Nitto Kohki’s “delvo” electric screwdrivers are high-quality tools for professional use, with special emphasis on precise torque control and long-term reliability. “delvo” gives you the ability to get it right, every time.

Repeatable Accuracy
Brushless motors
Designed to provide more consistent torque, screw after screw. No brushes to replace and a wide torque range allow brushless screwdrivers to be used in various applications for extended periods of time.
Reduced Recoil
Sophisticated clutches and a motor braking system reduce the hand recoil at the end of the screw tightening operation, reducing user fatigue. High-speed motors cut down on screw tightening time and enhance productivity.
Brushless electric screwdrivers assure you a long operating life. Compare “delvo” to conventional pneumatic screwdrivers and you will hear the difference.

World-class innovation with precision torque control.
More than 35 years experience world higest quality
