Why choose it

KNIPEX builds these pliers for daily professional use. The chrome vanadium electric steel body is oil-hardened for lasting toughness, while the grey atramentized finish resists corrosion. The slim head design reaches into tight bores, and the precision tips grip circlip eyelets securely, reducing the risk of slipping or scratching surrounding surfaces. The plastic-coated handles provide a comfortable, secure hold even when hands are oily. The internal opening spring returns the pliers to the open position automatically, speeding up repetitive work.

Ideal use cases

• Installing and removing internal circlips in gearboxes, transmissions, and wheel hubs
• Maintenance and repair of industrial machinery, pumps, and motors
• Assembly work in production lines where retaining rings are common
• Precision mechanical tasks requiring reliable access to bores from 19 to 60 mm

Good to know

These pliers comply with DIN 5256 C, Form J, ensuring consistent quality and compatibility. The straight tips are made from drawn spring steel wire for high strength and resilience. Always select the correct tip size for the circlip eyelets to avoid damage. Store in a dry place to maintain the finish. KNIPEX offers a wide range of replacement tips and other circlip plier variants for different applications.
