Charlie White (Charlie DIYte)Expert source
A cordless rotary hammer is a battery SDS drill with a pneumatic hammer, for brick, block and concrete when a combi drill's hammer setting stalls. Most household and light-trade tools are SDS plus. You buy one in the UK for wall plugs in brick, a hole in block or concrete, or light chiselling away from a mains socket. Look for an SDS plus shank, a side handle, and a joule figure you can trace to the maker or the listing. Rotary only is the mode for wood and metal. Hammer-only is the mode for light chiselling. The box either includes the battery and charger or it says that it does not. Packs from different battery families do not interchange. Watts and torque cells on a listing can contradict the maker, so leave those cells out of the sort. Percussive tools around 15 m/s² can reach a worker's hand-arm action value in about 15 minutes. Concrete dust can contain respirable crystalline silica. Joules, shank and platform are set out in the [cordless rotary hammer buying guide](/hub/drilling-and-accessories/cordless-rotary-hammer/sub/cordless-rotary-hammer-buying-guide).

Which cordless rotary hammer fits this job?
Question 1 of 2
Do you already own Ryobi ONE+ 18 V packs?
The best cordless rotary hammers in detail
Our view
The Ryobi R18SDS-0 is the ONE+ body reviewers use on concrete, brick, and slate after a combi or hammer drill has stalled, including gate posts in an existing path and lifting floor tiles. amazon.co.uk shows 4.7 from 2,755 reviews at £90.29, and the title excludes the battery and charger. The listing states four modes without naming each one, plus an LED, an impact-stop function, 1,300 rpm, and 1.7 kg, and it does not print impact energy in joules. Owners call it light up a ladder with no lead, and they also say it runs hot on a long job and has less power than a mains SDS. A wonky chuck comes up as a known weakness, and one first unit had no hammer action until it was replaced. The same page prints 1,765 Nm beside 15 Nm, 2,500 W, and dimensions of 4.95 x 0.76 x 2.18 m, so those cells are not hole sizes you can trust. It is the top pick in this set when you already own ONE+ packs and you want the largest review file, with the battery still a separate purchase.
Pros
- Concrete, brick, and slate where a ONE+ combi stalled
- 4.7 from 2,755 reviews at £90.29
- Light enough for ladder work with no lead
- LED and an impact-stop function are listed
Cons
- Battery and charger are not in the box
- Runs hot on long jobs and has less power than a mains SDS
- Chuck alignment complaints, including one unit with no hammer action
- Amazon prints 1,765 Nm and metre-scale dimensions on the same page
Best for: You already own Ryobi ONE+ 18 V packs and you want an SDS plus body for brick, concrete plugs, and light tile lifting.
Less suitable: You have no ONE+ battery yet, or the job is a long run that a mains SDS would take.

Common questions
Does the R18SDS-0 include a battery?
No. The title says battery and charger excluded, and the included-components line is one SDS plus drill.
Which bits does the listing allow?
The bullet says to use SDS plus drill bits only. It also says four modes, with variable speed on the trigger and an LED.
What went wrong in reviews?
Buyers report a first unit with no hammer action that was replaced, chucks that were not true, and heat on long jobs. The listing average is 4.7 from 2,755 reviews.
Our view
The green UniversalHammer 18V is the body reviewers step up to from a combi in brick and block, for concrete lintels, fence posts, and lifting old plaster and tiles. amazon.co.uk shows 4.7 from 332 reviews at £97.92. The title states 2.0 J, and a bullet says a pneumatic hammer up to 16 mm in concrete. You get a depth stop and an auxiliary handle in a carton, with no battery and no charger, while the technical table still prints 2.5 Ah. One owner on a 2.5 Ah pack reports about 14-15 holes of 8 mm by 100 mm in concrete block, then a thermal cut-out after about 10 continuous holes. It mixes mud poorly on a small pack, and one motor smoked and failed while removing lime plaster. The listing gives 2 kg and a 2-year manufacturer warranty.
Pros
- 2.0 J and chiselling are in the title
- Bullet says up to 16 mm in concrete
- 4.7 from 332 reviews at £97.92
- Plaster, tiles, lintels, and fence posts in the review notes
- 2-year manufacturer warranty on the listing
Cons
- No battery, charger, or carrying case
- About 14-15 holes of 8 x 100 mm on a 2.5 Ah pack in one review
- Thermal cut-out on continuous drilling
- One motor smoked while removing lime plaster
Best for: You already own Bosch green 18 V packs and you want an SDS plus body for brick plugs and light chiselling.
Less suitable: You have no green battery yet, you want a case, or the work is continuous deep holes on a 2.5 Ah pack.

Common questions
Does this UniversalHammer include a battery?
No. The title says without battery, and the scope is a depth stop, an auxiliary handle, and a carton.
Can it chisel?
The title and the bullets list drilling, hammer drilling, and chiselling, with 2.0 J impact energy and an SDS plus holder.
Is a case included?
No. The scope is a carton, not a carrying case.
Our view
The GBH 18V-22 X kit is the same ONECHUCK name as the body-only listing, sold with two GBA 18V 5.0 Ah packs, a GAL 18V-40 charger, and an L-BOXX 136. amazon.co.uk shows 4.7 from four reviews at £319.20, so each remark is one person. The readable notes praise the two packs and the case, and they say SDS bits worked, while one reviewer had not tried cylindrical or hex bits. It is described as a large two-handed tool, and one buyer says the price was £479.99 when they wrote. The item weight is 6.98 kg, wood capacity is printed as 1 inch, and impact energy is blank. No defect is written in the three readable reviews. The box makes sense when you own no Professional 18 V packs and you want two 5.0 Ah batteries together, which four reviews cannot prove on their own.
Pros
- Two GBA 18V 5.0 Ah packs and a GAL 18V-40 charger
- L-BOXX 136 in the scope
- ONECHUCK, brushless, and KickBack Control stated
- SDS bits used in the readable reviews
Cons
- £319.20 with only four reviews
- Described as a large two-handed tool
- One reviewer cites £479.99 at the time they wrote
- Wood capacity is printed as 1 inch, and joules are blank
Best for: You own no Professional 18 V packs and you want this ONECHUCK body with two 5.0 Ah batteries and a charger in one order.
Less suitable: You already own 5.0 Ah packs, or you want a review sample larger than four.

Common questions
What is included besides the tool?
Two GBA 18V 5.0 Ah batteries, a GAL 18V-40 charger, an L-BOXX 136, a depth gauge, and an auxiliary handle.
How many reviews are there?
The listing shows 4.7 out of 5 from 4 reviews. One of them says the price was £479.99 when they wrote, and calls it a large two-handed tool.
Does the listing state chisel mode or joules?
No. It states ONECHUCK, a brushless motor, vibration control, and KickBack Control. A dust extractor is named as an attachment and is not in the scope line.
Our view
The Bosch Professional body 0611927000 is the 1.59 kg SDS plus hammer reviewers describe in solid concrete, with brushless and KickBack Control stated on the listing. amazon.co.uk shows 4.6 from 141 reviews at £122.95. The scope is a cardboard box, a depth gauge, and an auxiliary handle, and the bullets claim full performance from an 18 V 2.0 Ah pack that is not included. Readable criticism is the missing carrying case, many later reviews have no text, and no repeated mechanical defect is written down. Amazon still prints a 50 mm chuck, 80 Nm, and wood and metal capacities in hundredths of an inch, which do not describe this SDS body. A scraped question asks about chiselling, and the bullets do not answer it. Use it for plug holes when you already own Professional 18 V packs and you can set those attribute cells aside.
Pros
- 1.59 kg with brushless and KickBack Control stated
- Solid concrete in the readable reviews
- 4.6 from 141 reviews at £122.95
- Depth gauge and auxiliary handle in the carton
Cons
- No battery, charger, or carrying case
- Amazon prints a 50 mm chuck and 80 Nm
- Chisel mode is not confirmed in the bullets
- Many later reviews have no readable text
Best for: You already own Bosch Professional 18 V packs and you want a light SDS plus body for concrete plug holes.
Less suitable: You need to chisel, you have no blue battery yet, or you want a case in the box.

Common questions
Does this include a battery or a case?
No. The scope is a cardboard box, a depth gauge, and an auxiliary handle. A bullet mentions an 18 V 2.0 Ah battery as the pack it is meant to run on.
Is chiselling listed?
No. A scraped question asks about chiselling, and the bullets do not answer it. They do state KickBack Control, vibration control, and a brushless motor.
What did buyers say about the case?
One UK reviewer wanted a carry case as standard and expected to buy one. Other readable comments say it drills solid concrete. The average is 4.6 from 141 reviews.
Our view
The GBH 18V-22 X body is the ONECHUCK hammer reviewers call powerful and compact, including tile chiselling, at 2.52 kg with brushless, KickBack Control, and Vibration Control on the listing. amazon.co.uk shows 4.6 from 73 reviews at £176.95. The scope is a carton, a depth gauge, and an auxiliary handle, with no battery. ONECHUCK is stated for SDS plus, cylindrical, and hex bits, and a dust attachment is named without being in the box. Readable UK reviews are few, several later reviews have no body text, and the file records no repeated defect. One reviewer says they will update the review if it fails inside a warranty they call three years, which the listing does not print. Impact energy is absent from the Amazon row, so the £176.95 buys the body and the holder, not a joule figure you can quote.
Pros
- ONECHUCK for SDS plus, cylindrical, and hex
- Brushless, KickBack Control, and Vibration Control stated
- Tile chiselling described as easy in a review
- 2.52 kg body at £176.95
Cons
- No battery or carrying case
- Readable UK reviews are few among 73 ratings
- Impact energy is not on the Amazon row
- The dust attachment is named and not included
Best for: You already own Bosch Professional 18 V packs and you want ONECHUCK on the 22 X body without buying two batteries.
Less suitable: You have no blue pack yet, or you want a larger set of readable UK reviews before you spend £176.95.

Common questions

No. The technical table says batteries included: no, batteries required: yes. The scope is a carton, a depth gauge, and an auxiliary handle.
Is the dust extractor in the box?
No. The bullet names a GDE 18V-12 or GDE 12 attachment. The scope of supply does not include it.
Does the Amazon listing state joules or a chisel mode?
No. It does state ONECHUCK for SDS plus, cylindrical, and hex bits, plus KickBack Control, vibration control, and a brushless motor.
Our view
The Dong Cheng DCZC04-24 is the 2.8 J kit owners use on concrete walls, a garage floor, and a brick fireplace, with a 4.0 Ah pack and a charger in the box. amazon.co.uk shows 4.6 from 64 reviews at £99.99. The bullet states a brushless motor, a hammer-only mode, a DSC mechanical clutch, concrete to 24 mm, and up to 48 holes of 8 x 80 mm on a full charge, which is the seller's figure rather than a counted test in these reviews. Bits of 6, 8, 10, and 12 mm are included. A case is named in an ergonomic bullet and missing from the included-components line. Battery life is praised, and several buyers still want a second pack because one battery means waiting on the charger. The item weight says 6.3 kg against a 3.2 kg bullet, the speed cell says 4,500 rpm, the LED can sit behind the front handle, and one buyer expected a Bosch.
Pros
- 2.8 J, brushless, and a stated DSC clutch
- 4.0 Ah battery and charger at £99.99
- Concrete, a garage floor, and a brick fireplace in the reviews
- 6 mm, 8 mm, 10 mm, and 12 mm bits included
- 4.6 from 64 reviews
Cons
- Case is in a bullet, not in the components line
- Item weight 6.3 kg clashes with a 3.2 kg bullet
- LED can sit behind the front handle
- One buyer thought the listing was a Bosch
Best for: You want a Dong Cheng 20 V kit with more stated impact than the 2.1 J model and a clutch named on the page.
Less suitable: You need the case confirmed in the components list, or you thought you were ordering a Bosch.

A bullet says a sturdy carrying case. The included-components line names the battery, charger, and four drills, and does not name the case.
What safety feature is named?
The bullet names a DSC mechanical clutch and electronic reverse protection that disengage the drive if the bit jams.
Our view
The Dong Cheng DCZC22 is the 20 V kit reviewers use once a combi or a Black and Decker has stalled in brick and external walls, including 8 mm holes in granite blocks. amazon.co.uk shows 4.5 from 100 reviews at £79.99, and the scope includes a 4.0 Ah pack, a charger, four SDS plus bits, and a heavy-duty case. The bullet states 2.1 J, 1,400 rpm, 4,500 blows, a brushless motor, and a hammer-only mode for light chiselling, while the fourth function is cut off mid-sentence. Several owners call the battery life decent for the price against bigger brands. One charge lasted under five minutes and that unit was returned, and another arrived looking used before a refund. The item-weight line is 5.14 kg, which sits with the comments that call it slightly bulky. It is the best value here if you want battery, charger, and case together under £80 and you are not already on a Ryobi or Bosch 18 V system.
Pros
- 4.0 Ah battery, charger, four SDS plus bits, and a case at £79.99
- 2.1 J and a hammer-only mode are in the bullet
- Brick, external walls, and 8 mm granite in the review notes
- 4.5 from 100 reviews
Cons
- One battery lasted under five minutes and was returned
- A used-looking unit was sent and refunded
- The brand name put some buyers off
- Item weight is listed at 5.14 kg
Best for: You want a first cordless SDS kit with a 4.0 Ah pack and a case for brick and light granite, without a Ryobi or Bosch battery already on the shelf.
Less suitable: You already own ONE+ or Bosch 18 V packs, or you need a named clutch and a larger review file than 100.

The listing says it is compatible with Dong Cheng 20 V Max tools. It does not say it takes Bosch, Ryobi, Makita, or DeWalt packs.
Can it chisel?
Yes in the listing. The mode bullet includes hammer-only for light chiselling, alongside drill-only and rotary hammer.
Our view
The UniversalHammer 18V kit is the green hammer with a PBA 18V 2.5 Ah pack, an AL 18V-20 charger, a depth stop, and a carrying case, so the first holes do not wait on a battery you still have to buy. amazon.co.uk shows 4.5 from 100 reviews at £132.60. The title states 2.0 J, and a bullet says up to 16 mm in concrete. Reviewers call SDS bits easy to swap and the depth gauge useful when the holes repeat. It is heavier than a small drill, it cuts out with large bits, and the recharge is described as slow. One buyer returned it for lack of power, and a warranty claim replaced the motor, the switch, and a battery that would not charge. The title says 2.5 Ah while the technical table says 3,000 mAh, and the listing weight is 2 kg with a 2-year manufacturer warranty.
Pros
- 2.5 Ah PBA pack, AL 18V-20 charger, and a carrying case
- 2.0 J and chiselling in the title
- Depth gauge praised for repeated holes
- 4.5 from 100 reviews
Cons
- Cuts out with large bits
- Recharge described as slow
- One warranty claim replaced the motor, the switch, and the battery
- Title says 2.5 Ah and the table says 3,000 mAh
Best for: You own no Bosch green pack yet and your first holes are solid brick with a depth stop.
Less suitable: You already keep a larger green pack, or a tool that cuts out on small holes is the failure you are trying to avoid.

Can it chisel?
The title lists drilling, hammer drilling, and chiselling, with 2.0 J impact energy and an SDS plus holder.
What faults show up in reviews?
One buyer claimed a new motor, switch, and battery under warranty after cut-outs. Others say it cuts out on large bits or returned it for lack of power. The average is 4.5 from 100 reviews.
Our view
The GBH 18V-18 X is the 1.8 kg ONECHUCK body at £116.95, and the praise in the file is about changing SDS and ordinary bits in seconds and about the compact size. amazon.co.uk shows 4.3 from 55 reviews. KickBack Control and Vibration Control are stated, while brushless, joules, and a chisel mode are not. The bullets claim full performance with an 18 V 2.0 Ah battery, and that battery is not in the included items. More than one UK reviewer calls it too weak for the money, one could not get a bit back out after a single use, and another took a refund. A Spanish-language review cites 6 mm and 8 mm bits, which is not a UK concrete log. The table prints both 35 Nm and 5 Nm, plus 10 mm in wood and 10 mm in metal.
Pros
- 1.8 kg ONECHUCK body for SDS plus, round, and hex
- KickBack Control stated
- Bit changes described as taking seconds
- £116.95 if you already own a blue pack
Cons
- 4.3 from 55 reviews, with weak-power complaints
- A bit stuck in the chuck after one use
- No battery, and brushless is not stated
- Chisel mode and impact energy are absent from the listing
Best for: You already own Professional 18 V packs and you want the lightest ONECHUCK body for small bits.
Less suitable: You need confidence in concrete, a chisel mode, or a cleaner review record than this 4.3 line.

What did UK reviewers complain about?
Readable complaints are weak power, a refund, and a bit that would not come out of the chuck. The listing average is 4.3 from 55 reviews.
Our view
The ConBlom JI10059 is a yellow bare body the seller says will take a DeWalt 18 V or 20 V MAX pack, with 2.6 J written in a bullet and no battery in the box. amazon.co.uk shows 4.2 from 14 reviews at £59.99, and the readable texts do not describe a finished hole. One reviewer, using an 18 V 5 Ah DeWalt pack and a 14 mm SDS plus bit, says it cut out after about five seconds. Another had wanted a Milwaukee tool and received this DeWalt-fit body. The torque cells say 0.01 Nm, a bullet says three modes while a highlight says four, and the included-components field says "Drill Attachment". Brushless is stated, a clutch is not, and the item weight is 3.53 kg. Treat the 2.6 J line as a seller figure sitting next to a cut-out report, not as a checked concrete capacity.
Pros
- Seller states DeWalt 18 V and 20 V MAX fit
- 2.6 J is written in a bullet
- SDS plus and a chisel mode are listed
- Bare tool at £59.99 if you already own a DeWalt pack
Cons
- Cut out after about five seconds on a 14 mm bit in one review
- Readable reviews do not describe a finished hole
- Torque cells say 0.01 Nm, and the mode count clashes
- Only 14 reviews, and the brand is ConBlom
Best for: You already own a DeWalt 18 V pack and you are comparing a cheap SDS body against that cut-out report before you buy.
Less suitable: You need a finished-hole record, a named clutch, or a tool sold by DeWalt rather than described as compatible.

Yes. A bullet says 2.6 joules. The same listing’s torque field says 0.01 Nm, which is copied as listed and not treated as a checked figure.
What did reviewers say about power?
One reviewer, using an 18 V 5 Ah DeWalt pack and a 14 mm SDS plus bit, said it cut out after about five seconds. The listing shows 4.2 from 14 reviews.

The NailHsing Nh-rh18v-4m is a tool-only body the seller says runs on a Makita 18 V pack you already own, with SDS plus, three modes including chiselling, and five bits in the bullet. amazon.co.uk has no customer-review line, so there is no star rating and no owner account of a hole. The page states a brushless motor, 2.5 kg, and 18 V, and it states neither impact energy nor a warranty. The speed cell says 1,500 rps, which is not an rpm figure you can use to plan a hole. Battery and charger are excluded, and the brand printed on the listing is NailHsing. At £34.67 the price is only a shelf price until reviews exist.
Pros
- Seller states Makita 18 V fit, tool only
- SDS plus and three modes, including chiselling, are listed
- Five bits are named in the bullet
- Shelf price £34.67
Cons
- No customer-review line on amazon.co.uk
- No impact energy and no warranty on the listing
- Speed cell says 1,500 rps
- Battery and charger are not included
Best for: You already own a Makita 18 V pack and you only want to see what this unreviewed seller listing claims.
Less suitable: You want owner reports of a hole in brick or concrete, or a hammer sold by Makita.

Common questions
Does this include a Makita battery?
No. The listing says tool only, and it tells you to confirm you already have a Makita 18 V battery. The brand on the listing is NailHsing.
Can it chisel?
The bullets say three modes: drilling, hammer drilling, and chiselling, with an SDS plus chuck.
How is it rated on Amazon?
This listing has no customer-review line, so the star rating and review count are not available.
How we compared
Eleven cordless rotary hammers on amazon.co.uk were scored on 19 October 2026 from listing facts and review notes, not from a lab test. Stars, sample size, fit for the job and value are weighted 40, 20, 25 and 15. Star points are the amazon.co.uk rating divided by 5, times 40. A listing with no review line scores 0. A joule figure or a hole count is the seller's claim unless a review describes that job. The 0–100 score is not a durability test.

Cordless rotary hammer buying guide
Start with the job size in joules, then the shank and the mode, then the battery family. A low shelf price on a bare tool comes after those three. The notes below follow that order for these eleven amazon.co.uk listings, checked on 19 October 2026. None of the scores is a hole drilled in a lab.
What is a cordless rotary hammer?
A cordless rotary hammer is a battery SDS drill with a pneumatic hammer, for brick, block and concrete when a combi drill's hammer setting stalls. Most household and light-trade tools are SDS plus. Compare joules and the battery family before brand names. Quality is a joule figure you can trace, a side handle, a hammer-only mode if you need to chisel, and a box that either includes the pack or says it does not. Job size comes first.
Best for
- Plug holes in brick after a combi stalled, if you already own the pack the body uses
- A first kit with a 4.0 Ah battery, a charger and a case, if you are not already on another 18 V family
- A Professional body with KickBack Control, if you read the maker's joules rather than a blank Amazon cell
Not ideal for
- Cores, breaking a slab, a full chase, or SDS max work at about 5 J and above
- A seller line that presents a third-party body as a Makita or DeWalt tool
- Anyone treating Amazon watts or torque on these rows as a checked capacity
Mistakes to avoid
- 1
Sorting by Amazon watts or torque
Several rows print watts or newton-metres that contradict the maker, including 1,765 Nm beside 15 Nm and a torque cell of 0.01 Nm. Those cells are not hole sizes. Sort on joules you can trace, the shank, and what the reviews say was drilled.
- 2
Comparing a bare tool with a two-battery kit
A body-only price leaves out the pack and the charger. The GBH 18V-22 X kit includes two 5.0 Ah batteries, a charger and an L-BOXX. Add that cost before you set a bare Ryobi or a bare Professional body beside it.
- 3
Mixing packs, or hammering the wrong bit
Blue Bosch Professional 18 V and green Bosch PBA 18 V do not share packs. A non-SDS bit is for rotary only. The GBH 18V-22 X manual says cylindrical and hex bits must not be hammered, even in a ONECHUCK. A 2 J tool is not a breaker.
What to weigh up
Joules, shank and mode
HighSDS Drill UK's rule of thumb is about 1.2–2 J for plug holes up to roughly 16 mm, about 2.5–3.5 J for larger anchors and regular chiselling, and about 5 J and above for SDS max. This category stops before SDS max. Bosch specifies the GBH 18V-22 X at 2 J, optimum 6–12 mm in concrete. Ryobi specifies the R18SDS-0 at 1.3 J, masonry to 16 mm. Several Amazon rows leave joules blank even when the maker publishes them. SDS plus bits are for hammer drilling. Rotary only is for wood and metal.
Battery family and the box
HighBlue Bosch Professional 18 V, green Bosch PBA 18 V, Ryobi ONE+ 18 V and Dong Cheng 20 V do not share packs. A line that says the body fits Makita 18 V, or DeWalt 18 V and 20 V MAX, is the seller's claim. The brand on those listings is NailHsing or ConBlom. Fit was not tested here. Read the scope line. The Ryobi R18SDS-0 and the Professional bodies in this set exclude the battery. The Dong Cheng kits include a 4.0 Ah pack and a charger.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
First kit with a battery
You do not already own a Ryobi or Bosch 18 V pack, and you want the battery, charger and case together. The Dong Cheng 2.1 J kit is about £79.99, with 4.5 from 100 reviews, a 4.0 Ah pack and a heavy-duty case.
A Professional body
You want a Bosch Professional body with KickBack Control, and you will read the maker's joules rather than a blank Amazon cell. The GBH 18V-22 X body is about £176.95, with 4.6 from 73 reviews. Bosch specifies this model at 2 J. The battery is not in the box.
Common questions about cordless rotary hammers
Which cordless rotary hammer is the top pick in this set?
The top pick is the Ryobi R18SDS-0, a ONE+ 18 V SDS plus body at about £90.29 on amazon.co.uk, with 4.7 from 2,755 reviews. The battery and charger are excluded. The listing states four modes, an LED and an impact stop, and it does not print joules. Ryobi specifies 1.3 J and masonry to 16 mm. Reviewers use it on concrete, brick and slate after a combi stalled. It can run hot on a long job. The score uses those listing facts and reviews. It is not a lab test.
Which cordless rotary hammer is the best value?
The best value is the Dong Cheng DCZC22 kit at about £79.99, with 4.5 from 100 reviews. The box includes a 4.0 Ah 20 V battery, a charger, four SDS plus bits and a heavy-duty case. The bullet states 2.1 J, a brushless motor and a hammer-only mode. Review notes cover brick, external walls and 8 mm holes in granite blocks. One charge lasted under five minutes and that unit was returned. It fits a first kit when you do not already own a Ryobi or Bosch 18 V pack.
How much does a cordless rotary hammer cost on amazon.co.uk?
On these eleven amazon.co.uk shelves, checked on 19 October 2026, prices run from about £34.67 to about £319.20. Entry mixes bare third-party bodies, Dong Cheng kits and a Ryobi body, up to about £99.99. Mid Bosch Professional bodies run from about £116.95 to about £176.95, and the green kit is about £132.60. The GBH 18V-22 X with two 5.0 Ah batteries, a charger and an L-BOXX is about £319.20. Add a pack and a charger before you compare a bare tool with a kit. These prices will move.
What should you check before you buy a cordless rotary hammer?
Start with the job. SDS Drill UK's rule of thumb is about 1.2–2 J for plug holes up to roughly 16 mm, and about 2.5–3.5 J for larger anchors and regular chiselling. About 5 J and above is SDS max. SDS plus bits are for hammer drilling. Rotary only is for wood and metal. Hammer-only is for light chiselling. Then match the battery family. A body-only price is low only when you already own that pack and a charger.
When is a combi drill the wrong tool for masonry?
A combi drill's hammer setting is for light masonry. Step up when that setting stalls in brick, block or concrete, or when the hole needs a pneumatic hammer and an SDS plus bit. A cordless rotary hammer covers plug holes and light chiselling. Breaking a slab is a different job, and about 5 J and above is SDS max. Ordinary combi drills are compared on their own page: combi drill.
Is a bare cordless rotary hammer cheaper than a kit?
A bare tool is the cheaper line only when you already own the right pack and a charger. Blue Bosch Professional 18 V, green Bosch PBA 18 V, Ryobi ONE+ 18 V and Dong Cheng 20 V do not share batteries. The Ryobi R18SDS-0 at about £90.29 excludes the battery. The Dong Cheng 2.1 J kit at about £79.99 includes a 4.0 Ah pack, a charger and a case. The GBH 18V-22 X kit at about £319.20 includes two 5.0 Ah packs and an L-BOXX. Compare the whole box.
When should you call a professional instead of drilling it yourself?
Call a professional for cores, breaking a slab, a full chase, suspected asbestos, work at height, or a day's concrete drilling without extraction and RPE. If a detector is unclear beside a cable or a pipe, stop. HSE sheet CN3 says concrete dust can contain respirable crystalline silica. Use capture at the bit where you can, and RPE of APF 20 when extraction is not used. Class M or H is the extraction class HSE names. Vibration and noise limits are employer duties.
Does a listing that says it fits Makita or DeWalt mean that brand?
The NailHsing listing is a NailHsing tool. It says the body runs on a Makita 18 V pack you already own, at about £34.67, and there is no customer-review line. The ConBlom listing says it takes DeWalt 18 V or 20 V MAX packs. The brand is ConBlom, at about £59.99, with 4.2 from 14 reviews. One reviewer, on an 18 V 5 Ah DeWalt pack and a 14 mm SDS plus bit, said it cut out after about five seconds. Fit was not tested here.
Our verdict
In this set of 11 amazon.co.uk listings, the top pick is the Ryobi R18SDS-0 body. It scores 86, at about £90.29, with 4.7 from 2,755 reviews. The listing is a ONE+ SDS plus body. The battery and charger are excluded. Four modes and an impact stop are listed. Reviewers use it on concrete, brick and slate after a combi has stalled. It runs hot on long jobs, and Amazon prints figures that cannot describe the hammer. The best value is the Dong Cheng DCZC22 2.1 J kit at about £79.99, with 4.5 from 100 reviews. The box includes a 4.0 Ah pack, a charger, four SDS plus bits and a case. One battery lasted under five minutes and was returned. The UniversalHammer body ties that kit on 81 and takes neither award. None of these scores is a lab test.
