Atlas Copco ETD SL21-04-I06-PS Electric Nutrunner

Atlas Copco ETD SL21-04-I06-PS is a compact electric straight nutrunner from the Tensor SL family, engineered for precise, repeatable fastener driving in light assembly work. It delivers 0.8–4 Nm of torque at speeds up to 1600 rpm, powered by a 140 W motor at 35 V, and weighs about 0.7 kg (1.6 lb) with a total length of 246 mm, making it well suited for tight workspace applications. The tool uses a 1/4" (6.35 mm) hex drive (female) and a center-to-spindle distance of 18–19.5 mm, enabling compatibility with common small fasteners. Its transducer-based shut-off system provides torque control for consistent results and traceability, and the unit carries KC- and EAC-certifications for regional compliance. Designed in a straight configuration, this ETD model features a hex output and a 1/4" bit size, aligning with standard electronics, automotive interior, and appliance fastener tasks. With a 3-phase AC motor and a compact form factor, the ETD SL21-04-I06-PS supports high-repeatability operations in both automated and semi-automated production setups where controlled torque is essential.
