The Bosch FlexiClick 12 V system is now more powerful than ever before: The new GSR 12V-35 FC Professional cordless drill/driver guarantees a high degree of efficiency thanks to its brushless motor. This makes the tool more efficient, long-lasting and maintenance free as well. The GSR 12V-35 FC Professional works at up to 1,750 revolutions per minute, making it 35 percent faster than the previous model. The tool has a high torque of 35 newtonmeter for hard screwdriving applications and 20 newtonmeter for soft screwdriving applications, ensuring that your work progresses quickly. The 32-millimeter drilling diameter in wood is 70 percent larger and the maximum screw diameter is now 8 millimeters. This makes the tool suitable for an even wider application range. The GSR 12V-35 FC Professional is 17 millimeters shorter than the previous model. With four adapters – a bit holder with bit locking as well as a drill chuck, an off-set angle and an angle adapter – it is the most versatile and most compact system in the market. The four adapters enable a total of eight possible configurations: Bosch is the only manufacturer whose angle adapter can be combined and used with any of the other three adapters. It is also unique in that the off-set angle and angle adapters can be adjusted directly on the tool: Sixteen working positions can be set without having to detach the FlexiClick adapter from the drill/driver. Carpenters, kitchen fitters, furniture makers, trade fair booth fitters and installers can therefore save time and work even more flexibly in hard-to-reach areas.

The FlexiClick 5-in-1 12 V system at a glance

At just 115 millimeters in length, the GSR 12V-35 FC Professional is the shortest cordless drill/driver in its class. This makes it the ideal problem solver in hard-to-reach areas. It has a magnetic bit holder and can therefore be used without any adapters. The tool is also equipped with a belt clip and a larger softgrip area, making your work even more comfortable. You can connect the drill/driver to the required adapter in just a few movements: Simply place the adapter onto the FlexiClick interface and turn the locking ring clockwise. A click and a control indicator on the adapter confirm that both components are reliably connected.

The bit holder, drill chuck, off-set angle and angle adapter offer tried-and-tested benefits: The GFA 12-X Professional bit holder has a hexagonal mounting with a bit lock to ensure that no bits come loose accidentally. With the bit holder, the GSR 12V-35 FC Professional is now only 144 millimeters in length and is therefore still the shortest model on the market. The GFA 12-B Professional drill chuck adapter has an auto-lock function and can be used for drill bits between one and ten millimeters. Including drill chuck adapter, the cordless drill/driver is just 162 millimeters long and allows you to drill in tight spaces. The GFA 12-E Professional off-set angle adapter allows for precise screw-driving close to edges. You just have 12 millimeters to the edge. Sixteen working positions can be set without having to detach the FlexiClick attachment from the cordless drill/driver. The same is true for the GFA 12-W Professional angle adapter. At just 61 millimeters long, it is the shortest angle adapter in its class.

Additional fixed chuck version for even more precise drilling in tight spaces

In addition to the FlexiClick screwdriver, Bosch is introducing a version with a fixed chuck, the GSR 12V-35 Professional. Measuring 154 millimeters in length, it is the shortest and most powerful fixed chuck drill/driver in the 12 V range and allows users to drive screws even more precisely. Advantages such as the brushless motor, speed of up to 1,750 revolutions per minute and torque of 35 newtonmeter for hard screwdriving applications mean that the tool stands out when it comes to drilling in metal and wood.

The GSR 12V-35 Professional fixed chuck version is available now. The Flexi-Click 12V-35 FC Professional drill/driver will be available from June. All specified prices are recommended retail prices excluding VAT.
