Four-piece internal and external set

This Knipex retaining-ring plier set contains four pliers designed for both internal and external circlips. The tips are angled at 0 degrees and 90 degrees to reach snap rings in different orientations. Each plier uses a spring-return jaw opening for consistent operation. The set is aimed at technicians who service bearings, gearboxes and hydraulic cylinders.

Spring return limits continuous force

The spring-return mechanism automatically opens the jaws after each squeeze, which speeds repetitive work but limits the sustained clamping force you can apply. Tip diameter is fixed at 0.078 in, so the pliers only fit grooves that accept that size. The atramentized finish resists corrosion but does not increase tip hardness beyond the base chrome-vanadium steel.

Bore range 3/4 to 2 23/64 in

The decisive specification is the bore-diameter capacity of 3/4 in to 2 23/64 in for internal rings and a matching shaft range of 3/4 in to 2 3/8 in for external rings. If your retaining rings fall outside these diameters, the tips will not engage the lug holes securely. Buyers who need larger or smaller ring sizes must choose a different set.

Questions about this item

Which plier tips suit internal versus external rings in this 4-piece set?

Two pliers have 0-degree tips for internal bores from 3/4 to 2 23/64 in, and two have 90-degree tips for external shafts from 3/4 to 2 3/8 in, covering both ring types.

What does the 0.078 in tip diameter mean when I fit a circlip?

The 0.078 in tips engage standard circlip holes on shafts and bores within the listed diameter ranges, giving positive grip without spreading the ring excessively.

How does the spring-return jaw affect repetitive use?

Spring-return jaws automatically reopen after each squeeze, reducing hand fatigue during repeated internal or external ring installation and removal.
