The best SDS max chisels, compared.
Top pick: Nucraft angled tile chisel – Highest shelf score in the set: a stated 15 degree angle and 300 × 80 mm at about £11.04, 4.6 from 105 ratings, with no shank contradiction on the listing. Best value: Bosch PRO SDS max-4C flat – Lowest price in the set for a single flat, about £9.95, with 4.5 from 1,447 ratings. The 280 mm scope line and the 37 cm dimensions still disagree. Updated October 2026.
An SDS max chisel is a steel demolition accessory with a slotted shank of about 18 mm. It locks into an SDS max rotary hammer or breaker. It does not fit a 10 mm SDS Plus chuck. In the UK you buy one when you already own or hire a heavy hammer for concrete, masonry, render, or a large tile bed. You match the shank printed on the chuck before you match the tip. A point starts a break. A flat, often about 25 mm, dresses and splits. A wide or spade blade, about 40–80 mm, clears mortar and render. An angled wide blade lifts tiles. A gouge or U-groove cuts a slot. About 280–300 mm suits walls. About 400–450 mm adds reach on floors. Alloy, 40Cr or carbon-steel wording is a listing claim, not a life test. The hammer, not the chisel, sets vibration and dust. You need hammer-only mode, a side handle and the tool manual. Shank, tip and length are set out in the [SDS max chisel buying guide](/hub/drilling-and-accessories/sds-max-chisel/sub/sds-max-chisel-buying-guide).

Question 1 of 2
What are you breaking?
Nucraft’s NU-M06 is one SDS max tile chisel at £11.04, titled 300 × 80 mm with a 15 degree working angle, and listed at 322 g. Across 105 amazon.co.uk ratings the line is 4.6, the joint highest star figure in this set, from a sample large enough to keep. UK reviews in the file are short and positive about tiles and render. Across the first 50 reviews, which are mostly not from the UK, buyers report floor tiles coming up, and they dispute edge life: one failure after about 6 m² of mosaic, another of about 80 m² of tiles and screed. Several texts say it does not fit SDS Plus. The 300 mm length is called hard on the back for floor work. It is the top pick here because the angle and size are printed, the star line is high, and the listing does not contradict its own shank. That is a shelf comparison on the October 2026 capture, not a timed tile lift.
Pros
Cons
Best for: You have an SDS max hammer and a tile bed, and you want the angled wide blade at this price.
Less suitable: An SDS Plus chuck, a concrete pad that needs a point, or a long floor session where 400 mm reach matters more than the angle.
Specifications
Common questions
Is this Nucraft chisel angled?
Yes. The title states a 15 degree working angle, and the size in the title is 300 x 80 mm.
Will it fit SDS Plus?
The listing specifies an SDS max shank. Review text says it does not work with SDS Plus.
What is in the box?
Included components lists one chisel. A case is not stated.
The GEINXURN set is £22.99, and the title lists a point, a flat, a wide blade and a bent chisel in 40Cr, with a size line of four pieces at 18 × 300 mm and a stated weight of 2.27 kg. The star line is 4.6 from only eight ratings. The included-components line says an SDS-Plus shank floor scraper, which contradicts the title, the 18 mm size line, and UK reviews that discuss an 18 mm shank. A UK comment says it held up for an afternoon on a shed base. Another UK buyer ordered 18 mm by mistake for a 10 mm drill. Some reviews say three pieces arrived rather than four. German comments in the file are first impressions, not a life test, and the bent piece has no angle in degrees. Keep it only if you open the carton against the SDS max title rather than against the Plus components line.
Pros
Cons
Best for: You have checked the chuck is SDS max and you will confirm four 18 mm shanks in the carton.
Less suitable: Anyone who needs a settled shank line, a large review sample, or a stated angle.
Specifications
Common questions
Is this set SDS max or SDS Plus?
The title, bullets, and size line say SDS max and 18 mm. The included-components line says an SDS-Plus shank floor scraper. Both lines are on the listing.
Which profiles does the title list?
Point, flat, wide, and bent chisels, in 40Cr steel, for concrete, stone, and tile.
How many reviews are on the listing?
The amazon.co.uk line says 4.6 out of 5 from 8 ratings. Eight review texts are stored with that listing.
The Bosch PRO SDS max-4C flat, part 1 618 600 210, is listed at £9.95, with a scope line of 25 × 280 mm, a stated weight of 500 g, and Italy as the origin. Item dimensions on the same page say 37 × 2.5 cm, and reviews also mention other lengths, including a UK comment of 600 mm, so the length is not one verified figure. The star line is 4.5 from 1,447 ratings, the largest count in this set. UK comments call it a quality flat for brick and concrete. One UK buyer returned it because it did not fit an SDS drill, which is the Plus-versus-max mistake rather than a fault in the flat itself. A minority of texts report fast blunting. It is the best value here on shelf price and review count for a single flat, with the length clash left visible. The scope of delivery is the chisel, not a case, and it is not a tile blade.
Pros
Cons
Best for: You need one SDS max flat for brick or concrete and you will measure the steel when it arrives.
Less suitable: A tile lift, a cable chase, or an order that needs one agreed length before you pay.
Specifications
Common questions
How long is this Bosch flat chisel?
The scope line, item type, and warranty line say 25 x 280 mm. Item dimensions say 37 cm long. Those figures are both on the listing and are not resolved here.
Does it include a case?
The scope of delivery is the chisel. A UK review says it arrived as a single item, not a case.
Will it fit every SDS drill?
The listing says all SDS max rotary hammers. It does not say SDS Plus. One UK review says it was returned because it did not fit an SDS drill.
Firecore’s FS18312 is one straight SDS max wide chisel at £17.09, with the bullets at 30.5 cm long and a 7.6 cm blade, and a stated weight of 700 g. The size field says straight chisel, so no working angle is claimed. The star line is 4.4 from 599 ratings, the second-largest sample here. A UK review describes lifting about 50 m² of kitchen tiles. Other UK texts report the chisel breaking in light or tile use, and the wider review slice includes both large areas with little wear and a shank that broke in the chuck. The bullets say heat treatment to increase impact resistance and to reduce breaking strength, which is the listing’s wording rather than a measured life. It is the straight wide option when you want hundreds of ratings rather than a stated 15 degree bend, and the edge can still fail on the same kind of job the 50 m² review finished.
Pros
Cons
Best for: You want a straight wide blade for tiles or mortar and a review count in the hundreds.
Less suitable: A floor where you want the hammer held off the surface by a cranked blade, or a chase that needs a gouge.
Specifications
Common questions
Is the Firecore chisel cranked?
The listing does not state an angle. The size field says straight chisel, and the blade edge is flat.
Which hammers does the listing name?
SDS max demolition hammers and rotary hammers with a splitter function.
How wide is the blade?
The bullets say 7.6 cm. The title says 300 x 75 mm.
Einhell part 49190103 is a three-piece SDS max set at £29.99: a point, a 25 mm flat and a 40 mm flat, each described as 400 mm. The star line is 4.4 from 272 ratings, and the listing says it fits Einhell hammers and other manufacturers’ SDS max shanks. Review texts in UK English are thin. Themes elsewhere include block and light concrete, a piece that broke quickly for some users, and one comment that a set did not fit an Einhell hammer. The item weight is printed as 1 g, which is not a credible mass, and the handle-material line says wood, plastic and rubber. This part is not Einhell UK’s 49190110 at £30.95, which names 40Cr, so that steel line does not belong on this listing. The 400 mm length is the reason to consider it when a 280–300 mm single is too short, once you have checked the carton against 49190103.
Pros
Cons
Best for: You want 400 mm reach with a point and two flats, and the chuck is already SDS max.
Less suitable: A wide or angled tile blade, or anyone treating Einhell part 49190110’s steel line as this listing.
Specifications
Common questions
What is in the Einhell set?
The listing includes one pointed chisel and two flat chisels, a 25 mm and a 40 mm, each described as 400 mm long, with an SDS max shank.
Does the listing say it fits only Einhell hammers?
No. It says Einhell drill and demolition hammers, or other manufacturers with an SDS max shank. One review says a set did not fit an Einhell hammer.
Is the weight 1 g?
That is the figure printed on the listing. No other weight is given.
The Keewaki tube is four 450 mm SDS max chisels at £36.99: a point, a 25 mm flat, an 80 mm wide blade and a 25 mm U-groove, with a stated weight of 1 kg. The amazon.co.uk line is 4.2 from 32 ratings. The first 25 review texts in the file are marked United States, so they are not a UK-only sample. Those texts describe a long, heavy set used on concrete and block, and several returns from people who needed SDS Plus. One comment says the heads look cast rather than forged, and another says a wide edge lost sharpness after a few hours on fence-post concrete. A specification field says carbide tipped, while the bullets describe heat-treated alloy steel and do not mention carbide, so that field stays unverified. At £36.99 it is the dearest listing here, and the extra length helps on a floor only if the chuck is already 18 mm SDS max.
Pros
Cons
Best for: You already run an SDS max hammer and want floor reach plus a U-groove in one tube.
Less suitable: An SDS Plus drill, or a single tile job where one wide blade is enough.
Specifications
Common questions
Will this Keewaki set fit an SDS Plus drill?
The listing says no. It states an 18 mm SDS max 5-slot shank only, and says it is not compatible with 10 mm SDS Plus or hex tools.
Which tips are in the set?
The bullets list one point, one 25 mm flat, one 80 mm wide chisel, and one 25 mm U-groove, all at 450 mm, plus a storage tube.
Does the listing prove a carbide tip?
A specification field says carbide tipped. The feature bullets describe heat-treated alloy steel and do not mention carbide. Treat that field as unverified.
The Shanrya set is three carbon-steel chisels at £24.98, marked SDS max with five pits, for scaling, flat and point work, with Hilti named in the bullets and a stated weight of 1.47 kg. The amazon.co.uk line is 4.1 from three ratings, and no review text is available, so there is no praise or complaint to quote. Length is not given in millimetres; the size field says Extended. Five pits on this title means the SDS max groove pattern, not proof that only a Hilti chuck will lock it, and other brands are not named. At £24.98 it sits between a four-piece set at £22.99 and a 400 mm three-piece at £29.99 without adding a stated width or angle. Skip it for a first purchase until you can confirm the length, because three ratings and no written reviews are not a reason to prefer it.
Pros
Cons
Best for: You already use Hilti SDS max tools and can confirm the length before you rely on Extended.
Less suitable: A first chisel purchase, a stated tile width, or any choice that needs buyer comments.
Specifications
Common questions
Which shank does the Shanrya set state?
The title says SDS max (five pits). The bullets say it is compatible with SDS max five-pit systems and name Hilti electric tools.
How long are the chisels?
The listing does not give a length in millimetres. The size field says Extended.
What do buyers say?
The listing shows 4.1 out of 5 from 3 ratings. No review text is available, so praised and criticised points are not known.
Seven amazon.co.uk listings were scored from the stored star line, stars times 20, with deductions where the review count is thin or the listing contradicts itself. The top pick is the highest of those scores with a printed angle, a shank the listing does not contradict, and a review count large enough to keep. The best value is the lowest shelf price in the set among single flats with the largest review count. No laboratory life test was done, and a steel name is not treated as one.
Shank match
25%SDS max is about 18 mm and SDS Plus is about 10 mm. A title that says max and an included-components line that says Plus is scored down. An adaptor is not counted as a fit.
Tip for the job
25%Point, flat, wide, angled tile and gouge are scored as different tools. A set scores only when the listing names the tip you would actually use, and a stated angle counts only when degrees are printed.
Review evidence
20%The shelf score starts from the amazon.co.uk star rating times 20. A count of three or eight ratings is deducted. Review text marked outside the UK is not treated as a UK-only sample.
Length as printed
15%About 280–300 mm and about 400–450 mm are both valid, for walls and floors. Two lengths on one listing stay unresolved. A missing length in millimetres is a gap, not a long chisel.
Shelf price
15%Best value is the lowest amazon.co.uk price in this set for a single flat with a large review count. A dearer set does not take that slot because it contains more pieces.
Choose the shank before the tip. SDS max is about 18 mm and SDS Plus is about 10 mm, and they do not interchange. Then pick the profile for the surface in front of you, and a length you can hold without levering the steel. A set is only a saving when every piece is SDS max and one of those pieces is the tip you will actually use. Listing words such as heat-treated or 40Cr are not a measured life.
An SDS max chisel is a steel demolition accessory. The shank is the slotted end, about 18 mm, that locks into an SDS max rotary hammer or breaker. An SDS Plus chisel is about 10 mm. The two do not interchange, and an adaptor does not make an SDS max chisel fit an SDS Plus chuck. In the UK you usually already own or hire the heavy hammer. The chisel is the part you change for the job in front of you: concrete, masonry, render, or a large tile bed. Shank comes first.
SDS max and SDS Plus do not interchange. Ordering an 18 mm chisel for a 10 mm chuck is a return, not a fault in the steel. An adaptor does not close that gap.
A point is a poor tile lifter, and a flat is a poor chase. Levering a long chisel until the shank snaps is a handling mistake. Longer steel reaches further and breaks more readily if you pry with it.
Use hammer-only mode. Dry chasing with no extraction and no FFP3 is high-dust work where concrete dust can contain respirable crystalline silica. HSE’s control for that work is H or M class extraction plus respiratory protection at assigned protection factor 20.
The shank is the fit that matters before price or tip. SDS max is about 18 mm with the wide slotted pattern. SDS Plus is about 10 mm. They do not lock into each other’s chucks, and an adaptor is not a workaround. Read the chuck, then read every piece in the set. A title that says SDS max can still carry an included-components line that says SDS Plus. That is a contradiction to resolve in the carton, not a dual-size shank. Five pits on an SDS max title means the groove pattern.
After the shank, choose the tip for the surface, not a tube of four by default. A point starts a break in concrete or masonry. A flat, often about 25 mm, dresses and splits floors, stairs and frames. A wide or spade, about 40–80 mm, clears mortar and render. An angled wide blade is the tile tool. A straight wide blade is a different shape, even at a similar width, because it does not hold the hammer off the floor. A gouge or U-groove is for a slot, not for lifting tiles.
Three typical situations, each with a recommendation from this comparison.
You already have an SDS max breaker or a hire tool and a tile bed to lift. The Nucraft chisel is one 300 × 80 mm blade with a stated 15 degree angle, at about £11.04, with 4.6 from 105 ratings. Most of the first 50 reviews are not from the UK, and edge life in those texts is disputed.
You want one SDS max flat for brick or concrete and you will measure the steel when it arrives. The Bosch PRO SDS max-4C flat is about £9.95, with 4.5 from 1,447 ratings. The scope line says 25 × 280 mm and the dimensions say 37 cm.
You already run an SDS max hammer and want floor reach plus a U-groove. The Keewaki tube is four 450 mm pieces, including a 25 mm U-groove, at about £36.99, with 4.2 from 32 ratings. The first 25 review texts are marked United States, and a carbide field is not backed by the bullets.
In this set of seven amazon.co.uk listings, the top pick is the Nucraft angled tile chisel at about £11.04. The title states a 15 degree angle and 300 × 80 mm, the star line is 4.6 from 105 ratings, and the listing does not contradict its own shank. Most of the first 50 reviews are not from the UK, and edge life in those texts runs from about 6 m² to about 80 m². The best value is the Bosch PRO SDS max-4C flat at about £9.95, with 4.5 from 1,447 ratings. The scope line says 25 × 280 mm and the dimensions say 37 cm, so measure the steel when it arrives. None of these scores is a lab test.
Nucraft angled tile chisel
Highest shelf score in the set: a stated 15 degree angle and 300 × 80 mm at about £11.04, 4.6 from 105 ratings, with no shank contradiction on the listing.
Bosch PRO SDS max-4C flat
Lowest price in the set for a single flat, about £9.95, with 4.5 from 1,447 ratings. The 280 mm scope line and the 37 cm dimensions still disagree.
