Internal pliers open to release a ring sitting inside a bore and external pliers close to release one on a shaft. The two actions are opposite, so the type is established from the circlip itself before any size is considered. Looking at the circlip first rather than the shaft or bore is what makes this straightforward.
Getting that wrong is immediately obvious but the tool is often bought before the job is looked at. A workshop meeting both regularly holds both, which is why sets pairing internal and external pliers exist rather than only individual tools. Sets also cover the tip angles a single plier cannot, which is where most of the awkward jobs sit.
Tip angle decides whether the plier reaches the circlip at all. A straight tip approaches head on. A 90 degree tip enters from the side, which is the only route where the bore or shaft sits behind something that cannot be moved. Both tip angles are held in internal and external forms so the reach does not restrict the type.
Plier length gives reach and control, running 130mm, 140mm, 170mm, 180mm, 225mm and 320mm here. Tip diameter has to match the holes in the circlip, and a tip too large will not enter while one too small slips out under load.
