The best milling cutter sets, compared.
Top pick: Genmitsu MRBC08 8-piece CNC bit set, 1/4 inch Best value: ASNOMY 10-piece HSS end mill set, 2-12 mm – Same top score at about £14.24, with centre cutting stated and 4.5 from 1,595 reviews. Updated October 2026.
A milling cutter set on amazon.co.uk is three tools in one search: a metric HSS end-mill pack for a milling machine, a small-shank carbide pack for a desktop, and a rail-and-stile pair for a router. A 1/4 inch collet is 6.35 mm, not 6 mm, so most of a 2–12 mm end-mill set will not go in a UK handheld router. Stars on the cheap HSS sets are about 4.4 to 4.5, and the reviews mostly support light aluminium, not the full material list. The [milling cutter set buying guide](/hub/routers/milling-cutter-set/sub/milling-cutter-set-buying-guide) names the machine and the shank before the price. In the listings for this comparison, three families share the search phrase.

Personal buying guide
Question 1 of 2
Which machine will hold the cutter?
The SainSmart Genmitsu MRBC08 is eight mixed CNC profiles on a 1/4 inch (6.35 mm) shank at £93.99. The set includes tapered bits, a ball nose, up and down spirals, a 60 degree V, a 90 degree V, an O-flute, and a 2-flute. A bullet says tungsten steel, a nano blue coating, and 60-70 HRC, while the finish attribute says TiAlN, and individual profile diameters are not listed. No storage case is named, and the printed weight is 200 g. Amazon.co.uk shows 4.8 from 8 reviews, with three texts in the capture and none marked United Kingdom. One German review says a downcut cut wood and also went through an aluminium clamp by mistake, and that inch sizes were awkward. Two of those three reviewers had not tried every profile.
Pros
Cons
Best for: A desktop CNC with a 1/4 inch collet when you want several profiles in one box.
Less suitable: A metric milling machine, or a choice that needs a large UK review sample.
Specifications
Common questions
Will it fit a 6 mm collet?
No. The shank is 1/4 inch, 6.35 mm. The bullet says to match the collet.
What coating is named?
The bullets say nano blue. The finish attribute says TiAlN. Both are printed. Hardness 60-70 HRC is a bullet claim.
How many UK reviews are in the capture?
None of the three texts is marked United Kingdom. The listing score is 4.8 from 8.
The AFUNTA AF-4-flute_end_mill_10 is ten HSS mills from 2 mm to 12 mm at £16.99, for a milling machine or CNC rather than a handheld router. Amazon.co.uk shows 4.5 from 2,455 reviews, the largest count in this comparison, and the first 50 texts are mostly from the United Kingdom. Reviewers often report a clean edge on aluminium, brass, and careful mild-steel cuts, and some say the edge holds after a light grind. The same sample includes boxes with a 2-flute and a 3-flute among mills sold as 4-flute, plus burrs, rust, and one empty box. Centre cutting is not stated, and the printed item weight is 20 g. It is the top pick on review volume, as long as you check flute count and the cutting edge before the first job.
Pros
Cons
Best for: A cheap jobbing set for light aluminium, brass, and careful mild steel, if you inspect each cutter.
Less suitable: A guaranteed four-flute centre-cutting mill straight out of the box, or a handheld router.
Specifications
Common questions
Are all ten pieces four-flute?
The listing says four flutes. UK reviews include a 2-flute and a 3-flute in the same box, and a mix of plunge and non-plunge ends.
Can I plunge with them?
Centre cutting is not stated. Do not assume a plunge from the flute count.
What went wrong in reviews?
Regrinding before use, burrs, rust, quick dulling on mild steel, and one empty box. Many other reviews were satisfied with light cuts.
The ASNOMY AS0087 is ten 4-flute HSS end mills from 2 mm to 12 mm, including 7 mm and 9 mm, for milling-machine and CNC work at £14.24. Centre cutting is stated, the HSS grade is not named, and the printed pack weight is 270 g. On amazon.co.uk the listing sits at 4.5 from 1,595 reviews, and the first 50 are mostly from the United Kingdom. Those reviews mostly describe a usable finish on aluminium, nylon, plastics, and the flat bottom of a drilled hole. A UK review says the set would not cut cast iron, and a non-UK review found steel blunted quickly while plastic and aluminium stayed acceptable. The bullets do not list a case, one review says these are not slot drills, and at this price with that review sample it is the best value here if you stay on aluminium and look at the edge before a harder metal.
Pros
Cons
Best for: Light aluminium, nylon, and plastics on a milling machine or CNC, when you want a cheap 2 mm to 12 mm range.
Less suitable: Cast iron, titanium, a slot drill, or a handheld router.
Specifications
Common questions
Does the listing say these are centre cutting?
Yes. The listing attribute is End cut type Center. One UK review still says they are end mills, not slot drills.
What did UK reviews cut?
Most of the first 50 reviews praise aluminium and light hobby cuts. Cast iron and steel drew failures in a minority of reviews.
Is a case included?
The bullets do not list a case. Reviewers describe individual cases and labels.
The HSEAMALL SUP80 is ten HSS 4-flute mills from 2 mm to 12 mm, supplied with a blue plastic case, at £15.99. The listing calls the tip a square end, prints a 35 mm cutting-length attribute and a 0.2 mm corner radius, and does not state centre cutting. The HSS grade is not named, and the pack weight is printed as 200 g. Amazon.co.uk shows 4.5 from 9 reviews, and the capture has four texts, two from the United Kingdom and two from Germany. One UK review says the large size clogged on a deeper cut, while a German review reports work on mild steel and other soft metals. Nine reviews are too few to treat that steel result as typical.
Pros
Cons
Best for: A cased 2 mm to 12 mm HSS set when a sample of nine reviews is enough for you.
Less suitable: A four-flute mill you want to trust in steel on the back of hundreds of UK reviews.
Specifications
Common questions
Is a case included?
Yes. The bullets and the included-components line name a storage case.
Can I drill with them?
A bullet says milling, drilling, and cutting. Centre cutting is not stated, so a plunge is not confirmed.
What did reviews say?
Four texts. One UK review says the large size clogged in deeper stock. A German review says mild steel and soft metals were fine.
The Oudtinz set is eight 4-flute mills at £16.99, in 2, 3, 4, 5, 6, 8, 10, and 12 mm, so 7 mm and 9 mm are not included. Centre cutting is stated, the printed weight is 200 g, and a single cutting-length attribute reads 8 mm. Amazon.co.uk shows 4.4 from 921 reviews. Of the first 50 texts, ten are marked United Kingdom, and buyers describe light cuts in mild steel, aluminium, and brass. The title says high-speed steel while a bullet says tungsten steel, and the printed inch table does not equal the millimetre sizes. Reviews also mention dulling or a chip after one steel cut, rust on the tips, and metric cutters in packaging that suggested imperial sizes.
Pros
Cons
Best for: Eight metric sizes for light non-ferrous work, if you measure the cutters and ignore the inch table.
Less suitable: A known carbide grade, true inch shanks, or the missing 7 mm and 9 mm sizes.
Specifications
Common questions
Is it HSS or tungsten?
Both appear on the listing. The title and material line say high-speed steel. A bullet says ultra-fine tungsten steel. The listing does not resolve it.
Are the inch sizes right?
No. The bullet sets 1/16 inch equal to 2 mm and 1/2 inch equal to 12 mm. Reviews say the cutters are metric.
Do reviews support steel?
Some UK reviews say mild steel, aluminium, and brass were fine if the cut was light. Other reviews say the edge died on the first steel cut.
The Hozly DRZXQ3*22 is five identical solid-carbide downcut O-flute bits, all on a 1/8 inch (3.175 mm) shank, at £16.99. Cutting length is 22 mm. Overall length is 38 mm in one line and 45 mm in the size name, and the printed weight is 40 g. Amazon.co.uk shows 4.4 from 251 reviews. Reviewers describe a clean top edge on ply, MDF, poplar, and acrylic, including on a small 3018-style CNC, and they treat the five bits as spares when one snaps. A UK review on maple reports packed chips and smoke, and other texts describe snaps when the feed, the step, or a leftover plug catches the tool. Only three of the first 50 reviews are marked United Kingdom.
Pros
Cons
Best for: Backup downcuts for a 3.175 mm CNC collet on sheet goods and plastics.
Less suitable: Several diameters, a milling-machine end mill, or hardwood slots where chips must clear.
Specifications
Common questions
Is this a mixed milling cutter set?
No. It is five copies of one 1/8 inch downcut. You get spares, not a size range.
What shank does it need?
1/8 inch, 3.175 mm. It does not fit a 6 mm or 1/4 inch collet.
Why do reviews mention smoke and snaps?
The bullet says a downcut packs chips and that you should slow the feed. A UK review saw smoke in maple. Other reviews report easy breakage.
The QWORK WD45769 lists ten 4-flute end mills in named HSS4241, from 2 mm to 12 mm, at £13.99. That is the lowest price in this comparison, and the printed weight is 215 g. The bullets describe a straight shank for profiling, shoulder milling, and finishing, and they name wood, aluminium, and steel. The end is given as flat, centre cutting is not stated, and no storage case is listed. The amazon.co.uk capture has no customer-review line and no review texts, so there is no star rating for edge life or for whether the flutes match the listing. You are buying the grade name and the size list, then checking the cutters yourself.
Pros
Cons
Best for: A listing that names HSS4241, if you will inspect the mills before use.
Less suitable: Anyone who wants review evidence, a stated centre cut, or a handheld router bit.
Specifications
Common questions
What steel grade is named?
The bullets say HSS4241. No other HSS set in this comparison names a grade.
Is there a review count?
No. The amazon.co.uk capture has no customer-review line.
Does it include a case?
Not stated.
The Socoje Router Bits Sets-002 is two rail and stile cutters with a 1/2 inch shank, at £21.99, for door and window frames on a router. The listing states 45# carbon steel, one flute, a round-over cut, and an enclosed lubricated bearing. A heat-resistant coating is claimed, with no coating name, and the printed weight is 360 g. Cutting diameter and maximum speed are not stated, and no case is listed. The amazon.co.uk capture has no customer-review line and no review texts, so there is no report of how the edge behaves in hardwood. This is a woodworking pair for a 1/2 inch collet, not an HSS or carbide end mill for metal.
Pros
Cons
Best for: Wooden door or window frames on a router that has a 1/2 inch collet.
Less suitable: Metal milling, or a router that only takes a 1/4 inch collet.
Specifications
Common questions
Is this an end mill set?
No. It is two rail and stile router bits for wood frames. The shank is 1/2 inch.
What is it made from?
The bullets say 45# carbon steel with a heat-resistant coating. They do not say HSS or carbide.
Are there reviews?
No review line on the amazon.co.uk capture.
Eight milling cutter sets are on this page. Scores use the amazon.co.uk listing fields and the review lines already captured for each ASIN. There is no laboratory test. Review evidence is 45 points, and a large sample outweighs a high star line on a handful of reviews. Listing clarity and fitness for the stated machine are 25 points. Repeated review complaints are 20 points, taken off when they appear in the same sample. Price against the pack is 10 points. A low price with no reviews does not collect that. A listing with no customer-review line scores 0. Under 10 reviews, the star line can stay high and the score stays off both badges.

Name the machine before you compare stars. A metric HSS end-mill pack, a small-shank CNC bit, and a rail-and-stile pair are different purchases. Prices on this page are amazon.co.uk listings, from about £13.99 to about £93.99.
A milling cutter set on amazon.co.uk is not one tool. In the listings for this comparison, three families share the search phrase. The first is a metric high-speed-steel end-mill pack for a milling machine or a mill-drill. QWORK, ASNOMY, HSEAMALL, AFUNTA, and Oudtinz are that family, from about £13.99 to £16.99. The second is a small-shank carbide or coated bit pack for a desktop CNC. Hozly is five identical 3.175 mm solid-carbide downcuts at about £16.99.
A 1/4 inch collet is 6.35 mm, not 6 mm, and 12 mm is not 1/2 inch. Most of a 2–12 mm end-mill set will not go in a UK handheld router. Router bits are not end mills.
Four flutes do not prove centre cutting. ASNOMY states Center. AFUNTA, QWORK, and HSEAMALL do not. If the set cannot plunge, add a slot drill.
Reviews on the cheap HSS sets mostly describe light aluminium. Oudtinz prints both HSS and tungsten steel. Only QWORK names HSS4241, and that listing has no reviews. Do not call the others M2.
Name the machine before you compare stars. A mill, a mill-drill, a desktop CNC, and a handheld or table router do not take the same cutter. The shank has to match the collet. Common UK router collets are 1/4 inch, which is 6.35 mm, and 1/2 inch, which is 12.7 mm. Desktop CNCs in this comparison use 3.175 mm or 1/4 inch. Metric end mills step with the cutting diameter, and several listings do not state the shank for each size. A 2–12 mm HSS set is for a milling machine.
Read the material line against the reviews. The cheap HSS sets print long material lists. The reviews mostly support light cuts in aluminium, and sometimes brass, nylon, plastics, or careful mild steel. They do not confirm stainless, titanium, or cast iron. Only QWORK names a grade, HSS4241, and that listing has no review line, so the grade name is not evidence of edge life. Do not call the other sets M2. Oudtinz prints high-speed steel in the title and tungsten steel in a bullet.
Three typical situations, each with a recommendation from this comparison.
You mill aluminium and light steel on a mill or mill-drill, and you can inspect each cutter. AFUNTA is the top pick on review volume, at about £16.99 with 4.5 from 2,455 reviews. Centre cutting is not stated, so add a slot drill if you need to plunge. A 2–12 mm set does not fit a handheld router.
You cut MDF, ply, or acrylic and the collet is 3.175 mm. Hozly is five identical solid-carbide downcuts at about £16.99, with 4.4 from 251 reviews. Slow the feed so chips do not pack. It is not a mixed diameter set, and it does not fit a 6 mm or 1/4 inch collet.
You want a rail-and-stile pair for wooden door or window frames, and the router has a 1/2 inch collet. Socoje is two carbon-steel cutters at about £21.99. The listing has no review line. Ignore the end-mill star ratings. It will not fit a 1/4 inch-only router, and it is not a metal mill.
Eight listings do not share one spindle. AFUNTA, ten HSS mills from 2 mm to 12 mm at about £16.99, is the top pick: 4.5 from 2,455 amazon.co.uk reviews, the largest sample among listings with at least 100 reviews, tied on score with ASNOMY. You still have to check flute count, because the same sample includes 2-flute and 3-flute pieces, and centre cutting is not stated. ASNOMY, about £14.24, is the best value: centre cutting is stated, the score is the same 90, and 1,595 reviews mostly describe aluminium. QWORK is cheaper and names HSS4241, but it has no review line, so it is not the best value. The carbide packs and the rail-and-stile pair stay separate purchases.
ASNOMY 10-piece HSS end mill set, 2-12 mm
Same top score at about £14.24, with centre cutting stated and 4.5 from 1,595 reviews.
