Butt-ended circlip pliers are used for the following purposes:

• Removing and installing external circlips that hold components like bearings, gears, and pulleys in place
• Fitting into tight spaces where the circlip is installed
• Providing a secure grip on the circlip to allow it to be expanded or compressed for removal or installation

To use a butt-ended circlip plier, the pointed jaws are inserted into the gap between the circlip and the groove. The plier is then squeezed to expand or compress the circlip, allowing it to be removed or installed. The angled jaws and PVC-coated handles provide leverage and comfort during this process. Butt-ended circlip pliers are commonly used in automotive repair, machinery maintenance, and other applications where circlips are used to secure components.
