Overview
The Knipex 46 11 A1 is a precision circlip plier for internal retaining rings, built with straight tips to reach into bores and housings. At 3.12 ounces it's light enough for repeated use in tight mechanical work.
Knipex's 46 series covers circlip pliers built specifically for installing and removing retaining rings, and the internal, straight tip configuration on this model is meant for rings seated inside a bore or housing rather than around an external shaft. That makes it a fit for mechanics and technicians working on gearboxes, bearings and similar assemblies where circlips hold parts in place.
- Internal circlip pliers
- Straight tip design
- 3.12 ounce weight
- Plastic covered handles
Who it's for
Suits mechanics, technicians and hobbyists who regularly work with internal retaining rings in bores or housings. Not the right choice for external circlips on shafts, which need a different tip style, or for general purpose gripping tasks.
Strengths and trade-offs
Drawn from this product's published specifications.
- Purpose built for internal circlip work
- Straight tips reach into bores and housings
- Light weight for repeated precision use
- Only works on internal rings, not external ones
- Requires matching the correct ring size range
- Not a substitute for a general purpose plier
Performance notes
Circlip pliers like this one work by spreading the plier tips apart to compress an internal retaining ring, letting it slide in or out of its groove inside a bore. The straight tip design on this model is built to reach directly into that bore, which is why it's specific to internal rings rather than the external, shaft mounted type.
