KNIPEX 49 31 A1 Precision External Circlip Pliers

KNIPEX 49 31 A1 Precision External Circlip Pliers
The KNIPEX 49 31 A1 Precision External Circlip Pliers are German-standard professional tools specifically engineered for installing and removing 10-25 mm external circlips. This model stands out with an adjustable Overexpansion Guard mechanism using a screw stop, effectively preventing circlips from being over-stretched, deformed, or damaged. Forged and oil-hardened from chrome vanadium electric steel, the inserted tips are made of high-density spring steel wire, offering up to 10 times longer service life compared to conventional circlip pliers. Featuring an internal captive spring and a bolted joint, they provide smooth, precise operation built for continuous heavy-duty use.
Features
Overexpansion Guard: Screw-adjustable stop mechanism prevents circlips from being overexpanded and damaged, ideal for series production requiring consistent standards (conforming to DIN 471)
Precision Straight Tips: 1.3 mm tips with a large contact area to prevent rings from twisting and slipping during gripping
Chrome Vanadium Steel (Cr-V): Made from specially hardened steel with a grey atramentized finish, highly durable and rust-resistant
Bolted Joint: Delivers smooth, precise plier movement with zero backlash
Captive Spring: Opening spring integrated inside the joint, protected from dirt, reducing wear, and eliminating the risk of spring loss
Non-Slip Plastic Coating Handles: Textured plastic-coated handles provide a secure grip that won't slip out of hands
