A professional cordless combi drill is a battery drill with a keyless chuck, a clutch for screws and a mechanical hammer for masonry. In the UK you buy one for shelves, cabinets, light steel and occasional brick, when a lead is in the way and a rotary hammer is more machine than the hole. You tell a suitable one by the battery family first. A 12 V pack does not fit an 18 V tool, and a DIY-range pack does not fit a professional body. Read the carton next: a body only, or batteries, a charger and a case. If the shop table prints two torque figures, use the maker's stated torque and the stated diameters in wood, steel and masonry. A metal chuck, a brushless motor where it is stated, and a kickback cut-out are the stable checks. Hammer mode is a ratchet, not an SDS tool with impact energy in joules. Concrete lintels and repeated hard-brick holes need a rotary hammer. When that hammer is no longer enough is set out in the [combi drill or SDS guide](/hub/drilling-and-accessories/bosch-professional-cordless-combi-drill/sub/bosch-professional-cordless-combi-drill-vs-sds).

What is the job?
The best Bosch professional cordless combi drills in detail
Our view
The GSB 18V-65 kit lists two 5.0 Ah batteries, a GAL 18V-40 and an L-BOXX at £199.98, with 5.0 from only three UK reviews. Those three describe high torque for the size, an all-metal chuck, dual lights, a quick brake and a case that clips to other Bosch cases, and they say KickBack Control helps with hole saws. They also say the cut-out trips on a sharp movement when it is left switched on, and that a 5 Ah pack makes the tool noticeably heavier. One review describes two 4.0 Ah batteries and a charge of about two hours, which does not match the 5.0 Ah title, and notes that only one battery charges at a time. The torque cells print 55 Nm and 65 Nm, and the drill-type cell says basic drill. Three reviews and no described breakdown are not a large sample, so the five-star line does not outrank the 110 C body in this comparison.
Pros
- Title includes two batteries, a GAL 18V-40 and an L-BOXX
- Brushless motor, dual lights and KickBack Control on the listing
- Three UK reviews praise the chuck, the brake and hole-saw control
- Head length of 175 mm is printed in the title
Cons
- Only 3 reviews, so the 5.0 score is a very small sample
- Torque cells disagree at 55 Nm and 65 Nm
- One review describes 4.0 Ah packs, and KickBack can trip if left on
Best for: A compact brushless 18 V kit when you want batteries in the box and you can check the amp-hour marking on arrival.
Less suitable: You are choosing from review volume, or you need the stated 82 mm wood capacity of the 110 C.

Common questions
What batteries come with this GSB 18V-65 kit?
The title says two GBA 18V 5.0Ah batteries and charger GAL 18V-40, plus an L-BOXX. One of the three UK reviews says the box contained two 4.0 Ah batteries.
Does the listing include KickBack Control?
Yes. Special features list a brushless motor, dual working lights and KickBack Control. Reviews say the cut-out trips on a sharp movement when it is left on, and that it helps with hole saws.
How many UK reviews are written up?
The listing shows 5.0 from 3 reviews, and the notes contain three UK write-ups. That is too few to treat the score as a large sample.
Our view
Across 795 amazon.co.uk reviews at 4.7, the GSB 18V-110 C in the L-BOXX is the high-torque 18 V body in this set: the listing states 110 Nm, a 13 mm chuck, 82 mm in wood and 13 mm in metal, at £186.00 with no battery or charger. UK reviewers describe a brushless drill that handles screw, drill and hammer modes, including site work such as drilling and tapping stainless steel, on packs they already own. Special features name KickBack Control, a metal chuck, Bosch Professional 18 V compatibility and AMPShare. Bluetooth is listed as a connectivity option and is not in the included line, so the included line does not show the module in the box. One buyer found the tool too fast for ordinary screwdriving unless the screw meets little resistance, and another did not keep it because it was more professional than they wanted. A further review describes a unit that arrived opened and looking used, which points at the seller rather than a design fault. It is the top pick here when you already have Professional 18 V batteries and want this torque class in an L-BOXX, not a first kit for light cabinet work.
Pros
- Listing states 110 Nm, a 13 mm chuck, 82 mm in wood and 13 mm in metal
- 4.7 from 795 amazon.co.uk reviews
- L-BOXX 136 and auxiliary handle, body only
- KickBack Control and a brushless motor named on the listing
Cons
- No battery or charger at £186.00
- Too quick for easy screws in one UK review
- Bluetooth module is not shown as included
Best for: Site and workshop jobs on Bosch Professional 18 V packs you already own, when you want the 110 Nm class and a stacking L-BOXX.
Less suitable: A first drill, overhead cabinet work, or anyone who needs batteries and a charger in the box.

Common questions
Does the GSB 18V-110 C in the L-BOXX include a battery?
No. The amazon.co.uk title for B083QMJR8Y says the tool is without a battery and charger. The included line lists the GSB 18V-110 C and L-BOXX 136, and the bullets add auxiliary handle 1 602 025 07X.
Is KickBack Control on this listing?
Yes. Special features name KickBack Control, a brushless motor, a solid metal chuck, Bosch Professional 18 V compatibility and AMPShare.
Is the Bluetooth module in the box?
The listing calls Bluetooth a connectivity option. It is not in the included-components line, so the listing does not show the module as supplied.
Our view
The 12 V set pairs a GSB 12V-15 with a GDR 12V-105 impact driver, two 2.0 Ah batteries, a GAL 12V-40 and a bag, at £239.99 and 4.7 from 305 reviews. UK reviewers praise the size for kitchens and tight spaces, the second battery, and an impact driver they use on long screws, decking and furniture, and several say it is the set to choose when an 18 V drill feels heavy. The same file records a bag that started falling apart, a charger that did not work, bits falling out of the driver, an impact driver that died after a few minutes, hammer feel in every mode, and a returned drill with about 0.75 mm of chuck run-out. The listing prints one torque of 120 Nm for the whole set and a maximum speed of 2.6 rpm, which are conflicts rather than capacities you can quote. It suits overhead and cabinet work on the separate 12 V system, not the heaviest site drilling and not as a way into 18 V packs.
Pros
- Combi and impact driver, two 2.0 Ah batteries, charger and bag
- 4.7 from 305 reviews, with praise for kitchens and tight spaces
- Reviewers recommend it when 18 V feels too heavy
- 24-month warranty line on the listing
Cons
- £239.99, and the packs are a 12 V family, not 18 V
- UK reviews describe a failed bag, a dead charger, a dead impact driver and chuck run-out
- One 120 Nm cell and a 2.6 rpm speed cell do not split the two tools
Best for: Overhead and cabinet fitting on the Bosch Professional 12 V system, when you want a combi and an impact driver together.
Less suitable: Heaviest site drilling, or anyone who already owns 18 V packs and expects them to click on.

Common questions
What is in the 12 V set?
The title lists cordless combi drill GSB 12V-15, impact driver GDR 12V-105, two 2.0 Ah batteries, charger GAL 12V-40 and a bag.
Does 120 Nm apply to the combi drill?
The listing prints one torque of 120 Nm and does not say whether it is the GSB 12V-15 or the GDR 12V-105. It also prints a maximum speed of 2.6 rpm. Both figures are listing conflicts.
What went wrong in UK reviews?
Reviews mention a bag that fell apart, a charger that did not work, bits falling out of the impact driver, an impact driver that died, hammer feel in every mode, and a returned drill with about 0.75 mm of chuck run-out. Other reviews praise the size for kitchens and tight spaces.
Our view
The GSB 18V-65 body is £84.99 with an L-BOXX and no battery or charger, at 4.7 from 35 reviews. The UK notes contain one write-up, which says the tool will be excellent because it is made by Bosch and does not describe a feature or a fault. The title states a 175 mm head, the bullets name a brushless motor and switchable KickBack Control, both torque cells say 55 Nm, and a bullet says 65 Nm. The chuck cell also prints 175 mm, the same figure as the head length, so that cell is not a jaw size you can use. Listed weight is 1.1 kg, which makes this the light compact 18 V body in the table and the lowest shelf price. It is the best value if you already own Professional 18 V packs and you treat the thin UK review text as a limit, not if you need batteries in the carton.
Pros
- Lowest price in the set at £84.99, with an L-BOXX
- 4.7 from 35 reviews
- Brushless motor and a 175 mm head length in the title
- Bullet lists switchable KickBack Control
Cons
- No battery or charger
- Only one UK review written up against a count of 35
- Chuck cell prints 175 mm, and the torque cells and bullet disagree
Best for: An owner of Bosch Professional 18 V batteries who wants a compact brushless body and a case at £84.99.
Less suitable: A first kit with no packs, or a buyer who needs a chuck size and a torque figure the listing states once.

Common questions
Does this GSB 18V-65 include a battery?
No battery or charger is named. Included components are the GSB 18V-65 and an L-BOXX. A bullet lists the scope as one L-BOXX.
Why does the chuck say 175 mm?
The specification row prints maximum chuck size 175 millimetres. The title prints head length 175. Those are the same figure, so the row is not a jaw size.
Is KickBack Control listed?
A bullet says switchable KickBack Control and dual working lights. The special-features cell only names a brushless motor and a built-in LED work light.
Our view
The cardboard GSB 18V-110 C is the same 110 Nm class at £149.99, rated 4.6 from 222 reviews, sold as a body with the auxiliary handle and no battery or charger. UK reviewers say it is faster in stone, slab and brick than an older corded Bosch, and that existing Professional 4 Ah packs run it without a ProCORE battery. The side handle is treated as necessary because the tool can twist hard, and one reviewer went back to an older drill for large screws when second gear slipped. Chuck complaints are specific on this ASIN: one calls the chuck crunchy and hard to tighten, another says the bit fell out and the chuck then jammed shut after two days, and a third says the bit falls out nearly every time. The dimensions cell prints 12.7 × 10.4 × 4.5 cm, which is too small for this body, so it is only the figure the listing prints. Choose it if you want the 110 Nm class without paying for the L-BOXX and you will check the chuck on arrival.
Pros
- £149.99 for the 110 Nm body and auxiliary handle
- 4.6 from 222 reviews, with praise for brick and existing 4 Ah packs
- Listing states a 13 mm chuck, 82 mm in wood and two speeds
- Brushless motor named in the bullets
Cons
- No battery, charger or case
- UK reviews describe a crunchy chuck, bits falling out and one chuck that jammed
- Dimension cell of 12.7 × 10.4 × 4.5 cm is not a usable body size
Best for: An 18 V owner who wants the 110 Nm class in cardboard and will test the chuck before the first job.
Less suitable: You need an L-BOXX, batteries in the carton, or a listing whose UK reviews do not describe chuck grip failures.

Common questions
Does this cardboard GSB 18V-110 C include batteries?
No. Model 06019G0309 is described as excluding rechargeable batteries and a charger. The scope line is the auxiliary handle and a cardboard box.
What do UK reviews say about the chuck?
One review calls the chuck crunchy and hard to tighten. Another says the bit fell out and the chuck then jammed shut. A third says the bit falls out after use. The listing still shows 4.6 from 222 reviews.
Why is the size 12.7 by 10.4 by 4.5 cm?
That is the item-dimensions line on the listing. It is too small for this drill body, so it is a printed figure rather than a measured size.
Our view
The GSB 18V-25 kit is £149.99 with two 4.0 Ah batteries, a GAL 18V-40 charger and an L-Case, at 4.6 from 141 reviews. UK reviewers use it for TV mounts, shelves, light switches and a garage extension, and they call the build a step up from a green home-and-garden drill, with a metal chuck that held in one detailed write-up. The same reviews say the motor is brushed, that the L-Case will not lock onto an L-BOXX, and that green Bosch batteries did not fit, so one buyer returned it. The specification row prints both 60 Nm and 10 Nm, a 10 mm chuck, three speeds and 10 mm in wood, while a bullet talks about screws from 10 mm up to 35 mm. One review says a battery was not supplied, against a title that includes two packs. It is the complete 18 V kit in this set for household holes and screws if you accept a brushed motor and those conflicting cells.
Pros
- Two 4.0 Ah batteries, GAL 18V-40 and an L-Case in the title
- 4.6 from 141 reviews for household fitting work
- Metal chuck praised for grip in one UK review
- AMPShare and Professional 18 V named on the listing
Cons
- UK reviews describe a brushed motor and point at higher GSB models
- L-Case does not lock to an L-BOXX
- Torque cells print 60 Nm and 10 Nm, and green batteries do not fit
Best for: A first blue 18 V kit for shelves, switches and light building work, when you do not already own packs.
Less suitable: You want a brushless high-torque body, an L-BOXX that stacks, or you already own green POWER FOR ALL batteries.

Common questions

The title and the included-components line say two GBA 4.0Ah batteries and a GAL 18V-40 charger are included, plus an L-Case Pick & Click. One UK review says a battery was not supplied.
Will green Bosch batteries fit this drill?
A verified UK review says home-and-garden batteries did not fit and the drill was returned. The listing points AMPShare and the Bosch Professional 18V System, which is the blue system.
Why do the torque figures disagree?
The raw specification row prints maximum torque 60 Nm and a second torque field of 10 Nm. It also prints a 10 mm chuck, three speeds and 10 mm wood capacity. Those cells are what the row prints.
How we compared
Six Bosch Professional cordless combi drills on amazon.co.uk were scored from the listings and the UK review notes, not from a lab test. The amazon.co.uk star line is the base. Sample size, a conflicting specification cell and a UK defect note are deductions. Value is used only to choose best value, and it is not added to the score. The top pick is excluded from that badge. Shelf prices, stars and review counts are the figures for this set on 19 October 2026.
1
Amazon star line
55%The amazon.co.uk star rating times 20 is the base. A 4.7 becomes 94. A 5.0 becomes 100. The star line printed on each row stays the listing figure.

Listing conflict
15%Applied once, minus 4, when specification cells contradict each other or print a figure that cannot be the part they name. That covers a torque pair, a chuck cell that repeats the head length, and a speed cell of 2.6 rpm.

UK review notes
10%A defect cluster is minus 4 when more than one UK write-up describes a failed part. A single mild issue is minus 2 when the note is seller condition, a contents mismatch, or a behaviour the listing already warns about. There is no separate support score.

Bosch professional cordless combi drill buying guide
Start with the battery family, then what is in the carton, then the torque class from Bosch Professional when the amazon.co.uk table prints two figures. The notes below follow that order for these six listings, checked on 19 October 2026. None of the scores is a drilling test.
What is a Bosch professional cordless combi drill?
A Bosch Professional cordless combi drill in this set is a blue GSB: a keyless chuck, a clutch for screws, and a mechanical hammer for masonry, on the 12 V or the 18 V Professional battery system. UK buyers on amazon.co.uk are choosing between compact 18 V bodies, a high-torque GSB 18V-110 C sold without batteries, and a 12 V set that pairs a GSB 12V-15 with a GDR impact driver.
Best for
- Tradespeople who already own blue 18 V or AMPShare packs and need the 110 C's stated capacity
- A first blue 18 V kit, if you will not assume green batteries fit
- Overhead and cabinet fitting, where the 12 V set is the lighter option
Not ideal for
- Concrete lintels and repeated holes in hard brick
- Anyone comparing a bare-tool price with a kit as if a battery were included
- A buyer who needs every amazon.co.uk torque cell to match the maker's figure
Mistakes to avoid
- 1
Putting green batteries on a blue drill
POWER FOR ALL packs do not fit Professional 18 V or 12 V tools. A UK review of the GSB 18V-25 kit says home-and-garden batteries did not fit and the drill was returned. A 12 V pack does not click onto an 18 V body.
- 2
Comparing a bare price with a kit
The GSB 18V-65 body at about £84.99 and both GSB 18V-110 C bodies have no battery and no charger. The 18V-25 kit, the 18V-65 kit and the 12 V set do. The lower shelf price is not the cheaper job if you still have to buy packs.
- 3
Trusting a conflicting cell, or hammering a lintel
Do not treat 120 Nm or 2.6 rpm on the 12 V set as the combi's capacity, or 175 mm as a chuck size when that figure is the head length. Hammer mode is a ratchet. Concrete lintels and repeated hard-brick holes need an SDS rotary hammer.
What to weigh up
Battery family and box contents
HighBlue 18 V and AMPShare packs fit 18 V GSB tools back to 2008. Professional 12 V packs fit the 12 V set, including older 10.8 V Professional tools since 2005. Green POWER FOR ALL packs fit neither. The bare GSB 18V-110 C listings and the bare GSB 18V-65 have no battery and no charger. The GSB 18V-25 kit includes two 4.0 Ah packs and a GAL 18V-40. The GSB 18V-65 kit includes two 5.0 Ah packs, though one of three UK reviews describes 4.0 Ah packs.
Torque class, chuck and hammer
HighUse the Bosch Professional figure when the amazon.co.uk row disagrees with itself. The GSB 18V-110 C is up to 110 Nm, 82 mm in wood, 13 mm in steel and 16 mm in masonry, about 1.9 kg without a battery. The GSB 18V-65 highlight is 31/65 Nm, with 76 Nm also on the data table, a 175 mm head and 13 mm in masonry. The GSB 18V-25 manual states 56/21 Nm, 35 mm in wood and 10 mm in masonry and steel. The GSB 12V-15 is 30/15 Nm and 10 mm in masonry.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
A first blue 18 V kit
You do not own packs yet, and green batteries will not fit. The GSB 18V-25 kit is about £149.99 with two 4.0 Ah batteries and a charger, at 4.6 from 141 reviews. UK reviews call the motor brushed.
Overhead and cabinet fitting
An 18 V body feels heavy overhead. The 12 V set pairs a GSB 12V-15 with an impact driver, two 2.0 Ah packs and a charger, at about £239.99 and 4.7 from 305 reviews. Those packs do not fit an 18 V tool.
Common questions about Bosch professional cordless combi drills
Which Bosch professional cordless combi drill is the top pick in this set?
The top pick is the Bosch GSB 18V-110 C in an L-BOXX, about £186.00 on amazon.co.uk, with 4.7 from 795 reviews. The listing states 110 Nm, a 13 mm chuck, 82 mm in wood and 13 mm in metal, plus KickBack Control and a brushless motor. No battery or charger is included. Two points came off for a unit that arrived opened and for reviews that call it too fast for easy screws. The score is not a lab test.
How much do these Bosch professional cordless combi drills cost?
On these six amazon.co.uk shelves, checked on 19 October 2026, prices run from about £84.99 to about £239.99. The GSB 18V-65 body is about £84.99. The cardboard GSB 18V-110 C and the GSB 18V-25 kit are about £149.99. The GSB 18V-110 C in an L-BOXX is about £186.00. The GSB 18V-65 kit is about £199.98. The 12 V set is about £239.99. A bare body does not include a battery. These figures are this set only, and they will move.
Will green Bosch batteries fit a professional combi drill?
No. Green POWER FOR ALL packs do not fit blue Professional tools, and a 12 V pack does not fit an 18 V body. Blue 18 V and AMPShare packs fit 18 V GSB tools back to 2008. Professional 12 V packs fit the 12 V set, including older 10.8 V Professional tools since 2005. A UK review of the GSB 18V-25 kit says home-and-garden batteries did not fit and the drill was returned. Match the family you already own before you compare a bare price with a kit.
What should you check before you buy?
Start with the battery system, then the carton, then the torque class. A body-only listing has no battery and no charger. Use the Bosch Professional figure where amazon.co.uk prints two: up to 110 Nm on the 18V-110 C, the 65 Nm class on the 18V-65, 56/21 Nm in the 18V-25 manual, and 30/15 Nm on the GSB 12V-15. Do not read a chuck cell of 175 mm as a jaw size. Do not read 120 Nm on the 12 V set as the combi's torque.
Is hammer mode the same as an SDS drill?
No. Hammer mode on a GSB is a ratchet. Concrete, engineering brick and repeated holes above about 10 mm need an SDS-plus rotary hammer, which states impact energy in joules. One reviewer of the GSB 18V-110 C keeps an SDS tool for heavy hammering. A cordless rotary hammer is a different comparison: rotary hammer. This page did not test these combis in concrete lintels.
Should you buy 12 V or 18 V?
Choose 18 V if you already own Professional 18 V or AMPShare packs and you need the stated capacity of the 110 C, or a compact 65. Choose the 12 V set for overhead and cabinet work, when an 18 V body feels heavy. That set pairs a GSB 12V-15 with a GDR 12V-105 impact driver, two 2.0 Ah packs, a charger and a bag, at about £239.99. Those packs do not click onto an 18 V tool. The listing's 120 Nm cell is not split between the two tools.
What went wrong in the UK reviews?
On the cardboard GSB 18V-110 C, UK reviews describe a crunchy chuck, bits falling out and one chuck that jammed. On the 12 V set, reviews describe a bag that fell apart, a charger that did not work, a dead impact driver and about 0.75 mm of chuck run-out. On the GSB 18V-65 kit, one of three reviews describes 4.0 Ah packs against a 5.0 Ah title, and KickBack Control can trip if it is left on. These notes are not a measured failure rate.
When should you call a professional?
Call a professional for structural fixings, unknown services in the wall, a jammed chuck, or an employee vibration assessment above the action value of 2.5 m/s² A(8). The limit value is 5 m/s² A(8). Declared impact vibration is 12.8 m/s² on the GSB 18V-25 in concrete and 15.5 m/s² on the 110 C in masonry. The 18V-25 manual says wear ear protectors when impact drilling. A battery combi is not automatically quieter or lower-vibration than a mains tool. This page is not that assessment.
Our verdict
In this set of six amazon.co.uk listings, the top pick is the Bosch GSB 18V-110 C in an L-BOXX, about £186.00, with 4.7 from 795 reviews. The listing states 110 Nm, a 13 mm chuck, 82 mm in wood and 13 mm in metal, KickBack Control and a brushless motor, and no battery or charger. Two points came off for a unit that arrived opened and for reviews that call it too fast for easy screws. The best value is the Bosch GSB 18V-65 body with an L-BOXX at about £84.99, with 4.7 from 35 reviews. It is brushless, with no battery. The chuck cell prints 175 mm, the same figure as the head length, so that cell is not a jaw size. The other four have no award. None of these scores is a lab test.
