The best Bosch professional SDS drills, compared.
Top pick: Bosch Professional GBH 2-21 (110 V) Best value: Bosch Professional GBH 18V-18 – Close to the corded kit at about £122.95, with 4.6 from 141, if you already own a Bosch Professional 18 V or AMPShare pack. A new battery removes that saving, and there is no chisel mode. Updated October 2026.
A professional SDS drill is a rotary hammer with an SDS-plus holder. You buy one in the UK when a combi drill stalls in brick, block or concrete. Judge a suitable one by impact energy in joules, the concrete diameter, whether a chisel mode exists, and the supply: an 18 V body, 230 V at a domestic socket, or 110 V on site. The holder should click an SDS-plus bit. Some holders also clamp a straight or hex shank. SDS-max bits do not fit. A cordless body without a battery is not a kit you can use the same day. A 110 V tool needs a transformer and will not plug into a BS 1363 socket. A 230 V lead at home wants an RCD. Declared hammer-drilling vibration often sits well above the action value of 2.5 m/s² A(8). Concrete dust can contain respirable crystalline silica, so plan extraction or suitable respiratory protection, and fit the side handle. How to read joules, modes and the box is set out in the [professional SDS drill buying guide](/hub/drilling-and-accessories/bosch-professional-sds-drill/sub/bosch-professional-sds-drill-buying-guide).

Question 1 of 2
How will you power it?
This GBH 2-21 listing, order 06112A6061, is titled as 110 V and priced at about £134.99, with a case and 6 mm, 8 mm and 10 mm SDS-plus bits. The specification table on the same page says 220 V and 14 A, so the supply is not agreed, and those table figures are not used. amazon.co.uk shows 5.0 from 3 ratings. Two written reviews are short and positive, and neither describes a fault. The listed weight is 2.93 kg, against 2.3 kg on the 230 V listing, so that line is not a settled spec. Three ratings cannot show whether the tool fails. The bullets still state 2.0 J with hammer drilling, drilling and chiselling. It will not plug into a BS 1363 socket.
Pros
Cons
Best for: You already have 110 V centre-tapped site power and you will confirm the live page is the 110 V tool before you pay.
Less suitable: You are plugging into a BS 1363 socket at home, or you want a review sample larger than three ratings.
Specifications
Common questions
Is this the 110 V GBH 2-21?
The title says 110 V and the model number is 06112A6061. The specification table on the same listing says 220 V and 14 A, so the two fields conflict. Confirm the live page before you pay, and do not treat 220 V or 14 A as the spec.
Does the listing say it chisels?
Yes. The bullets describe hammer drilling, drilling and chiselling, and a case with three SDS-plus bits is included. The impact line in the bullets is 2.0 J.
Can you plug it into a home socket?
No. A 110 V tool needs a transformer and will not plug into a BS 1363 socket. HSE expects site portable tools to be cordless or 110 V centre-tapped to earth. At home, the 230 V GBH 2-21 is the listing whose title and table agree.
This GBH 18V-22 X, order 0611924102, adds an L-BOXX 136 and an inlay to the ONECHUCK hammer and is listed at about £232.73, against about £176.95 for the carton listing of the same model family. The weight line is 2.37 kg, which differs from 2.52 kg on that carton listing. amazon.co.uk shows 4.8 from 45 ratings. None of the written reviews in the file is from the United Kingdom. One of them says the keyless cylindrical section failed after about 15 holes while SDS-plus still worked. A battery is still not included. Bosch states 2.0 J for the GBH 18V-22 X. KickBack Control, Vibration Control and a brushless motor are stated, and the listing does not state impact energy.
Pros
Cons
Best for: You want the GBH 18V-22 X stored in an L-BOXX and you already own the battery.
Less suitable: You need UK-written reviews, or you can live with a carton and spend the difference on a pack.
Specifications
Common questions
What do you pay extra for versus the carton GBH 18V-22 X?
This ASIN adds an L-BOXX 136 and an inlay. The shelf price is about £232.73 against about £176.95 for the carton listing. A battery is still not included. The listed weight is 2.37 kg, against 2.52 kg on the carton listing.
Are there UK reviews in the file?
No. The 4.8 score from 45 ratings is on the listing. The written reviews in the file are from Spain, Germany, France and Italy, so they are not UK evidence for how the tool behaves here.
What failed in one review?
A reviewer said the ONECHUCK keyless section failed after about 15 holes, while SDS-plus still worked. That review is not from the United Kingdom. It is one report, not a failure rate.
The GBH 18V-22, order 0611924001, is an 18 V SDS-plus hammer at about £180.99 with an L-BOXX 136, an inlay, a depth gauge and a cloth, and no battery or charger. amazon.co.uk shows 4.6 from 523 ratings, the largest sample in this set. Reviewers describe it replacing a hard-used Bosch SDS for lighter daily work, including kitchen and bathroom fitting, and they praise KickBack Control when a bit binds. They also say it is not the equal of a 110 V site SDS for hard work. Bosch’s UK page states 1.9 J and about 2.3 kg without a battery, and it describes chiselling, while the amazon listing leaves impact energy blank and prints 850 W on a battery tool. The title points at holes of 6 mm to 10 mm.
Pros
Cons
Best for: You already own Bosch Professional 18 V or AMPShare packs and you fit kitchens and bathrooms with holes around 6 mm to 10 mm.
Less suitable: You need a tool that drills the day it arrives without buying a battery, or you want all-day breaking.
Specifications
Common questions
Does this GBH 18V-22 include a battery?
No. The box is the tool, an L-BOXX 136, an inlay, a cloth and a depth gauge. Reviewers flag the missing battery and charger. The shelf price is about £180.99 without that pack.
Which batteries does the listing name?
Bosch Professional 18 V and the AMPShare shared system. A GDE 18V-12 or GDE 12 extractor is mentioned as an attachment, not as included. Bosch states 1.9 J for this model.
What hole size does the title suggest?
The title says it is ideal for drilling 6 mm to 10 mm holes. Listed wood and metal capacity is 10 mm. Impact energy is absent from the amazon file, so the 1.9 J figure is the Bosch UK page.
This is the GBH 18V-18, order 0611927000, a body-only 18 V SDS-plus hammer listed at about £122.95 and 1.59 kg. The box is a cardboard carton, a depth gauge and an auxiliary handle, with no battery, charger or case. amazon.co.uk shows 4.6 from 141 ratings. Reviewers say the small body still drills solid concrete. Bosch’s UK page for this order states 1.5 J and describes hammer drilling and non-impact drilling, not a chisel function, while the amazon listing leaves impact energy blank. One unit arrived with a stuck mode selector and was replaced, and one reviewer could not release a bit. The listing’s 50 mm chuck and 80 Nm conflict with a compact SDS-plus hammer, so those figures are not used.
Pros
Cons
Best for: You already own a Bosch Professional 18 V pack and you want a light hammer for fixings rather than chasing.
Less suitable: You need to chisel, you have no battery yet, or you want a case in the box.
Specifications
Common questions
Are a battery and a case included?
No. The scope of supply is a cardboard box, a depth gauge and an auxiliary handle. A reviewer wished a case had been included. You need a Bosch Professional 18 V or AMPShare pack you already own.
Does the GBH 18V-18 have a chisel mode?
No. Bosch’s UK page describes hammer drilling and non-impact drilling, not a chisel function. Chiselling is not a stated feature on the amazon.co.uk listing either.
Why is chuck size not shown in the table?
The listing says 50 mm, and it also prints 80 Nm. Both conflict with a compact SDS-plus hammer, so neither figure is used. Bosch states 1.5 J for this order.
The GBH 2-21 on this listing, order 06112A6071, is a corded SDS-plus hammer at about £120.15, and both the title and the specification table say 230 V. The bullets state 2.0 J, 720 W and 2.3 kg, with hammer drilling, drilling and chiselling, plus a case, 6 mm, 8 mm and 10 mm SDS-plus bits, a side handle and a depth stop. Across 122 amazon.co.uk ratings it sits at 4.6. UK reviewers describe it going into concrete and breeze block after a cordless combi stalled, and they use extra chisels for chasing and for lifting coving. One buyer called it heavy, then found the weight manageable for work at height. The listing gives speed as both 1200 rpm and 720 rpm, so that figure is not settled. In the UK reviews in the file there is no repeated mechanical failure.
Pros
Cons
Best for: You want a corded hammer for fixings and light chasing at home, and you can plug into 230 V.
Less suitable: You need 110 V site power, a battery tool, or long sessions breaking hard concrete.
Specifications
Common questions
Does this GBH 2-21 chisel?
The listing bullets say it is a three-mode rotary hammer for hammer drilling, drilling and chiselling. That is the 230 V listing, order 06112A6071, not the 110 V title.
What comes in the box?
A carrying case, SDS-plus bits in 6 mm, 8 mm and 10 mm, an auxiliary handle, a machine cloth and a depth stop. It is a corded tool, so there is no battery.
What mains supply does the listing state?
Both the title and the specification table say 230 V. Use it on a UK socket with an RCD. Speed is listed as both 1200 rpm and 720 rpm, so that line is not settled.
The GBH 18V-22 X, order 0611924100, is the ONECHUCK body in a carton at about £176.95, listed at 2.52 kg, with a depth gauge and an auxiliary handle and no battery or case. amazon.co.uk shows 4.6 from 73 ratings. UK reviews praise masonry drilling with a positive SDS click, and one of them used the chisel on tiles. The feature bullets do not state a chisel mode, so that use sits in the reviews rather than the specification. Bosch’s UK page for the GBH 18V-22 X states 2.0 J and does describe chiselling, which the amazon file does not. Battery life depends on the pack you add. KickBack Control, Vibration Control and a brushless motor are stated.
Pros
Cons
Best for: You want ONECHUCK on the GBH 18V-22 size, you already have a pack, and you do not need an L-BOXX.
Less suitable: You want the case included, or you need the listing itself to state a chisel mode before you buy.
Specifications
Common questions
How is this different from the GBH 18V-22?
This listing is the GBH 18V-22 X with ONECHUCK, so SDS-plus, cylindrical and hex bits fit one holder. The box is a carton, not an L-BOXX, and a battery is not included. Bosch states 2.0 J for the X model, against 1.9 J for the GBH 18V-22.
Is dust extraction included?
No. The bullets name an optional GDE 18V-12 or GDE 12 attachment. The scope is the carton, a depth gauge and an auxiliary handle. Concrete dust still needs extraction or suitable respiratory protection.
Do the UK reviews mention chiselling?
Yes. One UK review used the chisel on tiles. The feature bullets themselves do not state a chisel mode. Bosch’s UK page for the GBH 18V-22 X does describe chiselling.
The GBH 2-28, order 0611267571, is the corded hammer at about £253.21. The bullets state 3.2 J, and the listed weight is 3.24 kg. The title says 240 V and 880 W, and the table says 230 V and 850 W. The box includes an L-BOXX 136, an inlay, a side handle, a 210 mm depth stop and a cloth. amazon.co.uk shows 4.4 from 20 ratings. Reviewers praise heavy-duty holes in tough walls, balance, and neat holes in granite. They also call it loud and heavier than a previous drill. One report describes a failure after about six months while chiselling soft brick, which is one review rather than a failure rate. KickBack Control and Vibration Control are stated. The warranty line is two years plus one year if you register.
Pros
Cons
Best for: You plug in on a 230 V supply and you need the 3.2 J hammer for harder concrete and chiselling.
Less suitable: You work overhead for long spells, you need 110 V, or you want a large review sample.
Specifications
Common questions
What impact energy does the listing state?
The bullets say 3.2 J. Bosch’s UK page for order 0611267571 also states 3.2 J and a concrete range of 4–28 mm. The listed weight is 3.24 kg. The sample is 4.4 from 20 ratings.
Why do the watts and volts not match the title?
The title says 240 V and 880 W. The specification table says 230 V and 850 W. Both are recorded, and neither is corrected here. It is a corded tool for a UK socket with an RCD, not a 110 V site lead.
Does it come with a case?
Yes. The scope includes an L-BOXX 136, an inlay, an auxiliary handle, a 210 mm depth stop and a machine cloth. KickBack Control and Vibration Control are stated on the listing.
The GBH 18V-18 X, order 0611927100, is the ONECHUCK version of the compact 18 V hammer, listed at about £116.95 and 1.8 kg, tool only. The bullets say the holder takes SDS-plus, cylindrical and hex bits, with wood and metal capacity stated at 10 mm. amazon.co.uk shows 4.3 from 55 ratings. Reviewers call it very light and say straight and SDS bits change in seconds. The same thin set includes a tool called underpowered in soil and a bit that stuck after one use. Bosch’s published figure for this compact X model is 1.5 J with no chisel mode. The listing omits impact energy and lists torque as both 35 Nm and 5 Nm. There is no battery in the box.
Pros
Cons
Best for: You want one holder for SDS-plus and straight bits, you already have an 18 V pack, and the holes stay small.
Less suitable: You are chasing or breaking out, or you are buying your first battery with this tool.
Specifications
Common questions
Which bits fit the GBH 18V-18 X?
The bullets say the ONECHUCK takes SDS-plus, cylindrical and hex bits. Listed wood and metal capacity is 10 mm. Bosch limits straight shanks to 10 mm on this model. SDS-max bits do not fit.
Is a battery included?
No. The included-items line is the GBH 18V-18 X only. The listing says it runs on an 18 V pack of 2.0 Ah or higher. A case is not stated.
Does the listing promise chiselling?
No. KickBack Control and Vibration Control are stated. A chisel mode is not. Bosch’s figure for this compact X model is 1.5 J, and the listing omits impact energy.
Eight Bosch professional SDS drills on amazon.co.uk were scored on 19 October 2026 from listing facts, review notes and Bosch UK pages where a listing omits impact energy. Amazon evidence is weighted 35, listing and Bosch fit 40, and value 25. A body-only price is not scored as a working kit. A 110 V title loses points when the same page prints another voltage. This is not a lab test.
Amazon evidence
35%Stars are scaled out of 20, then a review-count band out of 15. Points come off for fewer than 10 ratings, no UK review text in the file, and a repeated or early failure.
Listing and Bosch fit
40%Impact energy counts when the listing or the Bosch UK page states it, along with clear modes, a clear holder, a supply line that does not contradict itself, a case or L-BOXX, and KickBack Control or Vibration Control when stated.
Value
25%Value is what you can do on the day it arrives for the GBP shelf price. A body-only price loses points because the battery is a separate purchase. A conflicting voltage on the same page loses points too.
Start with impact energy and the concrete diameter, then the modes and the holder, then the supply and what is actually in the box. Vibration and dust come before you treat a low body-only price as a finished kit. The notes below follow that order for these eight amazon.co.uk listings, checked on 19 October 2026. None of the scores is a lab test.
A Bosch Professional SDS drill in this comparison is a blue rotary hammer with an SDS-plus holder. You buy it to hammer-drill brick, block and concrete, and on some models to chisel. Judge a listing by impact energy in joules, the concrete diameter, whether a chisel mode exists, the supply, and the declared vibration. On amazon.co.uk in this set the shelf prices run from about £116.95 for a compact 18 V body to about £253.21 for the corded GBH 2-28.
Every cordless listing here omits the battery and charger. Some add an L-BOXX, a side handle and a depth stop. Bosch says these 18 V hammers run on Professional 18 V packs from 2008 and on AMPShare packs. A body-only price is not a working kit.
Bosch’s GBH 18V-18 manual describes hammer drilling and non-impact drilling or screwdriving, not a chisel function. The same limit applies to the GBH 18V-18 X. Chiselling is described for the GBH 18V-22 and GBH 18V-22 X, and the GBH 2-21 listing states three modes.
Do not use the GBH 18V-18 listing’s 50 mm chuck or 80 Nm, or the 110 V GBH 2-21 table’s 220 V and 14 A. Do not buy 110 V with no transformer. A 110 V tool will not plug into a BS 1363 socket.
Impact energy, stated by Bosch to EPTA 05/2016, is the first split. The GBH 18V-18 and 18V-18 X are 1.5 J, for holes about 4–18 mm, and neither has a published chisel mode. The GBH 18V-22 is 1.9 J, the GBH 18V-22 X and the GBH 2-21 are 2.0 J, and the GBH 2-28 is 3.2 J with a concrete range of 4–28 mm. Several cordless listings leave joules blank, so the Bosch UK page is the figure used here, not a chuck size or a torque line that conflicts with it. Modes are the second split.
Supply decides whether the tool works on the day it arrives. A 230 V GBH 2-21 uses a UK socket with an RCD. The 110 V title needs a transformer and will not plug into a BS 1363 socket, and that listing’s table also prints 220 V, so confirm the live page. Every 18 V listing here is a body. Bosch says these hammers run on Professional 18 V packs from 2008 and on AMPShare packs.
Three typical situations, each with a recommendation from this comparison.
You already own a combi drill and now need concrete fixings or a short chase, and you can plug in at 230 V with an RCD. The GBH 2-21 kit is about £120.15, with 2.0 J, three modes, a case and three bits, and 4.6 from 122 ratings.
You want a hammer without a lead and you already own a Bosch Professional 18 V or AMPShare pack. The GBH 18V-18 body is about £122.95, with 4.6 from 141 ratings. It is 1.5 J, it does not chisel, and the box has no battery.
A 230 V lead is often refused on site. The GBH 2-21 title at about £134.99 says 110 V, order 06112A6061, but the same page prints 220 V, and the sample is 5.0 from 3 ratings. Confirm the live page, and plan a transformer. It will not plug into a BS 1363 socket.
In this set of eight amazon.co.uk listings, the top pick is the Bosch Professional GBH 2-21 230 V kit, order 06112A6071, at about £120.15, with 4.6 from 122 ratings. The listing states 2.0 J, three modes, a case and three SDS-plus bits, and the title and the table both say 230 V. Speed is listed twice, so that line is ignored. The best value is the GBH 18V-18 body, order 0611927000, at about £122.95, with 4.6 from 141 ratings, and only if you already own a Bosch Professional 18 V or AMPShare pack. It has no battery, no case and no published chisel mode. The other six have no award. None of these scores is a lab test.
Bosch Professional GBH 18V-18
Close to the corded kit at about £122.95, with 4.6 from 141, if you already own a Bosch Professional 18 V or AMPShare pack. A new battery removes that saving, and there is no chisel mode.
