K-DUCER is the new class A intelligent transducer zed assembly system from Kolver, the electric tool pioneer since 1989.The system consists of an advanced state of the art controller and a range of handheld and fixtured electric screwdrivers with torque up to 50 Nm.
KDS Hand-held Screwdrivers
Finest accuracy and precision
KDS transducerized electric tools cover all assembly line requirements for an accurate, high-quality torque and angle-controlled tightening experience.
A built-in compact transducer provides torque control with excellent repeatability.
Excellent ergonomics
KDS screwdrivers feature unsurpassed ergonomics, soft touch design, status LED, temperature protection combined with full traceability and error-proofing capabilities. Available in straight, pistol and fixture configuration
Connectivity and Industry 4.0
KDS tools are the ideal solution for your Industry 4.0 production line. Integrating the K-Ducer in your smart factory will be effortless, thanks to the built-in Modbus TCP and Open Protocol connectivity. Built-in LED lights provide immediate feedback on each tightening process, i.e. you’ll be able to check at a glance whether the part is correctly tightened or not. KDS screwdrivers work in combination with KDU control units to gather, analyse and process detailed assembly information. Their built-in transducer continuously reads torque and position of the screw and sends the gathered data to the KDU controller for analysis.
INLINE (KDS-PL/ESD) – Inline versions available in lever start. ESD-safe. KDS inline screwdrivers can also be supplied with built-in LED lights (KDS-PL /LED/ESD), which light up the area underneath while in use.
PISTOL GRIP – Trigger start, pistol grip available with top connector (KDS-PL P/U/ESD) or bottom connector (KDS-PL P/ESD).ESD-safe.
ALUMINIUM HOUSING (KDS-PL ) For torques over 20 Nm, with start and reverse buttons.
ANGLE MODELS (KDS-PL ANG/ESD) Inline models with angle head attached. ESD-safe.
