This is the fixed chuck version of Bosch's GBH 2-28. It keeps the 3.2 J impact energy and the KickBack and Vibration Control systems of the F model, but drops the swap over keyless chuck. The result is a slightly lighter, simpler SDS plus hammer that comes in a stackable L-BOXX. It suits users who drill masonry and do not need to switch to round shank bits.

In its favour
- The listing states 3.2 J of impact energy and calls it the strongest in Bosch's 2 kg SDS plus class.
- KickBack Control and Vibration Control are both listed for this 240 V model.
- Supplied in an L-BOXX 136 with an inlay, auxiliary handle and 210 mm depth stop.
Good to know
- No keyless chuck is included, so round shank bits need an adaptor bought separately.
- The listing does not give a concrete drilling capacity or list the operating modes.
Our take
Performance figures
Bosch lists 3.2 J of impact energy and an 880 W motor in the title, with 900 rpm in the specs. It describes the tool as the strongest rotary hammer in its 2 kg SDS plus category. The supply is stated as 240 V, which suits UK sockets.
The listing gives a weight of 3.24 kg, a little under the GBH 2-28 F.
Control systems
KickBack Control is listed to cut power when the bit jams and the tool starts to rotate. Vibration Control is there to reduce strain over long sessions. Both are useful on a hammer with this much impact energy, particularly when drilling near rebar or with long bits.
For a homeowner this may sound like more than is needed, but the same systems make a difference when drilling into old, hard brick where bits tend to wander and grab. A tool that cuts out rather than twisting is easier to keep under control on a ladder.
L-BOXX and accessories
The L-BOXX 136 comes with a fitted inlay, so the drill, handle and depth stop sit in place. It clips onto other Bosch L-BOXX cases. You also get an auxiliary handle, a 210 mm depth stop and a machine cloth.
There is no keyless chuck. If you occasionally need a wood or metal bit, an SDS plus to round shank adaptor is a cheap add on, though it adds length.
Choosing between the Bosch hammers
The GBH 2-28 F adds the quick change keyless chuck for mixed materials. The GBH 2-26 is a lower energy option at 2.7 J with a simpler case. The GBH 2-28 suits buyers who want maximum hitting power in a tidy storage system and who keep a separate drill driver for timber. The Makita HR2631FT13 is the alternative if you prefer anti-vibration and an included bit set.
Verdict
Pick the GBH 2-28 if your work is mostly masonry and you want 3.2 J with kickback protection in an L-BOXX. If you switch between masonry and timber bits through the day, the GBH 2-28 F is worth the extra, and the GBH 2-26 suits lighter, occasional use.
