Hydraulic crimping tool

Start by matching the tool’s crimp range to your typical cables. The options shown cover cross-sections from 4–70 mm² up to 16–240 mm² and 16–300 mm², so pick a model that comfortably handles your largest cables without overloading. Look for high crimping force—around 70 kN is common in these tools—and practical features that speed work, such as a 360° rotating head for tight spaces and an auto-release valve for faster cycles. Interchangeable dies and a protective storage case help keep dies compatible and organized between projects.

Interchangeable dies are the heart of the system. They determine the exact shape and size of the crimp for different cable cross-sections and terminal types, so your tool can terminate copper cables accurately across a range. In common kits you’ll find dies sized for 16, 25, 35, 50, 70, 95, 120, 150, 185 and 240 mm², with a set of dies included or available separately. Choose dies that match your most frequent cables and crimps to ensure consistent, reliable connections and avoid overcrimping or undercrimping.

Electricians and contractors performing on-site terminations will appreciate ergonomic handles and a rotating head that reaches tight spots. Maintenance technicians in workshops benefit from interchangeable dies for different cable types and a durable storage case to keep tools organized between jobs. Together these features reduce fatigue, improve crimp precision, and help you complete terminations faster while maintaining a professional finish.

After use, wipe the tool clean and inspect the die area for wear. Store it in the included case to protect the dies and prevent loss. Keep the interchangeable dies with the tool and verify compatibility with your current cables before you crimp; some models ship with a sealing O-ring set for replacements. Regular checks of die alignment and compatibility ensure consistent crimps and extend the tool’s service life.

These hydraulic crimpers are designed for professional electrical installations involving copper conductors and lugs. They cover cross-sections from 16 mm² up to 300 mm² in many configurations and accommodate a wide range of terminals. For best results, match the cable size to the dies and confirm the tool’s force rating is sufficient for your conductor. A case and versatility in crimping heads make fieldwork more efficient and reliable.

Look for features that speed up field work, such as an auto release valve for quick cycling, a 360° rotating head to reach awkward angles, and a lightweight, ergonomic grip to reduce fatigue during extended use. Also consider whether the tool includes a durable storage case and a comprehensive set of dies to cover your typical cable and terminal types, which minimizes downtime between projects.
