SF 2 is the sub-compact power class within the SF family of cordless tools, including a drill driver and impact wrench. Preferred by professional carpenters who routinely work in awkward positions and on valuable materials, this class must be light, small and easy to control precisely. The SF 2 design responds with user-specific ergonomics: a well-balanced body which is contoured to sit firmly in the craftsperson’s hand. This improves handling, while a new stepless trigger can intuitively adjust torque to prevent damage to the base material.
