  • Lever Start, Push to Start
  • Torque range: 44.2 – 221.2 in-lb 
  • R.P.M: 40 – 400

The Sumake SMT-250I is a Transducer DC Screwdriver with a brushless motor and a torque range of 44.2 – 221.2  in-lbs.   The SMT-250I with the SMT-C1B smart controller enables operators to track tightening status, set up different tightening parameters (torque/thread/time) and transfer data a variety of different ways. Users may switch between multiple programs to achieve various tightening tasks. Operators can easily set-up and operate from the panel or PC, and setting can be locked up using passwords.

The SMT-250I should be paired with SMT-C1B Control Unit.
