About Cutting tools with inserts (indexable tools)
Cutting tools are often designed with inserts or replaceable tips (tipped tools).
In these, the cutting edge consists of a separate piece of material, either brazed, welded or clamped on to the tool body.
Common materials for tips include tungsten carbide, polycrystalline diamond, and cubic boron nitride.
Tools using inserts include milling cutters (endmills, fly cutters), tool bits, and saw blades.
