Precision Internal Circlip Pliers

Knipex 48 21 J21 pliers are built for technicians and engineers who install or remove internal retaining rings on bores from 3/4 in to 2 3/8 in. Chrome vanadium steel construction and a 90 degree tip angle deliver the rigidity required for precise assembly and maintenance work.

Hand-operated tool with no external power

The screw joint allows fine adjustment to the ring size, reducing the force needed to spread the circlip. Spring steel wire inserted tips with a .078 in diameter grip the ring securely, minimising slippage and hand fatigue during repetitive tasks.

Replaces fixed-tip or loose-joint pliers

The adjustable screw joint eliminates the need for multiple dedicated sizes, while the inserted tips outlast stamped alternatives on small-bore applications. The jump is worthwhile when bore access is tight and repeatable tip alignment prevents ring damage.

Questions about this item

How do I adjust the screw joint on the 48 21 J21 pliers for different bore sizes?

Turn the screw joint to open or close the tips until they match the circlip holes, then lock the setting before inserting the pliers into the bore.

When will the spring steel wire inserted tips need replacement?

Replace the tips when the 0.078 in diameter shows visible wear, deformation or no longer seats securely in the circlip holes.

What bore size range stops me from using these pliers on larger rings?

The working range ends at 2 3/8 in bore diameter; rings larger than that require a different size of internal circlip pliers.
