Best Bosch rotary hammer

Updated: 22 October 2026

You searched for the best Bosch rotary hammer and the results named a GBH 2-20, a two-battery kit, or a 5.0 star line from three reviews. This page stays inside the ten amazon.co.uk listings and names one top pick and one best value, with a skip for each. Prices and the score table are on the [Bosch rotary hammer comparison](/hub/drilling-and-accessories/bosch-rotary-hammer). A qualifying Amazon purchase can earn us a commission at no extra cost to you. The Products Compared editorial team prepared this on 22 October 2026 from the UK listings. There is no lab test, and a model that is not one of these ten rows is not a pick here.

What best can mean inside this set

Best, on this page, means a job match with a review sample you can read, not a laboratory rank. The top pick is the corded PBH 2100 RE at £59.94, with 4.6 from 1,683 reviews, for plugs and light chasing. The best value is the 230 V GBH 2-21 at £120.15: 2.0 J, concrete up to 22 mm, 6, 8 and 10 mm SDS-plus bits and a case, at 4.6 from 122 reviews. Skip the PBH if you need ordinary round-shank bits, or a whole tiled floor. Skip the 230 V GBH 2-21 for a checked 110 V site lead, or a ladder with no socket. The order of those checks is on the Bosch rotary hammer buying guide.

A corded home hammer and a complete green kit

Reviewers describe the PBH on brick, breeze block and concrete, including wall plugs, cement chasing and fence-post fixings. The bullets name four modes. The amazon impact cell is empty. Bosch's DIY page for model 06033A9370 prints 1.7 J and 20 mm concrete, and that figure stays on Bosch's page. The listing calls the chuck keyless, while reviews say SDS-plus bits are required. The only box with a battery and a charger is the UniversalHammer kit at £132.60: one PBA 18V 2.5 Ah pack, an AL 18V-20 and a case, 2.0 J and concrete up to 16 mm. A cell also prints 3000 mAh. The bare body at £97.92 is cheaper only when a green pack is already on the shelf.

A blue body when the packs are already on the shelf

If you already own Professional 18 V packs, the GBH 18V-22 at £180.99 is closer than either green hammer. The title names 6 mm to 10 mm holes, 4.6 from 523 reviews, in an L-BOXX with no battery. Reviewers describe kitchen and bathroom fitting and easier work on a ladder. Chiselling is not in the bullets. Bosch's GB page states 1.9 J and an optimum around 4 mm to 12 mm. That is Bosch's figure, not an amazon cell. Skip this body if the shelf has no blue pack, because £180.99 does not run on the day it arrives. Which packs fit which colour is on the Bosch green or professional rotary hammer page.

Star lines that do not pick a winner

The UniversalHammer body's 4.7 from 332 reviews is a strong cordless sample on a carton with no battery. The GBH 18V-18 X at 4.3 from 55 reviews is the lowest star line here. Stars do not repair a missing battery, a missing chisel mode, or a cell that fights the title. If your job is still a plug on a house socket and you will buy SDS-plus bits, the top pick stays the PBH. If you want the blue kit with bits and a case, the best value stays the 230 V GBH 2-21.

Common questions

Which listing is the pick if I already own blue 18 V packs?
The GBH 18V-22 at £180.99, in an L-BOXX and with no battery in the scope line. The title names 6 mm to 10 mm holes, and 523 reviews sit behind a 4.6 star line. It is a poor buy for serious chiselling, which the bullets do not name, and a poor buy if those packs are green. Green packs do not run a GBH.
Why is the cheapest blue body not the best value?
The GBH 18V-18 X is £116.95 and includes no battery, no charger and no case. The bullets do not name chiselling, and the star line is 4.3 from 55 reviews. Best value here is the 230 V GBH 2-21 at £120.15, a working corded kit with bits and a case. A bare-body sticker is only cheap if the packs are already paid for.
Is the GBH 2-28 the top pick because it costs the most and prints 3.2 J?
No. It is the joule step in this set, at £253.21, for harder drilling than a 2.0 J GBH 2-21. The sample is 4.4 from 20 reviews. The title says 240 V and 880 W, and the cells say 230 V and 850 W. For plug holes, that price and that sample do not beat the PBH or the 230 V GBH 2-21.
Can I treat 5.0 from three reviews as a winner?
No. That star line is the GBH 2-21 titled 110 V, at £134.99. Two written reviews name no fault, which is too small a sample to describe the tool. The voltage cell says 220 V. A five-star average on three ratings does not tell you which plug is in the carton. Check the plate, or buy the 230 V sister if the socket is a normal 13 A house socket.
Are the battery kits I see on amazon.co.uk the same rows as this set?
Not automatically. A search for the GBH 18V-22 also shows kit ASINs with packs that are not rows here. This page only names the ten listings, including the L-BOXX body at £180.99 with no battery. Two 4.0 Ah packs on screen are a different product, and not the top pick or the best value named here.
