GBH 18V-26 D rotary hammer
The GBH 18V-26 D is a cordless rotary hammer manufactured by Bosch as part of the Bosch Professional product line.
The machine has a brushless electric motor powered by a 18 volt battery.
According to Bosch the maximum diameter for drilling in concrete is 26 mm, but the optimal range for this machine is 8 to 16 mm.
Although the name is similar to the GBH 18V-26 it has a completely different body shape. The D at the end of the model name indicates that it has a D-handle placed behind the motor housing making the machine longer. According to Bosch this makes the machine more suitable for vertical drilling; for example in the floor or ceiling.
Exterior
The machine has a blue plastic body with black front half 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 three fingers.
The 18 volt battery is inserted from the front and is placed under the handle on the back of the machine. At the front is a white LED shines forward to illuminate the working area.
In front of the handle is the motor housing with the Bosch logo and model name printed on the side.
The front half of the body consists out of a black gearbox with a mode dial on the left side to select the work mode. In front of that is a collar with an auxiliary handle and a depth gauge.
At the very front is an SDS Plus chuck in which drills or chisels are inserted.
Operation
The machine is activated by pressing the variable speed trigger switch. The red toggle button above the handle 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 the work mode. The knob has four settings:
- Drilling for materials like soft masonry, wood and metal.
- Drilling plus hammering for hard masonry like concrete.
- Chuck adjustment mode allows the chuck to be rotated into another position to adjust the angle of a chisel.
- Hammer only for chiseling and demolition.
Safety
The machine has built in vibration reduction feature to reduce operator fatigue and two features that Bosch calls kickback control and electronic precision control.
Dust extraction
An optional dust extraction unit with model name GDE 16 plus and GDE 68 can be used with this machine.
