What is an indexable cutting tool characterized by?

An indexable cutting tool is characterized by multiple cutting edges, which is a key feature that distinguishes it from other types of cutting tools. This design allows for the use of several edges on a single tool insert, significantly enhancing the tool's efficiency and lifespan. When one edge becomes worn or damaged, it can be indexed, or rotated, to expose a fresh edge, minimizing downtime for tool replacement and maximizing productivity in machining operations.

In industrial settings, the ability to use multiple cutting edges makes indexable tools highly economical and versatile for various metal cutting applications. This characteristic facilitates continuous operation and contributes to more efficient material removal rates. Additionally, having multiple cutting edges allows for better distribution of wear among the edges, further extending the tool life.

The other options relate to different types of cutting tools or characteristics not applicable to indexable tools. For instance, single cutting edges are typical of tools like drills and some lathe tools, fixed position cutting implies a more static approach that is not representative of the flexibility indexable tools offer, and elastic cutting edges are not a standard design feature of cutting tools, as they do not provide the necessary rigidity for effective machining.
