Circlip Pliers Knipex 48 21 J31

The Knipex 48 21 J31 Circlip Pliers are precision hand tools manufactured from chrome vanadium electric steel with forged, oil-hardened construction. At 210 mm length and 265 g weight, they combine durability with comfortable handling. The pliers feature inserted tips made of drawn spring steel wire and non-slip plastic-coated handles for secure grip during use.

Advantages

Inserted tips extend service life and provide reliable performance in continuous operation, offering up to 10 times longer wear life compared to turned tips. A bolted joint ensures precise, zero-backlash movement of the pliers, while the chrome vanadium oil-hardened body gives mechanical strength and corrosion resistance. Plastic-coated handles improve grip and control.

How to use

Select the correct tip orientation for internal or external circlips and place the tips into the circlip eyes. Squeeze the handles gently and steadily to expand or compress the circlip as required, then remove or fit the circlip while maintaining control of the tool. Release pressure slowly to avoid sudden movement of the circlip. Keep fingers clear of the working area and maintain a firm grip on the plastic-coated handles.

Usage recommendations

Do not apply the pliers to damaged or excessively worn circlips. Regularly inspect the inserted tips for wear and replace them if they show deformation or significant wear. Store the pliers dry and apply a light lubricant to the bolted joint periodically to preserve smooth, zero-backlash operation.
