The Bosch GSH 5 is a compact SDS max chisel hammer for jobs where a heavy floor breaker is too much. Bosch describes it as lightweight and compact for horizontal or overhead work, with a D shaped grip and a switch lock for continuous use. At a listed 5.6 kg, it suits tilers, electricians and renovators who chase walls and lift tiles rather than break slabs.

Our take
Size and power
The listing gives 1,100 W at 230 V and a weight of 5.6 kg. Bosch claims high power and impact energy for a strong start when chiselling, although the listing does not give a joule figure. In practice, this class of tool is aimed at tiles, render, plaster and light concrete rather than thick reinforced slabs.
Vario-Lock and handling
Vario-Lock gives 12 positions for setting the chisel angle, so a tile chisel can sit flat to the floor or a channel chisel can align with a chase line. An extra D shaped grip improves ergonomics, and a switch lock lets you run the tool without holding the trigger, which reduces hand strain on long spells of chiselling.
Where it works best
The low weight is the main reason to choose the GSH 5. Working horizontally on walls or above head height with a 10 kg breaker quickly becomes exhausting. A 5.6 kg tool is far easier to hold in position for chasing cables, removing wall tiles or knocking off render.
For breaking floors, a heavier hammer like the Makita HM1213C does more of the work through its own weight.
In the box
Bosch lists an additional grip, a carrying case, a cloth for the machine, a grease tube and a pointed chisel. That means you can start breaking straight away. The listing does not mention a vibration control system, which some rivals list.
Alternatives
The Makita HM1213C is the heavier breaker for floors. If you need to drill as well as chisel, a combination hammer such as the HiKOKI DH40MC or Makita HR4013C covers both. The GSH 5 is for chisel work where weight is the priority.
Verdict
Pick the GSH 5 if you mainly chase walls, lift tiles and break render, and want a light SDS max chisel hammer you can hold at any angle. For heavy floor breaking, the Makita HM1213C is stronger, and if you also need to drill large holes, the HiKOKI DH40MC is a combination hammer that does both.
