The best stone drill bits, compared.
Top pick: Bosch Professional 7-piece CYL-3 concrete drill bit set, 4-10 mm Best value: toolant masonry set, 4–10 mm, 5 pieces – Five plug diameters at about £9.99. The 4.5-star line is a shared sample with the 6 mm ten-piece, and reviewers report flutes that clog in brick. Updated October 2026.
A stone drill bit is the consumable that cuts brick, block, concrete, natural stone, or a hard tile. Titles often put stone, masonry, and tile on one box, which is how a carbide tip ends up on porcelain and cracks the glaze. You choose by the chuck you own and by the surface you touch first. A carbide masonry bit suits a hammer or combi drill with a three-jaw chuck. A diamond bit suits porcelain, granite, and marble with the hammer switched off. Shank, diameter, and surface are set out in the [stone drill bit buying guide](/hub/drilling-and-accessories/stone-drill-bit/sub/stone-drill-bit-buying-guide). On amazon.co.uk the same search returns carbide masonry sets, diamond hole saws, an diamond core, one set, and a packet of 1–2.5 mm rotary points. Carbide with the hammer on is for common brick, block, and mortar in a three-jaw chuck.

Question 1 of 2
Which chuck are you using?
The Bosch Professional CYL-3 set, model 2 607 017 082, is seven carbide bits from 4 mm to 10 mm, including two 6 mm bits, with a cylindrical shank for a three-jaw chuck on an impact drill. The amazon.co.uk line is 4.7 stars from 19,730 reviews, and readers often say the bits cut brick and concrete faster than worn or cheap bits they already owned. The listing claims two carbide cutters, a 2-flute U-shape for dust, and hammer-proof performance according to ISO 5468, and it names the set as particularly suited to dowel holes. Lengths run from 4 × 40 × 75 mm up to 10 × 80 × 120 mm, and the set weighs 215 g. Reviewers who drill a lot of hard concrete still say they prefer SDS bits, so this is the top pick for a combi drill and ordinary brick or mortar, not for a day in structural concrete. One reviewer received a shank they did not want, and another reported a plastic case that arrived damaged or melted. The Number of Pieces field says 1, while the scope line lists seven bits; the contents to follow are those seven lengths, at £16.52, which some reviews call high.
Pros
Cons
Best for: Home fixings and pipe clips in brick or mortar, on an impact drill with a three-jaw chuck
Less suitable: A day of hard concrete where you already want SDS-Plus, or a chuck that only takes an SDS shank
Specifications
Common questions
Will the Bosch CYL-3 set fit a cordless combi drill?
The listing says it can be used in impact drills. The shank is cylindrical, so it needs a three-jaw chuck, not an SDS chuck.
How many bits are in the box?
The scope of delivery lists seven bits from 4 mm to 10 mm. A separate field says 1 piece. Use the scope line.
Does the listing mention ISO 5468?
Yes. A bullet says the bits are hammer-proof according to ISO 5468.
YESHLiky is a diamond set titled as 6, 8, 10 and 12 mm with a hex shank and six pieces, listed at £6.56. The bullets claim vacuum brazing, a wax core, a cross tip with four straight flutes, and a speed of 2,000–5,000 rpm with light pressure. The amazon.co.uk line is 4.7 stars from 8 reviews, and only four texts are in the file, so that star line is a thin sample. Those reviews mention drilling tiles to hang a shower mixer, and clean holes in granite, ceramic, marble, stone and glass with moderate pressure and water. One buyer expected a five-piece set and received six pieces. The included-components field names only a triangular drill bit, which does not match the six-piece title. There is not enough written criticism to name a repeating defect, and there is not enough evidence to say how many holes a bit will last.
Pros
Cons
Best for: A cheap trial of 6–12 mm diamond bits for a few tiles, if you can return a mismatch
Less suitable: Anyone who wants a large review sample before trusting the bit with a finished porcelain wall
Specifications
Common questions
Can it drill porcelain?
The bullets say porcelain, ceramic, granite, marble and stone. The surface field lists stone, ceramic and glass.
Does it need water?
The listing says a wax core cools dry drilling and that water extends bit life.
How many reviews are on the listing?
The listing line is 4.7 from 8 reviews. The saved listing contains 4 review texts.
WORKPRO lists eight SDS-Plus carbide bits at £16.99, in a storage case: 6 mm and 8 mm at 110 mm, plus 5, 6, 7, 8, 10 and 12 mm at 160 mm. The amazon.co.uk line is 4.6 stars from 1,361 reviews. The bullet describes four grooves on the SDS-Plus shank and names SDS-Plus rotary hammers from Bosch, DeWalt, Makita and Milwaukee. Reviewers say the set does the job in brick and concrete, and that the short 110 mm bits and the case help in a tight space. The same sample includes a carbide tip lost after seven holes on one bit and after four holes on the next, in 6 mm brick for rawl plugs, plus a 6 mm bit that wobbled and went blunt quickly. The seller states the bits are not for tile, glass or mirror. One captured review about a faulty plug on a reel does not describe this set and is not a fault in the bits. The shank will not lock in a three-jaw combi drill.
Pros
Cons
Best for: Brick and concrete holes on an SDS-Plus rotary hammer, including tight spots that need the 110 mm bits
Less suitable: A combi drill with a three-jaw chuck, or any hole in tile, glass or mirror
Specifications
Common questions
Will these WORKPRO bits fit a combi drill?
No. They are SDS-Plus bits. The listing says they fit SDS-Plus rotary hammers such as Bosch, DeWalt, Makita and Milwaukee.
Can they be used on stone?
The listing says concrete, brick, stone and masonry. It also says they are not for tile, glass or mirror.
What lengths are in the case?
6 mm and 8 mm at 110 mm, plus 5, 6, 7, 8, 10 and 12 mm at 160 mm, and one storage case.
The toolant five-piece set lists 4, 5, 6, 8 and 10 mm bits at £9.99, with a claimed YG8X carbide tip and a shockproof hammer-drill design. The listing line is 4.5 stars from 2,220 reviews, and those texts are the same sample as the ten-piece 6 mm listing, including the same reviewers, so the two counts must not be added together. The notes cover concrete paving, Hardie board, mortar and hard precast concrete, including work on a small DeWalt without an SDS drill. They also record flutes that clog in brick, one bit that arrived bent, and one bit that snapped under sideways pressure while stitch-drilling. The shank field says brace, the finish field says titanium, and the bullets do not confirm a storage case. This is the best value when you want several plug diameters for £9.99 and you accept that the review sample is shared. It is a weak buy if you need a confirmed case, or a flute that clears brick dust without you stopping to pull the bit out.
Pros
Cons
Best for: Occasional brick and concrete fixings when you want 4–10 mm bits and a low shelf price
Less suitable: Anyone who needs an independent review sample, a confirmed case, or flutes that clear brick dust on their own
Specifications
Common questions
Which diameters are in the 5-piece toolant set?
The bullets list 4 mm, 5 mm, 6 mm, 8 mm and 10 mm.
Is the 2,220 review count unique to this 5-piece set?
The listing shows 4.5 from 2,220 reviews. The review texts in the saved listing match the 10-piece 6 mm toolant file, so the samples are not independent.
What shank does the listing give?
The specification field says brace.
Ten 6 mm toolant bits, model TA01042004, are listed at £11.99 with a round shank that has flats and a claimed YG8X tungsten-carbide tip. The amazon.co.uk line is 4.5 stars from 2,220 reviews, and the 50 captured texts are the same sample as the five-piece set, so they are not a second opinion. Reviewers describe concrete paving after other bits had struggled, stitch-drilled heavy blocks that stayed sharp, and tough concrete on a small DeWalt drill without an SDS machine. The same notes say the flutes clog in brick, so the bit has to be worked out by hand, and that one bit in a pack arrived already bent. Another bit snapped after it was pulled sideways to break the web between stitch-drilled holes. A reviewer wanted a smaller diameter than this 6 mm-only box, and the bullets do not state water cooling or a storage case. The set suits a run of identical 6 mm holes in concrete or brick if you clear the dust often.
Pros
Cons
Best for: A job where every hole is 6 mm and you want spare carbide bits for a chuck drill
Less suitable: Mixed plug sizes, or brick work where you cannot stop to clear a packed flute
Specifications
Common questions
What size are the toolant bits in this box?
Every bit in this listing is 6 mm. The set contains 10 pieces.
Which shank does this toolant set use?
The listing says a round shank with flats, for a chuck that can grip those flats.
Does the listing include a storage case?
The captured bullets do not say a case is included.
MINLAYCUT packs four vacuum-brazed diamond hole saws at 6 mm, 6 mm, 8 mm and 10 mm, plus a 6 mm carbide triangle bit, on a 6.35 mm quick-fit hex shank, at £19.99. The listing is 4.5 stars from 342 reviews, and 43 texts were read. Reviewers drilled 10 mm porcelain, including outdoor slabs, when masonry bits did not, with reports of eight 10 mm holes kept cool with water and twelve 6 mm holes in 10 mm tile. The bullets claim cooling wax so the bit can run dry, yet several reviewers still dipped the bit in water, and high speed burned bits out. Some bits lasted only about two holes, and one broke in the first few seconds, so the life is uneven. Diamond height is listed as 8 mm and drilling depth as 35 mm, on a 65 mm overall length. The bullets do not confirm a case, and the set is not described as a hammer bit.
Pros
Cons
Best for: A few 6–10 mm holes in porcelain or ceramic when you can keep the speed down and add water
Less suitable: A long run of holes, a hammer-only job, or anyone treating the wax as a promise you never need water
Specifications
Common questions
Can this MINLAYCUT set be used on marble?
The listing names marble, granite, porcelain and ceramic tile.
Does it need water?
The bullets say the wax core allows dry drilling and that the set can be used dry or wet.
What is the extra carbide bit for?
The listing says the 6 mm carbide bit is there to stop the diamond bit wandering while you start the hole.
The BULLITT set is six tungsten-carbide bits at 4, 5, 6, 8, 10 and 12 mm, with a tri-flat shank and a claimed storage box, listed at £14.49. The amazon.co.uk line is 4.5 stars from 152 reviews. The title and a bullet say the set has passed PGM certification, and that mark was not checked on a physical bit. Reviewers report a concrete driveway for fence posts, sound work in brick, and hex flats that allowed quick changes in an impact driver. One bit blunted the first time it was used, one reviewer called the bits totally useless on porcelain even though the bullet names ceramic and tile, and another struggled with concrete on three of four holes while brick was fine. Model BTT1701.6S and part number BTT1701.7S both appear on the listing, and the country of origin is given as Hong Kong. The range suits a three-jaw chuck when you want a 12 mm bit in the same box, with the PGM line left as a claim.
Pros
Cons
Best for: A three-jaw chuck when you want 4–12 mm masonry bits and a box, for brick and light concrete
Less suitable: Porcelain tile, or a specified anchor that needs a PGM mark you can verify on the bit
Specifications
Common questions
Does the Bullitt listing include a case?
Yes. The bullets describe a storage box with an EVA lining.
Is the PGM mark confirmed on the bits?
The title and a bullet claim PGM certification. The saved listing does not include a photo of the mark.
Can it be used on stone?
The listing is a masonry set and the bullets name concrete, brick, ceramic, tile and cement.
LEKOMESH is ten 6 mm vacuum-brazed diamond core bits with an M14 thread, each 60 mm long with a 10 mm diamond height, listed at £43.99. The amazon.co.uk line is 4.4 stars from 299 reviews, and 23 texts were read. Some reviewers cut hard porcelain that had burned other brands, and one said 18 mm porcelain floor tiles felt easy, while another described 1 inch holes in sandstone tiles. Other bits were blunt after about four holes, or after about six holes in 10 mm porcelain. The seller states a speed of 6,000–11,000 rpm and a cooling wax core for wet or dry drilling, with diamond grit claimed as #35/40. The thread fits an angle grinder, and a drill needs an SDS or hex adapter, because this is not an SDS bit by itself. You are paying £43.99 for one diameter, and the written hole counts do not show a long life on every bit.
Pros
Cons
Best for: Repeated 6 mm holes in porcelain or stone tile on an M14 angle grinder, inside the stated speed band
Less suitable: A combi drill with no adapter, mixed diameters, or a buyer expecting each bit to last a whole bathroom
Specifications
Common questions
Will this LEKOMESH set fit a combi drill?
Not directly. The listing says the M14 thread fits an angle grinder, and that a drill needs an SDS or hex adapter.
Are the ten bits different sizes?
No. The set is ten pieces of 6 mm.
Does it need water?
The bullets claim wet or dry use, with a cooling wax core.
Camdios lists ten bits at £11.98 with a 3-flat shank, and the bullet gives 3, 4, 5, four 6 mm, 8, 10 and 12 mm, while the title also says 1/8 inch to 1/2 inch and seven sizes. The listing is 4.3 stars from 6,225 reviews. The brand field is Camdios, and the bullets plus at least one review also say TITGGI. Some reviewers drilled shower tiles, brick, concrete and hard Cornish stone, including brick without hammer action on a 12 V drill with water every 15 seconds. Small diameters are a repeated failure: one bit broke on first use, the smallest bent, and the next size snapped its tip. One porcelain job lasted about three holes, and dust packed the flute so the hole stopped clearing. The bullet says to cool the bit with water and control the speed, which matches the ceramic jobs that worked, and it does not make the small bits a long-life set.
Pros
Cons
Best for: A small mixed job in brick or ceramic tile when you will use the larger sizes and keep water on the bit
Less suitable: Porcelain that needs more than a couple of holes, or anyone relying on the 3 mm and 4 mm bits
Specifications
Common questions
Does this set say to use water?
Yes. A bullet says to cool with water and to control the speed.
What shank does it use?
The listing says a 3-flat shank for a standard drill.
Why do some texts say TITGGI?
The brand field is Camdios. The bullets, and at least one review title, also use the name TITGGI.
BRSCHNITT sells four 6 mm vacuum-brazed diamond hole saws and one carbide positioning bit, with a hex shank, a 65 mm length and an 8 mm diamond height, at £18.99. The listing is 4.3 stars from 1,012 reviews. Readers report porcelain after a new masonry bit had failed, a hole in a granite slab, and smooth holes in 9 mm ceramic bathroom tiles. One bit did 15 holes in 16 mm porcelain for a pergola when it was kept cool, while another reviewer was struggling by hole six, and one said the bit was not up to 20 mm patio porcelain. The bullet says water could prolong life, and wax inside the saw stopped the drilled core coming out for one reviewer. An angle grinder is suitable only if a drill chuck is fitted, and the set is not described as an SDS hammer bit. Grit is claimed as #50/60, and the bullet states a quick-fit of 6.5 mm.
Pros
Cons
Best for: A batch of 6 mm holes in porcelain, ceramic or a granite slab, if you cool the bit and clear the wax
Less suitable: Thick patio porcelain, mixed diameters, or an SDS hammer with no drill chuck fitted
Specifications
Common questions
Will these BRSCHNITT bits drill porcelain?
The title and bullets name porcelain, ceramic, stone, granite and marble. The surface field also lists concrete, glass, plastic, rock and tile.
Do they need water?
The listing says using water could prolong the lifetime. It does not say water is mandatory.
Can they go on an angle grinder?
The bullet says yes only if you fit an angle-grinder drill chuck.
XLLGYL1 lists ten carbide bits from 3 mm to 12 mm at £6.69, with a hex shank and a claimed heat-treated carbon-steel body. The amazon.co.uk line is 4.2 stars from 62 reviews, and 18 texts were read. One reviewer stepped up from a small bit for picture hooks in a 100-year-old house, and a 10 mm bit cut brick more easily than that reviewer expected. A 5 mm bit melted and snapped after about 1 cm in ordinary brick, and other bits needed sharpening after a minute or less on hard brick or stone. One pack arrived with a broken bit and at least two bits that looked already used. The highlight lists 3, 4, 5, four 6 mm, 8, 10 and 12 mm, while a later bullet also names a 7 mm bit, so the size mix is not settled. The bullets also name glass, porcelain, metal and wood, which the hard-brick reviews do not support.
Pros
Cons
Best for: One low-stakes hole in soft brick if you can return a pack that arrives damaged
Less suitable: Hard brick, a 5 mm plug hole you cannot afford to lose, or a title that promises porcelain and metal as well
Specifications
Common questions
Which sizes are in the box?
The item highlight lists 3, 4, 5, four 6 mm, 8, 10 and 12 mm. A later bullet also says a 7 mm bit is included. Both lines are on the listing.
Does the listing say it drills metal?
Yes. A bullet names metal as well as masonry, tile and glass. That is a listing claim, not a separate test.
Is a storage case specified?
The captured listing does not describe a case. Reviewers mention storage and say the sizes are hard to tell apart.
GZCYMY is a 30-piece diamond-coated set listed at £4.99, with bullets naming 1 mm, 2 mm and 2.5 mm, and an item weight of 10 g. The amazon.co.uk capture has no rating line and no review text, so there is no owner account of a hole in stone or glass. The shank field is empty, and the bullets say the bits fit most rotary tools and hanging grinders, which is a collet rather than an SDS chuck or a masonry shank for a combi drill. The surface field says glass, while the item highlight also names ceramic, stone and jewellery crafting. Included components are recorded as no. Stone is named in the highlight, which is why the set remains in this category, but the diameters and the rotary shank mean it is not a wall masonry set. Leave it if the job is brick, concrete or a wall plug.
Pros
Cons
Best for: Fine rotary-tool work in glass or jewellery if you accept a listing with no reviews
Less suitable: Any wall plug, brick, concrete, or a drill that needs a masonry shank
Specifications
Common questions
Will this set fit a hammer drill?
The bullets say the shank fits rotary tools and hanging grinders. They do not describe an SDS or three-jaw masonry shank.
What diameters are included?
The specification field says 1 mm. The bullets say 1 mm, 2 mm and 2.5 mm.
Is there an Amazon rating?
The listing has no customer-review line, so the rating is not available.
We compared twelve amazon.co.uk stone drill bit listings against public UK sources on shanks, masonry dust, and anchor-bit marks. Scores use the listing price, the star line, the review count, and the limits the seller states. This is not a lab test, and we did not check a PGM mark on a physical bit.
Surface and bit family
30%Carbide for brick and block with the hammer on, diamond for porcelain and glazed stone with the hammer off, and SDS-Plus only where the listing allows masonry rather than tile.
Shank and chuck fit
25%A three-jaw chuck, a hex holder, an SDS-Plus hammer, an M14 grinder, and a rotary collet are different tools. A bit that cannot lock in the chuck you own scores down.
Diameter range
15%Plug holes need the stated millimetre, not the widest bit in the box. A single 6 mm size is useful for a repeat hole and weak when the plug changes.
Amazon review evidence
20%A stated limit plus a large amazon.co.uk review count outweighs an industrial title. A shared review sample is counted once. A missing rating stays missing.
Price and stated limits
10%Shelf price in GBP is weighed against what the listing excludes, including tile on an SDS set, a single diameter at a high price, and wear reported after a few holes.
Choose the family before the brand. Brick and block want carbide in the chuck you own. Porcelain wants diamond with the hammer off. An SDS-Plus bit is a different shank, and a 1 mm rotary point is not a wall bit. The twelve listings below are the sets on this page.
A stone drill bit is the consumable that makes the hole. The drill only turns it. On amazon.co.uk the same search returns carbide masonry sets, diamond hole saws, an M14 diamond core, one SDS-Plus set, and a packet of 1–2.5 mm rotary points. Those are different tools. Carbide with the hammer on is for common brick, block, and mortar in a three-jaw chuck. Diamond with the hammer off is for porcelain, glazed stone, granite, and marble.
An SDS-Plus shank locks in an SDS rotary hammer. It will not grip in a combi drill. WORKPRO is the SDS-Plus set on this page. Bosch CYL-3 and the toolant sets are the chuck bits.
A title that also says tile does not make a tungsten tip safe for porcelain. Homebuilding treats that tip as the wrong tool. Use diamond, hammer off, then a masonry bit for the wall behind the tile.
Packed flutes stop the hole clearing. Withdraw a masonry bit and clear the dust. On a diamond bit, high speed and hard pressure burn the tip even when the listing mentions wax. Water is what several reviewers used to keep going.
The first cut is the surface, not the brand on the box. Common brick and block take a carbide masonry bit with the hammer on. Porcelain, glazed stone, glass, and mirror take a diamond bit with the hammer off. Homebuilding says a tungsten tip is the wrong tool for porcelain, and the WORKPRO listing excludes tile, glass, and mirror. After the glaze, the wall behind still needs a masonry bit sized for the plug.
The shank decides whether the bit fits the chuck you already own. A cylindrical shank, a round shank with flats, or a three-flat shank fits a three-jaw chuck. Bosch CYL-3 is cylindrical. The toolant ten-piece is round with flats. Bullitt and Camdios are three-flat. The toolant five-piece lists the shank as brace, so check the grip before you rely on it. A hex shank often sits in a quick-change holder. MINLAYCUT, BRSCHNITT, YESHLiky, and XLLGYL1 are hex.
Three typical situations, each with a recommendation from this comparison.
You are fitting shelves in common brick with a combi drill, so you need a carbide set around 4–8 mm and the right plug. Bosch CYL-3 gives 4–10 mm on a cylindrical shank, with the largest amazon.co.uk review count in this comparison.
You are fixing into porcelain, so you need a diamond bit, hammer off, then a second bit for the wall behind. MINLAYCUT is a hex set from 6 mm to 10 mm with a carbide guide. Keep the speed down and expect uneven life if the bit runs hot.
You own an SDS rotary hammer and you are drilling concrete, so you need SDS-Plus. WORKPRO is eight carbide bits from 5 mm to 12 mm with a case, including short 110 mm bits. The listing says they are not for tile, glass, or mirror.
For a combi or impact drill in brick and mortar, Bosch CYL-3 is the top pick: 4–10 mm, a cylindrical shank, and 4.7 stars from 19,730 amazon.co.uk reviews at about £16.52. If you want several plug sizes for about £9.99, the toolant five-piece is the best value, with the limit that its 2,220 reviews are the same sample as the ten-piece 6 mm set and the flutes clog in brick. Use WORKPRO only in an SDS-Plus hammer, and use a diamond set, hammer off, when the first surface is porcelain.
toolant masonry set, 4–10 mm, 5 pieces
Five plug diameters at about £9.99. The 4.5-star line is a shared sample with the 6 mm ten-piece, and reviewers report flutes that clog in brick.
