GDR 18V-210 C impact driver
The GDR 18V-210 C is a cordless impact driver manufactured by Bosch as part of the Bosch Professional product line.
The machine has a brushless electric motor that is powered by a 18 volt battery.
With a maximum torque of 210 Nm for tightening this machine is suitable for nuts and bolts with threads of M6 up to M16.
Exterior
The tool has a blue plastic housing with black rubber mostly around the handle and along the back and the rear of the top side. The handle is placed in the middle under the motor for better tool balance.
The battery slides in from the front under the handle and there is an optional metal belt hook attached to the side with a screw.
At the bottom of the handle is a white LED that illuminates the working area. The LED will automatically turn on. Around the LED are some membrane buttons with indicator LEDs to change the work mode.
In front of the motor housing is an aluminum hammer case and tapers towards the front where it is covered in black rubber.
At the very front there is the 1/4" hex bit holder with a black ribbed sleeve that can be puled to release the bit.
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.
On the bottom of the handle there is a membrane button to cycle though the following power mode. The lower settings can be used on smaller screw diameters and prevent over tightening or breaking fasteners.
- 80 Nm, 1100 RPM, 2200 BPM
- 160 Nm, 2300 RPM, 3300 BPM
- 210 Nm, 3400 RPM, 4100 BPM
Next to the speed button is a work mode button which can toggle between A and B. The settings can be configured using a mobile phone with Bluetooth connectivity. The user manual does not specify what work modes are possible but the quick start guide shows various settings for slowing down and stopping automatically to prevent damage to the fastener.
Bluetooth connectivity
The machine has a built-in wireless communication module in the handle that uses Bluetooth to connect to the Bosch Toolbox app on a smartphone to adjust some settings.
The module is located behind a round over on the right side of the handle (not visible in picture). The cover can be opened by twisting it with a coin. The module can be removed so that the machine can also be used in environments where wireless communications are restricted.
