The best 125mm metal cutting discs, compared.
Top pick: HAUTMEC HT0431 discs (10) Best value: Merryland Craft-Line discs (25) – Printed 125 x 1.0 x 22.23 mm, 12,250 rpm and EN 12413 at £10.90 for 25. The 8,007 reviews match the 50-pack text, the thickness field says 0.05 inches, and that shared text includes fast wear and injury claims. Updated October 2026.
A 125 mm metal cutting disc is a thin resin-bonded cut-off wheel, or sometimes a steel-body diamond wheel, for a 125 mm angle grinder with a 22.23 mm bore. You need it for steel, stainless, tube, sheet or bolts. A tile disc, or a 115 mm disc, does not belong here even when the bore matches. Check the 125 mm guard, a marked rpm the grinder does not exceed, about 1.0–1.2 mm thickness, EN 12413 on a bonded wheel, and a use-by date on the metal ring. Those 8,007 stars match the 50-pack, so they are not a second test. The order of checks is on the [125 mm metal cutting disc buying guide](/hub/sanders/cutting-disc-125-metal/sub/cutting-disc-125-metal-buying-guide). The usual bore is 22.23 mm, which is 7/8 inch. A few listings are steel-body diamond wheels instead.

Personal buying guide
Question 1 of 2
What are you cutting?
HAUTMEC HT0431 is a 10-pack in a tin at £10.99. The title is 125 x 1.0 x 22.23 mm, with aluminium oxide, 12,250 rpm, 80 m/s, EN12413 and an MPA claim. A bullet then says the discs fit all standard 115 mm grinders. The star line is 4.8 from 13, and the file has four UK reviews: a padlock, 6 mm 316 stainless, and a buyer who ordered 125 mm for a 115 mm grinder and left the sealed tin unused. There is no grit number. Treat the title diameter as 125 mm and ignore the 115 mm sentence when you choose a guard.
Pros
Cons
Best for: You want a small tin of 1.0 mm discs and you will follow the 125 mm title, not the 115 mm bullet.
Less suitable: You need a large review sample or a page with no size clash.
Specifications
Common questions
Are these 115 mm or 125 mm discs?
The title, the diameter field and the included-components line say 125 x 1.0 x 22.23 mm. One bullet says they fit all standard 115 mm angle grinders with a 22.23 mm bore. Follow the 125 mm title when you choose the guard.
What do the few UK reviews say?
Four texts are in the file. They describe an easy padlock cut, a 316 stainless bar, and a buyer whose grinder only takes 115 mm.
Is 4.8 from 13 a stable score?
The listing prints 4.8 from 13. That count is too small to treat as a settled rate.
The DeWalt DT42340TZ is a flat 125 x 1.2 mm stainless cutting disc, listed at £9.99 on amazon.co.uk and rated 4.7 from 1,117 reviews. The bullets name an aluminium oxide formula, fibreglass reinforcement, EN 12413 and a metal box of 10. UK reviewers describe fast cuts on stainless and steel, including rusty coachbolts and a 10 mm RSJ, and several say they last longer than cheap Screwfix discs. The same file has no bore and no rpm, a 135 g item weight, a second dimension block of 45 x 35 x 15 cm, and a number-of-items field of 1. Reviews also include a tin that is hard to open, a disc that rubs the guard, wobble on a mains grinder, and one first-use disintegration. One review title names a 115 x 1.2 mm tin. In this set it is the top pick where you want a named stainless ten-pack with a large UK star count, and you still read the disc ring for speed and expiry because the page does not print them.
Pros
Cons
Best for: You want a DeWalt 125 mm stainless ten-pack and you can read the disc itself for bore, rpm and expiry.
Less suitable: You need a printed 12,250 rpm line, a 1.0 mm kerf, or a bore confirmed on the page.
Specifications
Common questions
Does this DeWalt pack name stainless steel?
Yes. The title, the bullets and the item type name say it is a flat stainless steel cutting disc, 125 mm x 1.2 mm.
What maximum speed is printed?
None. The specification tables do not give rpm or a bore. Read the metal ring for speed and the use-by date before you fit the disc.
How many discs are in the box?
The title, the set name and the bullets say 10 in a metal box. The number-of-items field says 1.
The Merryland C13081042-50 is the Craft-Line 50-pack at £20.90, about £0.42 a disc. The bullets match the 25-pack on size, 12,250 rpm, EN 12413, two mesh layers and stainless / INOX. The model-number field is 6970465123917, the set name says 40 UK, and the weight is 1.6 kg. It is rated 4.6 from 8,013 reviews, and those UK blocks are the same as the 25-pack, including praise for life against Würth and DeWalt and complaints about fast wear, shards and a finger injury. Buy the 50-pack for the unit price when you already accept that review stream, not because 8,013 is a second study.
Pros
Cons
Best for: You get through a lot of 125 mm discs and want the lowest unit price among packs that print 22.23 mm and 12,250 rpm.
Less suitable: You want a review sample that only describes a 50-piece box.
Specifications
Common questions
Is the 50-pack a different wheel from the 25-pack Craft-Line?
Both bullets use code C13081042, 125 x 1.0 x 22.23 mm and 12,250 rpm. This ASIN is the 50-pack at £20.90. The set name field says 40 UK.
Can the 8,013 reviews be read as a test of the 50-pack only?
No. The visible UK text matches the 25-pack listing and mentions both 25 discs and 50 pieces.
Does the listing claim stainless steel?
Yes. The bullets list stainless steel / INOX. They do not print an Fe-S-Cl limit. That limit is only on the Stone Reef listing in this set.
The Merryland C13081042-25 Craft-Line is a 25-pack of 125 x 1.0 x 22.23 mm cut-off wheels at £10.90, rated 4.6 from 8,007 reviews. The bullets claim two fibreglass layers, 12,250 rpm, EN 12413, an MPA mark, white corundum and a safety manual, and they list stainless steel as well as ordinary steel. The specification table also says ultra fine at grit 60 and 0.05 inches thick. The UK review blocks are the same texts as the 50-pack ASIN, including long-life praise, fast wear on sheet and exhaust, shards, and a finger-injury warning. One line on this 25-pack page talks about 50 pieces. It is the best value here if you want the printed 1.0 mm, 22.23 mm and 12,250 rpm line at a low pack price, and you do not treat 8,007 stars as a test of this box alone.
Pros
Cons
Best for: You want a low pack price on a 125 mm disc that prints bore, 1.0 mm and 12,250 rpm.
Less suitable: You need a review sample that only describes this 25-pack, or a single thickness figure.
Specifications
Common questions
What size grinder is this Craft-Line 25-pack for?
The bullets say a 125 mm (5 inch) angle grinder or cutting machine with a 22.23 mm bore, up to 12,250 rpm.
Does the page name stainless steel?
Yes. The bullets list stainless steel / INOX with steel, angle iron, sheet and pipe. They do not print an iron, sulphur and chlorine limit.
Are the 8,007 reviews only about this 25-pack?
The visible UK review text matches the Merryland 50-pack listing, and it mentions both 25 discs and 50 pieces. Treat the two star lines as one shared stream.
The Merryland B13081042-25 Bravo-Line is 25 discs at £12.90, specified in the bullets as 125 x 1.0 x 22.23 mm with two mesh layers, 12,250 rpm, EN 12413 and an MPA claim. The listing is rated 4.6 from 1,822 reviews. UK texts include long life on spring-steel spikes, cuts on scaffold poles, and a comparison with DeWalt. They also include quick wear, a disc used up on a steel barrel, and a warning that a thin disc can shatter. The construction field says Coated, the grit-material field lists metals rather than an abrasive, and one review is about a Makita grinder. Use it as a mid-price 1.0 mm 25-pack with rpm printed, and do not read the Coated field as a flap disc.
Pros
Cons
Best for: You want a 25-pack Bravo-Line disc with bore, 1.0 mm and 12,250 rpm printed.
Less suitable: You need a construction field that says bonded, or reviews with no shatter warning.
Specifications
Common questions
How is Bravo-Line described differently from a grinding wheel?
The bullets describe a 1.0 mm cut-off wheel at 12,250 rpm. The construction field says Coated, and one review says the discs are ideal for cutting and grinding. Do not grind on the face of a cutting disc.
Does this 25-pack name stainless steel?
Yes. The bullets list stainless steel / INOX with other metals and say code B13081042 is for universal use.
What do the UK reviews quarrel with?
Some praise life on spring steel and scaffold tube. Others say the discs wear quickly, and one warns that the thin disc can snag and shatter.
The Merryland E11081042 Expert-Line is a 25-pack at £14.90. The bullets say 125 x 1.0 x 22.23 mm, two mesh layers, 12,250 rpm, EN 12413, an MPA claim, and that the code is best for steel. The table says grit 180, medium, 5 inches, and 0.05 inches thick, and the recommended use includes grinding. The rank sits under Power Rotary Tool Cutting Wheels. The star line is 4.6 from 1,075, but only 10 UK texts are in the file: longer life than other discs, car bodywork, a Klingspor comparison, and a driver who threw the box over a gate. There is no repeated shatter note in those 10. Choose it only if you accept the grit clash and the thin review sample.
Pros
Cons
Best for: You want the Expert-Line steel wording and a printed 12,250 rpm, and you can ignore the grit-180 field until you see the disc.
Less suitable: You want grit, thickness and a review sample that all describe the same 1.0 mm wheel.
Specifications
Common questions
What is the Expert-Line pack for, on the listing?
The bullets say E11081042 is best for cutting steel, and they also list stainless steel, angle iron, sheet and pipe.
Why is grit 180 a problem on a cutting disc?
The specification field says grit 180, medium, while the bullets describe a 1.0 mm cut-off wheel. The page does not explain the clash.
How many UK reviews are actually in the file?
The star line says 1,075. The stored file contains 10 UK review blocks, nearly all short praise, plus one delivery complaint.
Stone Reef SR-1268 is listed at £12.99 as 25 discs, 125 x 1.0 x 22.23 mm, double fibreglass, a metal centre ring, EN 12413 and up to 12,200 rpm at 80 m/s. It is the only kept listing that prints Fe-S-Cl ≤ 0.1% and names V2A/V4A stainless. The same bullets say it fits 115 mm and 125 mm grinders, and the use line includes grinding and bevelling. Number of items is 1. It is rated 4.6 from 276 reviews, with nine UK texts: praise against Screwfix discs, one disc that started to disintegrate on steel, and a buyer who would have to take the guard off a 4.5 inch grinder. Use the Fe-S-Cl line only for this ASIN, and do not treat the 115 mm sentence as permission to run a 125 mm disc under a smaller guard.
Pros
Cons
Best for: You want the only pack in this set that prints an Fe-S-Cl limit, on a 125 mm grinder.
Less suitable: You run a 115 mm guard, or you want a page that does not also say grinding.
Specifications
Common questions
Which listing claims a low iron, sulphur and chlorine bond?
This one. The bullets say iron, sulphur and chlorine-free (Fe-S-Cl ≤ 0.1%) for stainless after cutting. That sentence is not on the other eight listings.
Will the page let you put it on a 115 mm grinder?
The bullets say it fits common 115 mm and 125 mm grinders. A UK review says it does not fit a 4.5 inch grinder unless the guard comes off. Do not remove the guard to force a 125 mm disc.
Is the use limited to cutting?
No. Recommended uses on the listing are metal cutting, grinding and bevelling. Do not grind on the face of a thin cut-off wheel.
Eclipse A60V125 is the cheapest pack in the set at £6.55 for 10. The title says 125 x 1.0 x 222.23 mm and names metal, ceramic, glass and composites. The tables say aluminium oxide, grit 60, bonded, diameter 125 mm, thickness 1 mm, and ANSI B7.1. There is no rpm. Weight is 140 g. The star line is 4.5 from 223. UK texts praise thin metal cuts and the tin, and they also describe guard rub, shatter if you angle the disc, a tin that is hard to open, expiry-date hunting, 100-packs and 115 mm model names. The low price is real. The bore figure on the title is not a usable 22.23 mm specification.
Pros
Cons
Best for: You want the lowest ten-pack price and you will check the metal ring for bore, rpm and expiry yourself.
Less suitable: You need EN 12413 and a 22.23 mm bore printed without a typo.
Specifications
Common questions
Is the bore 22.23 mm or 222.23 mm?
The title prints 125 x 1.0 x 222.23 mm. The specification tables have no bore row. Some reviewers write about 22.2 mm, which is not the title figure. Check the ring.
Which standard is on the listing?
The industry standard identifier is ANSI B7.1. EN 12413 is not printed, and maximum rpm is not printed.
Do the reviews match this 10-pack?
Some do. Others in the same file describe a 100-pack, a missing tin, or Eclipse A60V115. Read them as a mixed stream.
WojBear A005 is two 125 mm x 1.2 mm diamond cut-off wheels at £16.99. The bullets claim a 22 mm bore, a 20 mm reducer, 13,300 rpm, 80 m/s, dry cutting on steel, rebar, stainless, aluminium and brass, and life figures such as 5,000 cuts. They also say the disc fits standard 115 mm angle grinders. There is no EN 12413 line and no customer-review line. The recommended use includes metal grinding. Treat the life claims as seller copy. Do not mount a 125 mm disc in a 115 mm guard because the bullet says the bore fits.
Pros
Cons
Best for: You specifically want a diamond metal disc for a 125 mm grinder and you can check the bore on the wheel.
Less suitable: You want a bonded EN 12413 wheel with UK reviews, or a disc for a 115 mm guard.
Specifications
Common questions
Is this a resin-bonded cutting disc?
No. The construction field says super-abrasive and the grit material is diamond, on a claimed alloy steel core. EN 12413 is not printed.
What bore does the listing print?
22 mm, with a 20 mm reducer ring. It does not print 22.23 mm. Maximum speed in the table is 13,300 rpm.
Are the 5,000-cut claims reviewed?
They appear only in the seller bullets. The stored file has no star line and no UK review. Do not treat those life figures as measured UK data.
Nine amazon.co.uk listings were scored from the stored pages of 19 October 2026. Weights sum to 100. There was no lab test. The composites already on the product files run from 36 to 72. A 4.7 from 1,117 reviews is not scored like a 4.8 from 13, and a star line shared by two Merryland ASINs is not two samples. Würth’s UK catalogue figure of 12,250 rpm for a 125 × 1 mm steel disc at 80 m/s is a reference, not a speed measured on a grinder.
Listing fit
35%A stated 125 mm diameter, a bore near 22.23 mm, thickness, a metal claim that matches the job, a maximum rpm when one is printed, and EN 12413 on a bonded wheel. Missing bore or rpm, a 222.23 mm title bore, a 115 mm fit line, a grit field that fights the bullets, and an items field that fights the pack size are deductions.
Amazon evidence
25%Star rating and review count on amazon.co.uk. A 4.7 from 1,117 reviews sits above a 4.8 from 13. A line with no reviews scores at the bottom of this block. Two Merryland counts near 8,000 that share the same UK text are not treated as independent files.
Review outcome
25%UK themes that describe a finished cut on steel or stainless score higher than fast wear, a disc that rubs the guard, a shatter or disintegration note, or reviews that describe a different pack size or a different diameter.
Value
15%Shelf price in GBP against pack size and what the page actually prints. The block goes to the low pack price that still shows 1.0 mm, 22.23 mm and 12,250 rpm. The cheapest tin does not win it when the bore and the standard line fail.
The checks run in this order: guard and diameter, marked rpm, metal family, thickness, bonded or diamond, then pack price. The table is nine amazon.co.uk listings. A flap disc or a grinding wheel at 125 mm is a different product. No disc was spun in a lab. A star line shared by two ASINs is one stream.
A 125 mm metal cutting disc is a thin resin-bonded cut-off wheel for a 125 mm, 5 inch, angle grinder. The usual bore is 22.23 mm, which is 7/8 inch. A few listings are steel-body diamond wheels instead. You look at this category when you already own that grinder and you need to cut steel, stainless, tube, sheet or bolts. A tile blade, or a 115 mm disc, stays out of the table even if the bore matches. Work through the checks in this order. The guard has to be the 125 mm guard.
The bore can match while the disc is still too large. HAUTMEC, Stone Reef and WojBear mention 115 mm. Do not take the guard off to make the disc fit.
The Craft-Line 25-pack and the 50-pack share the same UK review text, including wear, shards and a finger-injury note. The 8,007 and 8,013 counts are one stream.
Organic bonded wheels for hand-held use carry a use-by date. THSP G712 notes three years. A cutting disc is not a grinding wheel. Side load and an expired disc are how thin wheels fail.
Use 125 mm on a 125 mm grinder. The usual bore is 22.23 mm. A 125 mm disc must not be forced onto a 115 mm guard, and a householder is not helped by a bullet that says the hole fits a smaller machine. DeWalt prints neither bore nor rpm. Eclipse prints 222.23 mm in the title and no rpm, with ANSI B7.1 rather than EN 12413. WojBear prints 22 mm, a 20 mm reducer and 13,300 rpm, and it is not an EN 12413 resin wheel. The Merryland packs and HAUTMEC print 22.23 mm and 12,250 rpm.
Aluminium oxide is the usual grain for steel. Titles that say INOX or stainless are the shortlist for stainless. Only Stone Reef prints Fe-S-Cl ≤ 0.1%, and that sentence stays on that ASIN. DeWalt is the named stainless ten-pack at 1.2 mm. The Merryland lines and HAUTMEC are 1.0 mm in the bullets. Craft-Line 25 and Expert-Line also show 0.05 inches in a table, so the thickness is not a single figure. Thinner cuts faster and side-loads more easily. Eight listings are bonded wheels.
Three typical situations, each with a recommendation from this comparison.
You want a DeWalt 125 mm stainless ten-pack and you can read the disc itself for bore, rpm and expiry. The DT42340TZ is £9.99, 1.2 mm, with EN 12413 on the listing and 4.7 from 1,117 reviews. One UK review reports a first-use disintegration, and the page does not print rpm.
You want bore, 1.0 mm and 12,250 rpm on the page, at a low pack price. The Merryland Craft-Line 25-pack is £10.90 and names stainless as well as steel. The 4.6 from 8,007 reviews is the same text as the 50-pack, and the thickness table says 0.05 inches.
You want the only pack in this set that prints an Fe-S-Cl limit, on a 125 mm grinder. Stone Reef SR-1268 is £12.99 for a stated 25, with 12,200 rpm, EN 12413 and 4.6 from 276 reviews. The bullets also claim 115 mm grinders and grinding.
The top pick is the DeWalt DT42340TZ, ten flat 125 x 1.2 mm stainless discs at £9.99, with EN 12413 on the listing and 4.7 from 1,117 reviews. Bore and maximum rpm are not printed, the items field says 1, and one UK review reports a disc disintegrating on first use. The best value is the Merryland Craft-Line 25-pack at £10.90, with 125 x 1.0 x 22.23 mm, 12,250 rpm and EN 12413 in the bullets. Those 8,007 reviews match the 50-pack text, the thickness table says 0.05 inches, and the shared notes include fast wear and a finger-injury claim. A 4.8 from 13 ratings is not the top score. Eclipse is the lowest pack price at £6.55 and stays off both awards because the title bore is 222.23 mm and rpm is missing.
Merryland Craft-Line discs (25)
Printed 125 x 1.0 x 22.23 mm, 12,250 rpm and EN 12413 at £10.90 for 25. The 8,007 reviews match the 50-pack text, the thickness field says 0.05 inches, and that shared text includes fast wear and injury claims.
