KNIPEX 9K 00 80 18 US Snap Ring Pliers Set, Internal and External

For service-field work involving circlips in both bore holes and on shafts, having the right plier type for each job keeps the task straightforward. The KNIPEX 9K 00 80 18 US set brings those two functions together.

It includes one internal straight snap ring plier and one external straight snap ring plier. Use the internal tool for circlips in bores and the external tool for circlips on shafts.

Need to handle both types of installation or removal? This set covers each with a dedicated tool rather than asking one plier to do both jobs.

Strengths

The practical advantage is the pairing: internal circlip pliers are intended for fitting or removing rings in bore holes, while external circlip pliers are intended for work on shafts. That makes the set useful for service tasks where the circlip location can vary, and means the tools are selected for the job at hand.

Both pliers are straight and measure 7-1/4 inches as described for the set. The internal plier has solid, non-slip tips forged as one part of the tool. It is specified for fitting snap rings in bores ranging from 3/4" to 2 23/64". The external plier is specified for snap rings on shafts in the same stated range. These details help match the tools to common circlip work without confusing internal and external applications.

Key points

The two tools have distinct uses: the internal plier serves bore holes, and the external plier serves shafts. For a maintenance task involving both kinds of retaining ring, that pairing gives you the appropriate straight plier for each application. If your work only involves one type, choosing a single-purpose plier is another approach, this set is intended for jobs that call for both.

The manufacturer identifies the internal tool as model 44 11 J2 and the external tool as model 46 11 A2. The internal tool is described as a solid, forged design with black atramentized finish and straight, non-slip tips. The set’s listed grip type is ergonomic, and its handles are plastic. Together, these details describe a purpose-built hand-tool set for circlip installation and removal rather than a general-purpose plier set.

Buyers commonly praise the pliers’ sturdiness, durability and function. Feedback on value for money is mixed, so the clearest reason to choose this set is its two-tool coverage for internal and external snap ring work.

Who it’s for

This set suits service and repair work where retaining rings need to be installed or removed in both bores and on shafts. For example, when a job moves from a circlip seated inside a bore to one fitted around a shaft, the internal and external pliers provide the corresponding tool for each step. The specified 3/4" to 2 23/64" range gives a useful fit reference when selecting it for a task.

Worth considering if your work regularly switches between internal and external circlips and you want both straight plier types in one set. Its value is in that practical pairing, not in adding unrelated tools to the kit.

Final verdict

The KNIPEX 9K 00 80 18 US is a focused choice for circlip work across bore holes and shafts. With one internal and one external straight plier, it gives service-field users a clear tool for each application, plus a stated snap-ring range of 3/4" to 2 23/64" for both. Choose it when that two-sided coverage matches the retaining-ring work you do.
