KWB 403900 is a 4-piece circlip pliers set designed for removing and installing internal and external circlips. The set contains tools sized and shaped to work with a range of ring diameters and profiles, providing controlled opening and closing of clips during assembly and repair. Its design prioritizes precise grip and reduced slippage to help complete workshop, automotive and maintenance tasks more efficiently.

Advantages

The set combines internal and external circlip pliers to cover common clip jobs without the need to change tools frequently. Ergonomically shaped handles improve hand comfort and control during repetitive use. Hardened jaws and tips maintain their shape under load, ensuring reliable engagement with circlips and minimizing deformation of the rings.

How to use

Select the appropriate internal or external pliers from the set that match the circlip type and diameter. Position the tips into the circlip holes or behind the ring edges, then squeeze the handles to open or compress the clip as required. Maintain steady pressure and a straight tool orientation to avoid slippage; carefully remove or fit the circlip to the shaft or groove. After use, clean and store the pliers in a dry place to prevent corrosion and preserve tip geometry.

Recommendations

Use eye protection when working with circlips to guard against unexpected release. Choose the pliers size that offers the best fit for the specific clip to reduce deformation. Avoid using the pliers as general-purpose cutting or prying tools to preserve the hardened tips and ensure long service life.
