Circlip pliers are a type of pliers designed for removing and installing circlips, which are a common type of retaining ring. For more information see: What is a circlip?
Circlip pliers may also be known as snap ring pliers or retaining ring pliers.
The two basic designs of circlip pliers are ones for use with internal circlips and ones for use with external circlips. Some circlip pliers can switch between internal and external and there are a number of variations available in the design of the tips and handles.
Individual pliers are only designed to work with circlips of specific diameters, so it’s important to check the specifications to ensure you select the correct pair.
You can find standard circlip pliers for use with circlips of diameters between 0.5mm (0.02 inch) and 400mm (15.8 inch), and heavy duty tools for circlips up to 1000mm (39.4 inch).
The main difference between standard pliers and circlip pliers is the tip design. Circlip pliers have specially shaped tips which can grip circlips so they can be removed or installed safely, whereas most standard pliers usually have flattened tips, for gripping, or sharp tips for cutting.
