The best cutting discs, compared.
Top pick: Starrett 115 × 1 mm, 12-pack – Tied on score with MIDO, and chosen because the listing has one thickness figure and the larger review file: 4.7 from 527, 115 × 1 × 22.23 mm, EN 12413. Best value: Merryland 115 × 1.0 mm, 50-pack – Lowest calculated price per disc among bonded 115 mm wheels that print both a maximum rpm and EN 12413, at about 38p, after the top pick is already used. Updated October 2026.
A cutting disc is a consumable for a UK angle grinder you already own. Eleven of the twelve amazon.co.uk listings are resin-bonded cut-off wheels. One listing is a diamond blade, and the disc is a single 230 × 3 mm wheel. You need a diameter that matches the guard, a bore that matches the spindle, and a marked speed at or above the grinder. The usual hole is 22.23 mm on 115 mm, 125 mm and 230 mm discs, so a larger wheel can be forced on. Quality means that match, a thickness for the cut, a named metal, and a readable EN 12413 mark on bonded wheels. A disc that claims steel, tile and wood is not a 1 mm inox wheel. Those checks, in order, are on the [cutting disc buying guide](/hub/sanders/cutting-disc/sub/cutting-disc-buying-guide). That usually means a thin resin-bonded cut-off wheel, sometimes a diamond blade sold under the same search. UK shoppers are matching a 115 mm, 125 mm or 230 mm guard, not choosing a grinder. Do not remove the guard to make it fit.

Personal buying guide
Question 1 of 2
Which guard is on the grinder?
The Starrett DAC115-14X is twelve 115 × 1 × 22.23 mm aluminium-oxide discs at £5.03, about 42p each, rated 4.7 from 527 amazon.co.uk reviews. UK reviewers describe clean cuts in stainless, mild steel and plastic, including a 10 mm bolt in seconds and about ten cuts in steel tube from one disc. The listing says the wheels are double reinforced, grit 46, and made to EN 12413. Maximum rpm is not printed, so the figure on the disc still has to meet the grinder. One UK review says two of three thin discs shattered after kickback, which is the limit of a 1 mm wheel when the cut pinches. For a small 115 mm pack with a readable standard and a UK review file, this is the top pick, and only for a straight cut with the guard on.
Pros
Cons
Best for: You run a 115 mm grinder and want a small EN 12413 pack for steel, stainless and plastic.
Less suitable: You need a printed maximum rpm before you order, or a 125 mm or 230 mm wheel.
Specifications
Common questions
Which grinder does this Starrett pack fit?
The listing says 115 mm discs with a 22.23 mm bore for cordless, corded and air-powered angle grinders. Maximum rpm is not printed, so check the figure on the disc against the grinder.
What can these discs cut?
The listing names stainless steel, carbon steels, iron, aluminium, other ferrous and non-ferrous metals, and plastics. Recommended use is cutting, in a straight line, with the guard on.
Is a safety standard printed?
Yes. The listing says the discs are manufactured to EN 12413 – NBR15230. A use-by date is not printed on the listing we stored.
The MIDO K101 is a 25-pack for 115 mm grinders at £13.99, rated 4.7 from 414 reviews, with 13,300 rpm and EN 12413 stated. UK reviews describe a thin, fast cut on vehicle bodywork and mild steel plate. Thickness is not one figure: bullets say 1 mm and 0.045 inch (1.2 mm), and the spec line says 0.05 inches. The bore is printed as 22.2 mm and also as 22.23 mm. In the UK sample the first disc snapped for one reviewer, another calls the discs flimsy, and another says the bore was the wrong size. The star line matches the top of this set, and the listing still does not settle how thick the disc is.
Pros
Cons
Best for: You will measure the disc in the box against 1 mm and 22.23 mm before you fit it.
Less suitable: You need the listing itself to agree on thickness and bore.
Specifications
Common questions
How thick is this MIDO disc?
The listing does not settle it. Bullets say 1 mm and 0.045 inch (1.2 mm). The spec line says 0.05 inches. Measure the disc before you fit it.
Which grinder is it for?
The listing says 4.5 inch (115 mm) angle grinders and a 7/8 inch arbor, up to 13,300 rpm. The bore is printed as both 22.2 mm and 22.23 mm.
What standard is printed?
The bullets say the discs comply with EN 12413. That is the mark on the listing, not a certificate inspected for this page.
The Merryland C13071042-50 is fifty 115 × 1.0 × 22.23 mm wheels at £18.90, about 38p a disc, the lowest calculated unit price here among bonded 115 mm wheels that print both a speed and EN 12413. The listing states 13,300 rpm, two fibreglass layers, calcined and white corundum, and a safety manual in the box. The star line is 4.6 from 8,013 reviews, and that block is shared with the other two Merryland ASINs. Shared UK texts describe many cuts in 5 mm flat bar and tube, and one reviewer prefers the life to Würth, DeWalt, Bosch and Erbauer. Another says life is shorter than mainstream workshop discs, and one reports fragments in a forearm. That unit price is why this is the best value, with the shared reviews already counted against it.
Pros
Cons
Best for: You already own a 115 mm grinder and you will work through a large pack of 1 mm metal discs.
Less suitable: You want a review count that belongs only to this ASIN, or a stated stainless contamination limit.
Specifications
Common questions
What size of angle grinder is this 50-pack for?
The listing says a 115 mm (4.5 inch) angle grinder or cutting machine with a 22.23 mm bore, up to 13,300 rpm. It is the wrong diameter for a 125 mm or 230 mm guard.
Does the box include instructions?
The listing says a safety manual is in the box with the 50 discs. The manual does not replace the guard, the marked speed, or a straight cut.
Are the 8,013 reviews unique to this pack?
No. The stored review notes say the visible review texts and the 8,013 count match the other two Merryland ASINs in this category. Treat them as one shared block.
The Merryland C13081042-50 is fifty 125 × 1.0 × 22.23 mm wheels at £20.90, about 42p a disc, with a stated 12,250 rpm, EN 12413, two fibreglass layers and aluminium oxide. The listing specifies a 125 mm grinder and names stainless, steel, angle iron, sheet, plastic and pipe. The star line is 4.6 from 8,013, and the stored notes say those texts match the 115 mm Merryland packs and do not distinguish 125 mm. One shared review mentions a 25-disc pack, which is not this box, and the same block includes fragments during cutting. Grit is printed as 60, coarse, and the pack weighs 1,600 g. Buy it when the guard is already 125 mm.
Pros
Cons
Best for: Your grinder and guard are 125 mm and you want a bulk 1 mm metal pack with a printed speed.
Less suitable: You own a 115 mm grinder, or you need reviews that are only about this diameter.
Specifications
Common questions
Will this 125 mm pack fit a 115 mm grinder?
The listing specifies a 125 mm (5 inch) grinder and a 22.23 mm bore. It does not say the disc fits a 115 mm guard. Do not take the guard off to force it on.
What is the maximum speed?
12,250 rpm, with EN 12413 named on the listing. That speed has to be at least the speed marked on your grinder.
Are the reviews only about this 125 mm disc?
No. The stored notes say the visible reviews and the 8,013 count match the other Merryland ASINs and do not distinguish 125 mm.
The Merryland C13071042-25 is twenty-five 115 × 1.0 × 22.23 mm discs at £9.90, about 40p each, with 13,300 rpm, EN 12413 and a safety manual in the box. The spec line also prints 1.14 mm against the 1.0 mm bullet. The star line is the same shared 4.6 from 8,013 as the Merryland 50-packs. One shared review mentions 25 discs, which matches this box, and the same block includes long life on flat bar and tube plus a report of shards. Grit is 60, aluminium oxide, two fibreglass layers, and the pack weighs 710 g. It is the smaller Merryland option for a 115 mm grinder, with the thickness line left as printed.
Pros
Cons
Best for: You want twenty-five 115 mm discs rather than fifty, and you will check the thickness on the disc.
Less suitable: You need a unique review file or a single thickness figure in the listing.
Specifications
Common questions
How is this 25-pack different from the Merryland 50-pack?
The listing shows the same 115 mm diameter, 22.23 mm bore and 13,300 rpm, with 25 discs at £9.90. The spec line also prints thickness 1.14 mm against a 1.0 mm bullet.
Is a manual included?
The listing says a safety manual is in the box. It does not replace the guard or the speed marked on the disc.
Is the review count unique?
No. The stored notes say the 4.6 from 8,013 reviews matches the other Merryland ASINs in this category. It is one shared block.
The TechZone pack, code AS60W, is ten 115 × 0.8 mm slitting discs at £5.99, rated 4.6 from 4,954 reviews, with 13,300 rpm and EN 12413 stated for stainless, mild steel and iron. In the UK sample, one disc cut about 3 m of 2 mm galvanised sheet, and reviewers also used them on a car exhaust. The same sample says the first disc broke in the middle, barely used, on metal handrail brackets. The bore is not stated, and reinforcement is not in the comparison fields. Grit is 60 and the pack weighs 200 g. At 0.8 mm this is the thinnest wheel in the set, which suits a narrow kerf on sheet and leaves less disc if the cut twists.
Pros
Cons
Best for: You cut thin galvanised sheet or light steel on a 115 mm grinder and you will check the bore on the disc.
Less suitable: You cut thicker bar, or you need the hole size in the listing before you order.
Specifications
Common questions
How thin is this pack?
The listing says 115 × 0.8 mm. The bore is not stated. At 0.8 mm it is the thinnest wheel in this set, so a twisted cut has less disc to spare.
What is the speed and standard?
Maximum 13,300 rpm, with EN 12413 and the code AS60W printed. The marked speed still has to meet the grinder.
Which metals are named?
Stainless steel, mild steel and iron. Recommended use is cutting. A UK review also describes an exhaust and about 3 m of 2 mm galvanised sheet.
The WORKPRO W124620A is twenty 115 × 1.2 mm discs at £12.55, rated 4.6 from 4,859 reviews. The UK sample praises life on thin steel and also reports centres that broke up. The bullet says up to 13,300 rpm and 80 m/s, while the spec table says 13,000 rpm, and the bore on the listing is 22 mm. EN 12413 is not printed. Grit is 36, with double fibreglass mesh, and the materials named are stainless, carbon steel, iron, copper, pipes and tubes. You get a slightly thicker wheel and a large review count, and you still have two speed figures to reconcile on the disc itself.
Pros
Cons
Best for: You want a 1.2 mm 115 mm pack and you will read the speed and the bore on the disc, not only the bullet.
Less suitable: You need EN 12413 in the listing, or a bore stated as 22.23 mm.
Specifications
Common questions
Is EN 12413 printed for this WORKPRO pack?
No. The safety mark is not printed. The bullets do say to wear protection, not to exceed the rated speed, and to secure the work.
What bore does the listing give?
The bullet says a 22 mm arbor, 115 mm diameter and 1.2 mm thickness. That is not written as 22.23 mm.
Which speed figure is printed?
Both, and they disagree. The spec table says 13,000 rpm. The bullet says up to 13,300 rpm and 80 m/s. Read the disc before you fit it.
The Bosch 2608603162 is one depressed-centre metal cutting disc at 230 × 3 × 22.23 mm, listed at £2.41, with 4.6 from 1,253 reviews. Twenty-nine of the first fifty review texts are from the United Kingdom, and they split between a disc that lasts a bit longer than cheap discs and a disc that feels used up after a single cut. The title includes oSa. Maximum rpm and EN 12413 are not printed, grit is 80, and the dimension field prints 0.1 cm against a stated 3 mm disc. Amazon’s browse line files it under grinding discs, while the title says a cutting disc for a large grinder. It is the only 230 mm wheel in the set, and it does not replace a 115 mm or 125 mm pack.
Pros
Cons
Best for: You run a 230 mm grinder and you want one metal cutting disc rather than a small-grinder pack.
Less suitable: You own a 115 mm or 125 mm grinder, or you need a printed maximum rpm.
Specifications
Common questions
Which grinder is this Bosch disc for?
The listing says a 230 × 3 × 22.23 mm disc for large angle grinders with a 22.23 mm locking-nut bore. It is one disc. It does not replace a 115 mm or 125 mm pack.
Is a maximum rpm printed?
No. Maximum rpm and EN 12413 are not printed. The title includes oSa. Read the speed on the disc before you fit it.
Why does Amazon file it under grinding discs?
The best-sellers line says Grinding Discs. The title and scope of delivery say a metal cutting disc with a depressed centre. Treat it as a cutting disc for a 230 mm grinder.
The Metabo 616358000 is a tin of ten A 60-R inox discs, 115 × 1.0 × 22.23 mm, at £4.95, the lowest box price for a 115 mm pack in this set. The bullets state iron, sulphur and chlorine at or below 0.1 percent, which no other listing here prints, and the maximum speed is 13,200 rpm. EN 12413 is not in the safety field, which repeats the model number. The star line is 4.6 from 465. The fifty written review texts are from other Amazon marketplaces, so they are not used as UK opinion, though one of those notes says a nominal 1 mm disc often measures thicker. For stainless where that contamination figure has to be on the listing, this is the pack that states it.
Pros
Cons
Best for: You cut stainless on a 115 mm grinder and you want the contamination limit in the listing.
Less suitable: You need EN 12413 on the page, or UK review texts rather than the star line alone.
Specifications
Common questions
Does this Metabo pack state a stainless contamination limit?
Yes. The bullets say iron, sulphur and chlorine at or below 0.1 percent. That figure is not printed on the other listings in this set. Do not copy it onto them.
Is EN 12413 on this listing?
No. The industry-standard field repeats the model number 616358000. Maximum speed printed is 13,200 rpm. Size is 115 × 1.0 × 22.23 mm, class A 60-R, TF 41, tin of 10.
Are the written reviews from the UK?
The 4.6 from 465 is the listing line. The 50 written review texts are from other Amazon marketplaces, not the United Kingdom, so they are not used as UK opinion.
The STONE REEF SR-1268 is twenty-five 125 × 1.0 × 22.23 mm aluminium-oxide discs at £12.99, rated 4.6 from 276 reviews. The listing states 12,200 rpm, 80 m/s, EN 12413 and double-layer fibreglass, for stainless including V2A and V4A, carbon steel and sheet, with no iron, sulphur and chlorine limit. UK reviews praise life against a budget Screwfix equivalent and a clean cut at the price. A bullet says the discs suit 115 mm and 125 mm grinders. A UK review says they do not fit a 4.5 inch grinder unless the guard comes off, and another says a disc started to disintegrate while cutting steel. Leave the guard on. This pack belongs on a 125 mm grinder.
Pros
Cons
Best for: You have a 125 mm guard and you want a 25-pack that names stainless grades.
Less suitable: You own a 115 mm grinder, or you would take the guard off to force a fit.
Specifications
Common questions
Can this 125 mm disc go on a 115 mm grinder?
The bullet says common 115 mm and 125 mm grinders. A UK review says they do not fit a 4.5 inch grinder without taking the guard off. Do not remove the guard to fit them.
What speed is printed?
12,200 rpm and 80 m/s, with EN 12413 named on the listing. The marked speed has to be at least the speed on the grinder.
What metals does the listing name?
Stainless steel, including V2A and V4A, carbon steel and sheet metal. It does not state an iron, sulphur and chlorine limit. Only the Metabo listing in this set prints that figure.
The Faithfull FAI11510MUL is ten 115 × 1 × 22.23 mm discs in a metal tin at £6.95, rated 4.5 from 662 reviews. The listing is a multi-cut for sheet metal, stainless and pipes, and also brick, stone, ceramic, plastics and PVC, with EN 12413 named. Maximum rpm is not printed, and the item weight of 60 g is not a plausible weight for a ten-disc tin. UK reviews describe cuts in 1.6 mm sills, 2 mm plate, 20 mm round bar and drop-link bolts on a Makita grinder. The same sample says the first disc went ragged on a long sheet cut, that wear is quick, and that the disc can break if it is forced. A tin that lists masonry and metal together is a different product from a dedicated steel wheel.
Pros
Cons
Best for: You want a small tin whose listing also names tile, plastic and light metal, and you will read the speed on the disc.
Less suitable: You need a printed rpm, or a disc sold only for steel and stainless.
Specifications
Common questions
Is this only a metal disc?
No. The listing also names brick, stone, ceramic tiles, plastics and PVC, as well as sheet metal, stainless steel, pipes and profiles. It is not a dedicated 1 mm inox wheel.
What comes in the box?
Ten 115 × 1.0 × 22.23 mm discs in a metal storage tin. The printed item weight of 60 g is not a plausible weight for that tin.
Is a maximum rpm printed?
No. Maximum rpm is not printed. EN 12413 is named as the industry standard. Read the speed on the disc before you fit it.
The Lozlin set, with Penfuzon in the brand field and model Penpon040, is three 115 mm diamond blades at £9.79, not a resin cut-off wheel. The title lists concrete, steel, PVC, granite and marble, and a spec line also mentions wood. Thickness is printed as both 1 cm and 0.1 cm, and EN 12413, maximum rpm and the bore are absent. The only amazon.co.uk review scores 1.0 and says an M10 low-carbon screw took about seven minutes, against 38 seconds with a hacksaw. One review does not test tile or concrete. It is enough to leave this set off a shortlist for steel bolts.
Pros
Cons
Best for: You already know you want a diamond blade and you will wait for more than one UK review before you rely on this listing.
Less suitable: You need a thin bonded disc for a steel bolt or a clean stainless edge.
Specifications
Common questions
Is this a thin metal cut-off wheel?
No. The title says three diamond blades for concrete, steel, PVC, granite and marble, dry and wet. EN 12413 and maximum rpm are not printed. It is not a 1 mm bonded wheel.
Which brand name is on the listing?
The brand and manufacturer fields say Penfuzon. The title and set name say Lozlin. The model line is Penpon040.
What does the only review say?
One UK review rates it 1.0 and says an M10 low-carbon screw took about seven minutes, against 38 seconds with a hacksaw. One review does not test tile or concrete.
Twelve amazon.co.uk listings were scored for this page. Weights sum to 100. The scores were already on the display rows, and the two badges were chosen from those scores. There was no lab test. An EN 12413 line is the mark printed on that listing, not a certificate we inspected. Shelf prices are the stored figures from 19 October 2026.

A cutting disc here is a consumable for an angle grinder you already own. In this set that usually means a thin resin-bonded cut-off wheel, sometimes a diamond blade sold under the same search. UK shoppers are matching a 115 mm, 125 mm or 230 mm guard, not choosing a grinder. The usual bore is 22.23 mm on all three sizes, so a larger disc can be forced onto a smaller spindle. That is not a fit. Do not remove the guard to make it fit.
A 125 mm disc can sit on a 115 mm spindle and still not fit the guard. A UK review of STONE REEF says the guard has to come off. Leave the guard on.
A cutting disc cuts in a straight line. Side load is how a thin wheel twists and shatters. A grinding disc is the thicker wheel used at an angle.
A 50-pack is poor value on the wrong diameter. Metabo is the lowest 115 mm box price and still does not print EN 12413. Lozlin is £9.79 with one review at 1.0.
115 mm, 125 mm and 230 mm are the sizes that matter here. The usual bore is 22.23 mm, which is why an oversized disc can be forced on. WORKPRO prints 22 mm. MIDO prints 22.2 mm and 22.23 mm. TechZone and the Lozlin blades do not state a bore. Marked maximum rpm must be at least the grinder. Printed 115 mm speeds in this set sit at about 13,300 rpm, or 13,200 rpm on the Metabo inox pack. Printed 125 mm speeds sit at 12,250 rpm (Merryland) and 12,200 rpm (STONE REEF).
Aluminium oxide is the usual grain for steel. A disc labelled inox or stainless is the shortlist for stainless. Only Metabo states Fe + S + Cl ≤ 0.1%. STONE REEF names V2A and V4A and does not print that limit. Faithfull also names brick, stone, ceramic and plastic. Lozlin is three diamond blades, with one UK review of about seven minutes on an M10 screw. About 0.8–1.2 mm suits sheet, tube and bolts on a small grinder. TechZone is 0.8 mm. WORKPRO is 1.2 mm.
Three typical situations, each with a recommendation from this comparison.
You cut bolts and brackets at home and you want a 10- or 12-pack, not a crate. The Starrett pack is twelve 115 × 1 × 22.23 mm discs at £5.03, with 4.7 from 527 reviews and EN 12413. Maximum rpm is not printed, so read it on the disc.
You will work through thin steel and you care about price per disc after the guard is already 115 mm. The Merryland 50-pack is £18.90, about 38p a disc, with 13,300 rpm and EN 12413. The 8,013-review line is shared with the other Merryland ASINs.
You want a small tin whose listing also names brick, ceramic and plastic. The Faithfull pack is ten 115 × 1 mm discs at £6.95, with EN 12413 and no printed rpm. UK reviews include rapid wear and breakage if the disc is forced. The Lozlin diamond set is the one to skip for a steel bolt.
The top pick is the Starrett 12-pack at £5.03, 115 × 1 × 22.23 mm, with 4.7 from 527 reviews and EN 12413 printed. It ties on score with the MIDO 25-pack and takes the badge because the thickness is a single figure and the review file is larger. Maximum rpm is not printed, and a UK review reports shatter after kickback. The best value is the Merryland 115 mm 50-pack at £18.90, about 38p a disc, with 13,300 rpm and EN 12413. Its 4.6 from 8,013 reviews is shared with the other Merryland ASINs, so that block is not three separate studies.
Starrett 115 × 1 mm, 12-pack
Tied on score with MIDO, and chosen because the listing has one thickness figure and the larger review file: 4.7 from 527, 115 × 1 × 22.23 mm, EN 12413.
Merryland 115 × 1.0 mm, 50-pack
Lowest calculated price per disc among bonded 115 mm wheels that print both a maximum rpm and EN 12413, at about 38p, after the top pick is already used.
