The SF 8M cordless drill driver has been designed for metalworking, while the SF 10W has been especially developed for woodworking. Both driver drills are based on a 22-volt platform and feature a rugged metal chuck, making it suitable for extreme applications as well. Thanks to its powerful four-speed gear box, the torque can be precisely adjusted to the material thickness and drill-bit diameter. The rubberised grip ensures a low transfer of vibration to the hand. The LED lamp at the lower end of the grip optimally illuminates the working area.
