Internal Circlip Pliers for Precision Work

These Knipex retaining-ring pliers are built for technicians who install or remove internal circlips in bores from 12 mm to 25 mm. The 45-degree angled tips reach into tight housings where straight jaws cannot. Chrome vanadium electric steel construction withstands repeated professional use.

Atramentized Finish Resists Corrosion and Glare

The phosphate coating reduces surface reflection under bright workshop lighting while protecting the steel from rust. Standard cushion grips absorb hand pressure during repetitive tasks without adding bulk. Manual jaw opening gives direct tactile control over tip spread.

Nonslip Tips Hold Rings Securely During Removal

Precision-machined .051 in tips grip circlip lugs firmly, reducing the risk of the ring flying loose. Tips are not replaceable and the tool is not tether-ready, so users who need lanyard attachment or field-serviceable tips should select a different model. No ESD-safe rating is provided.

Questions about this item

How do I fit the 0.049 inch tips into a 12 mm bore at 45 degrees?

Open the handles, insert the angled tips into the internal circlip holes, then squeeze to expand the ring; the 45-degree bend lets you reach around obstructions without twisting the wrist.

Will the phosphate-coated jaws or plastic grips need replacement over time?

The atramentized finish resists corrosion, and the cushion grips are bonded to the handles; neither is designed to be user-replaceable, so the tool is used until wear makes the tips unreliable.

At what bore size do the 0.051 inch tips start to lose grip on internal rings?

The pliers are rated for 12 mm to 25 mm bores; beyond 25 mm the tips cannot reach the circlip holes securely, so that upper limit is reached first under sustained use.
