Cordless Torque Wrench DA3docu

Precise fastening. Digital documentation.

The DA3docu cordless nutrunner combines powerful and precise fastening with modern digital documentation. Designed for industrial assembly, maintenance, and service applications, it enables controlled fastening of large screw connections while also laying the foundation for transparent and traceable work processes.

In addition to the proven features of the DA3 platform, the DA3docu enables the transmission of fastening data via Wi-Fi to common digital devices such as tablets or smartphones. Fastening results can thus be documented and evaluated directly at the worksite – on the go, efficiently, and without a wired data connection.

Cordless torque wrench with Wi-Fi documentation for traceable fastening processes

Documentation as a Source of Added Value for Quality and Transparency

The focus of DA3docu is the simple and practical documentation of bolting processes. The relevant bolting data can be transmitted via Wi-Fi to common digital devices such as tablets or smartphones. This allows bolting results to be tracked and evaluated directly on-site.

Digital documentation supports transparent workflows, particularly for quality-critical assembly, service, and maintenance tasks, and provides a traceable basis for evaluating completed bolting operations.

Rugged, secure, and intuitive for mobile use

The DA3 docu was developed for demanding industrial applications. The optimized gearbox, designed for continuous loads, is slimmer, shorter, and lighter, while the 4-speed transmission supports optimal operating speed. At the same time, the modern BLDC motor technology ensures high energy efficiency, a long service life, and precise speed and torque control.

The automatic, infinitely variable 360° swivel joint and the ergonomic dual trigger ensure added safety and comfortable operation. The swivel joint reduces the risk of getting caught, while the two-handed operation minimizes the risk of injury. Key settings can be adjusted directly on the device via the integrated display and intuitive menu navigation.

Position within the DA3 product family

The DA3 docu is the documentation-capable variant within the new DA3 product family. It builds on the functions of the DA3 power and adds digital documentation and WLAN transmission of fastening data to the precise torque-controlled fastening.

For users who also need advanced tightening strategies, the DA3control complements the platform with torque-angle and angle-only methods. As a result, the DA3 series offers a common, future-proof platform for a wide range of requirements – from precise standard fastening to documented and advanced-control fastening processes.
