Bosch GBH18V-26 SDS-Plus Rotary Hammer

A good SDS-Plus rotary hammer should feel powerful without becoming a lump to carry around all day. For concrete drilling, masonry work and light chiselling, balance matters almost as much as impact performance.
I own the Bosch GBH18V-26, and it has proved to be a very capable drill. The 18V brushless setup gives it the sort of solid, purposeful feel you want from an SDS machine, while the two 4Ah CORE18V batteries keep the kit practical for regular site use without making the tool unnecessarily heavy.
Why it makes sense for concrete and masonry work
The Bosch GBH18V-26 makes sense when a conventional drill starts to feel out of its depth. For repeated holes in concrete, masonry fixings and light chiselling, the SDS-Plus system gives the tool a much more purposeful way of transferring impact energy into the work.
The 18V brushless motor keeps the package cordless without turning it into an oversized machine, and the two 4Ah CORE18V batteries give useful working flexibility between charges.
From my own use, this is the sort of drill that feels properly at home on harder masonry jobs. It has enough authority for serious work, but it is still manageable enough to carry and use regularly rather than feeling like a demolition tool.
What it should feel like to use
The Bosch GBH18V-26 feels compact for the amount of work it can handle. With a 4Ah CORE18V battery fitted, the tool stays better balanced than it would with a much larger pack hanging off the back.
The side handle gives useful control when drilling into concrete, while the SDS-Plus chuck keeps bit changes quick and straightforward. For repeated anchor holes or masonry work, that combination of grip, balance and cordless freedom makes the drill easier to live with over a full job.
From my own experience, it feels solid without being excessively heavy. You still know you are holding a proper rotary hammer, but it does not feel cumbersome in the way a larger SDS-Max machine can.
The drawbacks
The Bosch GBH18V-26 is powerful enough for serious masonry work, but that also means it is more drill than many occasional users need. For small wall plugs, light fixing work and softer materials, a compact combi drill will be quicker to grab and less tiring.
Battery weight is another consideration. The 4Ah CORE18V packs keep the balance sensible, but this is still a substantial cordless rotary hammer. Repeated overhead drilling can become tiring, especially once a longer bit and side handle are fitted.
It is also important to stay within the SDS-Plus class. This drill is well suited to concrete drilling and light chiselling, but heavier breaking work and larger diameter holes are where an SDS-Max machine starts to make more sense.
Finally, anyone not already invested in Bosch’s 18V platform needs to consider the battery system as part of the purchase. The supplied batteries make this kit complete, but future replacements and additional Bosch tools will naturally tie the user further into that platform.
Who it suits best
The Bosch GBH18V-26 is best suited to professional tradespeople, installers and serious DIY users who regularly drill into concrete, brick and masonry.
It makes particular sense for anyone who wants cordless SDS-Plus performance without stepping up to a larger, heavier SDS-Max machine, especially if they already use Bosch 18V tools.
It is less suitable for occasional light drilling, where a combi drill is easier to handle, or for heavy demolition work that really calls for a bigger class of rotary hammer.
Is it worth a place in the power tool kit?
For anyone who regularly drills concrete or masonry, the Bosch GBH18V-26 earns its place by combining proper SDS-Plus performance with a compact cordless format.
Its main strength is balance. It has enough power for serious anchor drilling and light chiselling, but it remains manageable enough for everyday site work, especially with the 4Ah CORE18V batteries.
The compromise is that it sits between two simpler choices. A combi drill is lighter for small fixing work, while heavier demolition or larger drilling jobs really belong to SDS-Max.
For regular concrete and masonry work, though, this is a very capable middle ground and one I have found genuinely useful in my own kit.
