Circlip pliers Knipex 44 21 J11, chromium-vanadium steel, 130 mm, plastic handles

Knipex 44 21 J11 is a 130 mm circlip pliers engineered for installing and removing internal and external circlips with a working range from 8 to 140 mm diameter. Manufactured from forged chromium‑vanadium steel with oil hardening and a corrosion‑resistant finish, the pliers combine a compact length with solid, non‑slip tips and ergonomic plastic handles to support precise handling in confined spaces. The tool weighs 88 g and is intended for mechanical maintenance, automotive repair and general assembly tasks where reliable circlip control is required.

Advantages

The forged chrome‑vanadium steel body and tips provide high strength and wear resistance while the oil‑hardening process increases durability. Solid, non‑slip tips ensure secure engagement with internal and external circlips, reducing the risk of slippage during fitting or removal. Plastic ergonomic handles improve grip comfort and control during repetitive tasks. The compact 130 mm length allows access in tight assemblies and the corrosion‑resistant finish extends service life in workshop environments.

Suitable for

• Installing and removing internal circlips in bores with diameters from 8 to 140 mm
• Removing and fitting external circlips on shafts and housings
• Automotive repair and brake or transmission maintenance where circlips secure components
• Mechanical assembly and maintenance of small machinery and equipment

How to use

Select the correct orientation for internal or external circlips and position the tips inside or outside the circlip eyes as required. Squeeze the handles evenly to open or close the circlip until it can be fitted into or removed from the groove. Maintain a steady hand and keep the tips engaged with the circlip to avoid slipping; retract the pliers slowly once the circlip is seated or removed. Inspect the circlip and seating groove for damage before reassembly.

Usage recommendations

Use the pliers only within the specified circlip diameter range (8–140 mm). Avoid applying excessive torque or using the tool as a general prying device. Keep the tips clean and lightly lubricated to prevent corrosion and ensure reliable engagement. Wear eye protection when fitting or removing circlips to protect against sudden release.
