Precision Internal Circlip Pliers
Knipex 48 21 J01 pliers are designed for installing and removing internal retaining rings. The tool suits technicians who work on gearboxes, pumps or small-bore assemblies where ring access is limited. A 90-degree tip angle and 0.035 in tip diameter match standard internal circlip grooves. The atramentized phosphate finish resists corrosion in workshop environments.
Upgrade from basic snap-ring tools
Spring-steel inserted tips replace stamped jaws that deform after repeated use. The bolted joint maintains alignment when spreading rings up to the 13 mm maximum bore. The jump is worth it when a slipped tip could damage a housing or when a job requires dozens of cycles without tip wear. Plastic cushion grips reduce hand fatigue during extended sessions.
Install and use with minimal setup
No adjustment is needed; the manual jaw opening is operated by hand pressure alone. Tips are not replaceable, so the tool is discarded once tip wear affects grip. The pliers are not tether-ready and lack ESD-safe handles, so they are unsuitable for height-safety or static-sensitive environments. Overall length is 5 1/8 in for tight access.

Questions about this item
What is the minimum bore diameter these pliers can work with?
The pliers are designed for internal circlips in bores as small as 8 mm.
How are the tips secured and what is the correct orientation for installation?
Tips are spring steel wire inserts held by a bolted joint; the 90-degree tip angle must face the bore wall to engage the circlip correctly.
When will the tips need replacement and how is it done?
Replaceable tips are not offered; worn or damaged tips require replacing the entire pliers.
