The impact drills of this high-performance class are designed for professional use. The SF 6 class shares a uniform, well-thought-out concept with the other SF classes and impresses with task-specific ergonomic features, high performance and long battery life. The newly developed brushless motor delivers strong torque and high speeds at low power consumption. The full metal housing of the gear unit and the non-slip, shock-absorbing surfaces ensure a secure grip and protect against the rough environment of construction sites.
