Circlip Pliers Knipex 49 21 A01

The Knipex 49 21 A01 Circlip Pliers are precision-made pliers for fitting and removing internal circlips. Manufactured from chrome vanadium electric steel with forged, oil-hardened construction, these pliers offer durable performance and a lightweight 130 mm length for controlled handling. Inserted tips are made from drawn spring steel wire and are designed for reliable long-term use.

Advantages

Inserted tips with additional reinforcement provide up to ten times longer service life in continuous operation than turned tips, while large contact faces prevent distortion of circlips and simplify fitting. The bolted joint ensures precise, zero-backlash operation, and the internal opening spring is protected and captive. Non-slip plastic-coated handles improve grip and control for precise work.

Suitable for

• Installing and removing internal circlips in mechanical assemblies
• Precision maintenance and repair tasks in workshops
• DIY projects requiring reliable circlip handling

How to use

Select the correct pliers orientation and position the inserted tips into the circlip holes. Squeeze the handles evenly to compress the circlip and remove or fit it into the groove. Use steady, controlled pressure to avoid slipping; the large contact faces on the tips help prevent circlip distortion. After use, release the handles slowly so the internal spring returns the jaws to the open position.

Usage recommendations

For reliable long-term performance, keep the bolted joint clean and lightly lubricated, inspect inserted tips for wear before continuous heavy-duty use, and store the pliers in a dry place to prevent corrosion.
