A 230 mm metal cutting disc is a consumable cut-off wheel for a large, 9 inch angle grinder. Buyers are cutting steel, stainless, rebar, pipe or angle. You tell the discs apart by thickness, about 1.9 mm or about 3 mm, by steel versus stainless, and by a bonded resin wheel versus a diamond metal wheel. Norton’s table following EN 12413 lists about 6,650 rpm for a 230 mm resinoid wheel at 80 m/s. That figure is a reference, not a speed measured here. The checks are on the [230mm metal cutting disc buying guide](/hub/sanders/230mm-metal-cutting-disc/sub/230mm-metal-cutting-disc-buying-guide). The bore is usually 22.23 mm, sometimes written 22.2 mm. The disc must match a grinder and a guard rated for 230 mm. Do not put a 230 mm disc on a 115 mm or 125 mm grinder. A reducer ring is only the one supplied with that disc.

Question 1 of 2
What are you cutting?
The HAUTMEC listing is ten 230 x 2.0 x 22.23 mm aluminium-oxide discs at £27.99, with 6,600 rpm and an EN 12413 and MPA claim. The amazon.co.uk score is 5.0 from only six ratings, and the raw file has two short positive UK comments. That sample is too small to treat as a settled rank against Parweld’s 196 ratings. The compatible-devices line names a die grinder, which is not a tool for a 230 mm disc; the bullets specify a 9 inch angle grinder with a 22.23 mm arbor. Grit is 46. At about £2.80 a disc the pack is dearer than Parweld without the review depth. Country of origin is China and the pack weight is 2 kg.
Pros
Cons
Best for: You want a 2.0 mm ten-pack and you will ignore the die-grinder line and check the disc label.
Less suitable: You are treating a 5.0 from six ratings as proof, or you need a large UK review file.
Specifications
Common questions
How many reviews support the 5.0 score?
Six amazon.co.uk ratings, with two short positive UK comments in the file. That is not the same evidence as a 4.5 from 196.
Will it fit a die grinder?
The compatible-devices line names a die grinder. A 230 mm disc does not belong on one. The bullets specify a 9 inch angle grinder with a 22.23 mm arbor.
What speed and standard are claimed?
6,600 rpm, with EN 12413 and MPA claimed. The pack is ten 230 x 2.0 mm discs at £27.99.
The WojBear listing is one diamond cut-off wheel, described as 230 mm and 1.8 mm thick, at £25.99, with a stated 6,650 rpm. The amazon.co.uk line is 5.0 from three ratings. One of two short UK reviews says it cut a steel post at ground level. Lines such as 5,000 cuts are seller text, not a measurement for this comparison. The bore is stated as 22 mm with a 20 mm reducer, not the usual 22.23 mm. An item-dimensions line of 11.4 cm does not match 230 mm. No safety mark is listed. At 630 g it is a steel-bodied wheel, not a thin resin disc, and three ratings are not a basis for a life claim. A reducer is only the one supplied with that disc. It is not a way to put a 230 mm wheel on a faster small grinder.
Pros
Cons
Best for: You want one diamond wheel for steel and you will check the bore and the printed diameter on the box.
Less suitable: You need a 22.23 mm bore without a reducer guess, or a review file larger than three ratings.
Specifications
Common questions
Is 5,000 cuts a measured result?
No. Lines such as 5,000 cuts are seller text. The amazon.co.uk line is 5.0 from three ratings. One short UK review describes a steel post cut at ground level.
What bore does the listing state?
22 mm, plus a 20 mm reducer. That is not the usual 22.23 mm bore. A reducer is not a way to fit a 230 mm wheel to a small grinder.
Does the size line agree?
The title says 230 mm and 1.8 mm thick. An item-dimensions line of 11.4 cm does not match 230 mm. Check the printed diameter on the box.
This Bosch inox and metal disc, part 2608601514, is listed at £3.24 with 4.7 from 41 amazon.co.uk ratings. The item type says 230 x 1.9 x 22.2 mm. A bullet in the same raw file says 1.75 mm and 22.75 mm. The title and the number of items say one disc, while the unit-count field says 25, so the packet is the check. The abrasive line is WA 36 R BF. It does name stainless and metal, which the plain 3 mm steel Bosch rows do not. Weight is 168 g. The conflicts are a reason to read the disc label, not a reason to assume a box of 25 has arrived.
Pros
Cons
Best for: You want a single thin inox disc and the packet in your hand matches 230 x 1.9 mm.
Less suitable: You need an unambiguous listing, or you are only cutting mild steel where a 3 mm steel disc is enough.
Specifications
Common questions
Which thickness is printed?
The item type says 230 x 1.9 x 22.2 mm. A bullet in the same file says 1.75 mm and 22.75 mm. Read the disc label.
Is it a 25-pack?
The title and the number of items say one disc. The unit-count field says 25. Do not assume a box of 25 has arrived.
Does it name stainless?
Yes. The listing names stainless and metal. The amazon line is 4.7 from 41 ratings at £3.24.
The Bosch PRO inox disc, part 2 608 600 711, is a depressed-centre wheel listed as 230 x 1.9 x 22.23 mm, with EN 12413 and a country-of-origin field of Germany, at £4.59. The amazon.co.uk line is 4.7 from 33 ratings, which is a thinner file than the straight inox disc at the same price. Bosch states up to 1.3 times the life of its standard metal disc 2608619769. That is the manufacturer’s comparison, not a test run for this page. A dimensions line of 10 x 10 mm contradicts the 230 mm diameter and should be ignored in favour of the diameter field. Bosch’s UK page for this part describes the disc as iron free. Weight is 180 g and the grit field says 80.
Pros
Cons
Best for: You want one depressed-centre inox disc and the Bosch part the UK page describes as iron free.
Less suitable: You need a large review file, or you are only cutting mild steel.
Specifications
Common questions
Is the 1.3 times life line a test result?
No. Bosch states up to 1.3 times the life of its standard metal disc 2608619769. That is the manufacturer’s comparison, not a test run for this page.
Does Bosch call this disc iron free?
Bosch’s UK page for part 2 608 600 711 describes the disc as iron free. The amazon line is 4.7 from 33 ratings, which is a thin file.
Which size line should you use?
The diameter field is 230 x 1.9 x 22.23 mm. A dimensions line of 10 x 10 mm contradicts that and should be ignored.
The Eternox title is ten 230 mm, 3.2 mm, T42 ferrous discs at 6,600 rpm for £24.00, with EN 12413 and MPA claimed. The written reviews in the raw file describe 115 mm discs, a 50-piece story and 13,300 rpm, so those comments are not evidence for this 230 mm pack. The amazon.co.uk line is 4.7 from eight ratings. Bore is not stated. The construction-type field says coated. The bullets say ferrous metals, including steel and iron, and they do not say stainless. The listed weight of 2.87 kg is at least consistent with a ten-pack of thick discs. Buy it only if you can see 230 x 3.2 mm on the discs themselves.
Pros
Cons
Best for: You can inspect a 230 x 3.2 mm ferrous pack in person and you will ignore the mismatched reviews.
Less suitable: You are using the star rating as proof of 230 mm performance, or the job is stainless.
Specifications
Common questions
Do the reviews describe this 230 mm pack?
No. The written reviews describe 115 mm discs, a 50-piece story and 13,300 rpm. Those comments are not evidence for this 230 mm title.
What does the title claim?
Ten 230 x 3.2 mm T42 ferrous discs at 6,600 rpm, for £24.00, with EN 12413 and MPA claimed. The bore is not stated. Stainless is not named.
How is it rated on amazon.co.uk?
The listing shows 4.7 from eight ratings. That star line is not proof of 230 mm performance when the review texts describe another size.
This Bosch PRO metal listing, part 2 608 600 226, is shown as 230 x 3 mm with a 22.23 mm bore and oSa in the title, at £6.30, with 4.6 from 1,275 ratings. The speed field says 8,500 rpm. A 230 mm resinoid wheel at 80 m/s is about 6,650 rpm on Norton’s table following EN 12413, so that field matches the 180 mm row, not a target for this diameter. One UK review says that, unless you buy by part number, the page is a 115 x 2.5 mm disc. The listed weight is 99.8 g, which is light next to the other Bosch 230 x 3 mm discs at 270 g. Read the number printed on the disc. Do not set a grinder from the amazon speed field.
Pros
Cons
Best for: You can match part 2 608 600 226 on the packet and you will follow the rpm printed on the disc.
Less suitable: You would set the grinder from the amazon speed field, or you cannot check the diameter on arrival.
Specifications
Common questions
Should I run this disc at 8,500 rpm?
No. That amazon field matches the 180 mm row on Norton’s table, not a 230 mm wheel at 80 m/s. Use the rpm printed on the disc. Do not set the grinder from the field.
Why do reviews mention 115 mm?
One UK review says that, unless you buy by part number, the page is a 115 x 2.5 mm disc. Match part 2 608 600 226 on the packet and check the diameter.
How is it rated on amazon.co.uk?
The listing shows 4.6 from 1,275 ratings at £6.30. The star line does not remove the speed conflict or the weight of 99.8 g.
The Bosch PRO metal disc, part 2 608 603 162, is a single 230 x 3 x 22.23 mm depressed-centre wheel for steel at £2.41. Across 1,253 amazon.co.uk ratings the score is 4.6, one of the two largest files in this set. UK comments split between a usable cut in heavier steel and discs that wear down very quickly. The title carries an oSa mark, and the listing does not print a maximum rpm, so the number on the metal ring is the speed that counts. It does not say stainless or inox. At 270 g it is one consumable, not a workshop pack. It is the best value row when you need one stiff steel disc and you accept ordinary bonded-disc wear.
Pros
Cons
Best for: You want one stiff 3 mm steel disc for occasional mild-steel cuts on a 230 mm grinder.
Less suitable: The job is stainless, or you will make enough thin cuts that a pack is the cheaper way to work.
Specifications
Common questions
Is this Bosch disc for stainless steel?
No. The listing says metal and steel. It does not say stainless or inox. A steel-only disc can contaminate a stainless edge.
What speed is printed?
The listing does not print a maximum rpm. Use the number on the metal ring. Norton’s table lists about 6,650 rpm for a 230 mm resinoid wheel at 80 m/s, as a reference.
How is it rated on amazon.co.uk?
The listing shows 4.6 from 1,253 ratings at £2.41. UK comments include fast wear. Stars are Amazon scores, not a lab test.
The Bosch PRO metal disc, part 2 608 603 168, is a flat-hub steel wheel, 230 x 3 x 22.23 mm, at £8.95 with 4.6 from 1,193 ratings. It is not the same disc as the depressed-centre part 2 608 603 162 at £2.41. The components line says A 30 S BF, while the grit field says 36. A dimensions line of 10 x 10 x 10 mm is junk against the 230 mm diameter field. One UK buyer switched to these after a cheaper disc failed and reports no blowouts on angled cuts in box steel. Another says to wear a coverall and the rest of the protective kit. Wear is still described as normal for a bonded disc, and oSa is in the title. The listing says metal and steel, not stainless, and it does not print a maximum rpm.
Pros
Cons
Best for: You specifically want a flat-hub 3 mm steel disc and a large review file.
Less suitable: You only need the cheapest single steel disc, or the job is stainless.
Specifications
Common questions
Is this the same disc as the £2.41 Bosch?
No. This is part 2 608 603 168, a flat-hub wheel at £8.95. The £2.41 disc is part 2 608 603 162, depressed centre. Both are 230 x 3 mm steel discs.
Does the listing say stainless?
No. It says metal and steel. It does not print a maximum rpm. oSa is in the title.
How is it rated on amazon.co.uk?
The listing shows 4.6 from 1,193 ratings. One UK review reports no blowouts on angled box-steel cuts. Stars are Amazon scores, not a lab test.
The Bosch straight cutting disc, part 2608619770, is the top pick here when you want one 230 x 1.9 x 22.23 mm wheel marked for sheet, rebar, steel and stainless, without a speed or diameter conflict in the capture. The amazon.co.uk line is 4.6 from 180 ratings at £4.59. One UK buyer cut two scaffolding poles with one disc. Another says it is not the best blade they have used. A review describes flex and a snap when the cut pinched, which is the usual risk with a thin disc if the kerf closes. Maximum rpm is not printed on the listing, so the disc label still decides the speed. At 180 g it is a single consumable. A long morning of cuts still wants a pack rather than another single.
Pros
Cons
Best for: Mixed steel and stainless cuts where you want a straight Bosch disc and a listing you can read without a size clash.
Less suitable: Heavy bar that needs a 3 mm disc, or a workshop that will use up singles in one morning.
Specifications
Common questions
What size is this Bosch disc?
The capture gives 230 x 1.9 x 22.23 mm, a straight profile, for sheet, rebar, steel and stainless. Maximum rpm is not printed on the listing.
Does a review describe a failure?
Yes. A review describes flex and a snap when the cut pinched. That is the usual risk with a thin disc if the kerf closes. Stop if the disc cracks.
How is it rated on amazon.co.uk?
The listing shows 4.6 from 180 ratings at £4.59. Stars are Amazon scores, not a lab test.
The Parweld TF070 pack is ten 230 x 1.9 mm discs for mild steel and stainless, listed at 6,600 rpm and £12.96, about £1.30 a disc. The amazon.co.uk line is 4.5 from 196 ratings. A UK reviewer says the thin discs flex as they come up to speed and are hard to place until they are spinning, and the same review says not to force them. The grade line is A60TBF and the bullets claim EN 12413. The bore is printed as 22.2 mm rather than 22.23 mm. Country of origin is not stated. The pack suits a run of thin cuts if you keep the feed light and you check the bore on the packet.
Pros
Cons
Best for: You have a run of thin cuts in mild steel or stainless and you will not twist the disc in the kerf.
Less suitable: You need a stiff 3 mm disc for heavy section, or you only have one cut to make.
Specifications
Common questions
What metal does the Parweld pack name?
Mild steel and stainless. The discs are 230 x 1.9 mm, ten in the pack, at £12.96. The bore is printed as 22.2 mm.
What do UK reviews say about flex?
A UK reviewer says the thin discs flex as they come up to speed and are hard to place until they are spinning. The same review says not to force them.
What speed is stated?
The listing states 6,600 rpm and claims EN 12413. Use the number on the disc if it differs. Do not side-load a cutting disc.
The Bosch EXPERT diamond metal wheel, part 2608900536, is £51.98 on amazon.co.uk with 4.5 from 95 ratings. The title, the item type and Bosch’s UK page for that part say 230 mm. The item-diameter field says 180 mm, so the box is the check. The bullets say cast iron, rebar, steel and stainless, and they say not to use the wheel on aluminium, concrete or stone. A compatible-material field says aluminium, which contradicts those bullets. Thickness is not stated, the listed weight is 500 g, and the origin field says the Republic of Korea. Bosch’s longer-life line for this wheel is a manufacturer claim. The higher price on Bosch’s own UK shop is a different channel, not this amazon price. Do not merge the two prices.
Pros
Cons
Best for: Repeated metal cuts where you accept Bosch’s exclusions and you confirm the wheel in the box is 230 mm.
Less suitable: Aluminium, masonry, or a single short cut where a bonded disc at a few pounds is enough.
Specifications
Common questions
Is the diameter 230 mm or 180 mm?
The title, the item type and Bosch’s UK page say 230 mm. The item-diameter field says 180 mm. Confirm the wheel in the box before you fit it.
Can it cut aluminium or concrete?
The bullets say not to use the wheel on aluminium, concrete or stone. A material field that says aluminium contradicts those bullets. Follow the exclusion.
Which price is used here?
The amazon.co.uk shelf price is £51.98. Bosch’s UK shop price is a different channel and is not merged with this listing.
The Merryland title is a 25-piece set of type 41 discs, 230 x 1.9 x 22.23 mm, at 6,650 rpm and £46.90. If the carton really holds 25, that is about £1.88 a disc. The number-of-items field says 1 and the weight is 190 g, which looks like one disc, so the packet is the check, not the title alone. The amazon.co.uk line is 4.4 from 138 ratings. Some UK reviews call the discs hard wearing. One buyer says a disc lasted about five minutes and three were used. The bullets say steel and stainless, and EN 12413 and MPA are claimed. The grade line is A36T-BF.
Pros
Cons
Best for: A workshop that will open the carton and confirm 25 discs before relying on the unit price.
Less suitable: A one-off cut, or anyone who cannot check the piece count on arrival.
Specifications
Common questions
Does the listing really contain 25 discs?
The title says 25. The number-of-items field says 1 and the weight is 190 g, which looks like one disc. Open the carton before you rely on a unit price.
What metal and speed are stated?
The bullets say steel and stainless, type 41, 230 x 1.9 mm, at 6,650 rpm. EN 12413 and MPA are claimed.
How is it rated on amazon.co.uk?
The listing shows 4.4 from 138 ratings at £46.90. Life comments split, including one disc said to last about five minutes.
Twelve amazon.co.uk listings were scored on 19 October 2026. Weights sum to 100. There was no lab test. Norton’s published table following EN 12413 lists about 6,650 rpm for a 230 mm resinoid wheel at 80 m/s. That figure is a reference, not a speed measured on a grinder. A 5.0 from three or six ratings is not scored like a 4.6 from more than a thousand. An amazon speed field of 8,500 rpm is not scored as a faster 230 mm disc.
Amazon evidence
30%Star rating on amazon.co.uk, then a heavy deduction when the count is under about 50 ratings, and a lighter one under 200. A 5.0 from three or six ratings is not scored like a 4.6 from more than a thousand.
Listing fit
35%A stated 230 mm diameter, a bore near 22.23 mm, thickness, metal words that match the job, a speed near 6,600–6,650 rpm when one is printed, and a safety line when the listing states it. Conflicts deduct, including an 8,500 rpm field, reviews of a 115 mm disc, or a unit count that disagrees with the title.
Review outcome
20%UK themes that describe a finished cut score higher than fast wear, flex until the disc is up to speed, a snap when the kerf pinches, or a review set that is about a different diameter.
Value
15%Shelf price in GBP against pack size and what the listing states. A cheap single scores here. A 25-pack does not, when the items field says 1.
The checks run in this order: diameter and bore, metal, thickness, speed and the date, then bonded versus diamond. The table is the twelve listings. There was no lab test. Use the rpm on the wheel.
A 230 mm metal cutting disc is a consumable cut-off wheel for a large, 9 inch angle grinder. The bore is usually 22.23 mm, sometimes written 22.2 mm. Buyers are cutting steel, stainless, rebar, pipe or angle. The disc must match a grinder and a guard rated for 230 mm. Do not put a 230 mm disc on a 115 mm or 125 mm grinder. A reducer ring is only the one supplied with that disc. It is not a way to put a 230 mm wheel on a faster small grinder.
Type 41 and type 42 in this set are for cutting. Do not side-load them. A thin disc that flexes needs a light feed, not more pressure.
The Eternox written reviews describe 115 mm discs and 13,300 rpm. One Bosch review says the page is a 115 mm disc unless you buy by part number. Those texts are not a 230 mm result.
Resin-bonded hand-held wheels carry a use-by date, commonly three years, on the metal ring. Do not use an expired, dropped or cracked disc.
Stainless or inox on the listing is the line you need for stainless. The £2.41 Bosch and the flat-hub Bosch are steel. The straight Bosch inox, Parweld, HAUTMEC and the other Bosch inox rows name stainless. A steel-only disc can leave contamination in a stainless edge. About 1.9 mm is the narrow slot and the one that flexes as it spins up. About 3 mm is the stiff disc for heavier bar. The Parweld review describes flex until the discs are up to speed.
Stay inside the rpm on the wheel. 6,600 rpm and 6,650 rpm are the figures this set mostly prints. 8,500 rpm on one Bosch field is the 180 mm reference, not a faster setting for 230 mm. EN 12413, oSa or MPA, when the listing states them, still means the guard stays on and the date on the ring is in date. A single at £2.41 is one job. A ten-pack is a run of cuts, and the unit price only counts if the carton matches the title.
Three typical situations, each with a recommendation from this comparison.
You want a straight 230 x 1.9 mm wheel marked for sheet, rebar, steel and stainless, without a speed or diameter clash in the capture. The Bosch straight inox disc is £4.59, with 4.6 from 180 ratings. A review describes flex and a snap when the cut pinched.
You want a single 3 mm depressed-centre steel disc and a review count above 1,000. The Bosch PRO metal disc is £2.41, with 4.6 from 1,253 ratings and oSa in the title. It does not say stainless. Reviews often mention fast wear.
You will buy thin discs in tens and you will not twist them in the kerf. The Parweld ten-pack is £12.96 for 1.9 mm mild steel and stainless, at a stated 6,600 rpm. A UK review says the discs flex until they are up to speed.
The top pick is the Bosch straight inox disc, part 2608619770, at £4.59. It is 230 x 1.9 x 22.23 mm for sheet, rebar, steel and stainless, with 4.6 from 180 ratings and no speed or diameter conflict in the capture. A review describes flex and a snap when the cut pinched, and rpm is not printed on the listing. The best value is the Bosch PRO metal disc at £2.41, a depressed-centre 230 x 3 mm steel wheel with 4.6 from 1,253 ratings. It is not marked stainless, and reviews often mention fast wear. A 5.0 from three or six ratings is not the top score. Do not run a 230 mm disc at 8,500 rpm because one amazon field says so.
Bosch PRO metal 230 x 3 mm
Best value for one bonded steel disc with a review count above 1,000, at £2.41, 4.6 from 1,253. Not marked stainless. Reviews often mention fast wear.
