GBH 18 V-LI rotary hammer

The GBH 18 V-LI is a cordless rotary hammer manufactured by Bosch as part of the Bosch Professional product line.

The machine has a brushed electric motor powered by a 18 volt battery.

According to Bosch it us the lightest Bosch rotary hammer in the 18 V SDS plus cordless category, which makes it particularly suitable for overhead use.

Despite making claims about its weight Bosch does not specify the weight of this machine on their UK website but other online stores report that the machine weighs 1900 gram with a battery but do not specify which battery.

Exterior

The machine has a blue plastic body with black parts and the controls have red accents. The machine has a D-shaped handle placed behind the motor.

Above the handle is a red switch to reverse the turning direction. On front of the handle is a large red trigger switch that can be pressed down with two fingers.

The battery is inserted by sliding in from behind and is placed under the handle on the bottom of the machine.

Above that is the angled motor housing with various horizontal ventilation slits on the sides and the Bosch logo and model name.

Towards the top on the front is a gearbox with a mode dial on the left side to select the work mode.

At the very front is an SDS Plus chuck in which drills or chisels are inserted.

Just below the chuck is a white LED that is angled upwards to illuminate the working area.

Operation

The machine is activated by pressing the variable speed trigger switch. The push button above it can be used to reverse the turning direction or as a trigger lock when the button is centered.

The black knob on the left side is used to select between drilling and drilling plus hammering for hard masonry materials like concrete.
