Cleco 50EPN125KD4 NeoTek Pistol Corded Electric Nutrunner | 455 RPM | 18.4 - 90.7 (ft-lbs) Torque Range | 1/2" Square Drive

When a fastening station needs more torque than lower-range NeoTek pistol tools can provide, the Cleco 50EPN125KD4 NeoTek pistol corded electric nutrunner delivers a 25–123 Nm / 18.4–90.7 ft-lbs torque range for controlled medium-to-high torque assembly work. It's 455 RPM free speed supports steady rundown on larger fasteners, while the 1/2" square drive fits compatible production sockets used in assembly cells, fixture stations, and line-side fastening operations. As a NeoTek tool, it is part of Cleco’s smart fastening platform, meaning the tool is built for torque control, operator feedback, and fastening process visibility rather than impact-style fastener removal.

The pistol grip configuration gives operators a stable, familiar hand position for horizontal and bench-level fastening tasks. With transducer control, digital communication, configurable LED light rings, and on-board tool memory, the 50EPN125KD4 supports production environments where torque repeatability, fastening traceability, and clear pass/fail feedback are part of the assembly process.

Features:

• 1 million cycles maintenance-free, based on the recommended tool model torque range and clockwise rotation.
• Repeatability and accuracy with 2.0 Cm/Cmk at +/- 7% for controlled production fastening.
• Transducer control measures torque directly for assembly processes that require repeatable tightening results.
• Digital communication between tool and controller helps maintain reliable fastening data transfer.
• Configurable LED light rings give operators visual status feedback during fastening cycles.
• Tactile and audible operator feedback helps confirm tool status without requiring the operator to look away from the workpiece.
• Programmable multi-function buttons allow tool behavior to be configured for the fastening station.
• On-board tool memory and preventive maintenance alerts support traceability and planned service scheduling.

Made in USA:

Applications:

• Automotive and transportation assembly — controlled tightening of brackets, housings, frame components, and medium-to-high torque joints within the specified range.
• Heavy equipment manufacturing — fastening guards, panels, machinery structures, and subassemblies where repeatable torque output is required.
• Industrial production lines — line-side nut and bolt fastening in stations that use process control, visual operator feedback, and fastening records.
• Appliance and machinery assembly — production fastening on larger components where 1/2" square drive sockets are preferred over smaller drive formats.
• MRO and tool standardization programs — use in facilities that maintain Cleco NeoTek systems and need a higher-torque pistol model for controlled assembly work.

FAQs:

• Q: What makes the 50EPN125KD4 different from lower-torque NeoTek pistol models?
  A: This model has a higher 25–123 Nm / 18.4–90.7 ft-lbs torque range and a slower 455 RPM speed. That makes it better suited for larger fasteners that need more controlled tightening force.
• Q: Is this a good replacement for an impact wrench?
  A: No. The 50EPN125KD4 is a controlled electric nutrunner for tightening fasteners to a target torque. Impact wrenches are used for general service and fastener removal, but they do not provide the same torque control or fastening traceability.
• Q: What does transducer control mean?
  A: Transducer control means the tool measures torque through an internal sensor rather than estimating torque only from motor behavior. This helps support repeatable fastening results in production assembly.
• Q: What sockets work with this tool?
  A: The tool uses a 1/2" square drive, so it accepts compatible 1/2" drive sockets. Always select sockets rated for the torque level and approved for your production fastening process.
• Q: Does the tool provide feedback to the operator?
  A: Yes. The NeoTek platform includes configurable LED light rings, tactile feedback, audible alerts, programmable buttons, and on-board tool memory to help operators and supervisors monitor fastening status.
