The Bosch AdvancedImpact 18V has a knock function, so that you not only drill in wood and metal, but also in harder materials, such as stone. Thanks to the automatic speed adjustment you have the right speed for every job. Thanks to the built-in LED lighting you can easily continue working in the evening or in dark places. The drill works on battery (2 batteries included as standard), which you also use on other Bosch tools with the same battery platform . The brushless motor ensures that less heat is released, which means that the drill has a longer service life. After use, store the cordless drill in the included storage case.
