Bosch Professional GSB 20-2 Impact Drill 850 W in L-Case

Designed for demanding construction and renovation work, the 850 W Bosch Professional Impact Drill is a corded mains tool. It offers both standard rotary drilling and hammer drilling modes, so it can handle common building materials such as concrete, stone, masonry, wood, and steel. The adjustable speed control lets users match the bit rotation to the task, and drawing AC power directly from the mains keeps the motor running consistently during longer sessions. This makes the machine equally suited to clean drilling in timber and heavy-duty penetration in blockwork.

Bits are held by a quick-clamping chuck for fast changes on site. An auxiliary handle attaches to the front collar to improve stability during high-resistance applications, and using both hands helps control reactive forces when boring into dense materials. At 2,600 g, the complete unit stays manageable for horizontal and vertical drilling. The drill comes in a dedicated L-Boxx, which protects the equipment between jobs and makes it easier to carry between work areas.
