KNIPEX 49 41 A11 Precision External Circlip Pliers

KNIPEX 49 41 A11 Precision External Circlip Pliers
The KNIPEX 49 41 A11 Precision External Circlip Pliers are premium German-engineered tools specially designed for installing and removing external circlips sized 10-25 mm. This model features 90-degree angled tips, allowing technicians to reach into tight spaces or obstructed workpieces with ease. A key highlight is the adjustable overexpansion guard (limiter screw), which prevents excessive opening force that could distort or damage the retaining rings.
The plier body is forged from chrome vanadium electric steel and oil-hardened using a special process. The tips are made of high-density spring steel wire inserted into the joint, offering up to 10 times longer service life compared to conventional pliers. Ideal for assembly line production and professional technician work demanding high precision.
Features
90° Angled Tips: Easily access tight spaces, corners, or obstructed workpieces.
Overexpansion Guard: Adjustable opening limit via a stop screw to prevent ring damage from overexpansion, supporting series assembly adhering to DIN 471 standards.
Precision Tips: 1.3 mm tips with broad contact surfaces prevent circlips from twisting and slipping during use.
Chrome Vanadium Steel (Cr-V): Special grade material with a grey atramentized finish, resistant to rust and durable for heavy-duty work.
Bolted Joint: Ensures smooth and natural opening and closing without wobbling or play.
Captive Spring: Designed with the spring enclosed inside the joint to prevent dust buildup, reduce wear, and avoid losing the spring.
Non-Slip Grip: Coated with textured plastic for a secure, non-slip hold.
