ES-215L1 is a direct plug-in lever start torque screwdriver (1.76 – 13.2 in-lbs) with a slip/cushion type clutch. The slip/cushion clutch slips once the pre-set torque is reached. This feels like a slight release of pressure on the bit of the screwdriver. The torque setting is set by adjusting the stepless torque adjuster at the bit end of the screwdriver.
Common usages for this screwdriver are tapping screws and applications with less stringent torque control requirements.
