Knipex Internal Precision Circlip Pliers
Knipex 4811J1 precision internal circlip pliers for fitting and removing circlips inside bore holes in the 12–25mm diameter range. This is the internal counterpart to the external precision circlip range already in the Knipex listings, where the 4911 series handles circlips on shafts, the 4811J1 handles circlips seated inside bores, the format found in wheel bearings, engine components, gearbox housings, and hydraulic assemblies where the circlip seats in a groove inside a bore rather than around the outside of a shaft. The same precision series features apply throughout; inserted spring steel tips for up to 10 times longer service life than turned tips, a zero-backlash bolted joint, and large contact faces that hold the circlip securely without distortion.

Knipex Internal Precision Circlip Pliers
- Internal bore format — a distinct and important capability from the external range — The 4811J1 is designed specifically for circlips seated inside bores rather than on shafts; the tip geometry opens outward to engage internal circlip mounting holes, which is the opposite action from external pliers and requires a completely different tool; wheel bearing housings, gearbox casings, engine bores, and hydraulic cylinder assemblies are the environments where internal circlips appear regularly and where this tool earns its place
- 12–25mm bore range covers the most common internal circlip sizes — The bore range spans the sizes most frequently encountered in automotive, light mechanical, and general engineering applications; wheel bearing circlips, small hydraulic cylinder retaining rings, and light gearbox assembly work all fall within this range, making the J1 the practical everyday internal circlip pliers for the broadest range of workshop tasks
- Inserted spring steel tips for up to 10 times longer service life — The 1.3mm diameter tips are cold-formed from high-density spring steel wire and positively inserted into the base tips, delivering up to 10 times the service life of conventional turned tips in continuous operation; at the 12–25mm bore scale where tips are fine and the loads concentrated, the durability of the spring steel format over a turned alternative is particularly significant
- Large contact faces prevent circlip distortion on installation and removal — The large, straight contact surfaces behind the non-slip angled tips distribute load evenly across the circlip mounting holes; at the smaller bore sizes within the J1 range where circlips are delicate and the margin for distortion is narrow, that even load distribution is what keeps the circlip undamaged and correctly formed through the fitting process
- Zero-backlash bolted joint for precise control in confined bores — The bolted joint delivers smooth operation with zero backlash, which in internal bore work is particularly valuable — guiding tips into circlip mounting holes inside a bore requires precise control that a loose or backlash-affected joint makes significantly more difficult; the bolted construction maintains that precision consistently across the working life of the tool
- Chrome vanadium electric steel body, forged and oil-hardened — The pliers body is manufactured from chrome vanadium electric steel, forged and oil-hardened, with non-slip plastic coating on the handles; the captive internal opening spring keeps the pliers open and ready between installations without loss or interference in workshop environments
