Indexable cutting tools perform like traditional cutting tools but have a tool body or toolholder that accepts replaceable indexable inserts or exchangeable heads to form a cutting edge. The inserts and heads can be swapped out for new ones of the same type or different types without removing the tool body or toolholder from the machine. Indexable cutting tools are used on milling machines, lathes, or turning machines to remove material in milling, holemaking, threading, boring, parting, grooving, and turning operations. They require fewer tool changes than solid tools in high-volume metalworking and fabrication applications with high speeds, high feeds, and difficult-to-machine materials.
