Indexable inserts are an important component of indexable tools, providing multiple cutting edges that can be easily replaced or repositioned. Compared to welded and integral tools, indexable tools offer significant advantages. In this article, we will delve into the concept of indexable tools, explore their characteristics and highlight their advantages over welded tools.

Basic concepts of indexable tools:
An indexable tool is a tool that uses mechanical clamping to securely clamp a pre-machined polygonal insert with multiple cutting edges to the tool body. When one cutting edge becomes dull during use, the clamping is released, allowing the insert to be indexed or replaced. By positioning the new cutting edge in the working position, the tool can continue to be used after re-clamping.

Features of indexable tools:
Compared to welded and integral tools, indexable tools have two main features:

a) Multiple cutting edges: The insert mounted on the tool body has at least two pre-machined cutting edges available for use. This feature allows efficient use of the tool, as when one cutting edge becomes dull, it can be indexed or replaced while maintaining the same geometrical parameters.

b) Fixed cutting edge position: The position of the cutting edge on the tool body remains constant after indexing of the insert. This stability ensures consistent cutting performance and eliminates the need for readjustment, saving time for tool changes and increasing machine availability.
