Knipex 46 21 A01 External Retaining Ring Pliers 5 in

Product Description

The KNIPEX 46 21 A01 is a 5-inch external retaining ring pliers designed for installing and removing external circlips on shafts and rotating components. The tool features a 90-degree bent nose with a fixed 0.90 mm tip, allowing access in tight or angled applications where straight-nose pliers cannot reach. The forged steel body is oil-hardened for durability under repeated use. The plastic handles provide a non-slip grip during service. This tool is sized for ring diameters from 1/8 inch to 25/64 inch and is a standard choice for mechanical technicians, machinists, and field service professionals working on motors, gearboxes, and bearing assemblies.

The 46 21 A01 is suited for light mechanical work where external retaining rings secure bearings, pulleys, or shaft-mounted components. The 90-degree head angle makes it practical for recessed bores, confined housings, and assemblies where direct inline access is limited. At 5 inches overall length, it fits comfortably in a standard tool pouch and is appropriate for both bench work and field service. The fixed tip style means no interchangeable inserts are required. This tool meets DIN 5254 B standards, making it appropriate for professional and production environments that require certified tooling.

Installation Notes

Always relieve tension on the assembly and secure the workpiece before installing or removing retaining rings. Use proper eye protection, as rings can release under spring tension. This tool is not tether capable and should not be used in elevated work environments where dropped tools are a hazard. Inspect the tip for wear before use, as a damaged tip can slip and distort the ring.
