Bidding on a Sumake Electric Torque Screwdriver. Model: ES-618LH1.

ES-618LH1 is a direct plug-in lever start torque screwdriver (4.4 –  15.84 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.
