Circlip Pliers Knipex 44 10 J5 Steel Handle 570 mm 1.74 kg

The Knipex 44 10 J5 Circlip Pliers are heavy-duty steel circlip pliers with a 570 mm length and a weight of 1.74 kg, designed for assembling circlips into bores with diameters from Ø 122 to 400 mm. The pliers feature a high-strength rolled steel body with a black powder coated finish and replaceable, oil-hardened special tool steel tips. A releasable locking device secures the tool during handling and transport, while the construction provides the durability and precision required for large-scale circlip installation tasks.

Advantages

Constructed from rolled, high-strength steel and equipped with oil-hardened special tool steel tips, these circlip pliers combine robustness with wear resistance. The replaceable tips extend service life and allow maintenance without replacing the entire tool. The black powder coated surface improves corrosion resistance, and the integrated locking device ensures safe handling and compact storage. The 570 mm length provides mechanical leverage for working with circlips in large bores.

Suitable for

• Assembly of internal circlips into bores with diameters Ø 122–400 mm
• Maintenance and repair work on large mechanical assemblies
• Industrial and workshop use where high-strength hand tools are required
• Situations requiring replaceable tips and a locking mechanism for safety

How to use

Position the pliers so the replaceable tips engage the circlip correctly inside the bore. Squeeze the handles to expand the circlip until it clears the groove, then carefully insert or remove the circlip as required. Use the locking device to secure the pliers when not in active use or during transport. Inspect the tips before use and replace them if worn or damaged to maintain safe and precise operation.

Usage recommendations

For safe and efficient work, wear appropriate personal protective equipment and ensure the workpiece is stable. Check tip condition regularly and replace with the correct tempered replacement tips when signs of wear appear. Clean and lightly oil the pivot area periodically to maintain smooth action and prevent corrosion.
