At a stated 2.6 J, the GBH 18V-26 hits harder than the other six machines in this comparison. It sits on AMPShare, the alliance that opens the largest tool catalogue off a single battery. It is the strongest combination in the panel, and it is priced accordingly.

All five criteria could be calculated. Weighting: Impact energy 40 %, Concrete drilling capacity 20 %, Blows per minute 15 %, Platform catalogue size 15 %, Price per joule 10 %.
Choose it if
- Regular drilling into reinforced concrete, beyond simple anchor holes.
- A jobsite where one battery has to run machines from other manufacturers.
- Work where hammer rate and capacity matter more than the entry price.
Skip it if
- A tight budget: three machines here cost less per joule.
- Occasional use: the power reserve does not pay for itself over a few holes a year.
- A workshop already committed to another platform: the cost of leaving exceeds the performance gap.

Frequently asked questions
Which battery does the Bosch GBH 18V-26 run on?
The Bosch GBH 18V-26 runs on the Bosch Professional AMPShare platform. Another brand's battery will not fit without a third-party adapter, and we advise against adapters on a two-handed hammer.
Where does this machine's score come from?
It is calculated, not awarded. Five measurable criteria are weighted, and each value is mapped onto a scale relative to the other machines in the comparison. For this machine, 100% of the scale could be applied: criteria the maker does not publish drop out rather than being replaced by an estimate.
Is the price shown for the bare tool?
We look for the bare machine first, without battery or charger, so prices stay comparable across brands. When no bare tool listing is found, the item retained is named under the price.
