Why Pulsing Tools Will Revolutionize DC Tooling Landscape

Assembly workers using handheld powered tightening tools are repetitively subjected to reaction loads. Direct Drive tools create a reaction into the operators’ hands because the tools’ motor directly connects to the output shaft. The operator absorbs a “kick-back” from the tool when it delivers torque to the fastener.


Avoid injuries and limit reaction force

To avoid operator discomfort or injuries, we recommend not to use Direct Drive tools above certain thresholds (without the use of a reaction arm)

Straight tool : ~2Nm
Pistol tool: ~10Nm
Angle tool: ~50Nm

ESTIC - Patented Pulsing Technology

Estic patented “Pulse” technology reduces the reaction force to a minimum during tightening job.

Thanks to ESTIC’s patented motor control system, pulse fastening technology has achieved an unprecedented reduction in reaction forces. 

Cordless nut runners are equipped with ESTIC’s patented pulse tightening technology, so work can be done with minimal reaction to the operator. The ESTIC cordless tools can fasten up to 100N・m.


01 Pulse Fastening
By tightening using intermittent impact force like hitting with a hammer, users receive little reaction force.


02 Direct Fastening
Tightening by continuous motion, users receive a large reaction force.
