Pliers Knipex 97 53 09 Steel Blue Red 190mm 486g

The Knipex 97 53 09 pliers are a calibrated, self-adjusting crimping tool designed for end sleeves (ferrules) according to DIN 46228 parts 1 and 4. Manufactured from chrome vanadium electric steel with oil hardening, the tool measures 190 mm and weighs 486 g. It features front loading for ferrules, a toggle lever for efficient force transmission and reduced operator fatigue, and an integral lock with a self-releasing mechanism for repetitive, consistent crimps.

Advantages

Self-adjusting dies prevent incorrect crimps by adapting automatically to the required ferrule size, and the tool fits all twin ferrules within its application range. The crimping pressure is precisely set at the factory and can be re-adjusted if needed. The combination of calibrated pressure, toggle lever mechanics and a lightweight, ergonomic shape provides reliable, fatigue-reduced operation and consistently high crimp quality.

Suitable for

• Crimping end sleeves (ferrules) to DIN 46228 parts 1 and 4
• Electrical installation and wiring work requiring secure conductor terminations
• Professional and DIY applications needing repeatable, calibrated crimps

How to use

Insert the appropriate end sleeve (ferrule) into the front-loading opening. Position the conductor into the ferrule and close the handles firmly until the integral lock releases, ensuring a full calibrated crimp. If necessary, verify the crimp quality and readjust the calibrated pressure following the manufacturer's instructions. Store the pliers dry and clean after use to maintain the calibrated setting and tool condition.

Recommendations

Use the Knipex 97 53 09 pliers only for the specified DIN 46228 ferrules and within the tool's application range. Regularly inspect and, if required, recalibrate the crimping pressure to maintain consistent results. Avoid using the tool on materials or ferrule types not covered by the standard.
