Firmly grip, dismantle and fit concealed large internal circlips

Accurate and stable, forged tips for an ideal hold

Strong, accurately machined pliers tips are crucial when fitting and removing large circlips, e.g. in mechanical engineering and motor construction. The installation holes in the circlips offer the tips of circlip pliers little room for manoeuvre and friction surface. The tips must overcome the high ring tension and hold the circlip securely after removal or before insertion. This places high demands on the accuracy and stability of the pliers tips. With the Knipex 44 21 J31, the handle and tips are forged in one piece, which produces correspondingly high durability. The very accurately twisted tips are also machined so they slant inwards slightly. As a result, the circlips are held tightly on the pliers tips.

Reinforced, measured manual force precisely into the installation holes

With circlips pliers, the measurable force that reaches the component is just one of many parameters. Of prime importance is that the manual force is applied to the component in an accurate, well-measured manner. This applies especially to circlips, because the circlips are under tension when fitted and removed. Thanks to quality machining, balanced tool geometry and precise joint, manual force reaches the circlip on the Knipex 44 21 J31 in a manner that enables the user to work in the best way: accurately, and gentle on hands. With a length of 215 mm, the Knipex 44 21 J31 has sufficient leverage for large circlips.

Poorly accessible circlips can be reached well thanks to angled tips

Strong circlips pliers such as the Knipex 44 21 J31 are ideal, e.g. in farming, in engine manufacturing and mechanical engineering. They are narrow at the front and at a 90° angle for ideal access also to circlips that are difficult to reach. The pliers sit comfortably in the hand, can be positioned accurately in the circlip installation holes and hold the circlips firmly. Working with first-class circlips pliers such as the Knipex 44 21 J31 saves a great deal of time, as anyone who has tried to extract a circlip on a piston pin from a drilled hole using makeshift tools will know. Having to search the workshop for a circlip because the tips of poorly machined circlip pliers have failed to hold it well can also take a long time. With the Knipex 44 21 J31, every circlip and every hand movement sits properly.
