Pinza per anelli di sicurezza Knipex 49 11 A0

The Knipex 49 11 A0 Circlip Pliers are precision pliers for installing and removing circlips. Constructed from forged, oil‑hardened chrome vanadium electric steel with drawn spring steel inserted tips and non‑slip plastic handles, these 140 mm pliers weigh 101 g and are intended for reliable, long‑life service in continuous use.

Advantages

Inserted tips provide reliable work and large contact faces that prevent distortion of circlips and make fitting easier. The bolted joint ensures precise, zero‑backlash operation. An internal opening spring is protected and captive, and the pliers body is made from durable, forged chrome‑vanadium steel with an oil‑hardening treatment. A non‑slip plastic coating on the handles improves grip during use.

How to use

Select the correct pliers orientation for internal or external circlips. Position the inserted tips over the circlip ends, squeeze the handles gently to expand or compress the circlip, then remove or insert the circlip into its groove. Release the handles slowly to avoid sudden movement. Keep fingers clear of the circlip path and ensure a secure grip on the handles for controlled operation.

Recommendations

For reliable performance, inspect the inserted tips before use and replace pliers if tips are worn or damaged. Avoid using the pliers for cutting or as a hammer; use them only for circlip manipulation. Clean and lightly lubricate the bolted joint periodically to maintain precise operation.
