The SF 2 marks the compact performance class within the product family of SF cordless devices, which includes a drill driver and an impact driver. These tools are mainly used by carpenters, who routinely work in awkward positions and on valuable materials, relying on small and light tools with precise handling. The shape of the SF 2 devices provides user-specific ergonomics for this purpose. The tools are well balanced and sit firmly in the hand. To prevent damage, the torque automatically adjusts to the underlying surface.
