Clește de sertizat combinat Knipex 97 78 180

Crimping tool for end sleeves (ferrules) to DIN 46228 parts 1 and 4, suitable for conductor cross-sections from 0.25 to 16 mm². The tool has an improved leverage mechanism and a light, slim design to facilitate handling. Crimping takes place in marked half‑round dies to ensure reliable connections between sleeve and conductor. The tool includes nine particularly deep dies with conical side faces and is made of special forged, oil‑hardened tool steel.

Advantages

The improved leverage reduces the manual force required for crimping, while the light and slim construction improves accessibility in confined spaces. Marked half‑round dies provide consistent, reliable crimps, and the nine deep conical dies accommodate a wide range of ferrule sizes. Forged, oil‑hardened tool steel ensures long service life and resistance to wear.

Suitable for

• Crimping insulated and uninsulated end sleeves/ferrules to DIN 46228 parts 1 + 4
• Electrical installation work in panels, switchgear and control cabinets
• Maintenance and repair of electrical connections in industrial and domestic applications
• Electrical workshops and field service where compact tools are required

How to use

Strip the conductor to the appropriate length, insert the ferrule onto the conductor, and position the ferrule between the marked half‑round dies that correspond to the ferrule size. Squeeze the handles evenly until the crimp is complete and the ferrule is securely attached to the conductor. Verify the mechanical and electrical integrity of the crimped connection before use.

Recommendations

Use the tool only with ferrules conforming to DIN 46228 parts 1 and 4 and within the specified cross‑section range (0.25–16 mm²). Regularly inspect the dies for wear and keep the pivot points lightly lubricated to maintain performance and service life.
